5 阅读理解。 Suppose you don’t need your car today. And suppose, as it happens, that a stranger in your area does need a car. Would you be willing to rent yours out? Several car-sharing start-ups, including Getaround, RelayRides and JustShareIt, are eager to connect car owners with renters this way. The companies have different rules, but participatingo wners receive, generally speaking, about two-thirds of the rental earnings. RelayRides says an owner of a midsize, late-model sedan who rents out a car for 10 hours a week could expect to clear about ＄3,000 a year. Peer-to-peer car sharing remains in the trial stage; it can be found in San Francisco and a few other places. It has a long way to go before it becomes the auto equivalent of Airbnb, the surprise success story for peer-to-peer sharing of space in apartments and houses. Shelby Clark, founder of RelayRides, says potential investors in his company have been concerned that owners will be afraid to hand their car over to strangers. To address that, he points to Airbnb, saying, “Letting people sleep in your living room is much more of a disturbance into your personal space than letting someone use your car.” All of these c ompanies offer their own insurance coverage for their renters, which are supposed to put owners’ minds at ease. But only two states-California and Oregon-have passed laws to clarify that an owner will not suffer any consequences should a car-sharing renter have an accident. “In all the other states, legal ambiguity remains,” Shelby Clark says. “If a renter should be involved in a serious accident in those states, the victim can be expected to go after every party possible, including the car’s owner.” Also to remove the worries of car owners, the driving records of renters are checked for recent serious violations. 1. What does the underlined word “sedan” in Paragraph 2 probably refer to?______ A. A kind of car. B. An owner of a car. C. A renting company. D. A car-sharing renter 2. Which of the following is true of Airbnb? ______ A. It cares little about personal privacy. B. It deals with house-sharing successfully. C. It is a very popular car-sharing company. D. Its ideas are being tried out in some states. 3. If a car-sharing renter should have an accident in California, the car’s owner ___ . A. has to take legal responsibility B. will not suffer the consequence C. is not covered by health insurance D. must pay the insurance for the renter 4. According to the text, more car-owners will participate in the service, if _ A. legal ambiguity is clarified in all the states B. renters are warned not to violate traffic rules C. more money is given to participating owners D. people are aware of the importance of sharing 5. It can be learned from the text that car-sharing A. makes no profit B. remains in popularity C. is against the state law D. is a new business model

9 下列句子中加点的成语使用恰当的一句是（） A.我国西部地区如能用好政策，更新观念，大胆创新，那么迅速赶上沿海发达地区，甚至青出于蓝而胜于蓝，是完全可能的。 B.布什是参加国卫队而不用去越南；凯里是先不想去后来不能不去时，选择了风险较小的海军。你看，这不是五十步笑百步吗？Ｃ.铁头气得二目圆睁，指着李逸风的鼻子说：“要不你走，要不我走。反正今天这个场合一时无两！” D.我们中学生写记叙文，一般是一千字左右，如果把人物语言写得繁文缛节，那就是不简洁了，会削弱文章的感染力量。
