Unit 2 Wildlife Protection B卷
一、阅读理解
1. I suddenly heard an elephant crying as though frightened. Looking down, I immediately recognized that something was wrong, and ran down to the edge of the near bank. There I saw Ma Shwe with her three-month-old calf struggling in the fast-rising water, and it was a life-and-death struggle. Her calf was floating and screaming with fear. Ma Shwe was as near to the far bank as she could get, holding her whole body against the rushing water, and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away. There was a sudden rise in the water and the calf was washed clean over the mother's body and was gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk(象鼻) against the rocky bank. Then with a huge effort, she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment, she went back into the river. If she were carried down, it would be certain death. I knew, as well as she did, that there was one spot(地点) where she could get to the bank, but it was on the other side from where she had put her calf. While I was wondering what I could do next, I heard the sound of a mother's love. Ma Shwe had crossed the river and got to the bank and was making her way back as fast as she could, roaring(吼叫) all the time, but to her calf it was music.
(1). The moment the author got down to the river bank he saw _______.
A. the calf was about to fall into the river
B. Ma Shwe was placing the calf on the rock
C. the calf was washed away by the rising water
D. Ma Shwe was holding the calf against the rushing water
(2). How did Ma Shwe manage to save her calf from the fast-flowing water
A. By putting it on a safe spot. B. By pressing it against her body.
C. By taking it away with her. D. By carrying it on her back.
(3). How did the calf feel about the mother elephant's roaring
A. It was a musical note. B. It was a sign of danger.
C. It was a call for help. D. It was a great comfort.
2. After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations—major food sources (来源) for the wolf—grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park's red foxes, and completely drove away the park's beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
1.What is the text mainly about
A.Wildlife research in the United States.
B.Plant diversity in the Yellowstone area.
C.The conflict between farmers and gray wolves.
D.The reintroduction of wolves to Yellowstone Park.
2.What does the underlined word "displaced" in paragraph 2 mean
A.Tested. B.Separated. C.Forced out. D.Tracked down.
3.What did the disappearance of gray wolves bring about
A.Damage to local ecology. B.A decline in the park's income.
C.Preservation of vegetation. D.An increase in the variety of animals.
4.What is the author's attitude towards the Yellowstone wolf project
A.Doubtful. B.Positive. C.Disapproving. D.Uncaring.
3. One animal which is still alive, but has almost disappeared from the world, is the Chinese river dolphin or baiji.
The baiji is a beautiful animal with agraceful body and a long nose. It is blue-grey with a white underside, weighs between 100 and 160 kilogrammes, and can grow up to eight feet long. It lives in the middle and lower parts of the Yangtze River. Most dolphins live in the sea so the baiji is very unusual. It is one of only five kinds of river dolphins in the world.
In the past, the Yangtze River was home to many thousands of baiji. A book written during the Han Dynasty,22 centuries ago, tells of the river being full of the beautiful creatures. At that time, there were many stories about the baiji. One story said that the dolphin was really a beautiful princess who had drowned in the river. Another said it was a kind of horse that could gallop (急速行进) across water, carrying God on its back.
Sadly, the situation today is very different. Many millions of people live in the Yangtze River Basin and the river is busy, noisy and polluted. The baiji is almost blind and moves around using sounds. With so many boats and people using the river, the animals cannot find their way around. They are unable to find food, or find each other. Year by year, the number of baiji in the river becomes smaller and smaller.
A lot of work is being done to help the baiji. One section of the river has been made into a kind of nature park, where the baiji can be safe. Fishermen work together with scientists and tell them when they see a baiji, or if they find an injured one. Injured animals are taken to a research center and nursed back to be healthy. However, in spite of these measures, scientists estimate(估计) that the mumber of the baiji still alive in the river may be less than 100. If things continue as they are, the lovely creature will disappear in the next 25 years.
1.Which description about the baiji is WRONG
A.It has already died out from the world.
B.It is blue-grey with a white underside.
C.It lives in the middle and lower parts of the Yangtze River.
