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(道德) 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 be 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% 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.
Which of the following is true according to the passage?

A．Genetic limitations will be beneficial for some women.

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

C．First cloned humans might be normal according to scientists.

D．Forbidding cloning might limit the freedom of scientists.

What’s the author’s opinion on cloning?

A．It should be entirely banned.	B．It is acceptable if it is used for cloning organs.
C．It will take away the right to reproduce.	D．It should be used in creating life.

Where can you read this article?

A．In a story book.	B．In a magazine.
C．In a science fiction.	D．In a novel.

Which of the following shows the structure of the passage(1—6 refer to paragraph 1—6)?

Educating girls quite possibly produces a higher rate of return than any other investment(投
资)available in the developing world．Women’s education may be an unusual field for experts On economy(经济)，but improving women’s contribution to development is actually as much all economic as a social business．And economics provides an explanation for why so many girls are
deprived of an education．
Parents in low-income countries fail to invest in their daughters because they do not expect them to make all economic contribution to the family：girls grow up only to marry into somebody
else’s family and bear children．Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school．Ignoring women’s education is therefore in a bad circle．
An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices．She is likely to have fewer but healthier children and can insist on the development of all her children, making sure that her daughters are given a fair chance．The education of her daughters then makes it much more likely that the next generation of girls，as well as of boys，will be educated and healthy．The bad circle is thus changed into a good
circle．
Educating women has great social benefits and great economic advantages as well．Most obviously, there is the direct effect of education on the wages of female workers．Wages rise by 10 to 20 per cent for each additional year of schooling．Such big returns are impressive by the standard of other available investments，but they are just the beginning．Educating women also has a significant effect on health practices, including family planning．
63．The author argues that educating girls in developing countries is          ．
A．troublesome                  B．labor-saving          C．rewarding         D．expensive

A. women care much more about education
B. girls can gain equal access to education
C. a family has fewer but healthier children
D. parents can afford their daughters' education
65．What does the underlined phrase“deprived of”mean in Paragraph One?
A．supplied with         B． included in               C．kept away from    D．devoted to
66．The passage mainly discusses          .
A. unequal treatment of boys and girls in developing countries

sing along with．When I went to watch Beijing Guo’an last season, I could join in one chant

didn't have to be gifted to work out what that meant.
At the World Cup，the first songs you’ll hear at matches will he the national anthems．Fans and players join together to sing the anthems before each match, and it is considered a mark of
respect that the opposite remains silent while each team's an them is being sung．

Dear Economist,
My newly-wedded wife and I are deeply in love. There is, however, one issue that threatens the happiness of our marriage. I absolutely insist on shopping at Walmart. My wife, meanwhile, would rather avoid Walmart at all costs.
　　I have recently tried to convince her that not only does Walmart offer the lowest prices known to man, but that the chain is also a force for good―lower prices mean better standards of living for all consumers, increased global trade means a tighter-knit(紧密团结的) international community, and efficient operations translate into higher productivity growth for the economy. My wife complains about poor labour policies, the “fact” that Walmart squeezes suppliers, and that it puts local shops out of business.
　　Who is right? Will our marriage survive?
　　 Brian Gee
Dear Brian,
I have to agree with you about Walmart. Jason Furman, then an economist at New York University, now an adviser to President Obama, famously argued in 2005 that Walmart was unwittingly (不知不觉地) a progressive success story. The chain’s prices don’t much affect me (I prefer Whole Foods) but Furman estimated that they benefited low-and-middle-income Americans to the sum of around $250 billion a year.
　　Walmart does not pay much, so it may depress wages. Then again, it may increase wages by offering jobs to the otherwise-unemployed. Either way, the benefits of low prices to Walmart shoppers far outweigh any seemingly reasonable costs to Walmart employees. And while it is true that Walmart employees tend to be poor, the same is true of Walmart shoppers.
　　Armed with this information you can face your wife with confidence. You are sure to win the conversation. The divorce is likely to be more argued.
Economist
68. What concerns Brian Gee so much that he wrote the letter?
A. His wife refuses to shop at Walmart.
B. They are faced with a divorce.
C. They can’t afford the costs of shopping at Walmart.
D. They are in conflict about shopping at Walmart.
69. Brian Gee’s wife tends to hold the opinion that _________.
A. it is wrong for Walmart to depress its employees’ wages
B. consumers’ lives have improved thanks to Walmart
C. Walmart’s business operation increases productivity in economy
D. Walmart’s business increases global trade
70. What can be inferred from the reply letter?
A. Some employees accept the low pay to keep the job.
B. Walmart appeals to only poor consumers and poor employees.
C. Employees suffer from Walmart’s low prices more than consumers.
D. Jason Furman, a New York University economist, spoke highly of Walmart.

To be able to motivate oneself, or self-motivate, occurs when a person has the willingness to do something and is internally(内在地) motivated to do it.
Sometimes it’s very difficult to get ourselves moving. The natural tendency is to postpone. Life just seems to get in the way! There is a job to go to, groceries to do, television to watch—whoops! I guess we get pretty good at finding excuses to escape getting started on goals like an exercise routine or reading a new book. The fact is that we are creatures of routine and habit. So what can we do to motivate ourselves to accomplish our goals?
Here are some tips on how to get moving:
l Decide what you want. It’s hard to motivate an aimless mind. Set a goal and decide how you are going to go about it. Then break it down into smaller sections so it’s easier to handle and less overwhelming.（势不可挡）
l Keep track of your progress. Keep a log or journal where you can measure how much you have accomplished. Looking at it can also motivate you to keep pushing ahead.
l Post motivating pictures or slogans within your sight. It is always inspiring to see pictures of people who have accomplished what you’re going for. It makes it attainable and realistic. Likewise, little slogans like “go for it” or “just do it” can give you the little support you need.
l Sometimes we forget what we set out to do and a little reminder is all we need to be revitalized (激活) and focus on the end result. If you remind yourself to go for the desired promotion, it will re-establish why you are doing what you’re doing.
l Make it a habit. Once you have accomplished your objective, e.g. becoming an early riser, keep it up so that it’s second nature to you and you don’t have to think about it anymore.
64. According to the author, some people fail to achieve their goals because ________.
A. they don’t have enough desire
B. their life is filled with routine work
C. they benefit from the force of habit
D. they naturally put off forming new habits
65. It can be inferred from the underlined sentence that ________.
A. self-motivation needs repeated self-reminding of one’s goal
B. in modern society people tend to become forgetful
C. when we forget our goal, our life becomes meaningless
D. we can achieve our goal only by focusing on the end result
66. To get moving on your goal, you can do the following EXCEPT ________.
A. keep a diary to clearly judge your distance to your goal
B. make self-improvement your second nature
C. forget your aim and revitalize yourself with slogans
D. support yourself by hanging inspiring pictures in your house
67. Which of the following is the best title for the passage?
A. Set Goals in Your Life                                          B. Get Yourself Motivated
C. Get into Good Habits                                          D. Do Not Postpone
