It is over 40 years since first atomic bomb was dropped on a major city in Japan. Yet even now its effects are showing themselves and may continue to do so for years to come. Much effort and human energy have been used to try to prevent such a terrifying thing from happening again. So far there is no guarantee that it will not. Countries which already possess nuclear knowledge and resources have bombs stored away which are powerful enough to wipe out all life on earth. But this is not all. Other countries, which previously were not so advanced in technology, are gradually buying materials that can be used for making atomic devices. This nuclear energy will naturally be of great value in helping the economy of poorer nations.

The generation of electricity through nuclear power came directly from the original work on the atom bomb. Because of the increase in demand for energy and the possibility of decreasing supplies of oil and natural gas, the interest in electricity has increased. One of the by-products of nuclear power stations is plutonium (钸) produced from unclear fuel: plutonium is ingredient (成分) in bomb-making. It means that there are far more opportunities for the manufacture of bombs.

This brings the problem to a full circle again. How can something so valuable and useful be controlled so that it works for the benefit and not the destruction of man?

9. The effects of dropping the first atomic bomb ________.

A. are not over B. may go on forever

C. could last much longer D. will not be over in the near future

10. The writer says that enough atomic bombs have already been manufactured to ________.

A. wipe out Japan B. last forever

C. act as a peace-keeping device D. destroy all living things

11. The advantage of less developed countries being able to make atomic devices is that it ______.

A. gives them more opportunities for work B. will help poor countries to become richer

C. will enable them to make better explosives D. will be of great value to them

12. The second paragraph tells us that the increased demand for electricity today ________.

A. has led to the decrease in supplies of oil

B. means that more countries are interested in nuclear power

C. has increased the risk of accidental explosions

D. has increased the very means of producing more atomic bombs

Though “nanometer” is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.

Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?

Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation of the application of nano technology into medicine.

Ji(director Institute of Nanomedicine):

A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body.

Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away.

The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them more abrasion resistant,much easier to be cleaned,or oil repelling or moth proof.

Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not changed its property and function as a cup.It is not a magical medicine for curing and health care.

Which of the following shows the right relationship?

A.nanometer<millimeter<micrometer<meter

B.nanometer<micrometer<millimeter<meter

C.micrometer<millimeter<nanometer<meter

D.millimeter<micrometer<nanometer<meter

The underlined part in the last second paragraph but one is about_________.

A.the strong points of nano cups B.the shortcomings of nano cups

C.the uses of nano cups D.the wonders of nano cups

Which of the following does not show that nano cups are different from ordinary cups?

A.Nano cups can’t make people healthier.

B.Nano cups are made of a different material.

C.Nano cups are much easier to be cleaned.

D.Nano cups are hard to produce.

According to the text,nano cups in the market are_________.

A.only traditional products

B.ordinary cups covered with a little nanometer material on the surface

C.cups made of a nano material

D.cups made of a mixed material

He walked into the station café. He looked up at the clock there. It was only twenty to twelve. He found a seat and sat down, facing a large mirror on the wall. Just then, John, one of Tom’s friends, came in and sat with Tom.
“What time is your bus?” asked John.
“Oh, there is plenty of time yet,” answered Tom.
“Oh, I’ll get you some more tea then,” said John.
They talked while drinking. Then Tom looked at the clock again.
“Good heavens! It’s going back-ward!” he cried. “A few minutes ago it was twenty to twelve and now it’s half past eleven.”
“You are looking at the clock in the mirror,” said John.
Tom wanted to kick himself for being so foolish. The next bus was not to leave for another hour. He has never liked mirror since then.

阅读下列短文，从每题所给的四个选项(A、B、C、和D)中选出最佳选项。

Qian Xuesen is one of the pioneers of China's space science. As a world-famous expert on aerospace rockets and aerodynamics, he obtained great achievements in the areas of applied mechanics, engineering cybernetics and system engineering and made distinguished contributions to the foundation and development of Chinese aerospace undertaking(事业).

Graduated from Shanghai Jiaotong University in 1934, Qian Xuesen went to the United States to study in MIT, Massachusetts Institute of Technology, one year later. After receiving master's degree in MIT, he went to study in California Institute of Technology and received PhD degrees in both aerospace and mathematics.

In 1955, six years after the founding of People's Republic of China, Qian Xuesen returned to his motherland. His return brought China the hope of developing space science and its own missiles.

In 1956, Qian Xuesen put forward “Proposal on the Development of China's Aviation Industry for National Defense”. With the support from Zhou Enlai, the premier, and marshal Nie Rongzheng, Qian Xuesen began to prepare for the establishment of China's first missile and rocket research and development structure, the Fifth Research Institute of State Ministry of Defense. Henceforth（从此以后）, he has long been in charge of the chief technological research and development of China's missile, rocket and spacecraft.

Due to research and development led by Qian Xuesen, China successfully exploded its first atom bomb in 1964. Later, China launched its first man-made satellite, Dong Fang Hong I, to the earth orbit on April 24, 1970, becoming the fifth country in the world to independently launch satellite following the former Union of Soviet Socialist Republics, the USA, France and Japan. The satellite floated around the earth, blaring（高声播放） the song Dong Fang Hong, which has the same name as the satellite.

As a forerunner leading the development of China's aerospace science and technology, Qian Xuesen also provided chances for young scientists. Wang Yongzhi, former chief designer of China's manned-space project, has benefited a lot from Qian Xuesen. “He suggested that rocket of the second generation should be developed by our second generation scientists. This suggestion gave us chances to be general designers.” Recalling the experience working with Qian Xuesen, Sun Jiadong, general designer of China's lunar orbiter project, is very grateful. “He put great expectation on us and trusted us a lot. Whenever we made mistakes, he seldom blamed us, but helped us to find out the reason so we could avoid it in the future.”

Honored as Father of China's Missile and King of Rockets, Qian Xuesen never stopped his work on scientific research after he retired. He said he had no time to review the past, but looked forward to the future.

41. When did Qian xuesen begin to study in Massachusetts Institute of Technology?________

A. In 1955. B. In 1935. C. In 1936. D. In 1934.

42. Which of the following is about the five countries that launched man-made satellite independently before 1970?

A. The former Union of Soviet Socialist Republics, the UK, France, China and Japan.

B. The former Union of Soviet Socialist Republics, the USA, Japan, Canada and China.

C. America, France, Japan, China and Australia.

D. The former Union of Soviet Socialist Republics, America, France, Japan and China.

43. What does the underlined word “forerunner”(Paragraph 6) probably mean?

A. A leader. B. A pioneer. C. A competitor. D. A successful scientist.

44. According to the passage, which of the following about Qian Xuesen is NOT true?

A. In 1956, he made good preparations for the Fifth Research Institute of State Ministry of Defense.

B. He made outstanding contributions to the establishment and development of Chinese aerospace undertaking.

C. He returned to China, bringing China the hope of developing space science and its own missiles.

D. He devoted all his life to China’s space science.

45. It can be inferred from Paragraph 6 that ______.

A. Qian Xuesen is very concerned about the development of young scientists.

B. The help of Qian Xuesen is beneficial to young scientists.

C. Qian Xuesen gives many opportunities to general designers.

D. When the chief designers do something wrong, Qian Xuesen helps them find out the cause.
