On June 17, 1774, the officials from Maryland and Virginia held a talk with the Indians of the Six Nations. The Indians were invited to send boys to William and Mary College. In a letter the next day they refused the offer as follows:

    We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you. We are sure that you mean to do us good by your proposal（提议）; and we thank you heartily. But you must know that different nations have different ways of looking at things, and you will therefore not be offended（冒犯） if our ideas of this kind of education happen not to be the same as yours. We have had some experience of it. Several of our young people were formerly brought up at the colleges of the northern provinces: they were taught all your sciences; but when they came back to us, they were bad manners, ignorant（无知的）of every means of living in the woods–they were totally good for nothing.

  　We are, however, not the less thankful by your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send us a dozen of their sons, we will take care of their education, teach them in all we know, and make men of them.

The tone(语气) of the letter as a whole is best described as________.

A. angry          B. pleasant            C. polite          D. ambitious

The Indian chief’s purpose of writing the letter seems to be to ____.

   A．politely refuse a friendly offer            B．express their opinions on equal treatment

   C．show their pride                D．describe Indian customs

According to the letter, the Indians believed that ____.

   A．it would be better for their boys to receive some schooling

   B．they were being insulted by the offer

   C．they knew more about science than the officials

   D．they had better way of educating young men

Different from the officials’ view of education, the Indians thought ____.

   A．young women should also be educated

   B．they had different goals of education

   C．they taught different branches of science

   D．they should teach the sons of the officials first

　　BBC(May 11,2008) - Edinburgh Zoo makes plans to bring a pair of giant pandas from China to Scotland.Zoo representatives recently returned from China,where they signed a letter of intent(意向书) making a promise to bring giant pandas to Edinburgh.
　　It's been suggested that a breeding pair should be on loan(暂借) to the Royal Zoological Society of Scotland(RZSS) for 10 years.It is hoped that they would give birth to cubs during that time.Edinburgh Zoo would be only the eighth Zoo in the Western hemisphere(半球) to care for the species if the project goes ahead.
　　Zoo chiefs said that looking after the endangered animals could benefit conservation.David Windmill,chief executive of RZSS,said,"Working with giant pandas means so much more to us than introducing a new species to our collection.It's an opportunity to work on a global level with other conservationists to gain a better understanding of giant pandas,the threats they face,and what we can do to ensure their survival."
　　At present there're only around 1,500 giant pandas in the wild.RZSS has been working on the project for almost a year,and hopes to have giant pandas at Edinburgh Zoo by 2009 ,the year of the society's centenary(一百周年纪念日).
　　Mr.Windmil said that the project had received strong support from the UK and the Scottish government and that this must continue if the zoo was to reach an agreement with the Chinese.As part of the proposed agreement with the Chinese government,Edinburgh Zoo will collaborate(合作) on research projects benefiting conservation in the wild.
　　RZSS will also provide considerable money to support giant panda conservation projects in the wild.Giant pandas live in a few mountain ranges in central China and feed almost only on bamboo,which makes up 99% of their diet.
　　68.What is the best title for the passage?
　　　A.Edingburgh Zoo does research into giant pandas.
　　　B.Giant pandas live happy at Edinburgh Zoo.
　　　C.Edinburgh Zoo expects giant pandas from China.
　　　D.Scotland supports giant panda conservation.
　　69.If Edingburgh Zoo can borrow giant pandas,what will happen?
　　　A.RZSS will have a better understanding of living habits of giant pandas.
　　　B.RZSS will celebrate its centenary in 2009.
　　　C.Scotland will be the eighth country to have giant pandas.
　　　D.Edinburgh Zoo will be the eighth zoo to have giant pandas in the world.
　　70.At present what seems to be the key factor for giant pandas to successfully go to Edinburgh Zoo?
　　　A.RZSS's attitude.
　　　B.The Scottish government's attitude.
　　　C.Edinburgh Zoo's support.
　　　D.The Chinese government's attitude.

　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
　　　A.mean a warming - up im the Arctic
　　　B.raise the temperature of the earth's surface
　　　C.prevent the sun's rays from reaching the earth's surface
　　　D.account for great changes in the climate in the northern hemiphere
　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
　　　A.mainly because the levels of carbon dioxide are rising
　　　B.partly due to variations in the output of solar energy
　　　C.possibly because the ice caps in the poles are melting
　　　D.exclusively due to the effect of the inertia of the earth's climate
　　70.On the basis of their models,scientists are of the opinion that ________.
　　　A.the climate of the world should be becoming cooler
　　　B.the new Ice Age will be delayed by the greenhouse effect
　　　C.the man - made warming effect helps to increase the solar effects
　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

Our surroundings are being polluted faster than nature and man’s present efforts cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.

What can explain and solve this problem? The fact is that pollution is caused by man — by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.

Isn’t it time we stopped to ask ourselves where we are going — and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.

2. People crowd into the cities because ______.

　 A. they want very much to find well-paid jobs

　 B. they are anxious to enjoy the achievements of our society

   C. they have become tired of their homeland

   D. they have a strong wish to become industrial workers

3.According to the passage, what does man value most?

   A. Industry.                                                 B. Health.   

   C. Clean air.                                         D. The future of the children.

4.The story about the airline pilot tells us that ______.

   A. man knows where the society is going

   B. people do not welcome the rapid development of modern society

   C. man can do little about the problem of pollution

   A. With the development of technology, pollution has become a serious problem.

   B. Lower the speed of development to stop pollution.

   C. It’s time we did something to reduce pollution.

   D. As industry is growing fast, pollution is the natural result.
