问题 单项选择题

阅读下文,回答第26~30题。  科学家们预言,21世纪将是生物学世纪。生物学世纪将在三个领域中到来:医药、环境整治和农业。  以清除污染为例,新的研究表明,在进化的过程中,自然界曾反复地从微生物中增加或减少基因簇,就像调试计算机时增加或减少程序一样。既然自然界能这样做,今天的操纵者也行。于是一个名为“基因组工程”的新领域诞生了。基因研究所目前在测序的一种细菌可以耐受超量辐射。如果插入了它的铀代谢途径的基因簇,科学家也就能制成可以清除高辐射废物的细胞。  一些乐观的科学家期望着由全能生物导致的绿色高效经济的诞生。这些生物可以做从清理垃圾到用无机物制造甲烷的所有事情。从而可以解决我们面临的紧迫的污染问题。  事实上这种尝试已经开始了。几年前,美国卡纳基研究所的生物学家曾把生产塑料的基因转入拟南芥中,使其成了一个生物塑料工厂。现在,美国科学家使这个概念成了商业现实。科学家预言,到了2003年,全世界许多国家都将大规模种植这种植物。  一些科学家相信,生物学的世纪也会导致电子学的新纪元。在基因的双螺旋中蕴含的信息百万倍于最先进的集成电路,把它作为计算的基础是很吸引人的。在一次DNA计算会议上,美国普林斯顿大学的丹·博涅赫认为,虽然用DNA进行一次计算要花一个小时,而用硅片只要几分之一秒,但硅片一次只能做一件工作,而一台DNA计算机理论上可同时进行十亿亿个工作。当然,要向硅片挑战,DNA仍有很长的路要走。  世界已经飞速走向生物技术的世纪了,连科学家们也不知前景会怎么样。有些学者甚至怀疑人是否具有足够的智慧来了解自身的80000个基因是如何共同作用产生了一个可以注视自己过去与未来的生命的。但是,大家已经认识到,有一点是肯定的,即当我们进入下一个千年时,生物技术将在人类历史上写下自己的篇章。(节选自《克隆震撼》)

IMAGINE that you are in school, giving a speech to your class.

Now think what it feels like when stammering(口吃)makes it a struggle to communicate your thoughts and feelings to other people.

The King’s Speech, which won the best picture at

the Academy Awards, highlights(突出) stammering along with other speech-related problems. The movie tells the story of Britain’s King George Ⅵ, who became king after his brother Edward Ⅷ gave up the crown to marry an American woman.

As a result of British actor Colin Firth’s performance, people are starting to realize that stammering can damage a person’s self-confidence and cause him/her to escape from life.

“The problem is unseen and unheard,” said Norbert Lieckfeldt, an expert at the British Stammering Association, in an interview with The Guardian newspaper.

“Stammering masks(遮盖) your ability,” he said, “It's a serious disability(残疾).”

Most stammerers face bullying(欺负) in school, something that is “usually carried over into the workplace”.

George Ⅵ’s stammer took away his confidence as a speaker. But Samantha Mesango, a speech coach based in the UK, believes that speech problems are more common than most people realize. “Some simply don't like the sound of their own voice; others are scared of speaking in public,” she said.

Travis Treats from Saint Louis University’s department of communication sciences in the US, praised The King’s Speech. He said it shows that “how one’s speech does not mean what one is inside”.

He also added that people who stammer need to be heard and our society should recognize that they have a lot to give to the world.

小题1: What is the point of the first two paragraphs?

A.To tell readers about speech speaking.

B.To show how harmful a stammer is.

A.was a hero during World War Ⅱ

B.took the place of his brother

C.married a divorced American woman

D.was a failure because of his stammer小题3: What is Norbert Lieckfeldt’s view of the challenge of a stammer?

A.A stammer can destroy a person’s self-confidence.

B.A stammer is a serious problem for many people but it is often ignored.

C.People who stammer need to have their own voice.

D.People who stammer do better in work than in school.
