As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air ,It also collects bits of dust and microbes(微生物)that are floating in the air, When the rain reaches the ground it begins to pick up more dust and dirt, Many kinds of mineral substances dissolve in the water ,Sand and nud cannot dissolve in water.
Since water is so important to us, it is very important that the water we use should be clean , Otherwise, we might get some of the diseases that are carried by water Many microbes are harmful ,They are so small that we cannot see them ,These microbes must be removed or killed before the water is not clean, people who drink this water may get these diseases, Thus , to provide people with clean water, the government purifies the water.
Purification is a long process and consists of three stages: storing ,purifying and distributing ,The first stage is storing , Man-made lakes called reservoirs are used for this purpose ,Water from the rains ,other lakes, streams and rivers is collected in the reservoirs ,This water is usually dirty and muddy.
In the second stage shich is purifying , water from the reservoirs is filtered in a special pond, Stones, sand and other unwanted tiny things are caught in it, After that, tiny microbes are still present in the water ,These microbes are removed by “airing ”the water and by adding a chemical substance called chloring(氯)to the water ,This kills all the microbes in the water ,A fter this the water can be safely used for drinking.
The third stage is the distribution of the purified water to homes ,hospitals, offices ,factories and other places, This is done through a network of pipes of various sizes, These pipes must be make of a suitable material.

The followingpassage is a healthy prescription (处方) of how we can approachlife. It is not about being famous or being wealthy or aboutourgoodlooks. Truly,it is all about love. There are times when we feel as if we are separated from the rest. This feeling creates a mental prison. Therefore,we should try to work hard tointernally (内在地)liberate ourselvesby widening our circle of pity to accept all living things.
“Open your heart to others andtry to understand,
When someone reaches for you, hold out to them your hand,
Follow your heart,nomatter what otherpeople say,
Do things that make you able to smile throughout your day,
Treat other people, the way you would like them to treat you,
Do what you know is right andto your heart and self stay true,
Remember what life isall about, it is how you make people feel,
What you do, where you go, and making dreams become real,
Helping people through, in hard times of pain and strife,
What you do for others, is what is important in this life.
Look deeper anddon’t judge people by what ison the outside,
It iswhat is inside that counts and what people often hide,
Care, help, love, be honest, and be kind,
Withpurity and goodness within yourself,it ishappiness you willfind.
Do all you can in the time you have, you won’t always be around,
Recapture the joy of little things, that once were easily found,
And if you can do all this and live a life of love,
You willbe helped through life, by all those up above.”

Tess still stood hesitating like a swimmer about to make his dive, hardly knowing whether to return or move forward, when a figure came out from the dark door of the tent. It was a tall young man, smoking.
He had an almost black face, though red and smooth. His moustache was black with curled points, though he could not be more than twenty-three or-four. There was all unusual force in his face, and in his daring rolling eyes.
“Well, my beauty, what can I do for you?” said he, coming forward. And seeing that she was quite at a loss: “Never mind me, I am Mr. d’Urbervilles. Have you come to see me or my mother”
This differed greatly from what Tess had expected. She had dreamed of an aged and dignified face. She tried to keep calm and answered-“I came to see your mother, sir.”
“I am afraid you cannot see her-she is ill in bed,” replied the representative of the house; for this was Mr. Alec, the only son of the noble family. “What is the business you wish to see her about?”
“It isn’t business-it is-I can hardly say what.”
“Pleasure”
“Oh no. Why, sir, if I tell you, it will seem…”
Tess’s sense of a certain ridicule was now so strong that despite her general discomfort at being here, her rosy lips curved(弯曲)towards a smile, much to the attraction of the young man.
“It is so foolish,” she stammered(结结巴巴地说); “I fear I can’t tell you”
“Never mind; I like foolish things. Try again, my dear,” said he kindly.
“Mother asked me to come,” Tess continued, “and, indeed, I was in the mind to do so myself. But I did not think it would be like this. I came, sir, to tell you that we are of the same family as you.”
“Ho! Poor relations!”
“Yes.”
“Stokes”
“No; d’Urbervilles.”
“Ay, ay; I mean d’Urbervilles.”
“Our names are worn away to Durbeyfield; but we have several proofs that we are d’Urbervilles. The local scholars hold the view that we are, …and…and we have an old seal(印章)and a silver spoon marked with the same castle as yours. So mother said we ought to make ourselves known to you, as we’ve lost our horse by a bad accident; we can hardly make a living.”
“Very kind of your mother, I’m sure.” Alec looked at Tess as he spoke, in a way that made her uneasy. ”And so, my pretty girl, you’ve come on a friendly visit to us, as relations.”
“I suppose I have,” looking less confident and uncomfortable again.
“Well—there’s no harm in it. Where do you live? What are you?”
—Tess of the d’Urbervilles By Thomas Hardy
67. How does Tess feel in the whole course of the meeting with Alec?
A. Excited and hopeful B. Nervous and uncomfortable
C. Surprised but comfortable D. Pleased but embarrassed
68. In the eyes of Tess, Alec is ________.
A. forceful and daring B. unfriendly and talkative
C. a gentle and reliable man D. older than she had expected
69. Why does Tess pay the visit to the d’Urbervilles?
A. To see Alec himself.
B. To see Alec’s mother.
C. To confirm that they are of the same family.
D. To make known their relationship and seek help.
70. Alec appears quite friendly to Tess mainly because ________.
A. Tess is his distant relationB. Tess looks polite to him
C. Tess is a pretty girl D. Tess looks ridiculous


Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺桨)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋风片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind
63. According to the passage, which of the following statements is true?
A. The rotating blades can kill as many birds as high-rise buildings do
B. Single families are not encouraged to build turbines.
C. The USA produces more wind power than any other country in the world.
D. The noise the turbines make may discourage people from building them.
64. The underlined word “generator” in the third paragraph probably means_______.
A. 电动机 B. 发电机 C. 机翼 D. 飞机引擎
65. If the USA wants to build wind turbines in an area with 30,000 homes, how many
should they build at least?
A. 50. B. 150. C. 250. D. 200.
66. All the following are the advantages of wind energy EXCEPT that_________.
A. it is environmentally friendly B. it is free to build and operate
C. the government supports it D. the energy is clean and renewable


The United States will introduce a new and comprehensive(综合的) exam for students who seek to study in American and other English-speaking countries, Xinhua News Agency reported from New York.
The exam, which stands for a great change from the current English level test, was disclosed by Theresa Chang Wei Jen, associate director of the International Service of the US College Board, America’s leading educational organization.
The Advanced Placement International English Language (APIEL) will be offered for the first time throughout the world, said Jen.
However, the APIEL is a strange title to most Chinese students, and it is unlikely to soon gain the similarity of other already existing exams, such as the TOEFL(Test of English as a Foreign Language), the GRE(Graduate Record Examination), or the IELTS(International English Language Testing System).
“I have never heard of such a test and I would prefer the IELTS if I need another exam,” said Xu Jingyan, a graduating student from Beijing University of Aeronautics and Astronautics, who wants to study in England and has already taken the TOEFL.
Most of Xu’s classmates have never heard of the APIEL. “The APIEL is designed for international students who wish to get university studies in English-speaking countries, including the United States, Britain, Canada, and Australia.” said Jen.
The APIEL has been adopted, said Jen, because the TOEFL can no longer accurately reflect the abilities of students of using the English language comprehensively in an academic environment. Xinhua reported that a fairly large number of foreign students who earned high scores in TOEFL exam turned out to be very ordinary educational performers after admission.
Compared with the TOEFL, the APIEL measures a student’s ability to read, write, speak and understand English through testing his or her skills in listening comprehension, speaking with accuracy(精确) and resourcefulness, and writing with clarity and fluency(流畅), Jen said.
60. The United States will introduce a new exam because _______.
A. it will bring the US government quite a lot of money
B. the Chinese people pay special attention to English studies
C. the already existing exam systems seem to be far from perfect
D. more and more students want to get further education in the USA
61. Which of the following statements is TRUE according to the selection?
A. The TOEFL is more popular with the Chinese than the IELTS.
B. It will take quite a period of time for people to accept the APIEL.
C. Chinese students will prefer the IELTS rather than the APIEL even in the future.
D. A student will have to take the APIEL if he or she wants to study in English-speaking
countries.
62. The best title for this news report is_____.
A. New Exam Designed for Students B. The Key to Improving Your English
C. TOEFL, IELTS and GRE to be Out of Date D. The Four Skills in Learning English


第三部分阅读理解(共15小题;每小题2分,满分30分)
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
Fifty years from now the world’s population will be declining, with no end in sight. Unless people’s values change greatly, several centuries from now there could be fewer people living in the entire world than live in the United States today. The big surprise of the past twenty years is that in not one country did fertility (生育能力) stop falling when it reached the replacement rate(出生率)—2.1 children per woman. In Italy, for example, the rate has fallen to 1.2. In Western Europe as a whole and in Japan it is down to 1.5. The evidence now indicates that within fifty years or so world population will peak at about eight billion before starting a fairly rapid decline.
Because in the past two centuries world population has increased from one billion to nearly six billion, many people still fear that it will keep “exploding” until there are too many people for the earth to support. But that is like fearing that your baby will grow to 1,000 pounds because its weight doubles three times in its first seven years. World population was growing by two percent a year in the 1960s; the rate is now down to one percent a year, and if the patterns of the past century don’t change completely, it will head into negative numbers. This view is coming to be widely accepted among population experts, even as the public continues to focus on the threat of uncontrolled population growth.
As long ago as September of 1974 Scientific American published a special issue on population that described what demographers (人口统计学家) had begun calling the “demographic transition” from traditional high rates of birth and death to the low ones of modern society. The experts believed that birth and death rates would be more or less equal in the future, as they had been in the past, keeping total population stable after a level of 10-12 billion people was reached during the transition.
56. Which of the following statement is NOT true according to the passage?
A. The world’s population in the future will be reducing endlessly.
B. When the earth population reaches 8 billion, it will see a rapid decrease.
C. In modern society the birth and death rates will be more or less equal in the future.
D. The public now pay little attention to the threat of uncontrolled population growth.
57. What’s reason for the sharp increase of world population in the past two centuries?
A. Because people fear that the world will explode.
B. Because the world’s replacement rate keeps falling.
C. Because people’s values has greatly changed.
D. The passage doesn't mention it.
58. The expression “demographic transition” (Paragraph 3) probably means _______.
A. high death rate to the low one
B. high birth rate to the low one
C. high rates of birth and death to the low ones
D. low rates of birth and death to the high ones
59. We can learn from the passage that _______.
A. in the near future there will be a rapid decline of the world population
B. the birth and death rates of modern society will be unequal in the future
C. there would be the same population living in the world than it in the US today
D. in Western Europe the replacement rate has declined to a negative number
