The demands of the modern world are growing day by day and this is putting more pressure on scientists to do research. However, as stated by Griffiths, “There is no hope of doing perfect research”. Naturally, there have been a lot of criticisms (批评), as many scientists immediately announce that their research methods are very safe and that they have the perfect research theory (理论).

However, scientific history is filled with examples, in which a perfect scientific solution that was based on decades of scientific research has been overturned (推翻) with new theories. Naturally the first example that comes to mind is the fact that Newton’s Theories were thought to be very safe and they were used in all fields of science. For centuries, thousands of scientists around the world used Newton’s Theories to formulate (规划) other theories.

However, after nearly two centuries of use, Newton’s Theories were found to be not as perfect as they were thought. Through Einstein’s publication on the General Theory of Relativity, it was found that Newton’s laws were imperfect in explaining all motions (运动) that were taking place in our universe. It was found to be imperfect under some conditions, even though, Newton’s laws are still used today to predict motion at low speeds.

Thus, perfect research is only a myth (神话). Of course, this does not mean that a scientist should simply give up and accept imperfection in his or her research efforts. Improvements and changes in research techniques and methods are a natural part of evolution (进化) and it is each scientist’s responsibility to take it forward as much as possible.

While the final answer to the universe’s questions may never exist, a time will come when there will be fewer questions as new answers are found and more improved research is carried out by scientists around the world.

1.Why have there been a lot of criticisms?

A. The modern world demands mor e and more.

B. Scientists have a negative attitude.

C. Many scientists arrive at their conclusions (结论) too fast.

D. Griffiths does not believe what scientists say.

2.Through the publication of the General Theory of Relativity, Newton’s Theories turned out to be ______.

A. not so perfect　　 B. completely wrong　　 C. very safe　　 D. very exact

3.What will scientists do to deal with the “imperfectness” problem?

A. Accept the fact and give up.

B. Improve and change their methods and techniques.

C. Try their best to carry out the perfect study.

D. Ignore it and do as they please.

4.We can learn from the last paragraph that ______.

A. the universe’s questions are sure to have a final answer

B. the number of questions is sure to increase with the passing of time

C. scientists are carrying out improved studies

D. there will be more scientists in the world in the future

The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.

Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.

Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.

The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.

1. _______, our world is becoming much smaller.

A. Because of the rise in pollution

B. Thanks to science development

C. Because the earth is being polluted day and night

D. Because the earth is blown away by the wind every year
