Ⅰ.阅读理解

(2019·陕西省部分学校摸底检测)Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic.
The experts believe the machine should be able to collect half of the detritus in the patch—about 40,000 metric tons—within five years.In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine，creating the largest floating barrier ever made.
The system，originally dreamt up by Mr.Slat，will be shipped out this summer to the Great Pacific Garbage Patch，between Hawaii and California，which contains estimated 1.8 trillion pieces of plastic.It will be the first ever attempt to tackle the patch since it was discovered in 1997.
Mr.Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea.“There were more bags than fish down there，” he recalls.Two years later he came up with a solution，quit university after six months and set up The Ocean Cleanup as a company.Mr.Slat says the first plastic to arrive on shore will be a major milestone.“We as humanity created this problem，so I think it's also our responsibility to help solve it，” he says.
The Great Pacific Garbage Patch(GPGP) covers an area of 1.6 million square kilometers and contains at least 79,000 tons of plastic，research found last month. Most of it is made up of “ghost gear” — parts of abandoned and lost fishing gear，such as nets and ropes—often from illegal fishing vessels.
Ghost gear kills more than 100,000 whales，dolphins and seals each year，according to scientific surveys.Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic.Creatures eat plastic discarded in the sea thinking it's food but then starve to death because they are not feeding properly.Others are trapped and die of starvation or are strangled or suffocated by ghost gear.
【语篇解读】 本文是一篇说明文，主要介绍了世界首个海洋垃圾清扫机的发明。
1．What does the underlined word in the second paragraph probably mean?
A．Waste. B．Ocean.
C．System. D．Machine.
A [词义猜测题。根据第二段画线词前的“collect half of”和第四段第一句中的“first saw for himself the amount of plastic polluting the sea”和第五段最后一句中的“parts of abandoned and lost fishing gear，such as nets and ropes—often from illegal fishing vessels”可推知，画线词的意思是“垃圾”。故选A。]
2．Which one makes up most of the garbage in Pacific from the passage?
A．Fishing vessels.
B．Dolphins and seals.
C．Giant tubes.
D．Abandoned fishing gear.
D [细节理解题。根据第五段最后一句“Most of it is made up of ‘ghost gear’—parts of abandoned and lost fishing gear，such as nets and ropes—often from illegal fishing vessels”可知，太平洋里的大部分垃圾是由废弃的钓鱼用具组成的。]
3．Why do some creatures in The Great Pacific Garbage Patch die of starvation?
A．Because they are killed by ghost gear.
B．Because they are suffocated by ghost gear.
C．Because they don't like eating plastic.
D．Because they are not feeding properly.
D [细节理解题。根据最后一段倒数第二句中的“but then starve to death because they are not feeding properly”可知，大太平洋垃圾带的一些生物死于饥饿是因为它们不能真正地进食。]

