21、第一篇 Hydrologic Cycle Water on the earth is being continuously recycled in a process known as the hydrologic cycle. The first step of the cycle is the evaporation of water in the oceans. Evaporation is the process of water turning into vapor, which then form s clouds in the sky. The s***nd step is the water returning to the earth in the form precipitation, either rain, snow, or ice. When the water reaches the earth#39; s surface, it runs off into the river, lakes and oceans, where the cycle begins again. Not all water, however, stays on the surface of the earth in the hydrologic cycle. Some of it seeps into the ground through infiltration and collects under the earth#39;s surface as groundwater. This groundwater is extremely important to l ife on earth since 95% of the earth#39;s water is in the oceans, and is too salty f or humans or plants. Of the 5 % on land, only 0.05% is above ground in rivers or lakes. The rest is underground water. This groundwater is plentiful and dependa ble, as it doesn#39;t depend on seasonal rain or snow. It is the major source of wa ter for many cities. But as the population increases and the need for water also increases, the groundwater in some areas is getting dangerously low. Added to t his problem is an increasing amount of pollution that seeps into the groundwater . In the future, with an increasing population and more toxic waste, the hydrol ogic cycle we depend on could b***me dangerously unbalanced.Clouds are formed from
A.water vapor.
B.evaporation.
C.the hydrologic cycle.
D.groundwater.
22、(见21题)Water returns to the earth by
A.infiltration.

B.comes from toxic waste.
C.is 0.05% of all water.
D.ollects under the earth.
24、(见21题)The amount of groundwater is
A.about 95% of all water.
B.less than 5% of all water.
C.0.05% of above groundwater.
D.95% of above groundwater.
25、(见21题)The supply of groundwater is getting low because
A.conservation.
B.toxic waste.
C.pollution.

26、第二篇 How Does a Refrigerator Work? Before a liquid changes into a gas, it must be heated. We see this happening when a kettle boils on a fire. Before a gas can change into a liquid, it must l ose heat. This is the principle on which a refrigerator works. All refrigerators must, therefore, contain a liquid refrigerant, which can t urn easily into a gas and back again into a liquid. A refrigerator stores food, and so it is much better if the liquid is clean and safe and has no strong smell . For this reason, most refrigerants are chemicals which contain the gas fluorin e. They have all the necessary qualities. At the bottom of a refrigerator there is an electric pump. This pump forces the liquid through a pipe to the top of the refrigerator. Here the pipe branches out into many channels and b***mes a gas. But in order to change into gas, it m ust be heated; and so it takes heat from the freezer. So the freezer b***mes the coldest part of the refrigerator, where water turns into ice and food is frozen . Any warm air in the refrigerator rises towards the freezer and helps to chan ge the liquid refrigerant into gas. The gas flows round to the bottom again, whe re the pump compresses it. When this gas is compressed, it loses heat; and turni ng back into a liquid. The heat escapes from the refrigerator into the air outsi de. The liquid refrigerant now starts its journey again and soon reaches the fre ezer. There, it draws in more heat and again b***mes a gas. And so the process g oes on and on.Why is refrigerator cold inside?
A.Because it gives its heat to the refrigerant.
B.Because this is the principle on which a refrigerator works.
C.Because the fluorine gas is always very cold.
D.Because the refrigerator stops the air outside from coming inside.
27、(见26题)How can a gas be given a liquid form?
A.By burning it.
B.By heating it.
C.By pumping it through a pipe.
D.By compressing it.
28、(见26题)What is the most necessary quality of a good refrigerant?
A.It must be safe chemical to use in the house.
B.It must be clean.
C.It must readily turn from gas to liquid and from liquid to gas.
D.It must not have a strong smell.
29、(见26题)How does the refrigerant b***mes a gas?
A.It does this very easily by itself.
B.It draws heat from the freezer ant its contents.
C.It draws heat from the warm air outside the refrigerator.
D.It draws the heat escaping from the refrigerator.
30、(见26题)What is the use of electric pump in the refrigerator?
A.To let the heat in the refrigerator escape into the air.
B.To force the liquid refrigerant to the top of the refrigerator.
C.To compress the gas into a liquid.
