The flu season arrives so predictably, and affects so many of us, that it’s hard to believe that scientists have had very little idea why cold weather helps germs to spread.

Worldwide, up to five million people catch the illness each flu season, and around a quarter of a million die from it. Part of its power comes from the fact that the virus changes so quickly that the body is hardly prepared. “The antibodies we’ve built up no longer recognize the virus – so we lose our immunity,” says Jane Metz at the University of Bristol. It also makes it harder to develop effective vaccines, and even if one comes out, governments often fail to persuade enough people to take it up.

The hope is that by understanding better why flu spreads in winter, but naturally fades in summer, doctors could find simple measures to stop its spread.

Previous theories had centred on our behaviour. We spend more time indoors in the winter, meaning that we’re in closer contact with other people who may be carrying germs.

Another popular idea concerned our physiology(生理机制): the cold weather weakens your body’s defenses against infection. In winter, without much sunlight, we may run low on Vitamin D, which helps power the body’s immune system. Moreover, when we breathe in cold air, the blood vessels in our nose shrink, which affects the normal function of white blood cells, allowing viruses to slip past our defenses unnoticed.

While such factors both play some role, analyses suggested another ignored cause may have been lying invisible in the air that we breathe. Thanks to the laws of thermodynamics(空气热力学), cold air can carry less water vapor before it reaches the “dew point” and falls as rain. So while the weather outside may seem wetter, the air itself is drier as it loses the moisture. And researches in the past few years has shown that these dry conditions seem to offer the perfect environment for the flu virus to flourish.

In wetter air, the epidemic struggles to build strength, while in drier conditions it spreads like wildfire. And comparing 30 years’ climate records with health records, Jeffrey Shaman at Columbia University found that flu epidemics almost always followed a drop in air humidity.

1.What can we infer from the second paragraph ?

A.We lose immunity due to the absence of our antibodies.

B.The antibodies fail to function due to variation of virus.

C.Government should come up with better ways to persuade people.

D.One in four of the infected die from the influenza each flu season.

2.What is the purpose of understanding better why flu spreads in winter?

A.To help develop effective vaccine.

B.To seek ways to treat people infected with flu.

C.To figure out ways to cut off its transmission.

D.To explore how to defend our immune system.

3.In what weather condition a flu epidemic is more likely to occur ?

A.Destroying bodies’ immune system.

B.Powering our bodies’ immune system.

C.Killing numerous viruses that we take in.

D.Stopping us acquiring enough Vitamin D.

4.What is the best title of the passage?

A.Ways to prevent infection of flu B.Flu-A disease not so hard to prevent

C.A predictable flu season D.Why germs spread in winter

Thousands of people in the world are a hundred years old － or more and certain parts of the world are famous for the long lives of their inhabitants: the Vilacamba Valley in Ecuador, and the home of the Hunzas in the Himalayas.

Why do so many people live to a healthy old age in certain parts of the world? What is the secret of their long lives? Three things seem to be very important: fresh air, fresh food and a simple way of life. People work near their homes in the clean mountain air instead of traveling long distances to work by bus, car or train. They do not sit all day in busy offices or factories, but work hard outdoors in the fields. They take more exercise and eat less food than people in the cities of the West. For years the Hunzas of the Himalayas did not need policemen, lawyers or doctors. There was no crime, no divorce and not much illness in their society. They were a happy, peaceful people, famous all over India for their long, healthy lives.

Do you want to live to a hundred years old? Here are some rules for success. First, live in the right place. Second, choose the right kind of job. Doctors, dentists and bus－drivers die young. Farmers, priests and orchestral conductors live much longer. If you are in the wrong kind of job, you can still improve your way of life.

An old man in the Caucasus was talking about his past life. “I was young then，” he said, as he described his 87th year. His secret was: “Think young and stay young.” An old woman from Missouri, the USA, gave this advice, “Drink a little whisky and some warm beer every day.” An English lady just said, “Take a cold bath every morning.” The shortest, simplest piece of advice came from Mr Jim Chapman, aged 103. “Just keep breathing，” he told reporters.

1.Who is most likely to live a long life?

2.We can see from the passage that long－lived people avoid ______.

3. The passage indicates that we can change our ______ to live a long life.

4.What is mainly talked about in the last paragraph?