(2019·合肥市第二次教学质量检测)Classifying things is critical for our daily lives.For example，we have to detect spam mail(垃圾邮件)，false political news. When we use AI，such tasks are based on “classification technology” in machine learning—having the computer learn，using the boundary separating positive and negative data.For example，“positive” data would be photos including a happy face，and “negative” data photos that include a sad face.Once a classification boundary is learned，the computer can determine whether certain data are positive or negative.
However，the difficulty with this technology is that it requires both positive and negative data for the learning process，and negative data are not available in many cases.For instance，when a retailer(零售商) is trying to predict who will make a purchase，they can easily find data on customers who have purchased from them (positive data)，but it is basically impossible to obtain data on customers who have never purchased from them(negative data)，since they do not have access to their competitors' data.
According to lead author Takashi Ishida from RIKEN AIP，“Previous classification methods could not cope with the situation where negative data were not available，but we have made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users.Using our new_method，we can let computers learn a classifier only from positive data equipped with confidence.”
According to Ishida，“This discovery could expand the range of applications where classification technology can be used.Even in fields where machine learning has been actively used，our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints(限制)．In the near future，we hope to put our technology to use in various research fields，such as natural language processing，computer vision，robotics，and bioinformatics.”
【语篇解读】 分类对我们的日常生活至关重要。然而在分类技术机器学习过程中，分类既需要积极的数据，也需要消极的数据；而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器学习只识别积极的数据。
5．How can the computer distinguish the positive data from the negative data?
A．By learning the classification boundary.
B．By updating the data collected regularly.
C．By separating happy faces and sad ones.
D．By introducing classification technology.
A [细节理解题。根据第一段最后一句“Once a classification boundary is learned，the computer can determine whether certain data are positive or negative”可知，一旦学习了分类边界，计算机就可以确定某些数据是积极的还是消极的，由此可知，计算机是通过学习分类边界来区分积极数据和消极数据的。]
6．Why is the example mentioned in Paragraph 2?
A．To prove how important the positive data are.
B．To confirm that data on customers are complete.
C．To argue that retailers get their competitors' data.
D．To explain why negative data are hard to acquire.
D [细节理解题。根据文章的第二段，尤其是第一句“However，the difficulty with this technology is that it requires both positive and negative data for the learning process，and negative data are not available in many cases”可知，在学习过程中，它既需要积极的数据，也需要消极的数据，而消极的数据在很多情况下是很难获得的，进而后面举例说明解释了为什么消极的数据很难获得。]
7．What do the underlined words“new method”in Paragraph 3 refer to?
A．Analyzing buying intention.
B．Building a confidence score.
C．Assessing the active rate of app users.
D．Equipping the computer with confidence.
B [推理判断题。根据文章的第三段，尤其是画线词组前一句中的“but we have made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users”可推知，画线词组所在句表示使用这种建立信心指数的新方法，我们就可以让电脑只用积极的数据来学习，故画线词组是指建立信心指数。]
8．What can be a suitable title for the text?
A．The History of Classification Technology
B．Smarter AI: Machine Learning Without Negative Data
C．Bigger Data: Computers Assisting Language Processing
D．The Comparison between Positive Data and Negative Data
B [标题归纳题。通读全文可知，分类对我们的日常生活至关重要。然而在分类技术机器学习过程中，分类既需要积极的数据，也需要消极的数据，而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器学习只识别积极的数据。]

