Health is the most important thing in the world. Nothing is more important than health. If we take away our money, houses, cars or even our clothes, we can still survive.   71   That is why we always try to eat in a healthy way and exercise regularly.

How can we keep healthy？In order to eat healthily, I usually avoid eating food high in fat, like French fries or cookies, which are junk foods.   72   I eat a lot of vegetables and fresh fruit which are full of vitamins.

   73   Taking exercise every day helps us build a strong body. Regular exercise is an important part of keeping me healthy.

What’s more, I think friends are an important part of one’s health.   74   I always feel better when I am with friends than when I am alone. When I am with my friends, I always laugh. Laughing is also an important part of health. It is good to stay with my friends.

By eating properly and exercising regularly, I can keep my body at a proper weight and keep healthy. By spending time with my friends, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage them.    75  

A．On the other hand, doing exercise is very important．

B．There are some people who like staying alone, but they keep healthy．

C．Many studies show that people with a range of social contacts don’t get sick．

D．But if our health was taken away, it is certain that we would surely die．

E．I only eat little meat．

F．I think a strong will is necessary if we want to keep healthy．

G．Some people appear fat because they often eat too much．

We can make mistakes at any age．Some mistakes we make are about money．But most mistakes are about people．One might say, "Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad．
Why do we go wrong about our friends? Sometimes what people want to say hides their real meaning．And if we don't really listen, we miss the feeling behind the words． Suppose someone tells you, "You're a lucky dog．" Is he really on your side? If he says, "You are a lucky guy", that's being friendly．But if he says "a lucky dog", there's a bit of envy in those words．Maybe he doesn't see it himself．But he puts you down a little if he brings in the "dog"．What he may be saying is that he doesn't think you deserve your luck．
"Just think of all the things you have to be thankful for" is another noise that says one thing and means another．It could mean that the speaker is trying to get you to see your problem as part of your life as a whole．But is he trying to? Wrapped up in this phrase is the thought that your problem isn't important．It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night．
How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking．Do his words fit the way he looks? Does what he says agree with the tone of voice, his posture, or the look in his eyes? Stop and think．The minute you spend thinking about the real meaning of what people say to you may save another mistake．
Therefore, when you hear someone saying, please try to know what he really means．Don't just listen to what he says with your ears but feel the words he uses with your head．In this way you may make fewer mistakes．

．In the 1st paragraph, the writer says something that happened between him and his friends ____．

Unless we spend money to spot and prevent asteroids now，one might crash into Earth and destroy life as we know it，say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one，the scientists say，we'll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “If we don't take care of these big asteroids，they'll take care of us,” says one scientist. “It's that simple.”
The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.
【小题1】What does the passage say about asteroids and meteoroids?

A．They are heavenly bodies different in composition.

B．They are heavenly bodies similar in nature.

C．There are more asteroids than meteoroids.

D．Asteroids are more mysterious than meteoroids.

I want to talk about the economy．Not "the economy" we hear about endlessly in the news each day and in politicians' speeches．I want to talk about the real economy, the one we live in day by day．

Most people aren't particularly interested in "the economy"．"Share prices are flying high; interest rates are soaring;  the Dow Jones Index closed sixty-three points down on 8472．35．" We hear this and subconsciously switch off．

Notice that "the economy" is not the same as the economy, "The economy" is what men in suits play with to make vast personal wealth．The economy is where the rest of us live on a daily basis, earning our living, paying our taxes, and purchasing the necessities of life．

We are supposed to be benefiting from all the advantages of a well-off society．So why do we feel tired and stressed? We have no time for anything other than work, which is ridiculous given the number of labor-saving devices in our lives．Our towns become more and more crowded．We poison our air and seas, and our food is full of chemicals．There's something wrong here．If times were truly good, then you may think we'd all feel optimistic about the future．Yet the majority of us are deeply worried．More than 90 percent of us think we are too concerned about ourselves and not concerned enough about future generations．

The term "economic expansion" suggests something desirable, but expansion simply means spending more money．More spending doesn't mean that life is getting better．We all know it often means the opposite - greed, crime, poverty, pollution．More spending merely feeds our whole economic system, which is based on production and consumption．Unless money keeps circulating,  the economy breaks down．If we don't keep consuming,  the whole system goes into stalemate（僵局）．

How do we break the cycle and make some changes? We need to become far more aware of the results of our actions．We buy clothes that are made in sweat shops by virtual slaves in poor parts of the world．We create mountains of waste．We demand cheap food,  mindless of the fact that it totally lacks taste and is produced using chemicals that poison the land．

The consumption culture makes us unaware of the effect of our own behavior．Our main problem is not that we don't know what to do about it．It is gathering the desire to do it．
