In modern society, competition is everywhere. No wonder a English philosopher considers competition the source of a series of problem such as frustration and anxiety. Therefore, if we stress cooperation too much, there would be no progress. In my opinion, all are important and necessary.
Let's take the competition at school for example. Even a gifted student won't make a remarkable progress if he is in a class without competition. That's because competition, and rather, challenge is a driving force made him go forward. On the other hand, if we don't cooperate with each other, it's impossible for us learn from each other. And that's why most of the great discoveries or inventions in the modern world are the result of cooperation.
To conclude, those who laugh last are the people who can successful cope with the relationship between competition and cooperation.

The twentieth century saw greater changes than any century before. Changes for the better, changes for the worse, changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.

Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe. It has brought us a better understanding of the nature of life and of its continuous development. Technology in the application of science has made big advances that have benefited us in nearly every part of life.

The continuation of such activities in the twenty-first century will result in even greater advantages to human beings; in pure science—a wider and deeper knowledge in all fields of learning; in applied science--- a more reasonable sharing of material benefits, and better protection of the environment.

Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons. Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.

William Shakespeare said, “The web of our life is of a mingled yarn, good and ill together.” The above brief review the application of only one part of human activities—science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?

We don’t plan to cry, but it just happens. In fact when we feel sad or angry, a good cry is almost impossible to resist. But if you didn’t know what crying was, you’d have to wonder why some strong feelings started water streaming from people’s eyes and why they seemed to feel better afterwards.

Now a US researcher had found there may be more in crying than we think. William H. Frey II, author of “Crying: The Mystery of Tears,” believes it may really be one of the body’s clever self-repair mechanisms. Crying may be a way of getting rid of the by-products of stress, he says.

He has found that tears contain some chemicals which can cause stress. One of these is the hormone prolactin (激素), which is set free when one is feeling stressed. Since women have more of this than men, that might explain why they usually cry more, he suggests.

Unsurprisingly, Dr Frey’s study seemed to prove that most people feel better after a good cry. And sex has nothing to do with it ––– the result was true for women and men. So, next time you feel like bursting into tears, go ahead. If Dr Frey is right, you’ll be doing yourself a favour.

Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.

A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.

One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.

The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).

1.What’s the main idea of the first paragraph?

A．Explaining why there is a lack of rain at times.

B．Introducing several different patterns of rainfall.

C．Telling us how to avoid problems caused by rain.

D．Giving the idea that there are ways to manage rain water.

2.According to the second paragraph, “Rain Gardens" are likely to _____.

A．harm the environment in the short run

B．become popular over the next few years

C．be turned down by most new developments

D．be too expensive for common people to accept

3.We can learn from the third paragraph that _____.

A．floods are often the results of small rains

B．a heavy rain is less difficult for plants to absorb

C．the rain garden helps send rainwater back into the air

D．larger amounts of rainwater flow straight off in city environments

4.According to the last paragraph, what does the rain garden help to clean?

A．The plants B．The ground. C．The water. D．The street.
