(2013 宝山一模)‎ Venezuela（委内瑞拉）has produced many successful beauty queens, winning both Miss Universe（环球小姐）and Miss World five times. Many Venezuelan girls believe that they can gain confidence, poise（体态）, public speaking skills and better ways to prepare for the future in beauty pageants（选美比赛）. From a very young age, girls in this country grow up dreaming of becoming Miss Venezuela. In Venezuela, the term(称谓) “Miss” as in “Miss Universe” is an honored ___1____.‎ These days, people in some countries consider beauty contests to be silly. They have tried to stop these contests, saying the contests treat women as objects（物品）and place too much importance ____2____ women's looks. Others even say that all the girls that go there are made in a lab and they are made to look less like themselves, and more like the “ideal”（完美形象）. But in Latin America, beauty contests are a source of pride.‎ Are Venezuelan women really more beautiful than other women? “They are not really more beautiful here,” says Selena, who trains girls for the contest. “It's just that the girls here work harder and prepare more than anyone else.”‎ The preparation takes many hours a day. The contestants（竞赛选手） stretch（伸展）their bodies and practice their walks down the runway. They work on their speeches and practice answering questions such as, “Whom do you admire most in the world?” They starve（挨饿）to ___3__ slim. They take classes to learn how to style their ____4____ and apply make-up（化妆品）.‎ It isn't easy. One Miss Universe winner immediately put on 20 pounds after the contest. She said the only thing she wanted to do after the contest was to eat. The cost is ___5____as well. Fortunately the television station that holds the contest pays the costs.‎ Yet most of the contestants say it's worth the effort. A former Miss Universe is now mayor（市长）of a large city. Although she had no political experience before ___6____, she has been asked to run for higher political office. Winners have an advantage they could not get anywhere else. “It's the only chance you have to make it.” says one contestant. “You can't get these opportunities by any other way.” ‎ ‎1.‎ A) prize ‎ B) title C) fame ‎ D) name ‎ ‎2.‎ A) of B) in C) to D) on ‎3.‎ A) look B) seem C) stay D) make ‎4.‎ A) hair B) clothes C) bodies D) steps ‎5.‎ A) high B) expensive C) much ‎ D) large ‎6.‎ A) this B) that ‎ C) it D) those KEYS: BDCAAB 教学建议：‎ 1． 规定学生必须在15分钟内完成；‎ 2． 相互交换批改，表扬正确率最高的学生；‎ 3． 做对的学生给做错的学生讲题；‎ 4． 让每个学生简单总结一下错误原因及应该注意的问题。‎ Choose the best answer.‎ PART I.‎ 1. ‎—May I play computer games, Mom?‎ ‎—No, you ____________.‎ A. don’t B. can’t C. wouldn’t D. won’t 2. ‎—Dad, must we wait until the light becomes green?‎ ‎—Yes, I'm afraid we______ .That's the traffic rule.‎ A. can B. may C. have to D. need 3. ‎_ I see your ID card, sir?

Answer the questions（根据短文内容回答下列问题) (2013 奉贤一模)‎ How to be a good detective Have you seen the Hollywood movie Sherlock Holmes? Holmes is a character created by British writer Sir Arthur Conan Doyle. His books were so popular that Holmes soon became “the most famous detective in the world”. What do you need to be a good detective? The movie Sherlock Holmes will show you.‎ In this movie, this great detective faces a dangerous man, Lord Blackwood. Together with his best friend Dr Watson, Holmes stops Blackwood’s plan to control the world with black “magic”.‎ Most of us are not as intelligent as Holmes. But we can also work out mysteries on our own. All we have to do is to follow some simple rules. ‎ Rule No. 1: Justice (正义) is most important.‎ No matter how smart he or she is, the most important quality for a detective is being good. In the movie, Lord Blackwood and Sherlock Holmes are both very intelligent. The difference is that Lord Blackwood is a bad man and he does bad things. Holmes can beat him on the side of justice.‎ Rule No. 2 Have sharp eyes Every bad man tries to cover up what he did. But not all things can be covered up easily. A good detective can discover clues hidden at crime scenes with sharp eyes. For example, Holmes can simply look at a man’s footprints and quickly find out his personal information like age and habits.‎ Rule No. 3: A good assistant is a great help.‎ Even though Holmes has knowledge about many subjects , such as chemistry, botany(植物学) and anatomy, he still needs Dr Watson’s help to fight with him. We should also have someone to help you, especially if you don’t know as much as Holmes.‎ Rule No. 4: Logic (逻辑) is the key.‎ A good detective never jumps to conclusions. When all the necessary clues are put together, you’d better think carefully. If you can’t work it out, don’t be afraid. Just take a deep breath and concentrate on thinking. Logic can help you discover missing clues. ‎ ‎1.
