However, many wild animals are facing the danger of dying out, 1 the environment (环境) where they are living has changed greatly. 2 example, their living area has become smaller and smaller because of the development of cities and pollution (污染). They have no room to live in except zoos. And many of the wild animals now can’t find enough food to eat. At 3 same time, people kill animals just for their skin, teeth and meat. 4 (thousand) of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds of animals in the United States alone are considered in danger. We should tell more people about these animals’ stories 5 (make) them care about wildlife. Every animal has 6 (it) place in the balance of nature. Destroying one kind of animal can create many problems. People should realize how 7 (seriously) the situation is and something should be done to protect the animals. We are supposed to set up some nature reserves (自然保护区) so that animals can live 8 (safe). If we don’t take action, the situation will be more and more serious. We are not alone on Earth. We human beings could not live without all the plants and animals around us. So 9 (protect) wild animals is very important. We must take actions to keep plants from being destroyed and stop animals from being killed. If each of us can plant a tree and build a bird house, the world will be much 10 (much) beautiful. Passage B 阅读下面短文，在空白处填入适当的单词或括号内单词的正确形式。 Animals are important in Indian culture and people treat them in 1 special way. For example, a lot of elephants aren’t wild. They are domesticated (驯养). People don’t keep them as pets, 2 as working animals. Every working elephant has its own keeper. An elephant and its keeper meet for the 3 (one) time when they are both young, and they grow up together. 4 (actual), their relationship keeps for the rest of the 5 (elephant) life—perhaps 40 years. Lots of elephants work in the forest to move heavy trees. Some give rides to tourists, or carry people 6 celebrations and festivals. Keepers take excellent care of their elephants，feed them well and give them a bath at the end of the working day. Another special animal in India is the cow. Cows 7 (be) animals people must protect, so people can’t keep them on farms or kill them for food, although people use 8 (they) milk. So in India you can often see cows walking around towns and cities, and nobody 9 (feel) strange. If they sit down in the middle of the road, people have to drive around them! Do you think it’s 10 (interest)? Passage C I had a dream of having one dog, especially the Labrador (拉布拉多猎犬). I told this to my parents 1 they always said Labradors were too expensive. We just didn’t have enough room for it to run, because we were not wealthy (富裕的) and lived in the suburbs (郊区). Time 2 (go) by and my love for this beautiful animal grew. Finally at the beginning of my senior high school, my parents decided to move from the suburbs 3 the country, where we would have much space. My dream finally came true. My parents asked me to go with them to pick out 4 Labrador puppy. When we got to the farm, there were only five puppies left. I decided to pick each one up to get a closer look. And besides, who could refuse to pick up 5 (love) puppies? They all looked the same to me. After I picked up the first four, I thought it would be a hard decision. All the dogs seemed to have the same lazy state (状态). The last one picked up was 6 (ugly) of all. One of the 7 (reason) I picked him up last was that I had a bit of difficulty trying to catch him. The puppy’s owner told me he didn’t think they wanted that one, because it was the weakest (虚弱的). As I examined (检查) him, I looked right into 8 (he) eyes, bringing him close to my face, weak or not? I knew this was the one I wanted because he licked (舔) my face. That little show of love was all I needed 9 I knew that this was my dog. In our life, the most beautiful thing is always hard to get close to. Only the proper (合适的) choice belongs 10 your heart. 2 学科网（北京）股份有限公司 $
