单选题Insomnia (失眠) is the inability to sleep calmly and relaxedly. It is a problem to nearly everyone at some time. A person may be awake for an hour in the middle of the night and then, next morning, may feel that he hardly slept all night. Normally, worry about not getting enough sleep is the worst aspect of most insomnia. If insomnia occurs repeatedly, it is important to find its possible causes and try to correct them. Any of simple factors may make one feel difficult to fall asleep. His mattress (床垫) may be too soft or too hard. If there are too many blankets (毯子) on a hot night, he may be too warm; if the mattress is too light he may feel cold during the night. The bedroom itself may be overheated or too cold. If it is not dark enough, or too noisy, this may cause difficulty in sleeping. Eating shortly before going to bed may also be responsible for insomnia. Drinking tea or coffee can also make people awake. The cause of insomnia may be easy to correct. The sufferer should check the mattress, and bedroom temperature, and make any necessary changes. He should relax for an hour or two before bedtime, perhaps by reading a book, watching television or taking a warm bath. If he wakes during the night he should try turning on the light and reading for a while. Taking warm milk and a biscuit or two may be helpful.

单选题Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 to 45. Surprisingly, there is a relationship between sea salt and the making of rain drops. Most of the water droplets that make up clouds are formed around small, solid particles. In order to fall as rain, the cloud droplets have to increase in size. Clouds from which rain does not fall have droplets that are fairly uniform in size. Clouds that produce rain have some droplets that are much larger than others. The production of rain depends on the presence of the large droplets that grow in size by coalscence (聚结). There is evidence to support the theory that a particle of sea salt serves as the nucleus (核心) or center, around which the larger droplets form. Most of the sea salt probably enters the atmosphere from, bubbles that form on the surface of the sea. When the bubbles break, a tiny, even microscopic, droplet of salt water is cast into the air. Once in the atmosphere, the microscopic piece of salt collects water vapor from the air. The water vapor then condenses on the particle of salt. The moisture absorbed by the salt particles dissolves the salt, thus leaving only a slightly salty cloud droplet. Cloud droplet, formed from condensation of salt particles of dust particles. The reason is that salt particles are usually larger than dust particles. Their larger size is instrumental(有作用的) in making the single rain droplet grow by coalescence with smaller droplets. Since low level clouds don't rise high enough to produce ice crystals as a source of condensation, it most likely is the salt particles that cause them to become rain clouds.

单选题Over the centuries, scientists have been trying hard to find satisfactory substitutes for precious stones but failed many times. Many years ago, a chemist surprised the world by saying: It should be possible to make a precious stone that not only looks like the real thing, but that is the real thing. The only difference should be that one crystal would be made by man, the other by nature. At first this did not seem like a particularly hard task. Scientists began to try making synthetic diamonds towards the end of the eighteenth century and discovered a key scientific fact: diamonds are a form of carbon, which is a very common element. Then, why not change a cheap and plentiful substance, carbon, into a rare and expensive one, diamond? This change takes place in nature, so it should be possible to make it happen in the laboratory. It should be possible, but for 150 years every effort failed though several people believed that they had solved the diamond riddle during this period. The real success came after the scientists realized that, in changing carbon into diamonds, unbelievably heavy pressure and extremely high temperature are indispensable, and carbon needs to be dissolved (溶解) in a metal that helps the reaction to take place more easily. Under these conditions, a number of shiny crystals were produced in the laboratories of the General Electric Company. The results of careful analysis showed that the chemist was right: these jewels of the laboratory were not like diamonds; they were diamonds.