(2019·郑州一中入学摸底测试)Running is often tiring and a lot of hard work，but nothing beats the feeling you get after finishing a long workout around the track.
But while it's long been believed that endorphins(内啡肽)—chemicals in the body that cause happiness—are behind the socalled “runner's high”，a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities，a group of chemicals called endocannabinoids(内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory，the scientists turned to mice.
Both mice and humans release high levels of endorphins and endocannabinoids after exercise，along with many other chemicals.After exercising on running wheels，the mice seemed happy and relaxed and displayed no signs of anxiety.
But after being given a drug to block their endorphins they changed.However，when their endocannabinoids were block with a different drug，the runner's high symptoms seemed to fade.
“The longheld notion of endorphins being responsible for the runner's high is false.Endorphins are effective pain relievers，but only when it comes to the pain in your body and muscles you feel after working out，” Patrick Lucas Austin wrote on a science blog.
Similar studies are yet to be carried out on humans，but it's already well known that exercise is a highly effective way to get rid of stress or anxiety.
The UK's National Health Service even prescribes(开药方)exercise for patients who are suffering from depression.
“Being depressed can leave you feeling low in energy，which might put you off being more active.Regular exercise can boost your mood if you have depression，and it's especially useful for people with mild to moderate(中等的) depression，” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout，even if we don't fully understand where it comes from.At least if we're feeling down，we know that all we have to do is put on our running shoes.
【语篇解读】 本文主要探究了影响运动者情绪高涨的因素。
1．What did scientists from German universities recently discover?
A．Working out is a highly effective way to treat depression.
B．The runner's high could be caused by endocannabinoids.
C．Endorphins may contribute to one's high spirits after running.
D．The level of endorphins and endocannabinoids could affect one's mood.
B [细节理解题。根据第三段“According to a recent study published by a group of scientists from several German universities，a group of chemicals called endocannabinoids(内源性大麻素) may actually be responsible for this familiar great feeling”可知，德国一些大学的科学家们最近发现了跑步后的快感是由内源性大麻素引起的，故选B。]
2．The scientists gave mice drugs in their experiment to ________.
A．find what reduces the runner's high symptoms
B．see the specific symptoms of the runner's high
C．identify what is responsible for the runner's high
D．test what influences the level of endocannabinoids released
C [推理判断题。根据对第二段和第三段的整体理解，并结合第四段“To test this theory，the scientists turned to mice”可推知，科学家们拿老鼠做实验是为了确定究竟是哪种物质会引起跑步者的情绪高涨，故选C。]
3．The underlined word “notion” in Paragraph 7 has the closest meaning to ________.
A．effect B．goal
C．question D．belief
D [词义猜测题。根据对全文内容的理解可知，该词所在句子与第二段“But while it's long been believed that endorphins(内啡肽)—chemicals in the body that cause happiness—are behind the socalled ‘runner's high’， a study suggested that there may be more to this phenomenon than we previously knew”呼应，并结合本句结构可推知，此处notion与believed相呼应，故选D。]
4．According to the UK's National Health Service，regular workouts ________.
A．are the best way to treat depression
B．can help ease depression symptoms
C．only work for those with serious depression
D．can help people completely recover from depression
B [细节理解题。根据倒数第三、四段和倒数第二段第二句“Regular exercise can boost your mood if you have depression，and it's especially useful for people with mild to moderate(中等的)depression”可知，常规锻炼有利于情绪好转，缓解抑郁症状，故选B。]

(2019·昆明市摸底调研)Nine months ago，I was packing my daughter's backpack with new school supplies，wondering how I was going to send her off to kindergarten.I stood on the playground，tears pouring down my face because I wasn't ready for this first day of kindergarten—but she was ready.Today I will be standing on the playground，once again with tears，because this precious time went by too quickly.This week I realized that I never told you “thank you”．I don't know how to express a mother's thanks in the way a teacher deserves.
We first met you at the open house the week before school started and I immediately knew you would be the type of teacher we would appreciate forever. While the students lined up for the day，you touched each one on the shoulder as you greeted them.If a student was having a tough morning，you quietly held his hand and walked him into the school.
I got to know you as I volunteered in the lunch room.You made sure your students were all ready for lunch before you went on your own lunch break.You kept track of their big things and small things，because as a veteran kindergarten teacher，you know that the small things are the big things.I loved the way you made each student feel special.You helped them fall in love with school，which is so important at the start.
To all of the teachers in the world who are like you，I wish you knew how grateful parents are for you.We adore you，respect you，and appreciate you.We don't tell you enough—we probably don't tell you ever.I wish we could take you with us to the next 12 grades.

(2019·陕西省部分学校摸底检测)Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic.
The experts believe the machine should be able to collect half of the detritus in the patch—about 40,000 metric tons—within five years.In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine，creating the largest floating barrier ever made.
The system，originally dreamt up by Mr.Slat，will be shipped out this summer to the Great Pacific Garbage Patch，between Hawaii and California，which contains estimated 1.8 trillion pieces of plastic.It will be the first ever attempt to tackle the patch since it was discovered in 1997.
Mr.Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea.“There were more bags than fish down there，” he recalls.Two years later he came up with a solution，quit university after six months and set up The Ocean Cleanup as a company.Mr.Slat says the first plastic to arrive on shore will be a major milestone.“We as humanity created this problem，so I think it's also our responsibility to help solve it，” he says.
The Great Pacific Garbage Patch(GPGP) covers an area of 1.6 million square kilometers and contains at least 79,000 tons of plastic，research found last month. Most of it is made up of “ghost gear” — parts of abandoned and lost fishing gear，such as nets and ropes—often from illegal fishing vessels.
Ghost gear kills more than 100,000 whales，dolphins and seals each year，according to scientific surveys.Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic.Creatures eat plastic discarded in the sea thinking it's food but then starve to death because they are not feeding properly.Others are trapped and die of starvation or are strangled or suffocated by ghost gear.
【语篇解读】 本文是一篇说明文，主要介绍了世界首个海洋垃圾清扫机的发明。
1．What does the underlined word in the second paragraph probably mean?
A．Waste. B．Ocean.
C．System. D．Machine.

