Children's heavy digital media use is associated with a risk of being overweight later in adolescence. A recently completed study shows that six hours of leisure-time physical activity per week at the age of 11reduces the risk of being overweight at 14 years of age associated with heavy use of digital media.
Obesity in children and adolescents is one of the most significant health-related challenges globally. A study carried out by the Folkhalsan Research Center investigated whether a link exists between the digital media use of Finnish school-age children and the risk of being overweight later in adolescence. In addition, the study looked into whether children's physical activity has an effect on this potential link.
The study involved 4, 661 children who reported how much time they spent on sedentary (久坐的)digital media use and physical activity outside school hours. The study indicated that heavy use of digital media at 11 years of age was associated with a heightened risk of being overweight at 14 years of age in children who reported engaging in under six hours per week of physical activity in their leisure time. In children who reported being physically active for six or more hours per week, such a link was not observed.
The study also took into account other factors potentially impacting obesity, such as childhood eating habits and the amount of sleep, as well as the amount of digital media use and physical activity in adolescence. In spite of the confounding(混杂的) factors, the protective role of childhood physical activity in the connection between digital media use in childhood and being overweight later in life was successfully confirmed.
"The effect of physical activity on the association between digital media use and being overweight has not been extensively investigated in follow-up studies so far, "says Postdoctoral Researcher Elina Engberg. "In this study, the amount of physical activity and use of digital media was reported by the children themselves, and the level of their activity was not surveyed, so there is a need for further studies."
1.The subjects of the study were
A. surveyed three years later after the first one
B. those who used sedentary digital media a lot
C. 4661 school -aged children suffering from obesity
D. lacking in sufficient leisure-time physical activity
2.What does the underlined word "heightened" in paragraph 3 probably mean?
A. major B. particular C. increasing D. slight
3.What was the focus of the recent study?
A. Different factors contributing to kids' overweight problem.
B. The role of childhood eating habits in dealing with children's obesity.
C. Impact of kids' exercise on the link between digital media use and obesity.
D. Teens' health-related challenges resulting from heavy digital media use.
4.What might be talked about in the following paragraph?
A. Reasons for carrying out further studies.
B. Guidelines for children and adolescents.
C. Approaches to solving teens' weight problems.
D. Connections between obesity and physical activity.

There was a lot of news related to artificial intelligence, or AI, and machine learning. Among the stories were two dealing with direct competitions between humans and machines.
In one competition, machines that used AI performed better than human beings in a high-level reading test. Two natural language processing tools beat human in the experiment. One of the tools was built by the American technology company Microsoft. The other was created by Chinese online seller Alibaba Group.
In another competition, a computer took on humans in live, public debates. The event demonstrated how AI-powered computers are increasingly being developed to think and sound like humans. The organizer of the debates, US technology company IBM, announced split results. It said a majority of those watching said they felt the machine had done more to improve their knowledge of the subject. But, the human got more praise for communicating their ideas.
This year, we also explored the many ways AI and machine learning are now being used. For example, some US judges use machine learning systems to help them decide when, and for how long, criminals should be jailed. The system uses computers to examine data from thousands of court cases.
One fast-growing area of AI is facial recognition, which is increasingly being used for security purposes. Recently, Atlanta's Hartsfield-Jackson airport became the first in the US to permit passengers to use facial recognition technology to get on flights. A Chinese company showed an AI system developed to recognize individuals by body shape and walking movements. The system is already being used by Chinese police in Beijing and Shanghai.
In addition, machine learning was used during 2018 to predict results of the World Cup soccer competition. The technology also created artwork sold for a large amount of money. And it is being used to help farmers save time and money, while reducing environment-harming chemicals. Other technology systems are being used to follow farm animals and wildlife to collect information on their activities.
1.Why were the two competitions mentioned in the passage？
A. To show how much better AI and machine learning are than humans.
B. To prove AI and machine learning got more praise for communication.
C. To show how powerful AI and machine learning are.
D. To prove AI and machine learning have been used in the work of US judges.
2.What are facial and body recognition systems used for in the passage？
A. Knowledge learning. B. Safety control. C. Office automation. D. Tracking surveys.
3.What can we infer from this passage？
A. AI has been widely used in every person's daily life.
B. Humans can be replaced by AI in future completely.
C. More attention is being paid to AI in every part of the world.
D. More advanced AI is helping people in more and more areas.
4.Where is the passage probably from？
A. A technology report. B. A natural science magazine.
C. A science fiction. D. A government document.