D.It is one of only 5 kinds of river dolphins in the world.
2.The reasons why the baiji is disappearing are the following EXCEPT _____.
A.many millions of people live in the Yangtze River Basin, making there noisy and polluted
B.the baiji is blind because of the pollution and can't find the way around
C.the boats and people are noisy, making the animals cannot find their way around by sounds
D.they are unable to find food or find each other by sounds since the river is noisy
3.Which of the following is the correct way to save the baiji
A.Catch the baiji and take them to the research center.
B.Make the whole Yangtze River a nature park for the baiji to live in.
C.Make one section of the river a nature park where the baiji can be safe.
D.Ask many people to come to the river to help the baiji
4.What can we learn from the passage
A.People can take some measures to save the animals dying out.
B.The animals dying out are being hunted by human beings.
C.People like to live in the Yangtze River Basin with animals swimming in the river.
D.There are more baiji living in a nature park now.
4. How does an ecosystem(生态系统) work What makes the populations of different species the way they are Why are there so many flies and so few wolves To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats.
With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator(掠食动物) always eats huge numbers of a single prey(猎物), the two species are strongly linked; when a predator lives on various species, they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.
Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species—including species they did not directly attack.
And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves. These actions have greatly affected the ecological balance.
Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists say because once ecosystems pass their tipping point(临界点), it is remarkably difficult for them to return.
1. What have scientists discovered with the help of mathematical models of food webs
A. The living habits of species in food webs.
B. The rules governing food webs of the ecosystems.
C. The approaches to studying the species in the ecosystems.
D. The differences between weak and strong links in food webs.
2. A strong link is found between two species when a predator ________.
A. has a wide food choice
B. can easily find new prey
C. sticks to one prey species
D. can quickly move to another place
3. What will happen if the populations of top predators in a food web greatly decline
A. The prey species they directly attack will die out.
B. The species they indirectly attack will turn into top predators.
C. The living environment of other species will remain unchanged.
D. The populations of other species will experience unexpected changes.
4. How does an early-warning system help us maintain the ecological balance
A. By getting illegal practices under control.
B. By stopping us from killing large predators.
C. By bringing the broken-down ecosystems back to normal.
D. By signaling the urgent need for taking preventive action.

5. Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two metres long. The dogfish shark, however, is less than twenty centimetres in length. A shark has an extremely good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. ①_______ Sharks eat fish, other sharks, and plants that live in the ocean.
Sharks grow slowly. About forty percent of all sharks lay eggs. ②_______ Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, overfishing of sharks is of special danger to the future of the animal.
Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too great. ③_______
People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.
Collectors pay thousands of dollars for the jaws of a shark. ④_______ The skin of a shark can be used like leather.
In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth. ⑤_______

五、读后续写
8.阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
I took a job as a receptionist for a veterinarian(兽医) almost five decades ago. As an enthusiastic animal lover, I accepted the position on condition that I wouldn't have to assist with any wounded animals. I couldn't bear to see any creature in pain. At the end of my first week, we were closing the office for the day when a young man ran up to us holding a severely injured Doberman puppy in his arms and begging us to save his life. The four-month-old pup had been hit by a car.
The doctor and I ran back into the operating room. The only place the skin was still attached to this poor little animal's body was around one shoulder. The vet worked tirelessly for what seemed like hours, stitching(缝合) him back together again. That was the easy part. The puppy had broken multiple bones, including his spine (脊柱). Even if he survived the next few days, we were quite sure he would never walk again.
That day forever changed my life. The veterinarian guided me, and I became his assistant in all things. One of my first jobs was to give that Doberman puppy daily physical care. I remembered moving his tiny legs to try to keep his muscles from withering (萎缩). Weeks went by until one day, I felt this little fighter push back ever so slightly. And he continued to push back till he could finally use his legs. He recovered.
A year later, I walked into the clinic's waiting room and saw a huge Doberman who had been standing quietly with his owner on the opposite side of the room. I called the name of the next client.
