【分析】短文主要讲述了作者和他的宠物狗之间的故事。
11．句意：多年来，朋友们警告我，让心爱的宠物离开是他们做过的最困难的决定。空处的词在定冠词the之后，应是名词；根据空后“the most difficult one they had ever made.”可知，空处应是decision“决定”，名词。故选E。
12．句意：那时，我会点头同意，继续我的一天。根据下句“As my dog got older, however, this reality neared for me.”可知，应是会点头同意朋友的观点。故空处应是agree“同意”，动词；空处的词是和nod并列的词，用于would之后，应用动词原形。故选B。
13．句意：狗的需求很简单：它必须和孩子们一起去一所房子，在那里它将是唯一的宠物，并被忠实地爱着。根据下文“It must go to a house with kids, where it will be the only pet and loved….”可推知，应是狗的需求很简单，故空处应是simple“简单的”，形容词。故选A。
14．句意：狗的需求很简单：它必须和孩子们一起去一所房子，在那里它将是唯一的宠物，并被忠实地爱着。根据句意，空处的词是修饰动词，应用副词；结合选项可知，空处应是faithfully“忠实地”，副词。故选D。
15．句意：她加入了一个活跃的家庭，她的生活瞬间改变了。根据句子结构可知，空处是谓语动词；根据后句“She may have wanted to go home during her first like, but she soon became an adventure buddy.”的语境可知，应是她的生活瞬间改变了，故空处应是changed“改变”，动词change的过去式。故选D。
16．句意：Coco和我们一起到处走。空处的词在动词went之后，应是副词；根据下文“When friends teased（取笑）us that we treated Coco as a human child, we’d reply that she was sometimes the best-behaved child.”的语境可知，空处应是everywhere“到处”，副词。故选A。
17．句意：那个最后的周末对我们所有人来说都是如此艰难，我们试图感谢这只可爱的狗15年的陪伴和爱。根据文中“She…the world where she had lived: loving us and being loved right back.”可知，应是最后的一个周末，故空处应是last“最后的”，形容词。故填C。
18．句意：她离开了她曾经生活过的世界：爱过我们，被爱过。根据前句“That…weekend was so hard on all of us, trying to thank this sweet dog for 15 years of companionship and love.”可知，应是她离开了她曾经生活过的世界，故空处应是left“离开”，动词leave的过去式。故选E。

三、用所给单词的正确形式填空
19．She was praised for （save）the life of the child.
【答案】saving

21．The noisy music made the old couple feel .(happy)
【答案】unhappy

【答案】valuable
【详解】句意：你愿意和我一起去那个新的美术馆吗？我听说里面有很多有价值的古老的画。value价值，是一个名词。根据句子结构可知，这里应填形容词形式，修饰后面的名词paintings，故应填valuable，有价值的。

Her doctor says that she will make a full recovery in a day or two.
Jennifer’s classmates hope to see her back at school soon.

Jennifer’s case is a reminder of the 41 of the unhealthy weight-loss habits that have become common among teenagers of both sexes. In a society where being thin is often seen as being beautiful, teenagers sometimes turn to extreme methods to slim down quickly. According to a recent survey of senior high school students’ lifestyles, almost one fifth of teenagers regularly skip meals, one in ten over-exercise and four per cent even take weight-loss medicine. Health experts are 42 these figures. They are increasing their efforts to educate teenagers about the side effects of losing weight too quickly. They have also warned them against using such extreme methods.

She pointed out that it is important to have a healthy balanced diet since teenagers are still growing and their bodies need a lot of nutrition to function well. If they do not take in enough food, they may feel weak and get ill easily. She added, “ 44 , they should keep regular hours and get plenty of exercise to stay energetic and fit.

七、短文首字母填空
Fill in the blanks with proper words（在短文的空格内填入适当的词，使其内容通顺，每空格限填一词，首字母已给）
Many people are familiar with the story of the Titanic because of the popular film of the same name. The ship hit an iceberg(冰山) and sank on its only voyage(航行) in 1912. It was one of the great d 45 of the 20th century. We can never be completely sure of the numbers, but people agree that about 2,200 people were on the ship at that time. However, there were not e 46 lifeboats for everyone, and only around 700 people survived. Of course, the film Titanic was very successful, yet we should always find out what is fiction(虚构) and what is reality.
We should realize that most of the action in the film never a 47 happened. For example, the story of Jack and Rose, the young man and woman who fall in love, is complete fiction. They are not real people and their story may not be true at all.
At the same time, some of the c 48 in the film were based on real people, but the film changes the truth about them. For example, Molly Brown was a real p 49 on the ship. In the film, Brown is on a lifeboat and asks the lifeboat captain if they should go back to look for people in the water. When the lifeboat captain refuses to go back, she says nothing. In real life, Molly Brown fought with the lifeboat captain, turned the lifeboat around, and tried her best to s 50 others. Although she is quiet in the film, she was really a hero to many people in real life.
A 51 real-life person in the film is First Officer William Murdoch. The film shows that he shot other people before he killed himself. In real life, however, many people agree that he died because he tried to get a lifeboat into the water so that more people could have a chance to survive.


