It cannot be seen or heard, or touched or tasted, even though it exists all around us. There are other things like that. Radio waves are all around us but we cannot detect them, sense them, without a radio receiver. Similarly, we cannot sense radioactivity without a radio detector. But unlike common radio waves, unclear radiation is not harmless to human beings and otherthings.At very high levels, radiation can kill an animal or human being outright by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hurt anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright, your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years.This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can receive radiation and feel fine, then die of cancer five, ten or twenty years later as a result.1.The mystery about nuclear radiation may come from the fact that it cannot bedetected by human senses.A. RightB. Wrong2. We cannot sense radio activity without a radio receiver.A. RightB. Wrong3. Common radio waves are harmless to human beings and other things.A. RightB. Wrong4. Even at the lowest levels, radiation will cause cancer by killing the healthy cells.A. RightB. Wrong5. Victims of nuclear radiation may die of cancer years later.A. RightB. WrongSection C 补全短文Passage 1Many large cities are now anything but beautiful. Streets are littered with trash. In this trash, however, (1 ).If people want to solve the problem of waste, (2). They must work out ways of making use of good things which are just thrown away as waste. When a car gets too old, it may not run any more. But the metal that the car was made of is still good. (3). when a bottle is empty, it goes out in the trash. But bottle glass can be ground into sand and used to pave roads. Garbage from food can be changed into fertilizer. But first you have to fish out all the glass and metal.Furthermore, Garbage can also be a good source for making building blocks, which are then covered with concrete. Now, (4). Some day, people will watch films in a great cinema which has been built out of garbage. Future buildings, roads, and cities maybe made from garbage. But so far, (5).A. there is no time to be lostB. building beautiful cities out of garbage is only a dreamC. there is still something that can be usefulD. It can be put to use again.E. more and more machines are designed for this purposeSection D 阅读理解Passage 1Holidays in the United States usually occur at least once a month. Most months have a national holiday that has been arranged to be celebrated on a Monday. The holidays have all been decided to be celebrated on a Monday so that the workers may have 3-day weekends ----that is, Saturday, Sunday and Monday in order to rest or travel or do things with their families. Major holidays in the United States such as New Year’s Day or Christmas Day or the day, when we remember the first settle rs of the United States, called Thanksgiving Day are celebrated all over the country. During these holidays most businesses close and the workers stay home and celebrate with their families.Vacation can be from 2 weeks a year to 4 weeks a year. This usually depends on how long you’ve been working for a company, what type of position you have,whether you have a very high position or a very important position and it’s difficult to find someone to replace you. In this case, you might take a few days at a time rather than taking one month all at once. Usually the more time you spend working for a company, the more time you may get for a vacation.1. The government of the United States makes it a rule for workers to have a weekend almost once a month.A. 1-dayB. 2-dayC. 3-dayD. 4-day2. Workers in the United States sometimes work from .A. Monday to SaturdayB. Tuesday to SundayC. Thursday to FridayD. Tuesday to Friday3. Which statement is NOT true according to this passage?A. Only a few shops remain open on New Year’s Day.B.

The reason why someone has to divide his vacation into several parts is that .A. no one can be found to take his placeB. he hasn’t a most high positionC. he plays an important role in his workD. he hasn’t been working for his company for a long time5.
