　　Insurance(保险) is the sharing of risks. Nearly everyone is exposed(面临) to risk of some sort. The house owner, for example, knows his property can be damaged by fire; the ship－owner knows that his vessel(商船) may be lost at sea; the breadwinner(养家糊口的人) knows that he may die at an early age and leave his family poorer. Cm 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 contributions 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, which is a printed form of contract(合同) on 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(补偿) for loss, if the risk or event insured against actually happens.

　　The premium for an insurance naturally depends on how likely the risk is to happen, as suggested by past experience. If companies fix(确定) their premium too high, there will be more competition in their branch of insurance and they may lose business. On the other hand, if they make the premium too low, they will lose money and may even have to drop out of business. So the ordinary forces supply and demand keep premium at a level satisfactory to both the insurer and the insured.

1．According to the writer, insurance is possible because ________.

[　　]

A．everyone at some time suffers loss

B．only a small proportion of the insured suffer loss

C．nearly everyone suffers loss

D．only insured people suffer loss

2．By “the pool of contributions” the writer means ________.

[　　]

A．money paid by the insured

B．money paid by the insurers

C．the cost of administering insurance

D．the amount of each premium

3．A policy is ________.

[　　]

A．a check to be cashed at the bank

B．a legal agreement

C．a particular kind of insurance

D．money paid by the insured

4．Insurance premiums do not become too high because ________.

[　　]

A．not many people suffer loss

B．not many people insure themselves

C．insurance companies compete with each other

D．they are fixed according to how likely the risk of loss to happen

5．According to the writer, insurance is ________.

[　　]

A．costly but worth buying

B．cheap but not necessary

C．useful but too risky

D．useful and necessary

　　Insurance is the sharing of risks. Nearly everyone is exposed to risks of some sorts. The house owner，for example，knows that his property can be damaged by fire；the ship owner knows that his vessel（船） may be lost at sea；the father knows that he may die at an early age and leave his family the 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 contributions are known as “insured” and those who control the pool of contributions as “insurers”.?

Not all risks lead themselves to being covered by insurance. Broadly speaking，the ordinary risks of business cannot be covered. The risk that buyer will not buy goods at the prices offered is not of a kind that can be estimated（估计）in numbers—and risks can only be insured against if they can be estimated.?

　　The legal basis of all insurance is the “policy”. It states that in return for 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 for loss，if the risk or event insured against actually happens.?

     Even facts " forgotten" by people during a busy day may beretrieved if this is followed by a good
night's sleep. Researchers from the University of Chicago asked volunteers to remember simple words.
Many found their memories letting them down towards the end of the day, but the following morning,
those who had slept well could recall much more. Reserchers , writing in  the journal  Nature .said  the
brain  coud  " rescue"lost memories during the night.When the brain is first asked to remember something
that memory is laid  down  in  an " unstable " state, meaning that it is possible that it could be lost. At
some point, the brain consolidates those it deems important into a "stable" , more permanent state.
     However, the Chicago researchers suggested that it was possible for a " stable" memory to be made "
unstable" agan.This would  mean  that memories could be modified then filed away again in the face of
new experiences.
The 12 volunteers tested in the experiment were played words created through a speech synthesizer
which were purposely difficult to understand. Initially, the written version of the word was available,but
after wards the volunteers were asked to identify the word from the audio version only. Tests revealed
that the ability to recall the right word tended to tail off as the day ended.
     However,when the volunteers were retested after a good night's sleep,they were able to recall some
words that they had"forgotten" the previous evening. Dr Daniel, one of the study authors, said : " Sleep
consolidates memories , protecting them against subsequent interference or decay. Sleep also appears
to "recover" or restore  memories. " He said : " If performance is reduced by decay , sleep might actively
recover what has been lost. "
     Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: " Memory
research is undergoing a transformation-no longer is memory thought to be a hard-wiring of' the brain ,
instead it seems to be a process of storage and restorage. "
     Sleep helps some memories " mature" and also prunes out unimportant memories..

1. What does the first paragraph implies?

A. A busy day makes people forget things easily.
B. People need a good night's sleep after a busy day.
C. A good night's sleep helps memories.
D. A good night's sleep helps people forget a busy day.
