A recent announcement by scientists that they have successfully cloned the first human embryo has caused much debate and has shocked many people around the world. On the one hand,some scientists point out that if you clone an embryo,you can produce valuable tissues(組織)and organs that could be used to save human lives. On the other hand,many people,including some scientists, disagree and fear that if mankind interferes with(干涉)nature in this way,they may be on their way to producing a real-life Frankenstein’s monster.

    Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly the sheep. She was born in 1996 and died in early 2003,at a much younger age than normal. When she was born,many people were angry because they thought cloning would create more disease in the animal world. However,in general the scientists were praised for their wonderful scientific breakthrough.

    The Scottish scientist who created Dolly,Ian Wilmut,is shocked that some scientists are now considering cloning human beings. Although he researches cloning,his intention has never been to create copies of humans. Instead,he thinks research efforts should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However,some people consider that cloning human embryos with the intention of destroying them shows no respect for human life.

    While cloning human embryos is illegal in many countries,some scientists are already pushing ahead with research so as to deliver a cloned human baby. Severino Antinori,an Italian doctor,is one of the leaders in this kind of research. He has declared that he wants to be the first to clone a human being.

    In China,scientists have focused their efforts on cloning animals,as well as stern cells to be used in medical research. China has succeeded in producing clones of cows and goats,and continues to research ways in which cloning can benefit mankind.

51. Which of the following statements about cloning is TRUE according to the passage?

A. Cloning technology can only be applied to animals.

B. A cloned animal can live longer than a normal one.

C. People all over the world are happy about the birth of Dolly.

D. Cloning can produce valuable tissues and organs to cure human diseases.

52. The reasons why people are anti-cloning include the following EXCEPT that_______.

A. cloning may produce a real-life Frankenstein’s monster

B. cloning might create more disease in the animal world

C. cloning can’t help those who want to clone their dead children

D. cloning human embryos shows no respect for human life

53. Who is in favor of cloning human beings?

A. Ian Wilmut.        B. Severino Antinori.

C. The author.        D. The Chinese scientists.

54. What can be inferred from the last two paragraphs?

A. If we interfere with nature, we will change the world to be what we want.

B. It is impossible to clone babies for women who cannot have ones.

C. Cloning human beings is illegal in many countries,so no scientists want to do so.

D. Whether cloning human embryos is legal or not remains a matter of debate.

51. 【解析】選D。細(xì)節(jié)理解題。根據(jù)第一段第二句可知D項(xiàng)正確。根據(jù)第二段首句可知A項(xiàng)錯(cuò)誤;從第二段Dolly的例子可知克隆的動(dòng)物不如正常的動(dòng)物壽命長(zhǎng),故B項(xiàng)錯(cuò)誤;C項(xiàng)與原文第二段的第四句話相悖。

52. 【解析】選C。細(xì)節(jié)理解題。文中前三段提到人們反對(duì)克隆技術(shù)的原因包括A, B和D項(xiàng)。文中未提及C項(xiàng)。

53. 【解析】選B。推理判斷題。根據(jù)文章倒數(shù)第二段第二句可知,Severino Antinori也在從事克隆人類的研究,這說明他支持克隆人。

54. 【解析】選D。推理判斷題。通過最后兩段可以推斷出,雖然克隆人在很多國家還不被認(rèn)可,但是有些科學(xué)家已經(jīng)開始了這方面的研究。對(duì)于克隆人是否合法現(xiàn)在還是一個(gè)存在爭(zhēng)議的問題。

  In the United States more than 80 colleges now accept just only women.Most of them were founded in the 19th century.They were set up to   1   women the education they could not get anywhere else.At that time   2   of the universities and colleges   3   only men.In the past 20 years many young women have   4   to study at colleges that accept both men and women.As a   5  , some women's colleges decided to accept men students, too.Others still refused to change.Now the women's colleges are   6   again.

  The president of Trinity College in Washington D.C said by the end of the 1980s women had come to   7   that studying at the same colleges with men and women did not mean   8   had the same chance to   9  .The president of Smith College in Massachusette said “A women's college   10   women to choose classes and activities   11  .For example, if a woman student wants to learn maths, she will be given the chance.So the percentage of students who like to study maths in a women's college is   12   than that in a college with men and women.”

  Experts say men students in the United States   13   have enough courage to speak in class.  14  , women students can't.In a women's college, women feel free to say   15   they want to.According to a report, women colleges also   16   leadership ability in many fields.At a women college, every   17   office is held by women.Recent studies   18   that this leadership continues after   19  .The studies also prove that it is easier for the American women who went to women's college to   20   successful jobs later in life.Maybe that is why this kind of college is liked by people now.

According to a recent report, some once-hot majors like English, Computer and Law for Chinese students entering college have now fallen out of favor. The reason is that more graduates studying in those fields end up    1  .
This year, a sample of 500,000 college    2   from 2009 were surveyed and 220,000 questionnaires were received back for the 2010 report. Among the   3   
majors, Law graduates had the most difficulty finding jobs, with the   4   
unemployment rate(比率) of 17.7% of all the majors in 2009. English majors had the highest    5   of the unemployed for three years, with 15,700 graduates still out of work.
“Such majors as Computer, English and Law were the most    6   ones for Beijing students entering universities in 2005, but now these graduates are in a tight corner,” said Ba ran, a senior counselor(顧問)at a well-known company. Ba said that the expansion(擴(kuò)大)of college enrollment(注冊(cè))for those hot majors five years ago has    7   an over-supply in the market, making it harder for those graduates to find jobs.
On the other side, engineering graduates majoring in Geological Engineering, Ship and Marine Engineering are    8   most in the job market. Engineering majors are more practical in professional skills and work experience, which are favored by many    9  . The graduates are thus armed with a competitive    10   in the cruel job market.

