Nowadays, science is developing at a high speed. With the development of science, many countries have improved their economy and raised their people’s living standards. Therefore, science is of great benefit to our daily life.
If we look at the things around us, we’ll find how closely our everyday life is related to science. In one case, at home we can turn on the central heating or air conditioner when we feel cold or hot, and we can watch TV or listen to the tape recorder for entertainment, and we can use a gas stove to cook our meals, and we have computers to help us with our work when we are working in the office, and we also have cars, buses, even planes as traffic tools when we go out. All these things are the results of the scientific development. It goes
without saying that without science our society cannot make rapid progress and our life cannot be comfortable and convenient.
Now that science is so significant in our daily life, we should try to make as many contributions as possible to the development of science. As college students, we must first of all study hard to gain useful scientific knowledge, and then put what we have learnt into practice. We should make the most of science to serve our society.
Our surrounding(周围) is being polluted faster than nature and man’s present efforts can’t prevent it. Time is bringing us more people, an more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are always ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from countryside to cities, eager for the benefit of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going—and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.

C．man can do little about the problem of pollution
D．the writer is worried about the future of our society
4.What does the writer really want to say in this passage?
A．With the development of technology, pollution has become a serious problem.
B．Lower the speed of development to stop pollution.
C．It’s time we did something to reduce pollution.
D．As industry is growing fast, pollution is the natural result.
Are you carrying too much on your back at school? You’re not alone. Back experts in the USA were worried that young students are having back and neck problems because they are carrying too much in their backpacks (schoolbags).
“It hurts my back when I run,” said Eglin Reyes, a student in Virginia. “It’s hard to get up the stairs with my backpack because it’s too heavy.”
Students have to carry heavy backpacks on their backs for a whole week’s study. Beeline is one of them. They have regular backpacks with two straps(带子) to carry them, but a number of students with heavy loads have switched to rolling backpacks. The backpacks have wheels and can roll on the ground.
Shirley Park’s backpack weighs 10 kilos, and she said, “I’ll change to a rolling backpack because I am starting to have back pain.”
How much is too much? Experts say that students should carry no more than 10 to 15 percent of their own body weight. A few students have had a good idea to lighten the load: Less homework.
Doctor’s suggestions:
●Lighten the load. Take home only the books the students need that night.
●Wide straps are better. They can send out weight over your shoulders and be sure to wear backpacks with two straps.
●The heaviest things should be packed closest to the back.
●Bend(弯曲) both knees when you pick up the pack, don’t just bend the waist(腰).

A. will know how to use backpacks
B. may feel their backpacks are lighter
C. can learn how to enjoy them

When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺点). Sometimes she said I was thin. Sometimes she said I was lazy. Sometimes she said I wasn’t a good student. Sometimes she said I talked too much, and so on. I tried to put up with(忍受) her as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, and then he asked, “Are the things she said true or not? Mary, didn’t you ever wonder what you’re really like? Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”
I did as he told me and to my surprise, I discovered that about half the things were true.
I brought the list back to my dad. He refused to take it. “That’s just for you,” he said. “You know better than anyone else the truth about yourself. When something said about you is true, you’ll find it will be helpful to you. Don’t shut your ears. Listen to them all, but hear the truth and do what you think is right.”
Many years have passed. The situation often appears in my mind. In our life we often meet with some trouble and we often go to someone and ask for advice. For some advice you will treasure(珍惜) all your life!

In the United States, 30 percent of the people have a “weight problem”. To many people, the cause is obvious: they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
1.Nowadays many Americans have the problem that ______.
A．they lose too much body fat B．they work too hard
C．they are too fat D．they are too slim
2.According to the passage, how many people in 900 Americans have a “weight problem”?
A．150. B．300. C．600. D． 270.
3.Is there any scientific evidence to support the idea that eating too much is the cause of a “weight problem”?
A．We are not sure.
B．Of course, there is some evidence to support this.
C．There is hardly any scientific evidence to support this.
D．Yes, there is plenty of evidence.
