Sometimes it is a hot topic discussed by people.The greatest thing that gene technology can do is cure serious diseases that doct

2、ors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers.And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely,

3、 bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well.In addition, human life span(寿命) can be prolonged.Gene technology can help people to give birth to more healthy a

4、nd clever children.Some families, with the English imperial(皇家的) family being a good example, have hereditary diseases.

5、ene technology can solve this problem perfectly. Scientists just need to find the wrong gene and correct it, and a healthy child will be born.Some people are worrying that the gene research can be used to manufacture human beings in large quantities.In the past few years, scientists have succeeded i

6、n cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal ways. Of course, the government must take care to control gene technology.【解题导语】本文

In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, so

12、me used to smoke, and the rest were nonsmokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changeda number that is onethird of known human genes.According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the c

13、hanges when they were born, but most people get them in their daytoday lives while doing things like smoking.When you stop smoking, a lot of these genes will return to normal within five years.This means your body is trying to heal(治愈) itself of the harmful effects of smoking. But the changes in som

14、e of the genes stay for longer. They can stay for as long as 30 years. Its almost like leaving a footprint on wet cement(水泥)it will always be there, even when youve walked away and when the cement becomes dry.Although the study results may make people unhappy, there is a bright side:the findings cou

15、ld help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.【解题导语】新的调查研究发现,由于吸烟而引起的基因突变在戒烟后并不会马上消失,而是会在体内保留一段时间,这些基因突变大部分会在五年内恢复正常,但有一些甚至三十年都不会恢复。5The function of Paragraph 1 is to _Ashow the main idea of the passa

16、geBgive an exampleCmake an argumentDintroduce the topic of the passageD解析:篇章结构题。第一段提出了这样一个问题:“吸烟是有害的,但是只要你戒烟,一切都会恢复正常,对吗?”第二段给出了回答,接着下文便从一些调查研究的结果开始解释这个问题。文章围绕这一问题展开,所以第一段的作用是引出本文的主题。故选D。6Most genetic changes happen because of _Apeoples condition at birthBpeoples bad living habitsCenvironmental poll

17、utionDheart disease and cancerB解析:细节理解题。根据第三段第二句可知,一些人的基因突变是生下来就有的,但大部分人的基因突变是由于日复一日地做一些(有害身体的)事,比如吸烟,而积累下来的。故选B。7The underlined word “it” in Paragraph 5 refers to _Athe genetic changeBthe cementCthe harmful effectDthe footprintD解析:代词指代题。根据画线词所在句可知,这就像在水泥上留下的脚印即使你走开,即使水泥变干的时候,脚印将一直留在那里。故it指代“脚印”。8Wh
