第二部分 阅读理解 (共20小题；每小题2分，满分40分)
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
A
An extinct mountain goat that was once common in the Pyrenees briefly became the first animal to be brought back from extinction, as researchers used frozen DNA to produce a clone. But the newborn kid died within minutes of birth due to breathing difficulties, signaling that the Jurassic Park dream of resurrecting extinct species is still some way off.
The Pyrenean ibex, or bucardo, is a subspecies of the Spanish ibex that is believed to have died out completely in 2000. Before the death of the last known individual (a 13yearold female known as Celia), biologists captured her and took cells from her skin and ears, which were frozen in liquid nitrogen(氮). An earlier cloning attempt using the skin cells failed during gestation. But the latest attempt involved the creation of 439 ibexgoat hybrid cloned embryos(胚胎). Of these cloned embryos,57 were transferred into surrogate mothers and seven resulted in pregnancies, but only one goat gave birth and the newborn clone died after seven minutes as a result of lung desease.
Researchers say that other cloned animals, including sheep, have been born with similar lung defects, but they say that overall the experiment was a major step forward in the effort to bring the ibex back to its mountain home. Says lead researcher Jose Folch: “The delivered kid was genetically identical to the bucardo. In species such as bucardo, cloning is the only possibility to avoid its complete disappearance”．
The failure to produce a viable clone from DNA that was frozen only a decade ago illustrates the difficulty researchers would face in trying to bring back species that have been extinct for decades, centuries, millennia, or epochs. Researchers have floated the idea of bringing
back the Tasmanian Tiger, which went extinct in 1936, and others hope that woolly mammoths preserved in permafrost could one day be resurrected.Those efforts are still largely hypothetical. There are, however, other serious proposals for cloning endangered animals, such as the giant panda, the African bongo antelope, the Sumatran tiger and the pygmy hippo. The method's advocates believe it offers hope of preserving the genetic diversity of these animals before they die out.
【语篇解读】 科学家通过冻结的DNA成功地克隆了一只比利牛斯野生山羊。这
种野生山羊在2000年就已经灭绝了。
36．What do we know about the cloned ibex?

37．Jose Folch would agree that cloning________.
A．is not suitable and should be banned
B．requires immediate attention
C．should be carried out cautiously
D．may help prevent animal extinctions
解析 细节理解题。根据第三段cloning is the only possibility to avoid its complete disappearance.可知， Jose Folch认为克隆有可能避免物种灭绝。
答案 D
38．We can conclude from the passage that________.
A．cloning has developed quickly in developed countries
B．no more animals will die out in the future
C．cloning makes it possible to preserve endangered species
D．cloning seldom results in physical problems for animals
解析 推理判断题。根据最后一段Supporters believe cloning provides hope of keeping these endangered animals alive before they die out.可以推断，运用克隆技术来挽救濒危动物是有希望的。
答案 C
39．What's the best title for this passage?
A．Great advancement in cloning goats
B．Difficulties in saving extinct animals
C．Public concerns about cloning
D．Cloning brought back an extinct species for a while

答案 D
B
We each have a unique genetic(基因的，遗传的) makeup. Every cell of your body has the same set of about 100,000 separate genes made of DNA.These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion combinations of DNA which come from the random mixing of your parents' genes. Except for identical twins(同卵双胞胎), no one has the same combination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make.
But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births—some are identical and others are nonidentical twins. Identical twins are special because they share exactly the same genes and often the same environment. Nonidentical twins are more like ordinary brothers and sisters.
Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like shortsightedness, are mostly genetic.But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Nonidentical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than nonidentical twins.
Scientists are trying to identify the different genes that influence our behaviour. Some people are thrillseekers and get into risktaking and adventurous activities.They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.
We could ask，“Are our lives determined by our genes or our upbringing？” Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.

答案 C
C
Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however,
when they realize that the cloned creatures are smarter and more dangerous than expected.That's nothing more than a fiction.
But could we really clone endangered animals?
To date, the most successful attempt to do so was the cloning of a gaur, a rare oxlike animal from southeast Asia.Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.
Next, could we really clone extinct animals?
In theory? Yes. To do this, you need a wellkept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate_mother.
In reality? Probably not. On the one hand, it's not likely that extinct animals' DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly wellpreserved DNA.On the other hand, for example, a gaur can have a cow as a_surrogate_mother,_definitely not a monkey. But what about an extinct animals as unique as the panda? What species could possibly serve as a surrogate mother?
Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today's world.Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.
【语篇解读】 我们可以克隆濒临灭绝的动物吗？我们能克隆已经灭绝的动物吗？

