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

A metaphor is a poetic device that deals with comparison. It compares similar qualities of two dissimilar objects. With a simple metaphor, one object becomes the other: Love is a rose. Although this does not sound like a particularly rich image, a metaphor can communicate so much about a particular image that poets use them more than any other type of figurative language(修辞). The reason for this is that poets compose their poetry to express what they are experiencing emotionally at that moment. Consequently, what the poet imagines love to be may or may not be love we see it. Therefore, the poet’s job is to enable us to experience it, to feel it the same way as the poet does.
Let’s analyze this remarkably unsophisticated metaphor concerning love and the rose to see what it offers. Because the poet uses a comparison with a rose, first we must examine the characteristics of that flower. A rose is spectacular in its beauty; its petals(花瓣) are nicely soft, and its smell is pleasing. It’s possible to say that a rose is actually a feast to the senses of sight, touch, and smell. The rose’s appearance seems to border on(近似于)perfection, each petal seemingly symmetrical(对称的) in form. Isn’t this the way one’s love should be? A loved one should be a delight to one’s senses and seem perfect. However, there is another dimension added to the comparison by using a rose. Roses have thorns(刺). The poet wants to convey the idea that roses can be tricky(机警的). So can love, the metaphor tells us. When one reaches out with absolute trust to touch the object of his or her affection, ouch, a thorn can cause great harm! “Be careful,” the metaphor warns: Love is a feast to the senses, but it can overwhelm us, and it can also hurt us and cause acute suffering. This is the poet’s perception of love--a warning. What is the point? Just this: It took almost 14 sentences to clarify what a simple metaphor communicates in only four words! That is the artistry and the joy of the simple metaphor.
According to the passage, what is a metaphor?
A. A comparison between two different objects with similar features.