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.
For their study, biologist Corsin Müller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.
After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.
They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer “game” that scientists had a hard time keeping them away from the touch screens after the study was completed.
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous dog studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
1.How did the scientists conduct the experiment?
A. By leaving dogs to women who are either happy or angry.
B. By mixing the selected dogs together.
C. By rewarding only half of the dogs touching the screen.
D. By showing digital pictures of women's happy or angry faces.
2.Which of the following statements is TRUE?
A. The dogs were not all provided with the entire face.
B. According to their size, the dogs were given either upper or lower halves.
C. The dogs could read even small changes that accompany facial expressions after some training.
D. The dogs couldn't read strangers facial emotions.
3.The underlined word “trepidation” in Paragraph 5 probably means _____.
A. horror B. curiosity C. excitement D. doubt
4.How might the results change if the dogs with female owners are shown pictures of male faces?
A. They could only tell emotions on partial faces rather than on entire faces.
B. They found it hard to tell the moods on the faces of a different gender.
C. They found it easy to tell the emotions on the entire face.
D. They would be scared away at the sight of the pictures.
D.
Old age may not sound exciting. But recent findings offer good news for older people and for people worried about getting older. Researchers found that people become happier and experience less worry after they reach the age of 50. In fact, they say by the age of 85, people are happier with their life than they were when they were 18 years old.
The findings came from a survey of more than 340,000 adults in the United States. The Gallup Organization questioned them by telephone in 2008. At that time, the people were between the ages of 18 and 85. The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 24 and 25. The findings showed that stress levels dropped sharply (突然地) after people reached their fifties.
The study also showed that men and women have similar feeling patterns as they grow older.
However, women at all ages reported more sadness, stress and worry than men.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their feelings. They so spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be connected to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being (幸福) related to age.
（1）According to the survey of the Gallup Organization people are most likely to become happier.
A.when they are between the ages of 18 and 85
B.when they come to their old age
C.when they are in their twenties
D.when they are 18 years old
（2）You may have the highest level of stress when you are at the age of ______.
A.20
B.25
C.35
D.40
（3）According to Arthur Stone, old people may .
A.have a positive attitude towards their life
B.know how to spend money wisely
C.dream about good things every day
D.control their behaviors better
（4）Who would probably show the greatest interest in the passage?
A.Those who are worried about getting old
B.Those who are single and unemployed
C.Those who feel unhappy all the time
D.Those who suffer from mental stress
（5）What would be the best title for the passage?
A.Women Are Easier to Be Happy in Life
B.The Young Are Happier Than the Old
C.Getting Older Means Getting Happier
D.The Younger, the Happier

I experienced an earthquake with my friend and colleague Dawa Chhiri Sherpa last Saturday. 36. But we were lucky enough to survive it.
It was quite a usual morning at first. That morning, Dawa and I had breakfast out with his son Sonam.
37. Dawa and his son then went out to do some shopping. About an hour later, I went to the lobby of the hotel. When I was sitting there, everything slowly started to move and then all of a sudden we were being thrown around.
We managed to slowly make our way to open ground and struggled to even stand at times. There was a moment when I felt the hotel and all the buildings would come down, but they didn't. 38. I wanted to find them.
Sadly, just walking in that area was a challenge. The street was blocked. 39. After walking around the area for 45 minutes I decided to make my way back to the hotel. I waited on the open ground at the hotel. Luckily, I got a call from Dawa, saying they were safe. Four hours after the first earthquake, they got back to the hotel.
40. The first four days after the earthquake were bad —no water, food, electricity or information, as every three hours we would be rocked by tremors. By Wednesday, things were starting to go well. Dawa and I decided to go out and help people. And we did that on the following three days as well.
A. I called the hotel for help.
B. It was a horrible experience.
C. Life after the earthquake was terrible.
D. There was no sign of Dawa or Sonam.
E. We really had a terrible night that day.
F. After breakfast, Dawa took me back to my hotel.

