单选题{{B}}Task 2{{/B}} Sleepwalking is a scientific reality. It's one of those strange phenomena that sometimes border in the fantastic. What is certain about sleepwalking is that it is a symptom of emotional disturbance, and' that the only way to care it is to remove their worries and anxieties that eaus6 it. Doctors say that sleepwalking is much more common than is generally supposed. {{U}}Many sleepwalkers do not seek help and so are never put on record, which means that an accurate count can never be made.{{/U}} The questions: Is the sleepwalker actually awake or asleep? Scientists have decided that he is about half--and--half. Doctors think the sleepwalker is awake in the muscular area, partially asleep in the sensory area. In other words, a person can walk in his sleep, move around, and do other things, but he does not think about what he is doing. What are the chances of a sleepwalker committing a murder or doing something else extraordinary in his sleep? In general, authorities in sleepwalking think that people will not do anything in their sleep that is against their own moral standard. As for the publicized cases, Dr. Teplitz points out, "sleepwalking itself is dramatic--sleepwalkers can always find an audience. I think that some of their tall tales get exaggerated in the telling. "In her own records of case histories, there is not one sleepwalker who ever got beyond his own front door. To protect themselves, some sleepwalkers have been known to tie themselves in bed, lock their doors, hide the keys, bolt the window, and take all sorts of measures to wake themselves if they should get out of bed. Curiously enough, they have an unusual way of avoiding their own traps when they sleepwalk, so none of their tricks seem to work very well. Some sleepwalkers talk in their sleep loudly enough to wake someone else in the family who can then shake them back to their senses. Children who walk in their sleep usually outgrow the habit. In many adults, too, the condition is more or less temporary. If it happens often, the sleepwalker should seek help. Although sleepwalking itself is nothing to become alarmed about, the problems that cause the sleepwalking may be very serious.

单选题The advantages and disadvantages of a large population have long been a subject of discussion among economists. It has been argued that the supply of good land is limited. To feed a large population, inferior land must be cultivated and the good land worked intensively. Thus, each person produces less and this means a lower average income than could be obtained with a smaller population. Other economists have argued that a large population gives more scope ]for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify them. One of the difficulties in carrying out a world - wide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, it will be the first concern of government to place a limit on the birthrate, whatever the consequences may be. In the highly industrialized society, the problem may be more complex. A decreasing birthrate may lead to unemployment because it results in a declining market for manufactured good. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.

单选题What is the effect of this purchase according to the passage?

单选题 All of us communicate with one another nonverbally (不使用言语地), as well as with words. Most of the time, we are not aware that we are doing it. We gesture with eyebrows or a hand, meet someone else's eyes and look away, change positions in a chair. These actions we assume are occasional. However in recent years researchers have discovered that there' is a system to them almost as consistent (一致的) and understandable as language. One important kind of body language is eye behavior. Americans are Careful about how and when they meet one another's eyes. In our normal conversation, each eye contact lasts only about a second before one or both of us look away. When two Americans look searchingly into each other's eyes, they become more intimate. Therefore, we carefully avoid this, except in suitable situations. Researchers who are engaged in the study of communication through body movement are not prepared to spell out a precise vocabulary of gestures. When an American rubs his nose, it may mean he is disagreeing with someone or refusing something. But there are other possible explanations, too. Another example: when a student in conversation with a professor holds the older man's eyes a little longer than usual, it can be a sign of respect; it can be a challenge to the professor's authority; it can be something else entirely. The researchers look for patterns in the situation, not for a separate meaningful gesture. Communication between human beings would be just dull if it were all done with words.

单选题An earthquake is caused by a sudden slip on a fault (断层). A fault is a fracture in the crust (地壳) of the earth along which rocks on one side have moved relative to those on the other side. Stresses in the earth's outer layer push the sides of the fault together, build up, and then the rocks slips suddenly, releasing energy in waves that travel through the rock to cause the shaking that we feel during an earthquake. Earthquakes tend to be concentrated in narrow zones. There are 7 major crystal plates on earth, about 80 km thick, all in constant motion relative to one another. They move at a rate of between 10 and 130 mm per year. It is estimated that there are several million earthquakes in the world each year. Many of these earthquakes go undetected because they occur in remote areas or have very small magnitudes (震级). The USGS Earthquake Information Centre locates 12, 000 to 14,000 earthquakes each year (about 35 per day). On average, about 60 earthquakes per year are classified as significant, with 19 classified as major. A significant earthquake is one of a magnitude of 6. 5 or higher or one of a lesser magnitude that causes casualties (伤亡) or considerable damage. Major earthquakes have a magnitude of more than 7.0.