2．Which one makes up most of the garbage in Pacific from the passage?
A．Fishing vessels.
B．Dolphins and seals.
C．Giant tubes.
D．Abandoned fishing gear.
D [细节理解题。根据第五段最后一句“Most of it is made up of ‘ghost gear’—parts of abandoned and lost fishing gear，such as nets and ropes—often from illegal fishing vessels”可知，太平洋里的大部分垃圾是由废弃的钓鱼用具组成的。]
3．Why do some creatures in The Great Pacific Garbage Patch die of starvation?
A．Because they are killed by ghost gear.
B．Because they are suffocated by ghost gear.
C．Because they don't like eating plastic.
D．Because they are not feeding properly.
D [细节理解题。根据最后一段倒数第二句中的“but then starve to death because they are not feeding properly”可知，大太平洋垃圾带的一些生物死于饥饿是因为它们不能真正地进食。]

(2019·合肥市第二次教学质量检测)Classifying things is critical for our daily lives.For example，we have to detect spam mail(垃圾邮件)，false political news. When we use AI，such tasks are based on “classification technology” in machine learning—having the computer learn，using the boundary separating positive and negative data.For example，“positive” data would be photos including a happy face，and “negative” data photos that include a sad face.Once a classification boundary is learned，the computer can determine whether certain data are positive or negative.
However，the difficulty with this technology is that it requires both positive and negative data for the learning process，and negative data are not available in many cases.For instance，when a retailer(零售商) is trying to predict who will make a purchase，they can easily find data on customers who have purchased from them (positive data)，but it is basically impossible to obtain data on customers who have never purchased from them(negative data)，since they do not have access to their competitors' data.
According to lead author Takashi Ishida from RIKEN AIP，“Previous classification methods could not cope with the situation where negative data were not available，but we have made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users.Using our new_method，we can let computers learn a classifier only from positive data equipped with confidence.”
According to Ishida，“This discovery could expand the range of applications where classification technology can be used.Even in fields where machine learning has been actively used，our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints(限制)．In the near future，we hope to put our technology to use in various research fields，such as natural language processing，computer vision，robotics，and bioinformatics.”
【语篇解读】 分类对我们的日常生活至关重要。然而在分类技术机器学习过程中，分类既需要积极的数据，也需要消极的数据；而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器学习只识别积极的数据。
5．How can the computer distinguish the positive data from the negative data?
A．By learning the classification boundary.
B．By updating the data collected regularly.
C．By separating happy faces and sad ones.
D．By introducing classification technology.
A [细节理解题。根据第一段最后一句“Once a classification boundary is learned，the computer can determine whether certain data are positive or negative”可知，一旦学习了分类边界，计算机就可以确定某些数据是积极的还是消极的，由此可知，计算机是通过学习分类边界来区分积极数据和消极数据的。]
6．Why is the example mentioned in Paragraph 2?
A．To prove how important the positive data are.
B．To confirm that data on customers are complete.
C．To argue that retailers get their competitors' data.
D．To explain why negative data are hard to acquire.
D [细节理解题。根据文章的第二段，尤其是第一句“However，the difficulty with this technology is that it requires both positive and negative data for the learning process，and negative data are not available in many cases”可知，在学习过程中，它既需要积极的数据，也需要消极的数据，而消极的数据在很多情况下是很难获得的，进而后面举例说明解释了为什么消极的数据很难获得。]
7．What do the underlined words“new method”in Paragraph 3 refer to?
A．Analyzing buying intention.
B．Building a confidence score.
C．Assessing the active rate of app users.
D．Equipping the computer with confidence.
B [推理判断题。根据文章的第三段，尤其是画线词组前一句中的“but we have made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users”可推知，画线词组所在句表示使用这种建立信心指数的新方法，我们就可以让电脑只用积极的数据来学习，故画线词组是指建立信心指数。]
8．What can be a suitable title for the text?
A．The History of Classification Technology
B．Smarter AI: Machine Learning Without Negative Data
C．Bigger Data: Computers Assisting Language Processing
D．The Comparison between Positive Data and Negative Data
B [标题归纳题。通读全文可知，分类对我们的日常生活至关重要。然而在分类技术机器学习过程中，分类既需要积极的数据，也需要消极的数据，而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器学习只识别积极的数据。]

