Mark your answers on ANSWER SHEET 1. 50 The concept of obtaining fresh water from icebergs that are towed to populated regions of the wo
18、rld was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source
19、of fresh water that have been overlooked until recently. Three quarters of the Earths fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1, 000 years. Floating on the oceans every year are 7, 659 tr
20、illion metric tons of ice encased in 10, 000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed wh
21、en the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface currents. Because they melt more slowly than s
22、maller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic ocean. To corral them and steer them to parts of the world where they are needed would not be too difficult. The difficulty arises in other technical matters, such as the preventio
23、n of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water. 51 The main idea of the pa
24、ssage is about_. （ A） the movement of glaciers （ B） icebergs as a source of fresh water （ C） future water shortages （ D） the future of the worlds rivers 52 The word “it“ in line 2 refers to_. （ A） an iceberg that is towed （ B） obtaining fresh water from icebergs （ C） the population of arid areas （ D
25、） real life 53 According to the author, most of the worlds fresh water is to be found in_. （ A） oceans （ B） rivers （ C） glaciers （ D） reservoirs 54 How are icebergs formed? （ A） They break off from glaciers. （ B） Seawater freezes. （ C） Rivers freeze. （ D） Small pieces of floating ice converge. 55 Th
26、e word “desalination“ in the last sentence may mean_. （ A） river freezing （ B） iceberg forming （ C） removing salt from water （ D） iceberg floating 55 Every year television stations receive hundreds of complaints about the loudness of advertisements. However, federal rules forbid the practice of maki
27、ng ads louder than the programming. In addition, television stations always operate at the highest sound level allowed for reasons of efficiency. According to one NBC executive, no difference exists in the peak sound level of ads and programming. Given this information, why do commercials sound so l
28、oud? The sensation of sound involves a variety of factors in addition to its peak level. Advertisers are skilful at creating the impression of loudness through their expert use of such factors. One major contributor to the perceived loudness is that much less variation in sound level occurs during a
29、 commercial. In regular programming the intensity of sound varies over a large range. However, sound levels in commercials tend to stay at or near peak levels. Other “tricks of the trade“ are also used. Because low-frequency sounds can mask higher frequency sounds, advertisers filter out any noises
30、that may drown out the primary message. In addition, the human voice has more auditory impact in the middle frequency ranges. Advertisers electronically vary voice sounds so that they stay within such a frequency band. Another approach is to write the script so that lots of consonants are used, beca
31、use people are more ware of consonants than vowel sounds. Finally, advertisers try to begin commercials with sounds that are highly different from those of the programming within which the commercial is buried. Because people become adapted to the type of sounds coming from programming, a dramatic c
32、hange in sound quality draws viewer attention. For example, notice how many commercials begin with a cheerful song of some type. The attention-getting property of commercials can be seen by observing one-to-two-year-old children who happen to be playing around a television set. They may totally igno
33、re the programming. However, when a commercial comes on, their attention is immediately drawn to it because of its dramatic sound quality. 56 According to the passage, the maximum intensity of sound coming from commercials （ A） does not exceed that of programs （ B） is greater than that of programs （
34、 C） varies over a large range than that of programs （ D） is less than that of programs 57 Commercials create the sensation of loudness because_. （ A） TV stations always operate at the highest sound levels （ B） their sound levels are kept around peak levels （ C） their sound levels are kept in the mid
35、dle frequency ranges （ D） unlike regular programs their intensity of sound varies over a wide range 58 Many commercials begin with a cheerful song of some kind because_. （ A） pop songs attract viewer attention （ B） it can increase their loudness （ C） advertisers want to make them sound different fro
36、m regular programs （ D） advertisers want to merge music with commercials 59 One of the reasons why commercials are able to attract viewer attention is that （ A） the human voices in commercials have more auditory impact （ B） people like cheerful songs that change dramatically in sound quality （ C） hi
37、gh-frequency sounds are used to mask sounds that drown out the primary message （ D） they possess sound qualities that make the viewer feel that something unusual is happening 60 In the passage, the author is trying to tell us_. （ A） how TV ads vary vocal sounds to attract attention （ B） how the loud
38、ness of TV ads is overcome （ C） how advertisers control the sound properties of TV ads （ D） how the attention-getting properties of sounds are made use of in TV ads 60 A very important world problem in fact, I think it may be most important of all the great world problems which face us at the presen
39、t time is the rapidly increasing pressure of population on the land. The population of the world today is about 4, 000, 000, 000. That is an enormous number, yet it is known quite accurately, because there are very few parts of the world which have not carried out a modern census. The important thin
40、g is not so much the actual population of twenty million about six months increase in world population. Take Australia. There are ten million people in Australia. So it takes the world about three months to add to itself a population which peoples that vast country. Let us take our own crowded count
41、ry, England and Walesforty-five to fifty million people. This is just about a years supply. By this time tomorrow, and every day, there will be added to the earth about 120. 000 extra people just about the population of the city of York. I am not talking about birth rate. This is net increase. To gi
42、ve you some idea of birth rate, look at the second hand of your watch. Every second, three babies are born somewhere in the world. Another baby! Another baby! You cannot speak quickly enough to keep up with the birth rate. This enormous increase of population will create immense problems. Unless som
43、ething terrible happens, there will be as many as 7, 000, 000, 000 people on the surface of the earth! So this is a problem which you are going to see in your lifetime. 61 The population of the world today is about_. （ A） 400 million （ B） 4 billion （ C） 400 million （ D） 40 billion 62 England and Wal
44、es_. （ A） have a bigger population problem than Australia （ B） have the same population increase rate as Australia （ C） have the same number of people as the worlds yearly increase （ D） can supply Australia with a whole years increase of people 63 According to the author, Australia_. （ A） has a popu
45、lation of twenty million （ B） is a vast country that needs a bigger population （ C） constitutes one-fourth of the worlds population increase every year （ D） has a population that happens to be one-fourth of the yearly world increase 64 The present net increase of world population is_. （ A） 180 per m
46、inute （ B） one per second （ C） 120, 000 per week （ D） too many to be counted 65 In the last paragraph, what does the author probably imply by “something terrible“? （ A） Population explosion. （ B） Land shortage. （ C） Exhaustion of life supply. （ D） Natural disasters or wars. Part B Directions: In the
47、 following article some paragraphs have been removed. For Questions 66-70, choose the most suitable paragraph from the list A-F to fit into each of the numbered gaps. There is one paragraph which does not fit in any of the gaps. Mark your answers on ANSWER SHEET 1. 65 For the first time, scientists
48、have profiled specific genetic changes during the aging of experimental animals, a discovery that could aid work to extend life span and preserve health. The study, conducted with mice at the University of Wisconsin, combines a powerful new genetic technique with dietary restriction, the only known
49、way to delay the aging process. 66. Moreover, it reveals how a low-calorie diet, the only known method of slowing aging in several animal species, works at the most basic level to extend life span and preserve health. Such knowledge, used in concert with new technologies capable of rapidly surveying the activity of thousands of genes at once, premises to accelerate the development of drugs that mimic the age-retarding eff