Last week, I have the honor of experiencing teaching. Our school asked some volunteer to teach some kids which lived in the countryside.
I treasured this chance so much and joined in the team. When I met those kids, they were so happily to see me and listened to me carefully. Given the warmest welcome by them, I enjoyed being their teacher. However, I tried my best to teach them and play games with them.
Back to school, I missed our students so much. They liked me a lot but some of them even kept in the touch with me. I felt so proud being a teacher. This precious experience helped me make up my mind to realizing my dream.

【点评】考查七选五，本文是一篇故事类阅读，要求在理解细节信息的基础上，着重考查对上下文的理解和推理判断能力。
36.根据空前“I experienced an earthquake with my friend and colleague Dawa Chhiri Sherpa last Saturday.”上周六，我和我的朋友兼同事Dawa Chhiri Sherpa一起经历了一次地震；以及空后“But we were lucky enough to survive it.”但我们很幸运能活下来。可知，上文提到作者和同事经历了一次地震，后文提到他们活了下来，可推测本句承接上文说明对地震的感受。B. It was a horrible experience.“这是一次可怕的经历”符合语境，故选B。
37.根据空前“It was quite a usual morning at first. That morning, Dawa and I had breakfast out with his son Sonam.”起初，这是一个很平常的早晨。那天早上，Dawa和我和他的儿子Sonam一起出去吃早餐，可知，上文提到了作者他们在吃早餐，故本句应承接上文说明早饭之后他们的活动，F选项中breakfast对应上文中breakfast。F. After breakfast, Dawa took me back to my hotel.“早饭后，Dawa送我回旅馆”符合语境，故选F。
38.根据空前“We managed to slowly make our way to open ground and struggled to even stand at times. There was a moment when I felt the hotel and all the buildings would come down, but they didn't.”我们设法慢慢地向开阔地前进，有时甚至要挣扎着站起来。有那么一刻，我觉得酒店和所有的建筑都会倒塌，但它们没有；以及空后“I wanted to find them.”我想要找到他们，可知，后文提到了作者想要找到某些人，可知本句应是在具体说明找到谁，后文them指代G选项中Dawa and his son。G.

39.根据上文“Sadly, just walking in that area was a challenge. The street was blocked.”遗憾的是，光是在那个区域行走就是一个挑战。街道被封锁了；以及空后“After walking around the area for 45 minutes I decided to make my way back to the hotel. I waited on the open ground at the hotel. Luckily, I got a call from Dawa, saying they were safe. Four hours after the first earthquake, they got back to the hotel.”在附近走了45分钟后，我决定回到酒店。 我在旅馆的空地上等着。幸运的是，我接到了Dawa的电话，说他们很安全。第一次地震发生四小时后，他们回到了酒店。可知，上文提到街道封锁了，后文提到第一次地震发生四小时后，Dawa他们回到了酒店，可推测作者一开始在街道上没有找到Dawa或Sonam。D. There was no sign of Dawa or Sonam.“没有Dawa或Sonam的迹象”符合语境，故选D。
40.根据空后“The first four days after the earthquake were bad —no water, food, electricity or information, as every three hours we would be rocked by tremors. By Wednesday, things were starting to go well. Dawa and I decided to go out and help people. And we did that on the following three days as well.”地震后的头四天很糟糕，没有水，没有食物，没有电，也没有信息，因为每三个小时我们都会被余震震动。到周三，事情开始进展顺利。Dawa和我决定出去帮助别人。 我们在接下来的三天里也这样做了。可知，本段主要是在描述地震之后的生活艰难，C选项中after the earthquake对应后文中after the earthquake。C. Life after the earthquake was terrible.“地震后的生活很可怕”符合语境，故选C。

