Unlike X-rays and gamma rays, which are very powerful rays of radiation, microwaves are rather weak and are much more like the waves of radiation used in radio broadcasting.In microwave ovens, the use of microwaves with which most people are familiar, the waves are produced by an electronic tube called a magnetron. Microwaves produce beat in any food placed inside the oven by causing the water in the food to vibrate rapidly and thus heat up. Food that have more water in them take less time to cook and probably have more of their nutrients left intact when cooked in a microwave oven.Microwaves do not pass through metals so the microwaves are retained within the oven. Microwaves pass immediately through glass, paper, and plastic with no effect on these materials or on the microwaves; nothing inside the microwave oven is heated except the food itself, so the cooking process is much more efficient than in conventional ovens. Sometimes a part or container is heated because it is touching the hot food, though; some users of microwave ovens have been burned by hot food, by hot pans, or steam escaping from the food. No documented case of radiation burns from a microwave oven has ever been reported.Actually, we know very little about how microwave radiation might affect human beings. Obviously, if microwaves can cook a roast by exciting the water molecules in the meats they could do the same thing to human flesh. Human being could be burned by prolonged exposure to high levels of microwaves. But scientists are more concerned about the effects of low level microwave exposures, such as might result from a leaking microwave oven.No research has yet been performed on people who have been exposed to low level microwave radiation. Some experiments have been performed on animals, but the results are very difficult to interpret. As the eyes are particularly sensitive, rabbits exposed to low level microwaves were checked for the growth of cataracts, and none were found. On the other hand, some animals seem able to sense microwave radiation and try to escape from it immediately. In others, microwave radiation causes the body to react as if defending itself against decease. These responses lead some scientists to think that microwave radiation is harmful,though in some yet undiscovered way.1. The purpose of this passage is to discuss( ).2. Microwaves are( ).3. We can conclude from this passage that( ).4. The authors tone is( ).5. As used in the 3rd paragraph of this passage, the word “documented means( ).问题1选项A.the beneficial use of microwavesB.the harmful effects of microwavesC.the modern methods of cookingD.the use and possible harmful effects of microwaves问题2选项A.absolutely safe at low levelsB.very efficient for cookingC.cancer-causing in people with weak eyesD.completely understood by Scientists问题3选项A.the heat created in microwave ovens is very difficult to controlB.food tastes better when cooked in a microwave ovenC.food cooked in microwave ovens is probably more nutritious than food cooked in more conventional waysD.most research on the effects of microwaves on human beings has been restricted to the study of low level microwave radiation问题4选项A.objectiveB.sarcasticC.negativeD.skeptical问题5选项A.numberedB.recordedC.legalD.believable【答案】第1题:D第2题:B第3题:D第4题:A第5题:B【解析】1.主旨大意题。本文第一段介绍了微波的特点,第二三段讲述了微波的用途,最后分析了微波可能对人体造成的伤害。故D项“微波的用途及可能造成的影响”正确。ABC三项均比较片面。2.推理判断题。由第三段“nothing inside the microwave oven is heated except the food itself, so the cooking process is much more efficient than in conventional ovens. 除了食物本身,微波炉里的任何