注意:续写词数应为150左右。
Suddenly, the huge Doberman broke loose and rushed toward me. ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
I went on to be a vet technician for 14 years, and since retirement, I've volunteered at a no-kill animal shelter. ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

参考答案
1.答案：(1)-(3) DAD
解析：(1).细节理解题。根据文章第一段的"There I saw Ma Shwe with her three-month-old calf struggling in the fast-rising water, and it was a life-and-death struggle... holding her whole body against the rushing water..."可知，Ma Shwe尽可能地贴近河岸,抓住小象来对抗洪水。故选D项。
(2).细节理解题。根据文章第一段中对Ma Shwe营救小象的细节的描写可知，Ma Shwe是在寻找一个安全的地方。文章第二段第三句话"I knew, as well as she did, that there was one spot(地点) where she could get to the bank, but it was on the other side from where she had put her calf."再次说明她是通过把小象放到一个安全的地方来营救小象的。故选A项。
(3).推理判断题。根据文章对小象的描写可知，小象一直处于紧张、害怕的状态，直到象妈妈成功地救了自己并来到自己身边时，小象的害怕和紧张情绪才得以平复，所以象妈妈的吼叫也像是音乐一般成为对小象的一种抚慰。故选D项。
2.答案：1.D; 2.C; 3.A; 4.B
解析：1.主旨大意题。根据第一段第一句"... gray wolves were reintroduced to Yellowstone National Park. " 和最后一段第一句"The government spent nearly 30 years coming up with a plan to reintroduce the wolves. "可知,文章主要介绍了黄石国家公园的灰狼消失后产生的影响以及当地政府重新引入灰狼的计划。故选D项。
2.词义猜测题。根据第二段可知,在黄石国家公园,灰狼曾经随处可见,但是到了20世纪20年代,由于人类活动频繁,灰狼基本消失,它们迁徙到了加拿大的森林深处,那里很少有人类活动。因此可推测灰狼因为人类的发展被迫离开。force out意为"赶出去",与displace意思相近,故选C项。
3.细节理解题。根据第三段可知,灰狼的消失带来了很多意料之外的后果,鹿和麋鹿的数量激增,它们消耗了大量的植被,破坏了公园里植物的多样性同时丛林狼的数量也迅速增长, 造成赤狐数量的减少和河狸的消失。因此灰狼的消失破坏了当地的生态,故选A项。
4.推理判断题。由文章最后一段最后一句话中的a valuable experiment可推知,作者对黄石国家公园的灰狼回归计划持赞同的态度,故选B项。doubtful意为"怀疑的";positive意为 "赞同的";disapproving意为"不赞成的";uncaring意为"漠不关心的"。
3.答案：1.A; 2.B; 3.C; 4.A
解析： 1.细节理解题。由第一段中的...still alive, but has almost disappeared 可知,应选 A。
2.B 推理判断题。第四段讲述了baiji减少的原因:它们是一种靠声音辨别方向的动物,随着住在长江沿岸的人的增多,长江变得喧闹,它们就找不到方向,找不到食物和同伴了,所以数量逐渐减少。
3.C 推理判断题。baiji数量减少最重要的原因就是它们要依靠声音辨别方向,而人类活动把它们所需要的宁静破坏了,最好的办法自然就是还给它们原有的宁静环境——建一片自然公园,当然不可能将整个长江建成自然公园,所以是一部分, C对B错;只需把受伤的baiji带回研究中心治疗,不是把每条都抓回去,最适合它们的家还是长江,故A错;让许多人到长江只会加剧baiji灭亡而不是帮助它们,故D错。
4.A 推理判断题。根据全文内容推知人们可以采取措施来保护瀕临灭绝的动物。
4.答案：1-4 BCDD
解析：1.细节理解题。根据第二段第一句"With such models, scientists have found out some key principles operating in food webs."可知，应选B项。
2.推理判断题。根据第二段第句"When a predator(掠食动物) always eats huge numbers of a single prey(猎物), the two species are strongly linked..."可知，当一种掠食动物总是吃掉数量庞大的单一种类的猎物时，这两种动物有较强关联；结合下文可知，有较弱关联的两个物种，掠食动 物有广泛的食物选择、容易找到新的猎物，故排除A、B项。 D项在文中没有提及，也排除。故选C项。
3.细节理解题。根据第三段第二句"In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species—including species they did not directly attack."可知，若一个食物链顶层的掠食动物大规模减少， 其他物种的数量将会经历意想不到的改变。故选D项。
4.细节理解题。根据最后一段第二句"Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem bade from the borderline."可知，预警系统是通过发出需要采取预防行动的信号来帮助我们维护生态平衡。故本题选D项。
5.答案：1-5 DGBAE
解析：1.根据前面一句"It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals."可知鯊鱼灵敏的嗅觉可以使它们找到水里的血、体液以及动物产生的化学物质。这样的能力让它们迅速找到食物。故D项正确。
2.本句叙述鲨鱼的繁衍方式。根据前面一句"About forty percent of all sharks lay eggs."可知百分之四十的鲨鱼产卵。G项指其余的鲨鱼直接生出小鲨鱼。故G项正确。