（5）考查主谓一致。句意：然而，超过14个小时似乎对他们的健康有害。分析句子可知，本句为一般现在时，主语为14 hours 是一个整体，所以谓语动词是单数appears 。故填appears .
（6）考查非谓语动词。句意：为了得出他们的研究结果，研究人员对1245名青少年进行了调查。分析句子可知，本句涉及have sth/sb done的用法。 teenagers在逻辑上与survey在逻辑上是被动关系，且作teenagers的宾语补足语。所以用过去分词，填surveyed。
（7）考查名词。句意：所有参与者都被要求回答有关身高、体重、体育锻炼、运动伤害和健康的问题。根据逗号和 and 并列可知，都是相同的词性，为名词，injure 的名词形式为injury/injuries。sports为名词修饰名词injury/injuries。故填injury/injuries.
（8）考查定语从句。句意：他们的健康是用“世卫组织健康指数”这个词来衡量的，该指数的得分在0到25之间。分析句子可知，Word Health Organization (WHO) Well-being Index为先行词，在后面的非限制性定语从句中作主语，所以关系代词为which。故填which .

（12）考查时态语态。句意：研究人员发现，每周进行14小时体育活动的参与者的健康得分最高，但超过14小时的参与者的健康得分较低。研究表明最高的健康值达到，表示达到用 achieve，并且与主语the highest well-being scores是被动，所以用achieved。故填 achieved .
（13）考查介词。句意：研究人员发现，每周进行14小时体育活动的参与者的健康得分最高，但超过14小时的参与者的健康得分较低。result in “导致”符合句意。故填in .
（14）考查定语从句。句意：研究人员建议，关心青少年的医生应该检查他们的体育锻炼水平。doctors为先行词在后面的定语从句中作主语，所以关系代词为who/that。故填 who/that .

（1）考查时态。句意：上周，我很荣幸地体验了教学。根据时间状语last week，可知谓语动词用一般过去时，故have 改为had。
（2）考查名词。volunteer是可数名词，其前有some修饰时要用复数形式，故volunteer改为volunteers 。
（3）考查定语从句。分析句子结构可知这是一个限制性定语从句，先行词kids在从句中作主语，用关系代词who/that，故which改为who/that 。
（4）考查形容词。句意：当我见到那些孩子时，看到我他们那么高兴，认真听我说。be动词后用形容词作表语，故happily改为happy 。
（5）考查副词。句意：受到他们最热烈的欢迎，我很高兴成为他们的老师。因此我尽力教他们，和他们一起玩游戏。后一句是前一句的结果，用副词therefore，故However改为Therefore 。
（6）考查代词。句意：回到学校，我非常想念我的学生。此处指作者的学生，故our改为my。7
（7）考查连词。句意：他们很喜欢我，有些人甚至和我保持联系。前后句是顺承关系，不是转折关系，因此but改为and。

Children's heavy digital media use is associated with a risk of being overweight later in adolescence. A recently completed study shows that six hours of leisure-time physical activity per week at the age of 11reduces the risk of being overweight at 14 years of age associated with heavy use of digital media.
Obesity in children and adolescents is one of the most significant health-related challenges globally. A study carried out by the Folkhalsan Research Center investigated whether a link exists between the digital media use of Finnish school-age children and the risk of being overweight later in adolescence. In addition, the study looked into whether children's physical activity has an effect on this potential link.
The study involved 4, 661 children who reported how much time they spent on sedentary (久坐的)digital media use and physical activity outside school hours. The study indicated that heavy use of digital media at 11 years of age was associated with a heightened risk of being overweight at 14 years of age in children who reported engaging in under six hours per week of physical activity in their leisure time. In children who reported being physically active for six or more hours per week, such a link was not observed.
The study also took into account other factors potentially impacting obesity, such as childhood eating habits and the amount of sleep, as well as the amount of digital media use and physical activity in adolescence. In spite of the confounding(混杂的) factors, the protective role of childhood physical activity in the connection between digital media use in childhood and being overweight later in life was successfully confirmed.
"The effect of physical activity on the association between digital media use and being overweight has not been extensively investigated in follow-up studies so far, "says Postdoctoral Researcher Elina Engberg. "In this study, the amount of physical activity and use of digital media was reported by the children themselves, and the level of their activity was not surveyed, so there is a need for further studies."
1.The subjects of the study were
A. surveyed three years later after the first one
B. those who used sedentary digital media a lot
C. 4661 school -aged children suffering from obesity
D. lacking in sufficient leisure-time physical activity
2.What does the underlined word "heightened" in paragraph 3 probably mean?
A. major B. particular C. increasing D. slight
3.What was the focus of the recent study?
A. Different factors contributing to kids' overweight problem.
B. The role of childhood eating habits in dealing with children's obesity.
C. Impact of kids' exercise on the link between digital media use and obesity.
D. Teens' health-related challenges resulting from heavy digital media use.
4.What might be talked about in the following paragraph?
A. Reasons for carrying out further studies.
B. Guidelines for children and adolescents.
C. Approaches to solving teens' weight problems.
D. Connections between obesity and physical activity.

