Passage 2 Being a salesman, the most important thing is to understand people. You've got to know what they're thinking. If you can figure that out, you can get them to do a lot. They come in with an idea about what they want. You get them talking about themselves, about what they like. If it's a man, you talk about football, or something like that. If it's a woman, you ask her about fashions. That way they get comfortable with you. You ask them a lot of questions and get them saying yes. Then they just get into the habit of saying yes. In the end, you can put them into anything you want, if you're really good. For example, if they need a little car for the city; you send them home a truck. Of course, I wouldn't really do that. It wouldn't be right. You've got to sell on this job, but you also have to be fair. It'snot fair to take advantage of people too much. There are some people in this business who'd do anything. But I don't believe in that. 36.To be a good salesman, the most important thing is to________.

2015-2016学年度第一学期期末考试考试时间：120分钟满分：150分第一部分阅读理解（共两节，满分 40 分）（共 15 小题；每小题 2 分，满分 30 分）阅读下列短文，从每题所给的四个选项（A、B、C、和 D）中，选出最佳选项，并在答题卡上将该项涂黑。

AHave you ever felt that you want more friends? Have you foun d that you don’t know how to make friends? Don’t worry. It’s e asier than it looks.Start with small actions. If you’re uncomfortable with long con versations with people, start by just saying “hi” and asking wh at the person is doing. Even if you do more listening than talki ng in the beginning, people will usually still like you. When it c omes to conversations, remember “F.O.R.”. It stands for famil y, occupation(职业) and recreation(休闲). You are most likely to be asked about these three topics when you meet someone new. Most people feel comfortable t alking about the three topics. The great thing is that you alsocan communicate with someone new in these three areas. Honesty is the best policy. In friendship, “honesty” is the fund amental quality that one must have. One should always be ho nest with his or her friends. Don’t laugh at people’s fault. Prais e them honestly and openly. Say you are sorry if you hurt you r friend.Give more than you take. Be there when they need you, enco urage them; we all need encouragement now and then. Enco urage their dreams. Life seems meaningless without them. Wi sh your friends good luck. Examine your purpose before you “help out”. Love and never forget them.1. The author thinks making friends is _________.A. difficultB. easyC. funnyD. inter esting2. What does the underlined word “fundamental” in Paragraph3 mean?A. basic.B. beautiful.C. comfortable.D. meani ngful.3. Which would be the best title for this passage?A. Where to Meet Friends?B.

范文： Cheating on Exam With the development of the society, people pay more and more attention to education. As a result, thousands of students take part in various examinations. However, some students have been found cheating on their exams. Some of them copy from each others, some took out their textbooks or reference books to copy, some copied from small pieces of paper on which they had prepared for the exam, still some used the modern communication tools such as BP, mobile phone as a way to cheat on exams. Then, what’s the effect of cheating on exam? There are three factors for this. First, it results in an unfair competition and will destroy the creativity of those bright students. Second, it will ruin the students’ self -confidence in the long run. Third, under that kind of circumstances, the students graduated from the schools will not be the one who can meet the need of the society. However, how to stop cheating on exam? In my opinion, there are two ways we can adopt. First, a severe punishment should be put into effect to prevent students from cheating. Second, great effort should be made to make students understand what kind of person the society needs and try to improve their self-confidence. Part II Listening Comprehension(35 points) 本题为听力理解，共三部分。
