Gene technology to benefit people

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors 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, 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 and clever children. Some families, with the English imperial family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist 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 in 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 way. Of course, the governments must take care to control gene technology.    

What does "these two killers" in the second paragraph refer to? 

A. gene technology and another treatment of the two diseases.

B. The two murderers who killed the cloned baby

C. The two diseases of cancer and heart disease

D. Hereditary diseases and cancer

What's the main idea of the third paragraph?

A. How gene technology can be applied in the field of treating hereditary diseases.

B. Gene technology can be used to clone human babies.

C. Gene technology can help people to give birth of a baby.

D. Gene technology can help the English imperial family out

In what way gene technology can help to treat hereditary diseases?

A. Using gene technology, people with hereditary diseases can have more living days.

B. Using gene technology, scientist finds the wrong gene and corrects it.

C. Using gene technology, human babies can be cloned.

D. Doctors can cure cancer and heart disease with the help of gene technology.

What is the main purpose of writing this passage?

A. Expressing the writer's idea that gene technology will benefit people

B. Telling people the advantages of gene technology

C. Telling the readers that gene technology will not benefit people

D. Explaining that gene technology will also do harm to the humanity

Happiness and sadness are states of being states of being that define the way we view the world. It is often said that some people by nature have a sunny character. Now scientists may have discovered why.
Some people may be hard-wired for happiness, while others are genetically negative, as
scientists have suggested in a study published in late February, in a British journal Proceedings of the Royal Society B.
Earlier research had already established that the gene known as 5-HTTLPR plays a key role in
determining how the neurotransmitter (神经传递素) serotonin (血清素) works within the brain. Serotonin, a hormone (荷尔蒙), passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant (抗抑郁) drugs regulate serotonin levels. Scientists had also identified three variants of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers.
Researchers from the University of Essex in Britain, led by Elaine Fox, showed participants a
series of images. The images were divided into three kinds: negative ones aimed at inspiring fear or stress such as a spider or person about to commit suicide, pleasant ones and neutral ones.
“The participants who had the long variant of the 5-HTTLPR gene showed a clear dislike of negative material alongside a careful attention for positive material,” the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction.
In January, the Australian government organized "happiness workshops", teaching government
staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff. Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.
67．Form the third paragraph, we know that         .
A．affected by 5-HTTLPR, the neurotransmitter serotonin works within the blood
B．there are 5 variants of 5-HTTLPR genes which control people’s moods
C．how the neurotransmitter serotonin works is greatly determined by 5-HTTLPR
D．5-HTTLPR receives chemical messages from verve cells
68．What does “It” in the sentence “It has been closely linked to mood.” in the 3rd paragraph refer to?
A．Serotonin.          B．A nerve cell.        C．5-HTTLPR.         D．The brain.
69．If a person had the long variant of 5-HTTLPR, he or she would probably         .
A．like the images of spiders                     B．prefer the images of crocodiles
C．enjoy an image of green tress                D．suffer from depression very often
70．What can we infer from the passage?
A．People’s moods can change a little bit under the influence of certain drugs.
B．Researchers showed participants of the research two kinds of images.
C．A person possesses one long and one short variant of 5-HTTLPR at the same time.
D．The author firmly believes that “happiness workshops” will not change people’s moods.

The Olympic Games are seen as the greatest test of an athlete’s ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began.
In the early years, athletes ate mushrooms(蘑菇)and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping(服用兴奋剂).
Just last month, Britain’s top sprinter(赛跑选手) Dwain Chambers and several American athletes tested positive(呈阳性)for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how to test for it.
“We’re like cops(警察)chasing criminals—athletes are always adapting and looking for areas we haven’t investigated,” said Jacquew de Ceaurriz, a French anti-doping expert.
Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson.
He broke the 100 meters world record in winning gold at the 1988 Seoul(汉城)Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action—only to be found positive again and banned forever.
China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes—seven of them swimmers—tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again.
Experts are also worried that doping can damage a person’s health. It is believed to increase the risk of liver and kidney(肝肾)diseases, and women may experience reproductive(生育) problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene(基因)technology.
“For the moment, genetic doping does not exist,” said de Ceaurriz. “Even in 10 or 15 years it will not be done easily—the scientific community(界)will not let it happen.”
(  ) 60. Which of the following is not the way that some athletes cheat to their better sports achievements?
A.Eating mushrooms.        B Taking drug THG.
C. Taking genetic doping.       D. Eating plant seeds.
(  ) 61. How many countries are mentioned in the passage in which there were athletes doping?
A. Two.                 B. Four.                C. Sic.                  D. Eight.
(  ) 62. We can infer from the passage that ____.
A.scientists get a lot of information about drugs before the athletes take doping
B.taking doping will never happen again because of the serious test
C.few athletes used drug cheats before the first drugs test was carried out at the 1968 Olympics
D.problems with drug cheats are still serious though they are severely tested
(  ) 63. Which statement of the following is true?
A.Many police are sent to chase criminals of taking doping during the Olympic Games.
B.The drug test was carried out until the 1968 Olympics.
C.There is the possibility that women athletes taking doping will give no birth to a child.
D.Ben Johnson was banned from sports forever for being tested positive for drug use at the 1988 Seoul Olympics.

Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因） is complete．Couple of years ago, this seems an impossible task for scientist to accomplish．All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away．Human cloning has always been a topic of argument, in terms of morality or religion．

         Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning．If the clone was free of genetic limitations．then the other clone would be as well．The latter could foe inserted in the woman and allowed to ripen to term．Moreover, cloning would enable women, who can't get pregnant, to have children of their own．

         Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs．This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single （or more） organ （s）．It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists．

         Arguments against cloning are also on a perfectly practical side．Primarily, I believe that cloning would step in the normal "cycle" of life．There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment．Life processes failing to do so might result in untimely disappearance．Furthermore, cloning would make the uniqueness that each one of us possesses disappear．Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society．

         Scientists haven't 100 per cent．guaranteed that the first cloned humans will be normal．Thus this could result in introduction of additional limitations in the human "gene-pool"．

         Regarding such arguable topics in "black or white" approach seems very innocent to me personally．We should rather try to look at all "shades" of it．I believe that cloning is only legal if its purpose is for cloning organs; not humans．Then we could regard this as for "saving life" instead of "creating life"．I believe cloning humans is morally and socially unacceptable．

1.Which of the following is true according to the passage?

A．Genetic limitation will be beneficial for some women

B．A large number of genes will prevent us from developing

C．Prohibition of cloning might limit the freedom of scientists

D．First cloned humans might be normal according to scientists

2.What's the author's opinion on cloning?

A．Cloning should be entirely banned．

B．Cloning should be used in creating life．

C．Cloning will take away the right to reproduce．

D．Cloning is acceptable if it is used for cloning organs．

3.Where can you read this article?

A．In a story book

B．In a magazine

C．In a science fiction

D．In a brochure

4.Which of the following shows the structure of the passage?