There was a lot of news related to artificial intelligence, or AI, and machine learning. Among the stories were two dealing with direct competitions between humans and machines.
In one competition, machines that used AI performed better than human beings in a high-level reading test. Two natural language processing tools beat human in the experiment. One of the tools was built by the American technology company Microsoft. The other was created by Chinese online seller Alibaba Group.
In another competition, a computer took on humans in live, public debates. The event demonstrated how AI-powered computers are increasingly being developed to think and sound like humans. The organizer of the debates, US technology company IBM, announced split results. It said a majority of those watching said they felt the machine had done more to improve their knowledge of the subject. But, the human got more praise for communicating their ideas.
This year, we also explored the many ways AI and machine learning are now being used. For example, some US judges use machine learning systems to help them decide when, and for how long, criminals should be jailed. The system uses computers to examine data from thousands of court cases.
One fast-growing area of AI is facial recognition, which is increasingly being used for security purposes. Recently, Atlanta's Hartsfield-Jackson airport became the first in the US to permit passengers to use facial recognition technology to get on flights. A Chinese company showed an AI system developed to recognize individuals by body shape and walking movements. The system is already being used by Chinese police in Beijing and Shanghai.
In addition, machine learning was used during 2018 to predict results of the World Cup soccer competition. The technology also created artwork sold for a large amount of money. And it is being used to help farmers save time and money, while reducing environment-harming chemicals. Other technology systems are being used to follow farm animals and wildlife to collect information on their activities.
1.Why were the two competitions mentioned in the passage？
A. To show how much better AI and machine learning are than humans.
B. To prove AI and machine learning got more praise for communication.
C. To show how powerful AI and machine learning are.
D. To prove AI and machine learning have been used in the work of US judges.
2.What are facial and body recognition systems used for in the passage？
A. Knowledge learning. B. Safety control. C. Office automation. D. Tracking surveys.
3.What can we infer from this passage？
A. AI has been widely used in every person's daily life.
B. Humans can be replaced by AI in future completely.
C. More attention is being paid to AI in every part of the world.
D. More advanced AI is helping people in more and more areas.
4.Where is the passage probably from？
A. A technology report. B. A natural science magazine.
C. A science fiction. D. A government document.
C
While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.
For their study, biologist Corsin Müller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.
After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.
They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer “game” that scientists had a hard time keeping them away from the touch screens after the study was completed.
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous dog studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
1.How did the scientists conduct the experiment?
A. By leaving dogs to women who are either happy or angry.
B. By mixing the selected dogs together.
C. By rewarding only half of the dogs touching the screen.
D. By showing digital pictures of women's happy or angry faces.
2.Which of the following statements is TRUE?
A. The dogs were not all provided with the entire face.
B. According to their size, the dogs were given either upper or lower halves.
C. The dogs could read even small changes that accompany facial expressions after some training.
D. The dogs couldn't read strangers facial emotions.
3.The underlined word “trepidation” in Paragraph 5 probably means _____.
A. horror B. curiosity C. excitement D. doubt
4.How might the results change if the dogs with female owners are shown pictures of male faces?
A. They could only tell emotions on partial faces rather than on entire faces.
B. They found it hard to tell the moods on the faces of a different gender.
C. They found it easy to tell the emotions on the entire face.
D. They would be scared away at the sight of the pictures.
D.
Old age may not sound exciting. But recent findings offer good news for older people and for people worried about getting older. Researchers found that people become happier and experience less worry after they reach the age of 50. In fact, they say by the age of 85, people are happier with their life than they were when they were 18 years old.
The findings came from a survey of more than 340,000 adults in the United States. The Gallup Organization questioned them by telephone in 2008. At that time, the people were between the ages of 18 and 85. The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 24 and 25. The findings showed that stress levels dropped sharply (突然地) after people reached their fifties.
The study also showed that men and women have similar feeling patterns as they grow older.
However, women at all ages reported more sadness, stress and worry than men.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their feelings. They so spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be connected to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being (幸福) related to age.
（1）According to the survey of the Gallup Organization people are most likely to become happier.
A.when they are between the ages of 18 and 85
B.when they come to their old age
C.when they are in their twenties
D.when they are 18 years old
（2）You may have the highest level of stress when you are at the age of ______.
A.20
B.25
C.35
D.40
（3）According to Arthur Stone, old people may .
A.have a positive attitude towards their life
B.know how to spend money wisely
C.dream about good things every day
D.control their behaviors better
（4）Who would probably show the greatest interest in the passage?
A.Those who are worried about getting old
B.Those who are single and unemployed
C.Those who feel unhappy all the time
D.Those who suffer from mental stress
（5）What would be the best title for the passage?
A.Women Are Easier to Be Happy in Life
B.The Young Are Happier Than the Old
C.Getting Older Means Getting Happier
D.The Younger, the Happier

