Some people believe that international sports create goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true: that international competitions encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourage international brotherhood. Not only was there the tragic incident involving the murder of athletes, but the Games were also ruined by lesser incidents caused mainly by minor national competitions.
　One country received its second-place medals with visible indignation（愤慨）after a hockey final. There had been noisy scenes at the end of the hockey match, the loser’s objection to the final decision. They were sure that one of their goals should not have been disallowed and that their opponents’ victory was unfair. Their manager was very angry and he said, “This wasn’t hockey. Hockey and the International Hockey Federation are finished.” The president of the Federation said later that such behavior could result in the suspension（停赛）of the team for at least three years.
　The American basketball team announced that they would not give up the first place to Russia, after a disputable end to their competition. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player popped the ball into the basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury discussed the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals.
　Incidents of this kind will continue as long as sports are played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in non-national teams, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism（爱国主义）.
【小题1】According to the author, recent Olympic Games have ________.

A．caused national pride for athletes

B．created goodwill between the nations

C．hardly showed any international friendship

D．led to less misunderstanding between countries

【小题2】What did the manager mean by saying “Hockey and the International Hockey Federation are finished”?

A．His team would no longer take part in international games.

B．There should be no hockey matches organized by the Federation.

C．Hockey and the Federation are both ruined by the unfair decisions.

D．The International Hockey Federation should be dismissed forever.

【小题3】By taking the basketball game for example, the author wants to prove that ________.

A．too much patriotism was displayed in the games

B．the announcement to prolong the match was wrong

C．the appeal jury was too hesitant in making the decision

D．the team was right in refusing to accept the silver medals

【小题4】What conclusion can be drawn from the passage?

A．Sports should be played for the love of one’s nation.

B．Unfair decisions are common in the Olympic Games.

C．International competitions will lead to misunderstanding.

D．The organization for the Olympic Games must be reformed.

Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.

The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment(色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.

It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(变异) in the gene for melanosome production. This results in less pigmented skin.

However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.

Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun(太阳光紫外线), which can cause skin cancer.

But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.

Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.

The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson.

The passage mainly tells us that ________.

A. people can not change their skin colour without any pain

B. the new discovery could lead to search into ways to change skin colour safely

C. pop king Michael Jackson often changed his skin colour as he liked

D. scientists have found out that people’s skin colour is determined by the gene

It can be inferred from the passage that ________.

A. nowadays people who want to change their skin colour have to suffer a lot from the damage caused by the chemical treatment

B. Europeans and Africans have the same gene

C. the new discovery could help to find medical treatments for skin cancer

D. there are two kinds of genes

Scientists have done an experiment on a dark-striped zebra fish in order to ________.

A. find the different genes of humans’

B. prove the humans’ skin colour is determined by the pigment gene

C. find out the reason why the Africans’ skin colour is dark

D. find out the ways of changing peopl’s skin colour

The writer’s attitude towards the discovery is ________.
