Though Tom would be away for at least three days, Bill had a strange feeling of his nearness. In the stillness he seemed to hear Toms voice. He turned round quickly, but there was only the girl. The girl carrying an oil lamp led Bill upstairs. She stopped and raised the lamp in each doorway, staring at him meanwhile. Satisfied he was the only guest, Bill came to the last door. You sleep here, sir, she said, giving him the lamp. Your friend slept here, too. Good night, miss, he said politely. Her lips moved in reply, but he didnt catch the words. Her eyes never for a moment left his face. He stepped in, and as he turned to close the door she was still standing there. In the silence he felt a little terrified now. He shut the door in the girls face then, leaving her in the dark. He opened it again almost at once. She had disappeared without a sound. A deep mistrust suddenly came to him. Why had that girl stared at him so?26-30. ADABDV.Translation 31. 针对这种症状最常用的药是盘尼西林。32. 她乐于帮助有困难的人。33. 我的背疼。Unit 6JobI. Communicative English （Choose the best Answer）1. C 2. D3. A4. B5. CII.

CDBAAPassage 2If you travel by air across the center of Africa or South America, you fly over forests for thousands of kilometers. These great forests are the oceans of trees. There are thousands and thousands of different kinds of plants and animals. However, the worlds forests are getting smaller all the time. We are cutting down the trees because we need wood, and we need more farmland. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear? If we cut down our forests, a lot of plants and animals will disappear from the world. In a lot of places the new farmland will soon look like the old deserts. Crops will not grow there. It will not rain very often, and the weather will get very hot. Perhaps the climate of the world will change. This will be dangerous for everyone in the world. That is why we must take care of our forests. 26-30. BBDCBV.Translation 31. 人们运用科学知识了解和改变自然。32. 他不知道人生对他意味着什么。33. 我们期待明天之前她能改变她的想法。Unit 7Taking a standI.

Reading Comprehension (Choose the best answer for each of the questions or unfinished statements after the reading passages.)Passage 121-25. CBBCAPassage 2Our childs behavior is greatly influenced by the way we react to what he has done. Our reactions help to determine whether our child will repeat his behavior or whether he will do something different. This statement is a very important part of a principle of behavioral psychology.The principle states that a behavior is influenced or affected by how the environment - people, places and things - immediately responds to the behavior. Perhaps without realizing it, you have used this principle many times.On the occasion when you told your child what a good boy he was after he cleaned up his room, you used the principle. When you sent your child to his room for fighting with his brother, you used the principle. When I gave Kim a cookie after she started to cry, I used the principle. In each of these examples, a particular behavior occurred first - cleaning up a room, fighting, and crying.In addition, there was a reaction to each behavior - the child was praised, sent to his room, or given a cookie. By these actions, we have influenced the previous behaviors and have helped to determine whether those behaviors will occur again in the future.26-30.