3.根据前面一句"Their hunting activities mean that the numbers of other fish in ocean waters do not become too great."可知鲨鱼可以保持海洋的生态平衡，不让某些生物的数量太大。这间接地保护了海洋里的其他生物。故B项正确。
4.根据前一句"Collectors pay thousands of dollars for the jaws of a shark."和后一句"The skin of a shark can be used like leather."可知本段是在叙述鲨鱼各部位的价值，只有A项与这两句属于同类。故A项正确。
5.根据前面一句"Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth."可知某些鲨鱼已经面临着灭绝的危险。一旦某一区域内大量的鲨鱼被捕杀，该区域的鲨鱼就很难恢复到正常的数狱。故E项正确。
6.答案：1-5 DBACB 6-10 ABDDC 11-15 ADCDB

8.答案：
Suddenly, the huge Doberman broke loose and rushed toward me. I found myself pinned against the wall in amazement. To my surprise, the dog stood on his legs, his front paws on my shoulders, washing my face with joyful and abundant kisses! His owner came to me and told me that he was the dog we had saved one year ago. More than excited to see him again in such good health, I hugged him tightly, determined to become a good vet technician at that moment.
I went on to be a vet technician for 14 years, and since retirement, I've volunteered at a no-kill animal shelter. Being a vet technician and a volunteer at the no-kill animal shelter. I succeeded in saving more animals, which often made me think of the grateful huge Doberman. Although many years have passed, I still shed tears in amazement at the display of love and gratitude the dog had for me. All the dogs knew they had been rescued by me and they were grateful to me.
9.答案：
Dear Sir or Madam,
I'm writing to give some suggestions to protect the wildlife living in and around our city. As we know, many species of wildlife are in danger of extinction. This is because the environment that they are living in has been destroyed greatly.
With the development of cities, water and air are seriously polluted. Their living areas are becoming smaller and smaller. They not only have little to cat, but also can be killed by human beings. These species of wildlife are important part of our life. Personally, more measures should be taken to protect them from being hurt. Firstly, more laws must be made to stop people from cutting down trees. Secondly, all the factories must clean the waste water before it is poured into rivers or lakes. Thirdly, more reserves should be set up so that they can live safely.
I hope my suggestions are of much help.
Yours sincerely,

Considering that there was no better way, Mrs Smith took a piece of paper, and wrote the following words on it, "Give my dog half a pound of meat." Then she gave the paper to her dog and said gently, "Take this to the butcher(卖肉者), and he's going to give you your lunch today."
Holding the piece of paper in its mouth, the dog ran to the butcher's shop. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady's handwriting and pleasantly did as he was asked to. The dog was very happy, and ate the meat up immediately.
At midday, the dog came to the shop again. It gave the butcher a piece of paper again. After reading it, he gave it half a pound of meat once more.
