Several regions in the world are subject 21_______ storms which are so severe that they cause damage on a tremendous scale. The regions are all located on the edges of great oceans. The 22_______ term for such severe storms is “cyclone”(龙卷风). The term “hurricane” is 23_______ for storms that occur in the North Atlantic Ocean.Cyclones and hurricanes differ in one curious 24_______ : in a cyclone, the wind circulates in a clockwise direction; in a hurricane, the wind direction is counter-clockwise. 25_______ cyclones and hurricanes have one ominous similarity. 26_______ the damage they cause on land and at sea， they are identical.Australia undergoes a number of cyclones every year along its northern coast, which faces Indonesia. The cyclones occur mainly in December and January, the summer months in the southern hemisphere.27_______ the Australian cyclones don’t cause great damage because Australia’s northern territory has vast empty regions that are virtually unpopulated. There are 28_______ coastal cities. When a cyclone does move inland from the sea, it usually blows itself out without 29_______ any inhabitated area. However, in 1917 the small city of Townville was 30_______ devastated by a cyclone. There was a public outcry about it. People demand an adequate warning system.

Passage 1Music which is original is individual and personal. That is to say, it can be identified as belonging to a particular composer. It has particular qualities, or a style, which are not copied from another. If you can recognize the style of a composer, you will probably be able to tell that a certain composition belongs to him or her even though you have never heard it before. A basket—maker has the skill of weaving and interweaving his materials to create colorful patterns, and an expert carpenter (木匠) has the skill of joining together different shapes and sizes of wood to make a beautiful piece of furniture. These skills may be referred to as “workmanship” (技艺). Similarly, in music a composer organizes his melodies (旋律) and rhythms and combines sounds to create harmony. A composer may be capable of thinking up very good, original tunes, yet if tunes are poorly organized, that is, if the workmanship is poor, the final result will not be to standard.Good music expresses feelings in a way that is suitable to those feelings. There may be joy, sorrow, fear, love, anger, or whatever. Bad music, on the other hand, may confuse unrelated feelings, it may not express any important feeling at all, or it may exaggerate some feelings and make them vulgar, that is, cheap and ugly. Good music will stand the test of time. It will not go out of fashion but will continue to be enjoyed and respected long after it is first introduced. It will gain a kind of permanent status while bad music will disappear and be forgotten quickly. In pop music, where the general rule seems to be “the newer the better”, the test of time is the hardest test of all to pass.31.A piece of original music _______.

Passage 2If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question.It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4,000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write.Sometimes, of course, even if the people cannot write, they may know something of the past. For most people are proud to tell what their fathers did in the past. This we may call “remembered history”. Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written records, such spoken stories are often very helpful.34.Which of the following ideas is not conveyed in the passage?

Passage 3The advent of computers has brought with it a new set of opportunities for mischief (危害) and crime. Today, computers are easy to come by and many people know how computer technology works. More importantly, the growing use of computer networks can multiply a breach (破坏) of security, making larger numbers of people more vulnerable(脆弱的) than would be the case if they were using single, stand-alone computers.What’s more, computer experts agree that despite recent widespread publicity-computer viruses(病毒) are only one of many computer security problems facing the nation.The U.S. Defense Advanced Research Project Agency has requested that the Research Council’s(委员会) Computer Science and Technology Board assess(评定) the security problems posed by computer technology, see what solutions may already exist, review research efforts aimed at avoiding security problem in the future, and evaluate existing policies relevant to computer security. The study committee will examine the issue of security for a broad spectrum of users, including the business, national security, and academic communities, as well as the general public.David D.Clark, senior research scientist, Laboratory for Computer Science, Massachusetts Institute of Technology, will chair the committee of experts in electronic security, net work security, computer law, software engineering, cryptography(密码编制), and operating systems. The committee will also include computer users from the defense and banking industries.37.Which of the following is most likely to be agreed by computer experts?