(2019·郑州一中入学摸底测试)Running is often tiring and a lot of hard work，but nothing beats the feeling you get after finishing a long workout around the track.
But while it's long been believed that endorphins(内啡肽)—chemicals in the body that cause happiness—are behind the socalled “runner's high”，a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities，a group of chemicals called endocannabinoids(内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory，the scientists turned to mice.
Both mice and humans release high levels of endorphins and endocannabinoids after exercise，along with many other chemicals.After exercising on running wheels，the mice seemed happy and relaxed and displayed no signs of anxiety.
But after being given a drug to block their endorphins they changed.However，when their endocannabinoids were block with a different drug，the runner's high symptoms seemed to fade.
“The longheld notion of endorphins being responsible for the runner's high is false.Endorphins are effective pain relievers，but only when it comes to the pain in your body and muscles you feel after working out，” Patrick Lucas Austin wrote on a science blog.
Similar studies are yet to be carried out on humans，but it's already well known that exercise is a highly effective way to get rid of stress or anxiety.
The UK's National Health Service even prescribes(开药方)exercise for patients who are suffering from depression.
“Being depressed can leave you feeling low in energy，which might put you off being more active.Regular exercise can boost your mood if you have depression，and it's especially useful for people with mild to moderate(中等的) depression，” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout，even if we don't fully understand where it comes from.At least if we're feeling down，we know that all we have to do is put on our running shoes.
【语篇解读】 本文主要探究了影响运动者情绪高涨的因素。
1．What did scientists from German universities recently discover?
A．Working out is a highly effective way to treat depression.
B．The runner's high could be caused by endocannabinoids.
C．Endorphins may contribute to one's high spirits after running.
D．The level of endorphins and endocannabinoids could affect one's mood.
B [细节理解题。根据第三段“According to a recent study published by a group of scientists from several German universities，a group of chemicals called endocannabinoids(内源性大麻素) may actually be responsible for this familiar great feeling”可知，德国一些大学的科学家们最近发现了跑步后的快感是由内源性大麻素引起的，故选B。]
2．The scientists gave mice drugs in their experiment to ________.
A．find what reduces the runner's high symptoms
B．see the specific symptoms of the runner's high
C．identify what is responsible for the runner's high
D．test what influences the level of endocannabinoids released
C [推理判断题。根据对第二段和第三段的整体理解，并结合第四段“To test this theory，the scientists turned to mice”可推知，科学家们拿老鼠做实验是为了确定究竟是哪种物质会引起跑步者的情绪高涨，故选C。]
3．The underlined word “notion” in Paragraph 7 has the closest meaning to ________.
A．effect B．goal
C．question D．belief
D [词义猜测题。根据对全文内容的理解可知，该词所在句子与第二段“But while it's long been believed that endorphins(内啡肽)—chemicals in the body that cause happiness—are behind the socalled ‘runner's high’， a study suggested that there may be more to this phenomenon than we previously knew”呼应，并结合本句结构可推知，此处notion与believed相呼应，故选D。]
4．According to the UK's National Health Service，regular workouts ________.
A．are the best way to treat depression
B．can help ease depression symptoms
C．only work for those with serious depression
D．can help people completely recover from depression

