题目内容

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbooks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全书), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
【小题1】It can be inferred from the passage that ________.

A．TV programs are a chief provider of knowledge

B．cinemas are the best choice in getting information

C．reading is a cheap way of learning and having fun

D．newspapers are an expensive way to enjoy oneself

【小题2】What does the sentences “Television has not killed reading, however ” underlined in the second paragraph suggest?

A．People only need reading, though.	B．Reading is still necessary today.
C．Reading is more fun than television.	D．Watching television doesn’t help reading.

【小题3】What can we learn from the passage?

A．Fewer and fewer people will buy books.

B．A good dictionary should be kept in every home.

C．Books with hard covers sell better than paperbooks.

D．More people like TV programs about famous men.

【小题4】What can we learn from the passage?

A．Fewer and fewer people will buy books.

B．A good dictionary should be kept in every home.

C．Books with hard covers sell better than paperbooks.

D．More people like TV programs about famous men.

【小题1】C
【小题2】B
【小题3】A
【小题4】B

解析【小题1】判断推理题。从第二段的最后几行可知。
【小题2】第二段第一句Television has not killed reading, however.是本段的主题句。上文讲到人们看电视越来越多，行文到此，来一个转折，尽管如此，阅读在人们的日常生活中仍然是必需的。
【小题3】总结归纳题。第一句…and some types of books should be in every home. 接下来详述在每一个家庭中常有哪些类型的书籍。
【小题4】细节查找题。最后一段Every home should have a good dictionary. 可知。

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 ________.

A. neutral B. negative C. positive D. indifferent
