完成下列各题 A The sea is very big. Look at a map of

the world. There is less land than sea. The sea covers three quarters of the world. The sea is very deep in some places. There is one spot, near Japan, where the sea is nearly 11 kilometres deep. The highest mountain in the world is about 9 kilometres high. If that mountain were put into the sea at that place, there would be 2 kilometres of water above it. If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers,which flow into the sea, carry salt from the land into the sea. Some parts of the sea are less salty than other parts. There is one sea, called the Dead Sea, which is very salty. Because it is very salty, swimmers cannot sink! Fish cannot live in the Dead Sea. In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are very small. It is hard to see them. Many fish live by eating these. The sea can be very cold. Divers, who dive deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear elopes made of metal. One spot of the sea near Japan is

A.nearly nine kilometres deep

B.almost eleven kilometres high

C.two kilometres above the highest mountain in the world

D.two kilometres deeper than the height of the world's highest mountain

请根据以下内容回答下列各题 Insurance （保险)is the sharing of risks. Nearly everyone isexpo

请根据以下内容回答下列各题 Insurance (保险)is the sharing of risks. Nearly everyone isexposed to risk of some sort. The house owner, for example, knows that hisproperty can be damaged by fire; the ship-owner knows that his vessel may belost at sea; the breadwinner knows that he may die at any early age and leavehis family poorer. On the other hand, not every house is damaged by fire norevery 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 otherwords, the losses of the few are met from the contributions of the many. Thisis the basis of insurance. Those who pay the contribution are known as insuredand those who administer(管理)the pool of contributionsas insurers. The legal basis of all insurance is thepolicy. 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 sumof money, called the pre- mium(保险费), which is usually paid every year, the insurer will pay a sum ofmoney or compensation for loss, if the risk or event insured against actuallyhappens. The premium for an insurance naturally depends upon how likely therisk is to happen, as suggested by past experience, ff companies fix theirpremiums too high, there will be more to make the premium too low, they willlose money and may even have to drop out of busi- ness. So the ordinary forcesof supply and demand keep premiums at a level satisfactory to both the insurerand the insured. According to the writer, insurance is possible because__________

A.only a small proportion of the insured sufferloss

B.only insured people suffer loss

C.nearly everyone suffers loss

D.everyone at some time suffers loss
