大学英语200909统考模拟在线测试考试(答案)(2)

Trials are taking place in North America and Europe to test an electronic device which will prevent children from watching unsuitable programs on television. The device, known as a V-chip (the “v” stands for violence), allows parents to control their television set so that programs which are unsuitable for children cannot be watched on a particular television. The V-chip works by using an electronic code. When a program is broadcast, the signal from the television transmitter carries a code, which indicates the level of sex and/or violence in a particular program. The V-chip inside the television then examines the code for each program and blocks transmission of those programs which contain certain codes. Makers of the V-chip say that parents can be confident that their children will not be able to watch those programs which they decide are unsuitable. V-chip technology has attracted a lot of interest. President Clinton passed a law last year which will require all new televisions to be fitted with V-chips by 1998. And the European Parliament (欧洲议会) has included the V-chip in its new Directive on Broadcasting. But critics say that the system will not be fool-proof, and that children will find ways of getting around it. There are also concerns that foreign satellite television companies may not abide by the rules. Others say that if viewers come to rely on the V-chip, other controls on program content may start to be relaxed. 16. According to the passage, V-chip technology enables parents to ____C______. 17、 17. What do we learn from the passage about the electronic code? D 18、 18.

A travel agent can give you information on special economy fares for trains, buses and planes. Think about hiking or biking for a part of your trip, too. You’ll not only save money, but you’ll also see a lot more of the country. Some students may want to travel by car. Be sure to think about going with other students — many colleges have “ride boards” that list when and where other students plan to travel. Many radio stations provide the same sort of service — they announce who’s driving where, when, how many riders they will take and what the expenses will be. There are many inexpensive, older hotels near bus or train stations. Check your travel guide for names of the best. Many parts of the country also have youth hostels where young people can stay for only a few dollars a night. You don’t have to eat in restaurants all the time, but we don’t recommend a diet of candy and cola, either. You can usually get a healthy, cheap breakfast in a restaurant. If the weather is warm, you can buy food in supermarkets or at roadside stands and have a picnic for lunch. For dinner you can get the names of good, cheap restaurants from travel guides or friends. 21. The passage tells students ____C____.

After a period at sea she must be overall checked and any necessary repairs must be made. There are also instances when a ship must be converted from being one kind of carrier to another. Most of today’s oil, for example, is carried by huge super-tankers. The smaller tankers, many of which are still in good condition, can be converted into bulk carriers（散货船）for the transport of sugar, coal or ore. Conversion or repair work is carried out in a dry dock, a huge hole cut into the ground and lined with concrete. At one end are large gates separating the dock from the river or sea. When these gates are opened, water pours into the dock and fills it. A ship can then enter the dock, where it is carefully fastened in an upright position. When the ship is positioned inside the dock, the gates are closed and the water is pumped out. The vessel slowly settles on to wooden blocks. Wooden supporters are put in position between the ship and the sides of the dock to prevent her from rolling over. Great care is taken to make sure that the ship rests evenly on the keel（龙骨）blocks to prevent damage being done. As soon as the ship is firmly positioned, repair or conversion work can begin on her body or superstructure. 26. According to the passage, in what way is a ship like motorcar? A 27、 27.

B、It needs to be repaired in a dry dock. C、It can be converted into other kinds of vehicle. D、It has a long working life. 28、 D、many of them are still in good condition 28. We can infer that a dry dock ____A____. 29、 29. What do you think will happen to a dry dock when the repairs to a ship are completed?B 30、 30. According to the passage, how is a ship kept upright in a dry dock?D 31、 第三部分：词汇和结构 （共25小题，每小题1分，共25分） 第一节：此小节共有15个未完成的句子，针对每个句子中未完成的部分有4个选项，请你从A、B、C、D四个选项中，选出可以填入空白处的最佳选项并用铅笔将答题卡上相应的字母按要求涂黑。 31.
