单选题Insurance(保险)is the sharing of risks. Nearly everyone is exposed to risk of some sort. The house owner, for example, knows that his property can be damaged by fire, the ship-owner knows that his vessel may be lost at sea: the breadwinner knows that he may die at any early age and leave his family poorer. On the other hand，not every house is damaged by fire nor every vessel lost at sea. If these persons, each put a small sum into a pool. there will be enough to meet the needs of the few who do suffer loss. In other words, the losses of the few are met from the contributions of the many. This is the basis of insurance. Those who pay the contribution are known as insured and those who administer(管理)the pool of contributions as insurers. The legal basis of all insurance is the policy. This is a printed form of contract on stout paper of the best quality. It states that in return for the regular payment by the insured of a named sum of money, called the premium (保险费), which is usually paid every year, the insurer will pay a sum of money or compensation for loss, if the risk or event insured against actually happens. The premium for an insurance naturally depends upon how likely the risk is to happen, as suggested by past experience. If companies fix their premiums too high, there will be more make the premium too low. they will lose money and may even have to drop out of business. So the ordinary forces of supply and demand keep premiums at a level satisfactory to both the insurer and the insured.

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.
