The great majority of all earthquakes occur in two specific geographic areas. One such area covers the Pacific Ocean and its bordering landmasses. The other extends from the East Indians to the Atlas Mountains, including the Himalayas, Iran, Turkey, and the Alpine regions. It is in these two great belts or zones that ninety percent of all earthquakes take place; they may, however, happen anywhere at any time.
This element of the unknown has for centuries added greatly to the dread and horror surrounding earthquakes, but in recent times there have been indications that earthquake forecast may be possible. By analyzing changes in animal behavior, patterns of movements in the earth‟s shell, variations in the earth‟s force of attraction, and the frequency with which minor earth shakes are observed, scientists have shown increasing success in expecting when and where earthquakes will strike. As a result, a worldwide earthquake warning network is already in operation and has helped to prepare for (and thus lessen) the vast destruction that might otherwise have been totally unexpected.
It is doubtful that man will ever be able to control earthquakes and get rid of their destructiveness altogether, but as how and why earthquakes happen become better
understood, man will become more and more able to deal with their possible damage before they occur.
1.Which of the following statements is true according to the passage?
A. Earthquake destruction is declining
B. Earthquake forecast is improving
C. Man is no longer fearful of earthquakes.
D. Man is capable of conquering earthquakes
2.We can infer from the passage that quakes __________.
A. may happen anywhere at any time
B. mostly strike in oceans and mountains
C. are unobservable in masses of land
D. are hardly the direct cause of fatalities
3.The phrase “this element of the unknown” (Paragraph 3) refers to ___________.
A. the extension of earthquake zones
B. the percentage of earthquake occurrences
C. when and where earthquakes may occur
D. what big damage earthquakes may cause
4.Man‟s research on earthquake forecast at present is to ____________.
A. reduce the loss from earthquake disasters
B. lower the frequency of earthquakes
C. release the energy that causes earthquakes
D. analyze the relationship between different earthquakes
5. Which of the following describes the author‟s purpose in writing the passage?

More ambiguous than other scientific inventions familiar to modern artists, but no less influential, are the psychoanalytic studies of Freud and his followers, discoveries that have infiltrated recent art, especially Surrealism. The Surrealists, in their struggle to escape the monotony and frustrations of everyday life, claimed that dreams were the only hope. Turning to the irrational world of their unconscious, they banished all time barriers and moral judgements to combine disconnected dream experiences from the past, present and intervening psychological states. The Surrealists were concerned with overlapping emotions more than with overlapping forms. Their paintings often become segmented capsules of associative experiences. For them, obsessive and often unrelated images replaced the direct emotional message of expressionism. They did not need to smash paint and canvas; they went beyond this to smash the whole continuity of logical thought.
There is little doubt that contemporary art has taken much from contemporary life. In a period when science has made revolutionary strides, artists in their studios have not been unaware of scientists in their laboratories. But this has rarely been a one-way street. Painters and sculptors, though admittedly influenced by modern science, have also molded and changed our world. If break-up has been a vital part of their expression, it has not always been a symbol of destruction. Quite the contrary: it has been used to examine more fully, to penetrate more deeply, to analyze more thoroughly, to enlarge, isolate and make more familiar certain aspects of life that earlier we were apt to neglect. In addition, it sometimes provides rich multiple experiences so organized as not merely to reflect our world, but in fact to interpret it.
According to the 'passage, it is true that ______.
A.artistic creations seem to be the reproductions of modern technology
B.artistic creations have made great strides scientifically
C.artistic creations appear to be incapable of ignoring material advances
D.artistic creations are the reflection of the material world
In my fridgeless Fifties childhood, 1 was fed well and healthy.The milkman came every day, the grocer, the butcher (肉商), the baker, and the ice-cream man delivered two or three times each week.The Sunday meat would last until Wednesday and surplus(剩余的) bread and milk became all kinds of cakes.Nothing was wasted, and we were never troubled by rotten food.Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.
The invention of the fridge contributed comparatively little to the art of food preservation.Many well-tried techniques already existed -- natural cooling, drying, smoking, salting, sugaring, bottling...
What refrigeration did promote was marketing --- marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.
Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary.Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house -- while outside, nature provides the desired temperature free of charge.
The fridge's effect upon the environment has been evident, while its contribution to human happiness has been not important.
1.The statement "In my fridgeless fifties childhood, I was fed well and healthily." suggests that the author was well-fed and healthy even without a fridge in his fifties.()
2.The author says that nothing was wasted before the invention of fridges because people had effective ways to preserve food.()
3.Consumers benefited the most from fridges according to the author?()
4.What refrigeration did promote was food-preserving.()
5.The author is critical to fridges.()