答案 D
D
The United States government wants to know what the public thinks about its findings on the safety of cloned animals.
The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An F．D.A.official called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually(有性繁殖), the agency says, their offspring(后代) are safe to eat as well. But research on cloned sheep is limited. So the F．D.A.proposes that sheep clones not be used for human food.
The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the public will have ninety days to comment on three proposed documents. On December 28th the F．D.A.released a long report, called a draft risk assessment, along with two policy documents.
The agency says it must receive comments by April second. The F．D.A.seemed ready to act several
years ago, but an advisory committee called for more research.
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.
Clones are still rare. They cost a lot and are difficult to produce.
The F．D.A.says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.
Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning.
Cloning differs from genetic engineering. A cell taken from a socalled donor animals is grown into an embryo(胚胎)in the laboratory. Next, the embryo is placed into the uterus(子宫)of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.

Good morning.Well，this is not how I expected to wake up this morning.After I received the news，Malia walked in and said，“Daddy，you won the Nobel Peace Prize，and it is Bo's birthday！” And then Sasha added，“Plus，we have a threeday weekend coming up.” So it's good to have kids to keep things in perspective.
I am both surprised and deeply humbled by the decision of the Nobel Committee.Let me be clear：I do not view it as a recognition of my own accomplishments，but rather as an affirmation of American leadership on behalf of aspirations held by people in all nations.
To be honest，I do not feel that I deserve to be in the company of so many of the transformative figures who've been honored by this prize—men and women who've inspired me and inspired the entire world through their courageous pursuit of peace.
But I also know that this prize reflects the kind of world that those men and women，and all Americans，want to build—a world that gives life to the promise of our founding documents.And I know that throughout history，the Nobel Peace Prize has not just been used to honor specific achievement；it's also been used as a means to give momentum to a set of causes.And that is why I will accept this award as a call to action—a call for all nations to confront the common challenges of the 21st century.
These challenges can't be met by any one leader or any one nation.And that's why my administration has worked to establish a new era of engagement in which all nations must take responsibility for the world we seek.We cannot tolerate a world in which nuclear weapons spread to more nations and in which the terror of a nuclear holocaust endangers more people.And that's why we've begun to take concrete steps to pursue a world without nuclear weapons，because all nations have the right to pursue peaceful nuclear power，but all nations have the responsibility to demonstrate their peaceful intentions.
We cannot accept the growing threat posed by climate change，which could forever damage the world that we pass on to our children—sowing conflict and famine；destroying coastlines and emptying cities.And that's why all nations must now accept their share of responsibility for transforming the way that we use energy.We can't allow the differences between peoples to define the way that we see one another，and that's why we must pursue a new beginning among people of different faiths and races and religions；one based upon mutual interest and mutual respect.
And we must all do our part to resolve those conflicts that have caused so much pain and hardship over so many years，and that effort must include an unwavering commitment that finally realizes the rights of all Israelis and Palestinians to live in peace and security in nations of their own.
52．Which statement is TRUE according to the speech in part one?
A．President Obama got up as usual on the morning of his winning the Nobel Peace Prize.
B．President Obama was pleased at his winning the Nobel Peace Prize.
C．President Obama thought he deserved the Nobel Peace Prize.
D．President Obama's kids were excited at the Nobel Peace Prize.

答案 D
53．According to Obama's point，all nations confront the common challenges of the 21st century.Which one is NOT included?

54．The growing threat—climate change could cause much damage.Which one is NOT caused by it?
A．Increasing the global financial crisis.
B．Sowing conflict and famine.
C．Destroying coastlines.
D．Emptying cities.
解析 细节理解题。从倒数第二段直接可判断B、C、D三项是气候变化带来的影响，而A项并未涉及。
答案 A
55．We can infer from the last paragraph that ________ is true.
A．all nations have united to resolve the conflicts between countries
B．all nations have had an unwavering commitment to resolve the conflicts
C．all Israelis and Palestinians now live in peace and security in nations of their own
D．all Israelis and Palestinians are now in conflict with each other
解析 从最后一段的后半句“……最终实现所有以色列人和巴勒斯坦人在他们自己的国家里和平安全地生活的权利。”可推断出答案。
答案 D

As a Senior Three student，time seems very limited.As a result，more and more students try to study from early morning till late afternoon，even during the tenminute break.In my opinion，to take a tenminute break between classes is definitely necessary.Otherwise we will feel tired both physically and mentally.
During the tenminute break we had better do something to get rid of tiredness.What we need is to have a real rest，instead of getting more tired.So doing nothing tiring is really good for us.
My tenminute break is always wonderful.Sometimes I take some simple exercise.Sometimes I have a small talk with my classmates or just take a walk outside.Besides，I like looking at green trees out of the window，doing nothing.This will help to relax myself.When the next class begins I feel refreshed again.
