【解析】本文介绍了被成为血库之父Charles Richard Drew,以及他的贡献。

本题考查学生的词汇和语法运用能力。

1考查语态。这里的意思是,非洲裔美国医生Charles Richard Drew被叫做血库之父。根据句意可知用被动语态,根据语境,这里可以用一般现在时或者一般过去时,故is/was called。

2考查形容词性物主代词。这里说的是,Charles Richard Drew因为在第二次世界大战早年间指导第一个美国的大规模血库项目故这里形容词性物主代词修饰名词role。故用his。

3考查冠词这里用定冠词the特制第二次世界大战初期故这里用the。

4考查定语从句的用法。句意:大学毕业之后,Drew 去了蒙特利尔总医院在那里他和Doctor Beattie一起研究输血根据结构可知,这里构造非限制性定语从句,介词at后加关系代词指代蒙特利尔总医院故用which。

5考查不定式他意识到找到储血的方法非常重要。way to do sth做某事的方法,故这里用to store。

6考查副词。句意:这样的话,当需要时就可以被立刻使用。故用副词immediately。

7考查时态。句意后来,Drew研发了长期保存血浆的技术根据语境可知这里是过去的事实,故用developed。

8考查主语。句意: Drew的这个重要发现在第二次世界大战期间拯救了无数的生命。这里用名词作主语,故用discovery。

9考查介词。句意他坚持忽视献血者和输血者的种族背景意味着非白人士兵不会再流血致死。Insist后接介词on。

10考查现在分词。句意:他坚持忽视献血者和输血者的种族背景意味着非白人士兵不会再等待同种族的捐赠者献血时流血致死从句省略主语non-white soldiers,动词和逻辑主语之间是主动关系,故用现在分词waiting。

【题目】Science and technology have advanced at such a rate that cloning has now become a reality. The possibility of cloning humans is a serious issue(争论点) and raises ethical(伦理的) questions. In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be approached with caution and carefully monitored by governments.

Research into cloning and stem(严格的) cell production is primarily aimed at finding new treatments for currently incurable illnesses. While this would improve the quality of life for many, not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned humans and on the rest of the world. Furthermore, it is thought that a cloned human would be unlikely to survive birth and would suffer from complications(并发症) resulting from malformed(畸形) organs .

There are also serious ethical issues in danger. In essence(在本质上), those who are against cloning would argue that scientists have no right to play God and to interfere(干扰)with natural processes. Producing embryos for the purpose of harvesting stem cells for research presents important questions about the nature and status of the embryo being produced. It may also make us question whether throwing it away after use reduces the value we place on human life.

In conclusion, I do not agree that research into cloning using human embryos should continue. This is not only because it may reduce the value we place on human life, but also because not enough is known about the effects. However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it.

1What is the writer’s general opinion on cloning?

A. It is useful in every area of research.

B. It needs to be carefully controlled by governments.

A. reach a high level or amount B. move forward

C. come near D. deal with

3The writer’s main reason against cloning is that ______.

A. not enough is known about the effects of cloning

B. a cloned human would be likely to die of malformed organs

C. cloning has negative physical and psychological effects on clones

D. it would affect the quality of life for many

4In the last paragraph, the writer thinks governments should______

A. not put human life at risk

B. support all forms of research into stern cell production

C. not support any form of research into stern cell production

D. support research into stern cell production harmless to humans life

【题目】Suddenly another thought went through Kate’s mind like an electric shock. An express train was due to go past about thirty minutes later. If it were not stopped, that long train, full of passengers, would fall into the stream. “Someone must go to the station and warn the station-master,” Kate thought. But who was to go? She would have to go herself. There was no one else.

In wind and rain she started on her difficult way. Soon she was at the bridge that crossed the Des Moines River, a bridge also built of wood, just like the bridge across Honey Creek. The storm had not washed this away, but there was no footpath across it. She would have to cross it by stepping from sleeper (枕木)to sleeper. With great care she began the dangerous crossing, sometimes on her hands and knees, hardly daring to look down between the sleepers into the wild flood waters below. If she should slip, she would fall between the sleepers, into the rapidly flowing stream.

At last -- she never knew how long it had taken her- - she felt solid ground under her feet. But there was no time to rest. She still had to run more than half a mile and had only a few minutes left. Unless she reached the station before the express did, many, many lives would be lost.

She did reach the station just as the train came into sight. Fortunately the station-master was standing outside. “The bridge is down! Stop the train! Oh, please stop it!” Kate shouted breathlessly.

The station-master went pale. He rushed into the station building and came back with a signal light. He waved the red light as the train came into the station. It was not a second too early.

1What did Kate decide to do?

A. Stop the express train. B. Check the signal light.

C. Meet the passengers. D. Visit the station-master

2Which of the following words best describes Kate’s journey

A. Fruitless. B. Boring.

C. Well-planned. D. Risky.

3Why did the station-master turn pale?

A. He suddenly fell ill. B. He realized the danger.

C. He discovered his mistake. D. He became over-excited.