The next day, the dog came again exactly at midday. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at the paper, and gave the dog its meat, for he had thought of the dog as one of his customers.
However, the dog came again at four o'clock. And the same thing happened once again. To the butcher's more surprise, it came for the third time at six o'clock, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, "This is a small dog. Why does Mrs Smith give it so much meat to eat today "
Looking at the piece of paper, he found that there were not any words on it!
(1).When Mrs Smith's dog was hungry, what did she give to the dog
A.Some chicken.

C.the butcher would give the meat to it whenever he saw it
D.Mrs Smith would pay for the meat it got from the butcher
2.Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.

3. I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley.
Trying to help injured, displaced or sick creatures can be heart breaking; survival is never certain. However, when it works, it is simply beautiful.
I got a rescue call from a woman in Muttontown. She had found a young owl (猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.
I examined the chick (雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but noluck. My next work was to construct a nest and anchor it in a tree.
The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.
Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.
A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all-LUNCH! The parents had done their duty and would probably continue to do so.
1. What is unavoidable in the author's rescue work according to paragraph 1
A.Efforts made in vain. B.Getting injured in his work.
C.Feeling uncertain about his future. D.Creatures forced out of their homes.
2.Why was the author called to Muttontown
A.To rescue a woman. B.To take care of a woman.
C.To look at a baby owl. D.To cure a young owl.
3.What made the chick calm down
A.A new nest. B.Some food. C.A recording. D.Its parents.
4.How would the author feel about the outcome of the event
A.It's unexpected. B.It's beautiful. C.It's humorous. D.It's discouraging.
4. Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care Because we need animals. And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers kill large numbers of hawks(鹰), the farmers' stores of corn and grain will be destroyed by mice. Why Because hawks eat mice. With no hawks to keep down their numbers, the mice multiplies quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
1.What is the best title for the passage
A.Save the Animals B.Useful Animals C.Laws for Animals D.Animals in Danger
2.Animals are important to us mainly because ________.

C.they keep the balance of nature D.they give us a lot of pleasure
3.Which of the following is NOT true
A.People care much about animals because we need them.
B.People must not kill any animal or plant.
C.Killing all mice may cause some new problems.
D.Once a certain kind of animal is gone forever, there will never be any more.
4.We can infer from the passage that _______.
A.people have known the importance of animal protection for a long time
B.animals play an important role in people's life
C.the number of hawks is on the decrease
D.many countries passed laws forbidding the killing of any animal

四、读后续写
7.阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。
In 2004, my husband, Joe and I worked in a design company in Arizona. One day, when we got back home after work, my ten-year-old daughter Becky, and Joe were united in their desire for a dog. As for me, I shared none of theirs. “But why,” they pleaded(恳求). “Because I don’t have time to take care of a dog.”
“But we’ll do it.” “Really You’re going to walk the dog Feed the dog Bathe the dog ” “Yes, yes, and yes.” “I don’t believe you.” “We will. We promise.”
They didn’t. They wanted to walk the cute dog that first day. From day two, neither of them thought to walk the dog. While I was slow to accept that I would be the one to keep track of her shots, to feed and clean her, Misty knew this on day one. As she looked up at the three new humans in her life, she calculated,“The medium one is the most reliable.”
Quickly, she and I developed something very similar to a Vulcan mind meld(心灵相通). She’d look at me with those sad brown eyes of hers, send her need, and then wait, trusting I would understand—which, strangely, I almost always did. In no time, she would extend across my stomach as I watched television, and snored on my home-office couch as I worked on my design.
Even so, part of me continued to reject walking duty. Joe and Becky had promised. “Not fair,” I said to myself as she and I walked. “Not fair,” I’d loudly remind anyone within earshot upon our return home.
In September, 2008, the Great Depression hit Arizona. With that, my husband and I were both laid off overnight. During the following six months, Joe and I hurriedly rushed here and there to seek a new job, doing anything and everything we could to request employment. Every part of my life changed; no part of my old routine remained. However, Misty still needed walking.