I experienced an earthquake with my friend and colleague Dawa Chhiri Sherpa last Saturday. 36. But we were lucky enough to survive it.
It was quite a usual morning at first. That morning, Dawa and I had breakfast out with his son Sonam.
37. Dawa and his son then went out to do some shopping. About an hour later, I went to the lobby of the hotel. When I was sitting there, everything slowly started to move and then all of a sudden we were being thrown around.
We managed to slowly make our way to open ground and struggled to even stand at times. There was a moment when I felt the hotel and all the buildings would come down, but they didn't. 38. I wanted to find them.
Sadly, just walking in that area was a challenge. The street was blocked. 39. After walking around the area for 45 minutes I decided to make my way back to the hotel. I waited on the open ground at the hotel. Luckily, I got a call from Dawa, saying they were safe. Four hours after the first earthquake, they got back to the hotel.
40. The first four days after the earthquake were bad —no water, food, electricity or information, as every three hours we would be rocked by tremors. By Wednesday, things were starting to go well. Dawa and I decided to go out and help people. And we did that on the following three days as well.
A. I called the hotel for help.
B. It was a horrible experience.
C. Life after the earthquake was terrible.
D. There was no sign of Dawa or Sonam.
E. We really had a terrible night that day.
F. After breakfast, Dawa took me back to my hotel.

Last week, I have the honor of experiencing teaching. Our school asked some volunteer to teach some kids which lived in the countryside.
I treasured this chance so much and joined in the team. When I met those kids, they were so happily to see me and listened to me carefully. Given the warmest welcome by them, I enjoyed being their teacher. However, I tried my best to teach them and play games with them.
Back to school, I missed our students so much. They liked me a lot but some of them even kept in the touch with me. I felt so proud being a teacher. This precious experience helped me make up my mind to realizing my dream.

