Everyone makes mistakes in life, but for whales and dolphins, the “mistake” of landing on the shore costs the highest price---their lives.

People living along the coast of Australia and New Zealand have been shocked and saddened by the number of whales and dolphins that they have found on their beaches recently. Since November 28th, 96 whales and dolphins have died in Australia and 53 whales died in New Zealand. Although 20 whales were saved, some of these were not expected to live, as they were too weak to swim with the others back to sea.

Bob Brown, leader of Australia’s Green party, said the mass beaching was caused by the recent “sound bombing” of the ocean floor between the two countries. This is a method of testing for oil and gas reserves (储藏量).

But mass beaching of whales has long puzzled scientists. Typically most members of the stranded (搁浅) group will appear to be perfectly healthy. “Some researchers believe that close relationship within the group causes the problem, if one gets into trouble, the others will not leave” said Shery Gibney, a leading biologist in New Zealand. “Some will come in and try and assist it; if they get trapped on the beach, then more will come.”

Another common theory is that the whales’ navigation (导航) system are thought to break down in some way. It has been said that whales follow electromagnetic (电磁的) patterns in the sea-bed. The whales can get confused because these patterns sometimes change. That would be a bit like a new roundabout (环状交叉路) being built on a road you were used to driving on. You might be confused for a minute when you come to it for the first time, and you might even take a wrong turning before getting back on your route.

A different idea is that when whales chase fish for food they end up in shallow waters because they are not paying attention to where they are going.

And yet, from time to time a group will swim on purpose into shallow waters and end up on the beach, where they die. If returned to the sea, some whales often show great determination in restraining themselves.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

What is your favourite colour? Do you like yellow, orange, red? 1.Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist(悲观主义者). At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings. 2.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.

3.. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. 4.. A black bridge over the Thames River, near London, used to be the scene of more suicides(自杀) than any other bridge in the area---until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

5.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

A. On the other hand, black is depressing.

B. They tell us, among other facts, that we do not choose our favourite colour as grow up --- we are born with our preference.

C. The rooms are painted in different colours as you like.

D. If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.

E. Light and bright colours make people not only happier but more active.

F. Life is like a picture or a poem, full of different colours.

G. Colours do influence our moods---there is no doubt about it.