解析：(1).细节理解题。根据第二段中的"...Mrs Smith took a piece of paper, and wrote the following words on it... Then she gave the paper to her dog..."可知，史密斯夫人把一张写着一句话的纸给了她的狗，故选D项。
(2).细节理解题。根据第二段中的"Then she gave the paper to her dog and said gently..."中的 gently可知，史密斯夫人对她的小狗很友善，故选C项。
(3).推理判断题。根据第五段中的"...for he had thought of the dog as one of his customers."和最后一段中的"…he found that there were not any words on it!"可知，卖肉的人从第三次开始就没有看纸上的字，而是直接把肉给了小狗，后来卖肉的人发现小狗送来的是白纸，说明小狗认为只要带一张纸，就能得到一块肉，故选B项。
2.答案：1.D; 2.A; 3.A; 4.B
解析：1.D。根据“Sometimes owners forget that their cats are just as used to the warm shelter as they are.”可知,猫等宠物也像人一样习惯于暖和的住所,所以D正确。
2.A。根据第二段中的“If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too.”可知:当你感到冷的时候就会进房间,它们也是如此,所以A正确。
3.A。根据文章第三段中的“a water bowl has frozen and their pet can’t get anything to drink”可知,当水盆被冻之后,宠物就可能找不到干净的水喝,故选A。
4.B。根据第一段的中心句“There are things you can do to keep your animal warm and safe. ”可知,这是一篇说明文,其目的是为了给养宠物的人们一些实用的建议。
3.答案：1.A 2.C 3.A 4.B
解析：1.推理判断题.根据第一段中的“can be heartbreaking; survival is never certain”可知,拯救野生动物的工作有时令人心碎,因为动物不一定能活下来,也就是说可能会徒劳无功,由此可知答案为A项.
2..细节理解题:据第二段中的“She had found a young owl on the ground.” 和第三段中的“ examined the chick and it seemed fine.”可知,接到一个居住在Mutton town的妇女的电话,是赶过来看看这只雏鸟的情况,此可知答案为C项.
3.细节理解题.跟据第四段中的描述可知作者给这只雏鸟制作了一个安全舒适的新巢,它放进去后,它很快就安静了下来.此可知答案为A项.
4. 推理判断题。根据前文描述可知作者为小猫头鹰做了窝，并且帮助它找回了它的父母。小猫头鹰的父母还为它带回了午餐。作者的救助成功了，说明结局是美好的。再结合第一段的However, when it works, it is simply beautiful.可推测，作者感觉很美好。故选B。
4.答案：1-4.ACBB
解析：语篇解读:本文是一篇关于动物保护的说明文。目前,世界范围内动物的数量正在不断下降,保护动物刻不容缓。保护动物不仅是为动物,也是为我们人类自己的生存考虑。幸运的是,现在有的国家已经开始行动,例如成立保护组织或设立法律等对动物进行有效的保护。
1.解析:标题归纳题。文章提到的动物面临的生存现状、保护动物的必要性以及目前一些国家对野生动物采取的保护性措施等方面都体现了保护动物的主题,故文章标题应是“保护动物”。
2.解析:细节理解题。根据第四段中"Animals are more than... in the balance of nature."可以看出,每一种动物的存在都是有道理的,都是为了维持自然界的平衡。
3.解析:细节理解题。根据第三段中的"Because we need animals."可确定A项正确。根据第四段中的"Every animal has its place in the balance of nature."可确定C项正确;根据第二段中的"Thousands of kinds of animals have disappeared from the earth forever."可确定D项正确。B项说法过于绝对,由文章最后一段中"These laws forbid the killing of any animal or plant on the danger list."可知B项错误。
4.解析:推理判断题。根据第一段和第四段的描述可以看出,以前人们对于动物的保护并不关注,当然也并未意识到动物保护的重要性,故A项错。通过对文章第四段的理解可以得知动物在人们的生活中起着重要作用,故B项正确。文中提到鹰的数量由于人类的捕杀而减少,但并非现在的情况,故可排除C项。D项中提到许多国家制定了法律来禁止对一切动物的捕杀,忽略了文中on the danger list这个说法,故该项是不对的。
5.答案：DFBEG
解析：语篇解读:本文是说明文。文章介绍了动物如何抵御寒冷,以及在冰天雪地如何行走。
①解析:根据下一句"It keeps the inner coat of soft fur warm and dry."可知,D项“外面的皮毛几乎垂到地面”符合语境。D项中的outer coat与下一句中的inner coat相呼应。
②解析:根据该空前的"changes its coat to match the season"和该空后的"In winter it grows white fur to match the snow."可知,雪兔的皮毛为了和不同的季节保持协调而发生变化,因此F项介绍雪兔的皮毛在夏天时的情况符合语境。F项中的In summer和下一句中的In winter形成对比。