【答案】45．(d)isasters 46．(e)nough 47．(a)ctually 48．(c)ontents 49．(p)erson 50．(s)ave 51．(A)nother

【导语】本文主要讲述了曾经轰动一世的泰坦尼克的故事，改编成电影之后其中的部分细节是由真实人物改编的，本文详细地介绍了其中两位真实的人物。
45．句意：这是20世纪最大的灾难之一。根据“We can never be completely sure of the numbers, but people agree that about 2,200 people were on the ship at that time”及首字母可知，这是一个巨大的灾难，disaster“灾难”，one of+复数名词，故填(d)isasters。
46．句意：然而，没有足够的救生艇来容纳每个人，只有大约700人幸存下来。根据“and only around 700 people survived”可知，没有足够的救生艇，所以只有大约700人幸存下来，enough“足够的”，故填(e)nough。
47．句意：我们应该意识到，电影中的大部分内容都没有真正发生过。此空修饰动词happened，应填副词。结合“is complete fiction”可知，大部分内容都没有真正地发生过，actually“真实地”，故填(a)ctually。
48．句意：同时，电影中的一些内容是基于真实的人，但电影改变了他们的真相。根据“some of the …in the film”及首字母可知，此处指电影中的一些内容，content“内容”，根据some可知，此空应填复数形式，故填(c)ontents。
49．句意：例如，莫莉·布朗是船上的一个真实的人物。根据“real-life person in the film is First Officer William Murdoch”可知，她是一个真实存在的人，person“人”，故填(p)erson。
50．句意：尽她最大的努力去救别人。根据“Molly Brown fought with the lifeboat captain, turned the lifeboat around”可知，和救生艇船长搏斗，把救生艇调转了方向，救了其他人，save“拯救”，动词不定式符号to后接动词原形，故填(s)ave。
51．句意：影片中的另一个真实人物是大副威廉·默多克。根据“For example, Molly Brown was a real …on the ship”可知，此处提到另一个真实的人物，another“另一个”，故填(A)nother。

八、阅读回答问题
阅读短文，根据短文内容用英语回答问题，每题答案不超过5个单词。
We always think that it is OK to leave our plants unattended (无人照料的) during our vacation since we believe that they will survive just fine. After all, plants won’t make noise like pets, so they must be okay. Well, a recent study has found a different answer. A group of scientists from the Tel Aviv University have discovered that some plants scream in a high frequency when they “think” they are in danger.
Scientists did the research on tomato plants by cutting their stems and depriving (剥夺) them of water. A microphone was put 10 cm away from the plants to collect their sound. When the scientists started cutting the stems, the plants began screaming between 20 and 100 kilohertz, which the scientists believe was to warn other plants nearby. When the tomato plants’ stems were cut, 25 ultrasonic sounds were recorded in an hour. When they did not receive enough water, the microphone got even more: 35 times in an hour.
For the first time in history, scientists seem to have evidence that, like animals, plants can make noise in face of difficulty. “People have always believed that plants are silent,” one of the scientists said. “But the truth is that their voices are so high-pitched (高音调的) that we just can’t hear them.”
52．What did scientists do the research on?

53．When would plants make noise according to the passage?

54．What did the scientists put near the plants to collect sound?

55．Why did the plants scream according to the scientists?

56．How do you feel after knowing plants can make noise?


【答案】52．Tomato plants. 53．In face of difficulty. 54．A microphone. 55．Because they are in danger. 56．That sounds interesting.

【导语】本文主要是介绍人们一直认为植物不会发出声音，但最近的研究表明：植物遇到危险时，同样会发出声音，只是声音太高，人类听不到。这听起来非常有趣。
52．根据“Scientists did the research on tomato plants by cutting their stems and depriving (剥夺) them of water.”可知科学家对西红柿进行了研究，故填Tomato plants.
53．根据“For the first time in history, scientists seem to have evidence that, like animals, plants can make noise in face of difficulty.”可知当植物遇到困难时，它们会发出噪音，故填In face of difficulty.
54．根据“A microphone was put 10 cm away from the plants to collect their sound.”可知科学家把传声器放在植物旁边去收集声音，故填A microphone.
55．根据“A group of scientists from the Tel Aviv University have discovered that some plants scream in a high frequency when they “think” they are in danger.”可知当植物认为自己处在危险中时，它们会尖叫，故填Because they are in danger.
56．开放性答案。根据“People have always believed that plants are silent”可知人们一直认为植物不会发出声音，现在知道植物也会发出声音后，我感觉很有趣，故填That sounds interesting.

九、书信作文

【答案】例文：
Dear Sir,
I am writing to you to ask for keeping a pet dog. Dogs are the best friends of human beings. They are smart and loyal to their masters. Since I am the only child in my family, I want to keep a dog as my companion.
If I have a pet dog, I will take him out for a walk every day. I will help him have a bath every night and buy him the dog food he likes. I will also take him regularly for physical check-ups and vaccinations. I’m sure we’ll have a good time together.
I’m looking forward to your approval.
Yours,
Li Hua