【解析】本文是一篇说明文，一项研究表明：11岁时每周进行6小时的休闲体育活动可以降低14岁时因大量使用数字媒体而超重的风险。
【点评】本题考点涉及细节理解，词义猜测和推理判断三个题型的考查，是一健康类阅读，考生需要准确捕捉细节信息，并根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。
1.考查推理判断。根据第一段中的“A recently completed study shows that six hours of leisure-time physical activity per week at the age of 11 reduces the risk of being overweight at 14 years of age associated with heavy use of digital media.”可知，在11岁时每周进行6个小时的休闲体育活动，可以降低14岁时因过度使用数字媒体而超重的风险。要得出这个结论，说明研究人员对参与调查的学生进行了跟踪调查，分别在11岁时和14岁时进行，故选A。
2.考查词义猜测。根据第一段中的“A recently completed study shows that six hours of leisure-time physical activity per week at the age of 11 reduces the risk of being overweight at 14 years of age associated with heavy use of digital media. ”最近完成的一项研究表明，11岁时每周进行6小时的休闲体育活动可以降低14岁时因大量使用数字媒体而超重的风险；以及第三段中的“The study indicated that heavy use of digital media at 11 years of age was associated with a heightened risk of being overweight at 14 years of age in children who reported engaging in under six hours per week of physical activity in their leisure time.“这项研究表明，11岁时大量使用数字媒体与14岁时超重的heightened风险有关，这些儿童报告说，他们在闲暇时间每周进行不到6小时的体育活动。可知，研究表明，11岁时每周进行6小时的休闲体育活动可以降低14岁时因大量使用数字媒体而超重的风险，可推至如果这些儿童每周在闲暇时间进行体育活动不足6小时，那他们14岁时因大量使用数字媒体而超重的风险会增加，heightened在此处意为“增加”。故选C。
3.考查细节理解。根据第二段中的“A study carried out by the Folkhälsan Research Center investigated whether a link exists between the digital media use of Finnish school-age children and the risk of being overweight later in adolescence. In addition, the study looked into whether children’s physical activity has an effect on this potential link. ”Folkhälsan研究中心开展的一项研究调查了芬兰学龄儿童使用数字媒体与青春期后期超重风险之间是否存在联系。此外，该研究还调查了儿童的体育活动是否对这种潜在联系产生影响；以及最后一段中的“‘The effect of physical activity on the association between digital media use and being overweight has not been extensively investigated in follow-up studies so far,’ says Postdoctoral Researcher Elina Engberg.“博士后研究员Elina Engberg说：“到目前为止，在后续研究中，体育活动对数字媒体使用与超重之间关系的影响还没有得到广泛的研究。”可知，最近研究的重点是儿童锻炼对数字媒体使用与肥胖之间联系的影响。故选C。
4.考查推理判断。根据倒数第二段中“In spite of the confounding (混杂的) factors, the protective role of childhood physical activity in the connection between digital media use in childhood and being overweight later in life was successfully confirmed. ”在这些混杂的因素中，成功地证实了儿童体育活动在儿童使用数字媒体与后期超重之间的联系中的保护作用。可知，研究得出结论：体育活动能减少儿童后期因大量使用数字媒体而肥胖的风险，接下来的段落应该是全文的总结，根据研究结论，应该是就体育锻炼给孩子和青少年提建议。故选B。

3.考查词义猜测。根据第五段中的“They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewarded, the trepidation seem end to disappear.”他们认为可能是因为狗看到生气的表情后会感到厌恶，因此它们会迅速撤退。但是一旦聪明的狗意识到会有奖励之后，它们这种恐惧感就会消失。可知，生气的脸会使狗害怕而立刻远离，但是一旦得到奖励以后这种恐惧感就会消失。故选A。
4.考查推理判断。根据最后一段中的“The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. ”研究人员还注意到，只有拥有男性主人的狗更难正确理解这些表情。故选B。

