A man living absolutely alone in a desert or forest is free from other people; but he is not absolutely free. His freedom is limited in several ways. Firstly, by the things around him, such as wild animals or cliffs. Secondly, by his own needs: he must have sleep, water, food and shelter from extreme heat or cold. Lastly, by his own nature as a man: disease may attack him, and death will certainly come to him sooner or later.
On the other hand, when men become organized into very large groups and civilization develops, it is possible to get freedom from hunger, thirst, cold, heat, and many diseases, so that each person can live a happier life than he could if he were living alone; but such a society can not work successfully unless the freedom of each human being is to some extent limited so that he is kept from hurting others. I am not free to kill others, nor to steal someone else’s property , nor to act in a way that does wrong against the moral sense of the society in which we live. I have to limit my own freedom myself so that others will not limit it too much: I agree to respect the rights of others, and in return they agree to respect mine.
The advantages of such an agreement are great: one can become a doctor knowing that others will grow food, make clothes and build a house for him, in return for the work he does to keep them healthy. If each man had to grow his own food, make his own clothes, build his own house and learn to be his own doctor, he would find it impossible to do any one of these jobs really well. By working together, we make it possible for society to provide us all with food , clothes, shelter and medical care, while leaving each of us with as much freedom as it can.

Should ecigarettes (electronic cigarettes) be a new choice for the smokers trying to get rid of the habit? Reactions from Americans are mixed. More than half of the people questioned in a survey think ecigarettes should be controlled by the US Food and Drug Administration，but 47 percent believe the ecigarettes should be available to the smokers who want to quit.
“In the hunt for a safer cigarette，ecigarettes are becoming a popular choice among those either trying to quit or looking to replace standard tobacco smoke with an alternative that manufacturers claim to be safer，” Zogby International，which conducted the survey，said in a statement.
About half of the 4,611 adults who took part in the survey had heard about ecigarettes，which are batterypowered，or rechargeable cigarettes that vaporize a liquid nicotine solution. They do not produce smoke but a water vapor without smell. Sold mostly on the Internet，ecigarettes were first made in China.
Last year the World Health Organization (WHO) warned against using ecigarettes，saying there was no evidence to prove they were safe or helped smokers break the habit. The WHO said people who smoke ecigarettes breathe in a fine fog of nicotine into the lungs.
Nearly a third of people questioned in the survey think that ecigarettes should be allowed in places where smoking is forbidden，because they don’t produce smoke，but 46 percent disagree. Men who were aware of the availability of ecigarettes were more likely than women to say they should be a choice available to smokers who want to quit. Young people，aged 18－29，and singles were the groups most open to trying ecigarettes. Smoking is the single largest cause of preventable death worldwide，according to the WHO.What can we learn from Paragraph 1?

When it comes to social behaviour，mammals are in a league of their own. Some birds may form pairs，or even cooperate to hunt，but the complexity (复杂性) of their relationships can hardly compare to those within a school of dolphins，a herd of elephants or a group of humans. What makes mammalian social groups different from a flock of starlings or a shoal of fish，is that in many cases the individuals could recognize each other. Although we may think that all elephants look pretty much the same，we can easily tell individuals of our own species apart and it has become clear through studies that the same is true of other species. Dolphins have their own signature whistles that act like “names”，and elephants can recognize and greet other individuals they have known but not seen for many years. This is something that only a few species of birds appear to be able to do.
Mammals in complex social groups not only recognize each other as individuals，but also they remember a lot of information about that individual. Social groups often rely on this memory—such as knowing who is dominant to whom，who is related to whom，and who has done what to whom in the past. It’s like remembering who you have lent money to or done a favour for，and who hasn’t repaid that money or has talked about you behind your back. You have to learn who to trust，who your friends are，and who to watch out for.
All this remembering goes on in a particular part of the brain called the neocortex (大脑皮层)．If you compare the size of a mammal’s social group with the size of this part of the brain，you will find they are remarkably closely related. This area seems to take a long time to develop fully and animals in which it is very large take a very long time to grow up to adulthood. During this time，the youngster has to learn all the rules of social behaviour in their group and to piece together all the relationships between the group members：Knowledge that will be needed to avoid getting into trouble.What is special about a mammalian social group according to the passage?
| A．All the individuals cooperate to hunt. |

Linda Evans was my best friend—like the sister I never had. We did everything together: piano lessons, movies, swimming, horseback riding.
When I was 13, my family moved away. Linda and I kept in touch through letters, and we saw each other on special time—like my wedding (婚礼) and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address (地址) Unknown. ” I had no idea how to find Linda.
Over the years, I missed Linda very much. I wanted to share happiness of my children and then grandchildren. And I needed to share my sadness when my brother and then mother died. There was an empty place in my heart that only a friend like Linda could fill.
One day I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman — Linda’s married name. “There must be thousands of Wagmans,” I thought, but J still wrote to her.
She called as soon as she got my letter. “Mrs Tobin!” she said excitedly, “Linda Evans Wagman is my mother. ”
Minutes later I heard a voice that I knew very much, even after 40 years, laughed and cried and caught up on each other’s lives. Now the empty place in my heart is filled.

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 ox-like 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 well-kept 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 well-preserved 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 animal 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 live in, but the other plants and animals they depended on for food may also be gone as well. It can be learned from the passage that ________.
| A．scientists have cloned the African bongo antelope |
| B．both the cheetah and the giant panda live in Asia |
| C．the gaur lives in Asia and is endangered |
| D．the gaur is an extinct species |
The underlined words “a surrogate mother” probably refer to a female who __________.
| A．contributes its eggs to another female |
| B．gives birth to a baby for another female |
| C．gives birth to a baby of its own |
| D．cannot give birth to a baby |
The difficulty in cloning an extinct species is the lack of ______.
| A．both the well-preserved DNA and plants to live on |
| B．both the habitat to live in and the well-preserved DNA |
| C．both habitat to live in and plants to live on |
| D．both the well-preserved DNA and a surrogate mother |
In the author’s opinion, it is possible that ______.
| A．some extinct species may be cloned, but not survive |
| B．extinct species may be cloned and easily survive |
| C．a gaur can have a monkey as a surrogate mother |
| D．all the extinct species may be cloned |
Which of the following statements is true according the passage?
| A．Jurassic Park is a cloned animal. |
| B．The cloned creatures are the same as the real one. |
| C．We could clone extinct animals in reality. |
| D．We could clone extinct animals in theory. |
