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 clonc 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 peoplearound 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 reb pepole 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.Futhermore,cloning would make the uniqueness that each one of us possesses disapparance.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 percent. guaranteed that the first cloned 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.
67.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
68.What’s the author’s oponion 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
69.Where can you read this article?
A.In a story book
B.In a magazine
C.In a science fiction
D.In a brochure
70.Which of the following shows the structure of the passage

Many of the problems facing today’s world aren’t news to us. The environment is in dire need of help because it’s being damaged, hunger is widespread throughout the world, and workers in the Third World Countries are continuously being exploited. Therefore, individuals across the globe need to band(团结)together for a cause and use their collective efforts to make all the difference in the world.
For instance, one person recycling a can or a bottle doesn’t seem like much. But if every household in a given city was to recycle and conserve energy, that city could make a huge positive impact on environmental damage. Similarly, there are countless ways to help fight world hunger—whether it’s to donate money to a dedicated worldwide charity, donate canned goods to your local charity, or even make lifestyle changes like going vegetarian. World hunger is a massive problem—but it doesn’t mean individuals themselves can’t make a difference.
Worker exploitation is another huge problem. All across the world—particularly in the Third World Countries—workers are forced to labor long hours, with close to no pay. Yet these workers continue to show up to such a way of life, because they have no other options.
So, how can people like us help fight such a big problem? Simply raising awareness of the products you buy in stores—from clothing to food—is a massive start. For example, if you see two similar products side by side in a food shop, but one of them is labeled “fair trade”, you’ll know immediately that the workers who labored to produce that product were given a fair price for their goods. And true, fair trade products might cost a little bit more, but buying them is a significant start to help fight worker exploitation.
In short, each of us should be socially conscious to make a difference to widespread social problems.

LONDON, Feb. 18,2014(Xinhua News agency)—Britain will send experts to East China's Shanghai to learn from the city's experience in maths teaching in an attempt to raise the teaching standards.
British Education Minister Elizabeth Truss is to lead a delegation of experts on a fact-finding mission to Shanghai's schools next week to see how children there have become the best in the world at maths, to get a first-hand look at maths classes and teaching methods there, and particularly to investigate why the performance of almost all children in Shanghai is high, regardless of gender or income.
Britain was last year placed 50th out of 148 countries and regions in the World Economic Forum's competitiveness ranking in quality of maths and science education. Two years ago, Shanghai topped the 2012 international PISA tables for maths, while England was ranked in 26th place. The top five were all in Southeast Asia, with 15-year-olds in Shanghai judged to be three years ahead of their peers in maths.
The education department said: "England's performance in maths has lagged behind while other countries have improved and overtaken us, including Poland and Germany." Actually, it is the latest step in the government's drive to raise standards in maths, looking at what has made schools in the far East the most successful in the world in teaching the subject.
"Shanghai is the top-performing part of the world for maths—their children are streets ahead. Shanghai and Singapore have teaching practices and a positive mind that make the difference. They have a belief that diligence makes up for lack of ability," Truss said. "Our new curriculum has borrowed from theirs because we know it works—early learning of key arithmetic, and a focus on times tables and long division(长除法), for instance."
She was determined to change the situation as performance in maths is weakening the country's skills base and threatening the productivity and growth. The government is emphasizing maths because of the importance of good grades in the subject to young people competing for good jobs in a global labor market and to the economy more generally.
An education and skills survey released by the Confederation of British Industry last year showed that 30 percent of employers reported dissatisfaction with the standard of school and college leavers' numeracy. More than two-thirds of employers said they wanted both maths and science promoted more in schools.
Why does the British government send a delegation of experts to Shanghai?

A.To see how children from rich families have become the best at maths.
B.To investigate why the performance of almost all children in China is high.
C.To get a first-hand look at science classes and teaching methods there.
D.To raise the teaching standards in maths in Britain.

D.The students from Germany did better than the students from Poland.

A.Curriculum and teaching methods.
B.Teaching practices and a positive mind.
C.Early learning of key arithmetic and times tables.
D.A focus on times tables and long division.

How will students’ poor performance in maths affect the country?

For centuries, the body’s blood has been linked closely with the emotions. People who show no human emotions or feelings, are said to be cold-blooded killer. For example, the police are searching for a cold-blooded killer. He seems to kill for no reason, and no emotion, as if taking someone’s life as nothing.
Cold can affect other parts of the body. The expression “get cold feet” has nothing to do with cold or your feet. The expression means being afraid to do something you have decided to do. For example, you agree to be president of an organization. But then you learn that all the other officers have resigned, and all the work of the organization will be your responsibility. You are likely to get cold feet about being president when you understand the situation.
The expression “give someone the cold shoulder” probably comes from the physical act of turning your back toward someone, instead of speaking to him face to face. You may give a cold shoulder to a friend who has not kept a promise he made to you. Or, to someone who has lied about you to others.
A cold fish is not a fish. It is a person. But it is a person who is unfriendly, unemotional and shows no love or warmth. A cold fish does not offer much of himself to anyone. Someone who is a cold fish could be cold-hearted. Now a cold-hearted person is someone who has no sympathy. Several popular songs in recent years were about cold-hearted men or cold-hearted women who, without feelings, broke the hearts of their lovers.
Out in the cold means not getting something that everybody else got. A person might say that everybody but him got a pay raise--he was left out in the cold. And it is not a pleasant place to be.
There are _____ expressions related to cold that are mentioned in the passage.

A.3 B.4 C.6 D.7

When you refuse to speak to a man and treat him in a distant way, you may express by “_________”.

A.I give him the cold shoulder
B.I think he is a cold-blooded man
C.I think he is a cold fish