③解析:根据该空后的"an extra layer under its fur coat too"可知, B项“你在外套里面穿毛衣吗 ”符合语境。B项中的"a sweater under your coat"与下一句中的"an extra layer under its fur coat"相呼应。
④解析:根据该空前的"it adds something"可知,北极狐的尾巴还可当作围巾使用,包裹鼻子和脸。故选E项。
⑤解析:根据该空前的"A polar bear's big feet act like snowshoes"可知,北极熊宽大的脚可以分摊自身的重量并且保证它们在雪上轻松行走。故选G项。

7.答案：
Paragraph 1:
Upset as I was, I had to walk Misty while seeking a job. I felt it a heavy duty to apply my energy to the routine walk. Every time I walked Misty, I felt exhausted and fed up. One day, Misty stopped in front of me, unwilling to move forward despite my dragging the rope. Dramatically, all my anxiety, exhaustion and displeasure erupted like a volcano. I knelt down, burying my head in my hands, tears rolling down my face. Then, Misty approached me and laid her head on my knees to comfort me. I was a little embarrassed but grateful for Misty’s understanding.Then I stood up, with my steps firm and powerful.
Paragraph 2:
Months going by, my life changed a little and I came to enjoy my walks with Misty. It felt more like relaxation than duty. Misty shared my negative feelings and kept walking peacefully, which comforted me a lot. Thanks to Misty’s silent companion, I regained the enthusiasm to life and finally went through the hard times. With my unremitting efforts, I eventually got a new job, and so did Joe. Everything seemed to be just fine and my family went back to routine. But something did change—I had an earnest and faithful friend.
8.答案：1.Hunting 2.greatly 3.out 4.being harmed 5.with 6.(should) take 7.nature 8.have succeeded 9.worse 10.measures
解析： 1.动名词作主语。
2.修饰动词需用副词。
3.固定短语die out"灭绝"。
4.介词后面跟动名词，句子的宾语wild animals是harm动作的承受者，故用动名词的被动形式。
5.固定短语in harmony with。
6.考查虚拟语气，suggest表示"建议"之意时，后面的宾语从句中用should+动词原形，should可以省略。
7.表"自然保护区"之意时，用名词修饰名词，表示类别。
8.时间状语so far"迄今为止"和完成时态连用，本空指现在情况，故用现在完成时。
9.理解句意可知，本句是指阻止情况变得更糟糕。
10.该名词表示"措施"之意时，是可数名词，被these修饰，故用复数形式。
9.答案：
Dear Editor,
I've just learnt the news online about killing Siberian tigers and I am so sorry. I think Siberian tigers must be protected well, or they will die out. It's time that we took action to protect them from being killed.
It's said that the population of Siberian tigers is getting smaller and smaller. I think there are two main reasons for this. The first reason is that some people kill Siberian tigers for their skins and bones to earn money. The other reason is that too many trees have been cut down, which has destroyed the places where Siberian tigers used to live.
We should work together to make a pleasant home for both human beings and animals. I hope that the government will pass laws to protect Siberian tigers and punish the tiger hunters, because protecting animals is protecting ourselves.
Yours sincerely,
LiHua
