As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.

Wash Your Hands

And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.

Get Enough Sleep

This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.

Keep Hydrated

Drink enough water each day to clear poisonous matter from your system and keep up good moisture（湿度）production in your body.

Eat Immune-Improving Foods

Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陈代谢）, make you feel inactive, and weaken your immune system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.

Avoid Alcohol

Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.                         

Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!

Avoid Contact with Sick People

If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.

Know When to Get Help

A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.

44．To fight A/H1N1 infection, it’s helpful for us to_______ .

       A．sing “Happy Birthday” while washing hands

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

When the star begins to die ______.

A. there is no fuel left in it                                B. its outer layer goes into space first

C. a huge explosion will happen                         D. it doesn’t give off light any longer

A. The gravity inside the star is very strong.        B. The light can’t go out of the star.

C. The star becomes smaller and smaller             D. The dying star shines very brightly.

The black hole ______.

A. continues becoming smaller and smaller all the time

B. goes into another universe and becomes a white hole

C. can pull in everything we know of in the world

D. will appear at another place at a different time

B. How Do Black Holes Come Into Being?

C. What Are Black Holes?

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.                              

Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.                                                

The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.                                                               

People are finding less and less time for relaxing themselves because_____.                                                  

A. they do not know how to enjoy themselves                                       

B. they do not believe that relaxation is important for health      C. they are travelling fast all the time                                                    

D. they are becoming busier with their work  

According to the writer, the most important character for a good manager is his ________.   

A. not fearing stress                                                  B. knowing the art of relaxation         

C. high sense of responsibility                                   D. having control over performance   

Which of the following statements is true?  

A. We can find some ways to avoid stress. 

B. Stress is always harmful to people. 

C. It is easy to change the habit of keeping oneself busy with work.  

D. Different people can withstand different amounts of stress.  

In Paragraph 3, "such a reaction" refers back to_______. 

A. "making a choice between 'flight' or 'fight'"                                                         

B. "reaction to stress both chemically and physically"                                                      

C. "responding to crises quickly"

D. "losing heart at the signs difficulties" 

In the last sentence of the passage, "do so " refers to ______.     

A. "expose ourselves to stress"                               

B. "find ways to deal with stress" 

C. "remove stress from our lives"                   

D. "established links between diseases and stress"

A couple of years ago,before a trip to China,Nicole Davis and her US women’s volleyball teammates were warned about the prominence (显著、突出) of coach “Jenny” Lang Ping in her native country.

“I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,”said Davis.

Known as the “Iron Hammer” for her punishing spikes(扣球),Lang made it possible for China to dominate in the sport in the early 1980s.She was a key player on China’s 1984 Olympic gold medal winning team.

When the US team arrived for the Olympics,Lang,48,who is from Beijing,had to take a different route to avoid a crowd of reporters and fans.

Then came the greatest moment to Lang：While the US team was playing in a packed gym,at least 8,000 Chinese fans unfurled an American flag.

“That really says it all,” Davis said.“They look at her as an icon(偶像)．I’m sure it’s hard for them to see her coaching another country,but they love her so dearly that her success is their success.”

The loyalty of the Chinese fans was tested on Friday,when China lost a match to the US.

“It’s a pity that China lost the match,but I’m still glad that Lang Ping’s team won,since she is the pride of China’s volleyball,” said Liu Chengli,a spectator.“We also cheered for

Lang’s victory.”

Lang said she just tried to stay professional when the two teams meet.“It doesn’t matter if we play China or any other team.It’s the same.” Lang said.

Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players,said US volleyball player Lindsey Berg.

“It’s such an honor to be here and play for our coach here in China,”she said.“The amount of support that the Chinese give to her and us has been tremendous.The whole event has been unbelievable.”
