Every year there are changes in climate in different parts of the world. Some of these changes are due to natural causes. However, some climate changes are caused by air pollution and these changes may increase.

If the pollution affects the level of carbon dioxide in the atmosphere, the results are likely to be serious. Carbon dioxide has only a small part of the atmosphere. But it has an important function in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the Earth. Some of the radiation is absorbed by the Earth and some is radiated back into the atmosphere. The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere. Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the Earth from falling.

If the proportion of carbon dioxide in the atmosphere is increased as a result of air pollution, the temperature of the atmosphere may rise. This might cause the ice in the North and the South to melt. If this happened, the sea level could rise and parts of the Earth would be flooded, this happening is not quite likely but the possibility exists.

There is also a fairly strong possibility that the dust level in the atmosphere will rise as a result of industrial pollution. This dust pollution will reflect sunlight back into space. If this happens less sunlight will reach the Earth and the temperature will fall.?

Another danger comes from the destruction of the Earth's vegetation(植物)such as the forests of Brazil, which are being cleared away for farmland and cities. Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere.

1. The main purpose of this passage is to tell us that_____.

A. the climate of the world is always changing

B. air pollution has greatly affected the climate of the world

C. carbon dioxide has something to do with climate dangers

D. climate of the world is subjected to(使受到)dangers from air pollution

2.From this passage we learn that carbon dioxide_____.

A. helps to prevent the temperature of the Earth from rising

B. keeps much of the sun's radiation from entering the atmosphere

C. plays an important part in keeping the balance of the temperature of the Earth

D. is one of natural causes of climate changes

3.Judging from this passage, if the level of carbon dioxide in the atmosphere went down, the temperature of the Earth would_____.

A. Become higher    B. either rise or fall

C. become lower    D. neither rise nor fall

4.Which of the following is not the possible serious outcome of air pollution related to climate changes?

A. Parts of the Earth would be flooded one day.

B. Less sunlight would reach the Earth.

C. The temperature of the Earth might rise.

<

D. The Earth's vegetation might be destroyed.

Everyday, 340 million people speak it. One billion people are learning it and it is said that by 2050, half of the world’s population will be using it. What are we talking about? That is the global language—English.
The English language started in Britain in the 5th century. It is a mixed language. It was built up when German. Scandinavian and French invaders settled in England and created a common language for communication.
Today it is the official language of the UK, the USA, Australia, New Zealand, Canada, South Africa and Ireland as well as many islands in the Caribbean. Many other countries and regions use it for politics and business, for example, India. Pakistan, Nigeria and the Philippines. English is also one of the official languages of Hong Kong.
But global advertising and pop music mean that in most countries, you will see or hear some English. Thanks to McDonalds, we all know about “burgers”. “fries” and “milkshakes”. Songs by Madonna, Britney Spears and Celine Dion are in English. We can sing along, even if we do not understand what we are singing!
English is a messy (杂乱的) language. Every year, dictionaries include new words that talk about popular culture, for example, computer-related words such as "blogging", "download" and "chartroom". Also included are words that teenagers use. Who does not know “cool”, “OK” and “hello”?
Other languages also influence English. Many English words come from French. Words like “café” and expressions like “c'est la vie” (that is life) are all part of the English language. On the other hand, the French language includes English words like "le weekend" and "le camping". German words are also part of English. Words like "kindergarten" come from the German language.
Recently, British people have become interested in “yoga”. But the word comes from an ancient Hindu language in India.

This is a dangerous world we live in. The numbers of murders goes up every year； people are dying of cancer；more people contract（感染）HIV；more teens are using drugs；etc. You know this because you’ve heard all the statistics on the news. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background, statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous.
For example, several years ago a high school student reported dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors（肿瘤）， is found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening strike. When you think about it, skiing is more dangerous than you might at first think when looking at statistics. If we teenagers are to be left in this world, we had better be able think critically, and form our own views. rather than be easily persuaded by another’s. To be warned is to be prepared.
59．In the first paragraph, what problem does the writer want to warn us?
A. We are now living in a dangerous world.
B. We got a lot of false statistics from the media.
C. There are around us more and more murders, diseases etc.
D. Statistics alone without full background don’t give us an accurate picture of things.
60．Why does the writer use the example in the second paragraph?
A. To show the danger of reporting only part of the information.
B. To argue that high school students are easily persuaded.
C. To prove what is necessary to us might be dangerous.
D. To warn us of the harmful substances（物质）around us.
61．Relative information is often left out because      .
A. relative information is not that important
B. the author is trying to show what he or she says is true
C. too much information will make readers feel confused
D. readers are not able to analyze so much information at once
62．What is the main idea of this passage?
A. Some measures must be taken to protect our dangerous world.
B. We should learn to think critically and look at problems from all sides.
C. The growing trend of reporting only half-truths is getting out of control.
D. Teenagers ought to improve their ability of telling right from wrong.

Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.
But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.
Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.
“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological（生态的） disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.

For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.

However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.

Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.

A phosphate mine is not a hole in the ground; it is a strip mine（带状矿）. When a company strip-mines, it removes the top layer（层） of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.

In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.

Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.

1.What might be the author’s purpose in writing the text?

A. To seek help for Nauru’s problems.            B. To give a warning to other countries.

C. To show the importance of money.            D. To tell a heartbreaking story of a war.

2.What was Nauru like before the Europeans came?

A. Rich and powerful.                        B. Modern and open.

C. Peaceful and attractive.               D. Greedy and aggressive.

3.The ecological disaster in Nauru resulted from           .

A. soil pollution                                B. phosphate over mining

C. farming activity                        D. whale hunting

4.Which of the following was a cause of Nauru’s financial problem?

A. Its leaders misused the money.           B. It spent too much repairing the island.

C. Its phosphate mining cost much money.    D. It lost millions of dollars in the civil war.

5.What can we learn about Nauru from the last paragraph?

A. The phosphate mines were destroyed.          B. The leaders will take the experts’ words seriously.

C. The island was abandoned by the Nauruans.     D. The ecological damage is difficult to repair.
