The first use of atomic weapons was in 1945, and their power ____increased enormously ever since.

A. is B. was C. has been D. had been.

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

On the night of May, 7,1942, a plane took off from an Air Force base in England to stop German fighters over the English Channel. The pilot of the plane was Captain Thomas Nash. Looking eastward, Nash saw twelve orange lights in a row, moving at an extremely high speed. As an experienced flyer, he had never seen anything like them. Thinking that they might be a new German weapon, he decided to follow them. But when he swung the plane around and headed directly for the lights, they disappeared.
Captain Nash may have been the first to see such orange lights but he wasn’t the last. His experience was repeated several times by pilots during World War Ⅱ in Europe and the Far East. What were they? No one knows for sure, but there is an interesting theory to explain them. According to this theory, the orange lights are space animals – animals specially adapted to life in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea. These space animals, the theory says, live so far up in the atmosphere that they are invisible from the earth. They feed in part on the air and partly on energy from sunlight. Being almost pure energy themselves, they can give light at night. During the day they become invisible.
Before World WarⅡ, continues the theory, there was little radiated (辐射) energy available on the earth’s surface. Then came the development of rockets, atomic reactor (核反应堆), and hydroelectric (水力发电的) plants. The space creatures are attracted by these sources of energy. At night when no energy is sent from sunlight, they go down into the lower levels to search a meal. They may even come into the scope of human eyesight. This explains the fact that they have been sighted now and then from the earth since 1942.
54．Which of the following best states the main idea of the passage?
A．The secret of nature can be completely explained.
B．Captain Nash may have been the first to see the lights in space.
C．Captain Nash saw twelve orange lights moving at a high speed.
D．According to an interesting theory, the orange lights are space animals.
55．The strange orange lights were first seen         .
A．from the ground                                  B．from a rocket ship
C．during World War I                             D．during World WarⅡ
56．The theory says that during the daytime the space animals        .
A．can’t be seen                                       B．shine brightly in the sky
C．can be seen from the earth                    D．visit the earth’s surface
57．If the space theory is true, the creatures go down to the lower places in order to         .
A．make connection with man                   B．search for man – made energy
C．attract curiosity                                   D．escape detection
