A newly-published study has shown that loneliness can spread from one person to another, like a disease. Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.

Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.     

University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.

Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.

The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.

The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.

Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.

The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.

1.What is TRUE about the Framingham Study?

A. It was only conducted in 1948.

B. It involves more than 12,000 participants.

C. It was led by John Cacioppo.

D. It showed that any behavior could spread.

2. Which statement about the spread of loneliness is true?

A. The spreading effect was the second strongest among friends.

B. No spreading effect was found on husbands and wives.

C. Women are more likely to be affected than men.

D. Brothers are more easily affected than neighbors.

3. What is the main idea of the passage?

A. Actions should be taken to help lonely people.

B. People feel lonely for many reasons.

C. Ways to fight against loneliness.

D. Lonely people can affect others.

Sometime early in the next century, human beings will move to Mars.They will live there for about a year, and then will be replaced with another group of pioneers.Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.

We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures.These resemblances have caused many people to consider a centuries-long project: to terraform Mars.Terraforming means altering a planet’s surface so that Earth’s life forms can survive there.This concept, previously found only in science fiction is now being seriously considered by scientists.

Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth.But it will take at least 300 years.

Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt.The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support.Our very existence and numbers are threatening many other species.We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate.Currently terraforming Earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.

Small as the possibility of such a project is, it is not impossible.Even if earth-bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.

The future existence of all the people in our world may very well depend upon our ability to terraform Mars.

What would be the best title for this passage?

      A.Terraforming Mars.       B.Saving the Earth.

      C.Travelling to Mars.       D.A Newly-found Place.

What does the underlined word “altering” mean in the second paragraph?

      A.Warming.         B.Changing.         C.Planting.          D.Building.

According to the passage the main purpose of terraforming Mars is to _____.

      A.do some scientific research work   

       B.find out its similarity to Earth

      C.avoid the dying away of many other species   

       D.find on Mars living place for the increasing human beings

The main reason for causing many people to consider terraforming Mars is that _____.

       A.there are some resemblances between Earth and Mars

       B.terraforming Mars is theoretically simple

       C.we have had some experience with terraforming our own planet: Earth    

       D.the development of science and technology is very rapid

   C
Thousands of people living in the Chinese eapital will celebrate the start of the Chinese New Year by heading for the ski resorts(滑雪場).Never mind that Beijing’s dry weather seldom produces
Now. It is cold enough in winter for snow-making machines to make a covering for the hills north to
The capital. And the rapid growth of a pleasure-seeking middle class has formed the basis for this
New craze(熱潮).
Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed an astonishing increase.There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr.Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts
In Europe.
Beijing’s sking craze is partly a result of the recent increase in private(私有的)cars. This has led to the growth of a leisure industry in the capital’s suburbs(郊區).which until the late-1990s were unreachable to ordinary people. According to Mr. Wei,About 40% of the visitors to his resort some in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money.Starting ski resorturequires quite a lot of money:hiring land from the local government,preparing the hills,buying snow machines,making sure there are enough
water and electricity to run them,and buying ski equipment for hiring out to customers.The ski resort where Mr.Wei works cost nearly $4m to set up.And,as so often in China when someone comes up with a good idea,many others rush in and price wars break out.Beijing now offers some of
the cheapest ski training classes in the world,though with most people rather new to the sport, expecting a few more doing the same job.
50.What does this text mainly talk about?
A.Convenience for skiers brought about by private cars
B.Skiing as a new way of enjoying one’s spare time
C.Things to be considered when starting a ski resort
D.A sudden increase of ski training classes in Beijing
51.Why are some Chinese likely to go skiing in Burope?
A.To visit more ski areas
B.To ski on natrual snow
C.For a large collection of ski suits
D.For better services and equipment
52.The underlined words”leisure industry”in Paragraph 3 refer to        
A.transport to ski resorts
B.production of familycars
C.business of providing spare time enjoyments
D.part-time work for people living in the suburbs
53.What is the main problem in running a ski resort?
A.Difficulty in hiring land
B.Lack of business experience
C.……ski resorts.
D.Shortage of water and electricity

GENEVA(Reuters) -Pregnant women and other people at high risk should be vaccinated(注射疫苗) against the H1N1 swine flu virus as the cold weather begins to bite in the northern hemisphere(半球), the World Health Organization(WHO) said on Tuesday.

It voiced concern that some vulnerable(弱勢的) people don’t have access to the pandemic(傳染病) vaccine, which the WHO stressed had not caused any unusual side effects in hundreds of thousands of people to have received it worldwide so far.

“Certainly the fact that the vaccine isn’t being used by those who would have access to it and who would be in priority risk groups is of concern, yes,” WHO spokesman Gregory Hartl told a news briefing.

At least 5, 712 people have died from the swine flu virus, according to the United Nations agency. Health workers, pregnant women and people with conditions such as asthma are deemed at greatest risk and should be top priority for getting the shot.

“We have seen many, many examples of people in high risk groups such as pregnant women who have very severe disease or outcomes. These outcomes could be in all likelihood avoided if one were to get vaccinated,” Hartl said.

Unlike seasonal flu, which is most dangerous to the elderly, H1N1 is hitting younger adults and children especially hard.

The WHO recommends a single vaccine dose for protecting adults against H1N1. It has also urged governments to consider giving a single dose to as many children under age 10 as possible, but says more research is needed into child dosages.

In the United States, studies show that children under the age of 9 will need two doses of the vaccine to be fully protected, officials there said on Monday.

Parts of North America and Europe have already crossed the epidemic (流行病) threshold( 開始了), ahead of the normal influenza season which peaks in January-February for the northern hemisphere, WHO says.

51.According to the passage, what is WHO probably most concerned about now?

A. Whether the vaccine has side effect or not.

B. How many people are infected by the H1N1 swine flu virus.

C. Whether pregnant women and those at high risk can get the vaccination.

D. What is the difference between H1N1 and seasonal flu.

52.According to the passage, what group of people are more vulnerable to H1N1 swine flu virus?

A. The elderly.                  B. A teenager with asthma. 

C. An adult with heatstroke.               D. A newly-born baby.

53.In paragraph 4, “getting the shot” means ____________.

A. being shot      B. being vaccinated     C. being cured     D. getting killed

54.What can we learn from this passage?

A. Pregnant women will surely get severe disease if infected with H1N1.

B. Seasonal flu is more likely to hit younger adults and children.

C. one more dose of vaccine should be given to the children under 9.

D. About 6000 people have died from seasonal flu.

55.   Which of the following statements is TRUE?

A. Pregnant women need flu shot. 

B. Differences between H1N1 flu and seasonal flu.

C. The harm caused by H1N1 swine flu virus.

D. A breakthrough in H1N1 cure: vaccination.