(2019·昆明市摸底调研)Nine months ago，I was packing my daughter's backpack with new school supplies，wondering how I was going to send her off to kindergarten.I stood on the playground，tears pouring down my face because I wasn't ready for this first day of kindergarten—but she was ready.Today I will be standing on the playground，once again with tears，because this precious time went by too quickly.This week I realized that I never told you “thank you”．I don't know how to express a mother's thanks in the way a teacher deserves.
We first met you at the open house the week before school started and I immediately knew you would be the type of teacher we would appreciate forever. While the students lined up for the day，you touched each one on the shoulder as you greeted them.If a student was having a tough morning，you quietly held his hand and walked him into the school.
I got to know you as I volunteered in the lunch room.You made sure your students were all ready for lunch before you went on your own lunch break.You kept track of their big things and small things，because as a veteran kindergarten teacher，you know that the small things are the big things.I loved the way you made each student feel special.You helped them fall in love with school，which is so important at the start.
To all of the teachers in the world who are like you，I wish you knew how grateful parents are for you.We adore you，respect you，and appreciate you.We don't tell you enough—we probably don't tell you ever.I wish we could take you with us to the next 12 grades.

【语篇解读】 本文是一篇说明文，主要介绍了VAR在足球比赛中的应用，以及由此而引起的一些争议。
1．B [上文是说多年来，VAR技术已经应用于美国的运动中，现在它已经完全与全球的足球比赛结合起来，而且在2018年的世界杯中首次亮相，而空后是说它实际是一个通过观看视频重放来审查主裁判的某些决定的团队，故B项“VAR代表着视频助理裁判”符合语境，衔接上下文，故选B。]
2．E [根据空后一句“They will communicate...serious missed incidents”可知，他们会为清晰而明显的错误或错过的事件和裁判沟通，E项“他们在整场比赛中持续检查错误”符合语境，故选E。]
3．D [根据空后的“the referee would start an official review”可知，裁判将启动一个官方的审查，与D项中的“reviewable”呼应，故选D。]
4．F [根据空处所在位置以及该段叙述的球迷对VAR在比赛中应用的一些看法可推知，F项“视频技术的应用在足球观看者之中是一个热点话题”概括了本段的内容，故选F。]
5．G [根据空前的“angry players crowd around a referee following a controversial decision”可知，此处描述了一个球赛中的场景，G项中的“such scenes”与之呼应，故选G。]

【语篇解读】 本文主要介绍了一项体育运动——Walking Football。
1．growing [考查形容词。分析句子结构可知，空处与and之前的形容词popular是并列关系，共同修饰其后的名词format，故应填growing“增长的”。]
2．definitely [考查副词。分析句子结构可知，空处修饰副词just，故应用副词definitely。]
3．requires [考查动词的时态。分析句子结构可知，and前后是并列的成分，此处应与carries形式相同，故填requires。]
4．with [考查介词。分析句子结构可知，此处是with的复合结构，即with＋名词＋介词短语的形式，在句子中作状语，与下文中的“With less stress on the body”结构相呼应。]

7．or [考查连词。根据语境可知，此处表示“或者”，故用表示选择关系的连词or。]
8．have had [考查动词的时态。根据本句中的Since可知，主句应用现在完成时，表示过去发生的动作对现在造成的影响，即have had。]
9．weekly [考查形容词。根据空前的冠词a和空后的名词basis可知，此处应用形容词weekly。]