D.Both B and C
31、第三篇 Energy Crisis The energy crisis has been with us for a long time and will be with us for a n even longer time. Whether Arab oil flows freely or not, it is clear to everyon e that world industry cannot be allowed to depend on so breakable a base. The su pply of oil can be shut off unexpectedly at any time, and in any case, the oil w ells will all run dry in thirty years or so at the present rate of use. New sources of energy must be found, but it is not likely to result in any situation which will ever restore that sense of cheap and plentiful energy we h ave had in the times past. To make the situation worse, there is as yet no sign that any slowing of t he world#39;s population is in sight. Although the birthrate has dropped in some na tions, including the United States, the population of the world seems sure to pa ss six billion as the twenty?first century opens. Taking all this into account, what might we reasonably estimate supermar kets to be like in the year 2001 ? To begin with, the world food supply is going to b***me steadily tighter o ver the next thirty years?even here in the United States. By 2001, the populati o n of the United States wilt be at least two hundred fifty million, and the nati on will find it difficult to expand food production to fill the additional mouth s. This will be particularly true since energy shortage will make it difficult t o continue agriculture in the high?energy American fashion that makes it possib le to combine few farmers with high yields. It seems almost certain that by 2001 the United States will no longer be a g reat exporting nation and that, if necessity forces exports, it will be at the p rice of belt?tightening at home. In fact, as food items will tend to decline in quality and decrease in varie ty, people will have to accept more !unnatural food".The passage is mainly concerned with.
A.the pressing general problems in the near future
B.energy crisis and new sources of energy
C.population and food supply in the United States
D.crisis in producing and marketing food
32、(见31题)According to the passage, which of the following statements about energy crisis is true?
A.World industry can count on Arab oil for at least half a century.
B.Energy supply will be exhausted when the oil wells run dry.
C.New sources of energy will be found and there no need for worrying.
D.The failure is not happy if the current situation keeps going on.
33、(见31题)When referring to the world#39;s population, the writer implies that .
A.in some nations the birthrate keeps increasing
B.in the United States the birthrate keeps decreasing
C.the United States is a typical example of population xplosion
D.in spite of the increased population food supply will be adequate
34、(见31题)Why does the writer mention !supermarkets" in his argument?
A.To demonstrate the tightening relation between food supply and population increase.
B.To show the important role the supermarkets play in the United States.
C.To predict that in the next thirty years the US will surely be short of food.
D.To estimate how the supermarkets should be run in the twenty?first century.
35、(见31题)It can be inferred that by 2001.
A.the United States will possibly still be a great food exporting nation
B.food exports will be forced upon the US to settle the population crisis
C.American agriculture will have to change its present way of food production
D.food price is likely to decrease with the increasing use of !unnatural food"
36、The Kurzweil Reading Machine。The first paragraph of the text discussed the u____of computers. The Kurzweil machine consists of three components: a scanner, a computer, an d a voice synthesizer. These three parts are like your eyes, your brain, and you r voice. The scanner is the !eye" of the machine. It scans, or looks at, the wo r ds on the page of a book and changes them into digital signals. These digital si gnals then go to the computer, the !brain" of the machine. The computer analyze s the signals and r***gnizes the words. The computer sends information about the words to the voice synthesizer. The voice synthesizer makes the sounds of the wo rds. To use the machine, a blind person simply opens the book and puts its face d own on the scanner (like a photocopy machine). The machine !reads" the words on the page. When one page is finished, the blind person turns the page and puts th e book on the scanner again. The Kurzweil machine can read in a normal voice or in a special fast voice. It can read words with small letters, large letters, or italics. Blind people like the Kurzweil machine because they can !read" anything wit h it: newspapers, magazines, books, even typed letters. Many libraries now have K urzweil machines for blind people to use. The Kurzweil machine can also help sig hted children learn to read. Can the Kurzweil Reading Machine help you to read in English? The computer c an analy{e the grammar of sentences, and the voice synthesizer can make the soun ds of the words. However, the machine cannot explain the meanings of the words. To use the machine, you must know the meanings of the words and sentence first.
37、(见36题)The Kurzweil machine read can read in a n____voice or a fast voice.
38、(见36题)The blind people like the Kurzweil machine because they can r____anything with it.
39、(见36题)The author writes this text to e____how the Kurzweil machine work.
40、(见36题)Clearly the text is writer for b_____people.