For some colleges and provinces with   14   employment rates, the report advised a(n)   15   in enrollment numbers or even a temporary (暫時(shí)的) stop in enrolling students.

第三部分:閱讀理解(共兩節(jié),40 分)
第一節(jié):(共15小題;每小題2分,共30分)
閱讀下列短文,從每題所給的A、B、C、D四個(gè)選項(xiàng)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
Shopping in the United States changes a lot.About ninety years ago most people shopped in small stores that were owned by one person or a family.Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week.
Then about sixty years ago, supermarkets were born.In a supermarket, people could get all the different kinds of food they needed without going to different stores.
The next big change in shopping in the United States was the shopping mall.A shopping mall is a group of stores under one roof.Because malls allowed people to shop without worrying about the weather, they soon became very popular.The mall became a place for people to socialize in addition to shopping.If you walk through a mall, you will see older people sitting, chatting and drinking coffee.Malls are places for teenagers to hang out.Many teens will often just "go to the mall" and spend time with their friends.
The recent change in American shopping was the superstore.Large chain stores such as Wal-Mart, Office Depot and Toys "R" Us have been built all across the United States.Because they are so large, they can buy goods at a great discount and sell them much cheaper than smaller stores.
Sometimes, when they are built near small towns, many of the small town stores have to close.They just cannot compete with their giant neighbors.
And now, online shopping is becoming more and more popular all over the States.People are too busy to go to the physical stores, so they go shopping over the Internet.Online shopping has lots of advantages.For instance, online stores are usually available 24 hours a day.Searching or browsing online shops can be faster than browsing the physical stores.While, online shopping also has its disadvantages.People are at higher risk of being cheated on the part of the merchant than in a physical store.And privacy of personal information may be let out.
56.Which of the following shows the right order of shopping development in the United States?
①small stores  ②superstores   ③shopping malls    ④shopping online
⑤supermarkets
A.①②③④⑤             B.①⑤②③④
C.①⑤③②④          D.②③④①⑤
57.Which is the place for people to spend time with others according to the passage?
A.Shopping malls.           B.Small stores.      
C.Supermarkets.          D.Superstores.
58.Why can the superstores sell products at much lower prices?
A.Because they are built near small towns.
B.Because they are across the United States.
C.Because they sell all kinds of products people need.
D.Because they can buy goods at a reduction in the price.
59.What's the disadvantage of online shopping according to the passage?
A.Wasting time.         B.Leaking personal information.
C.Fixed prices.        D.No chance to do physical activities

As I was reading a recent story in Slate on 20-somethings complaining about how the economy was ruining their life plans, I couldn’t help but think the 20-somethings sounded like a bunch of spoiled children who grew up expecting everything to be easy for them.As a 20-something myself, I certainly share their disappointment: my husband and I probably won’t be able to buy a house until we’re in our 40s, and we too are burdened by student loans(貸款).But why should it be any different? Being young persons in America, shouldn’t they take up all of the challenges and opportunities that this country offers?

Consider some of these views shared in the Slate story: Jennifer, 29, owner of a two-bedroom apartment with her husband, worries that she won’t be able to have children for at least a decade because they can’t afford to buy a house yet.

I read that, and I thought, what planet is she living on where you need to own a house in order to have kids? Has she ever visited a developing country, or even downtown areas in this one? Home ownership is a luxury(奢華), not a fertility requirement.

A 26-year-old in the story despairs(絕望) that he can’t afford to get a Ph.D.in literature.Well, that sounds a bit like expressing disappointment that no one will pay you to write poetry on the beach in Thailand for five years.

Yes, it’s sad that these young people feel so lost.But I think the problem is their extremely high expectations, not economic reality.Beth Kobliner, author of Get a Financial Life: Personal Finance in Your Twenties and Thirties, says that she thinks people’s expectations are slowly adjusting, but today’s 20-somethings grew up at a time when everyone’s wealth appeared to be expanding.Their parents probably saw their home values rise along with their investments.“So you have people who have grown up in an environment where people had great expectations of what living well means,” says Kobliner.

This recession(衰退) will certainly play a role in forcing those expectations into more realistic group.In the meantime, it seems a lot better for our mental health to focus on being grateful-for our one-bedroom apartments, for living in modern cities, or perhaps just for being able to eat three meals a day-than on longing for some kind of luxury life.

1.What makes the author think the 20-somethings sound like a bunch of spoiled children?

A.They expect everything to be easy for them.

B.They complain that the economy is spoiling their life plans.

C.They are reluctant to face all of the challenges.

D.They are burdened by student loans.

2.The underlined word “fertility” in Paragraph 3 probably means        

A.baby production                                  B.pleasant

C.baby comfort                                      D.essential

3.What’s the author’s attitude towards the 20-somthings with high expectation in Paragraph 5?

A.Intolerant.         B.Negative.          C.Unbelieving.      D.Understanding.

4.What is the best title for this passage?

A.How Young People Afford to Continue Their Study

B.Why Young People Can’t Afford to Buy a House

C.When Young People’s High Hopes Create Despair

 D.What the 20-somethings’ High Expectations Are