【解析】本文是一篇说明文，新的研究表明和运动太少的效果一样，青少年运动太多也会对他们的健康产生消极影响。每周大约14小时的体育运动，健康得分最高，但是超过14小时的体育运动健康得分较低。
（1）考查非谓语动词。句意：青少年一直被告知积极参加体育活动对他们的健康有好处。 and 为并列连词，根据前文的 being，所以后面 take 也用 doing 的形式。故填 taking .
（2）考查形容词。句意：新的研究表明和和运动太少的效果一样，青少年运动太多也会对他们的健康产生消极影响。little修饰不可数名词sport 。too much与too little相对应。故填 little .
（3）考查形容词。句意：美国卫生与公众服务部建议6至17岁的年轻人每天至少锻炼60分钟，每周7小时。aged为过去分词作形容词作后置定语修饰 people。故填aged .
（4）考查副词。句意：美国卫生与公众服务部建议6至17岁的年轻人每天至少锻炼60分钟，每周7小时。work out 表示外出锻炼的意思。符合句意。故填out .
（5）考查主谓一致。句意：然而，超过14个小时似乎对他们的健康有害。分析句子可知，本句为一般现在时，主语为14 hours 是一个整体，所以谓语动词是单数appears 。故填appears .
（6）考查非谓语动词。句意：为了得出他们的研究结果，研究人员对1245名青少年进行了调查。分析句子可知，本句涉及have sth/sb done的用法。 teenagers在逻辑上与survey在逻辑上是被动关系，且作teenagers的宾语补足语。所以用过去分词，填surveyed。
（7）考查名词。句意：所有参与者都被要求回答有关身高、体重、体育锻炼、运动伤害和健康的问题。根据逗号和 and 并列可知，都是相同的词性，为名词，injure 的名词形式为injury/injuries。sports为名词修饰名词injury/injuries。故填injury/injuries.
（8）考查定语从句。句意：他们的健康是用“世卫组织健康指数”这个词来衡量的，该指数的得分在0到25之间。分析句子可知，Word Health Organization (WHO) Well-being Index为先行词，在后面的非限制性定语从句中作主语，所以关系代词为which。故填which .
（9）考查名词。句意：所有参与者的总体平均健康得分为17分。 overall为形容词修饰名词average且符合句意。故填average.
（10）考查形容词。句意：研究人员将运动参与者分为低、平均、高和非常高四类。由前文的 low/average/very high，可知中间是高。故填high .
（11）考查非谓语动词。句意：研究人员发现，与平均水平组的参与者相比，低活动组和高活动组的参与者的健康得分更可能低于13分。be more likely to do固定短语，“很有可能做某事”，故填to have。
（12）考查时态语态。句意：研究人员发现，每周进行14小时体育活动的参与者的健康得分最高，但超过14小时的参与者的健康得分较低。研究表明最高的健康值达到，表示达到用 achieve，并且与主语the highest well-being scores是被动，所以用achieved。故填 achieved .
（13）考查介词。句意：研究人员发现，每周进行14小时体育活动的参与者的健康得分最高，但超过14小时的参与者的健康得分较低。result in “导致”符合句意。故填in .
（14）考查定语从句。句意：研究人员建议，关心青少年的医生应该检查他们的体育锻炼水平。doctors为先行词在后面的定语从句中作主语，所以关系代词为who/that。故填 who/that .
（15）考查副词。句意：青少年可能需要更紧密地跟踪他们的健康状况。probably为副词修饰动词need。故填probably.
【点评】本题考点涉及非谓语动词，形容词，副词，主谓一致，名词，定语从句，时态语态以及介词等多个知识点的考查，是一篇健康类阅读，要求考生在理解细节信息的基础上，进一步根据上下文的逻辑关系，并结合相关语法知识，进行分析推理，从而写出正确的单词形式。

（1）考查时态。句意：上周，我很荣幸地体验了教学。根据时间状语last week，可知谓语动词用一般过去时，故have 改为had。
（2）考查名词。volunteer是可数名词，其前有some修饰时要用复数形式，故volunteer改为volunteers 。
（3）考查定语从句。分析句子结构可知这是一个限制性定语从句，先行词kids在从句中作主语，用关系代词who/that，故which改为who/that 。
（4）考查形容词。句意：当我见到那些孩子时，看到我他们那么高兴，认真听我说。be动词后用形容词作表语，故happily改为happy 。
（5）考查副词。句意：受到他们最热烈的欢迎，我很高兴成为他们的老师。因此我尽力教他们，和他们一起玩游戏。后一句是前一句的结果，用副词therefore，故However改为Therefore 。
（6）考查代词。句意：回到学校，我非常想念我的学生。此处指作者的学生，故our改为my。7
（7）考查连词。句意：他们很喜欢我，有些人甚至和我保持联系。前后句是顺承关系，不是转折关系，因此but改为and。
（8）考查冠词。keep in touch with固定短语，“与.....保持联系”，故去掉in后的the。
（9）考查介词。句意：作为一个老师，我感到非常自豪。be proud of固定短语，“为.....感到骄傲”，故在proud后加of。
（10） 考查非谓语动词。make up one's mind to do sth．固定短语，"下定决心做某事"，后接动词不定式，故realizing改为realize。
【点评】本题考点涉及时态，名词，定语从句，形容词，副词，代词，连词，冠词，介词以及非谓语动词等多个知识点的考查，是一篇故事类阅读，覆盖面广，综合性强，难度较大，区分度高。
