Without the atmosphere there would be no weather, no wind, rain, snow, or clouds. Air is all around us; we live at the bottom of a great ocean of air. It is invisible, but we can feel it when it moves. There are miles of air above us, pressing down with great weight on the earth and everything on it. Because air presses down on us from all directions at the same time, and because we are able to bear (忍受) this weight, we do not seem to feel it. But scientists have proved that air has this weight, and that anything that has weight creates(产生) a force called pressure. As changes in air pressure take place, they, make air move.

Air is a gas that expands(膨胀) when heated, gets lighter, and moves upward. When air is cooled, it gets heavier, sinks close to the earth's surface, and flows like water in a great river. As warn air rises, cold air rushes in to take its place. 'Thus winds originate (起源). The winds that blow high above us are caused by the warmer air running away from colder air. The wind we feel near the earth's surface is the heavy colder air trying hard to catch the warmer air. Changes in temperature cause the air to move. And of course there are many changes, so air movements are taking place practically all the time.

The first paragraph mainly tells us the causes of

A．why we don't feel air　　　　　　　B．why atmosphere is important to us

C．why there is air surrounding us　　D．why there is air pressure

Air moves under such conditions that

A．there is air pressure B．the air is heavy

C．air pressure doesn't remain the same all the time D．air comes up and down

Which of the following pictures best tells the movements of warm air and cold air?

According to the passage, in same areas if farmers who grow grapes (葡萄) light fires in the early morning, that is because the farmers want to________________．

A．drive away warm air B．prevent cold air from coming to harm their plants

C．cause more windD．stop warm air running away

The Grand Canyon (峡谷) in Arizona extends four hundred fifty kilometers. The canyons look as if they formed as the earth split apart. They were actually cut by rivers.
Looking at the Grand Canyon is like looking back in time. Forty million years ago, the Colorado River began cutting through the area. At the same time, the surrounding land was pushed up by forces deep within the Earth. Rain, snow, ice, wind, and plant roots rubbed away at the top of the new canyon. Below, the flowing river continued to uncover more and more levels of ancient rock. Their appearance changes endlessly -- with the light, the time of year, and the weather.
The Grand Canyon has several weather environments. The top is often much different from the bottom. On some winter days, for example, you may find cold winds and snow at the top. But at the bottom, you may find warm winds and flowers.
The Grand Canyon is known as one of the seven wonders of the natural world. About five million people visit the canyon each year. Most visitors walk along paths part way down into the canyon. Some visitors ride mules to the bottom and back.
There are several other ways to visit the Grand Canyon. Hundreds of thousands of people see the canyon by air each year. They pay a helicopter or airplane pilot to fly them above and around the canyon.
About twenty thousand people a year see the Grand Canyon from the Colorado River itself. They ride boats over the rapid, rocky water. These trips last from one week to three weeks.
Visitors can see the Grand Canyon in still another way. A huge glass walkway, called the Skywalk, extends from the edge and is hanging above the bottom of the canyon.
Some people say the Skywalk is an engineering wonder. However, other people have criticized the Skywalk and future development. They say it harms a national treasure and reduces the enjoyment of nature in the Grand Canyon.

A. the Grand Canyon is the most beautiful place in America

For every five men in the Civil War who died in battle , two or three died of disease. Doctors of that time knew very little about causes of sickness or ways of preventing it. Thousands of men in poor health became soldiers. Many of them could not resist epidemic （瘟疫）diseases that went through the places where they lived .
Army life was hard. Soldiers got little fruit or vegetables. There was no milk unless they happened to find a cow. Neither their clothes nor their living places protected the troops from rain, snow, and cold . Sickness and disease were spread by insects , rats , and unclean drinking water . Often the men drank straight from muddy streams .
Gunshot wounds were serious, as in any war, but they did not cause as many deaths as disease did.
1. Disease caused ___.
A．only a few deaths B．fewer deaths than wounds did
C．more deaths than wounds did   D．both A and B
2．Men who were accepted as Civil War soldiers were ______.

A．destroyed food B．carried diseases
C．made the water unclean D．tore the soldiers' clothes into pieces
5．The best title for this selection is ______.
A．The Cause of Disease B．The Greatest Danger in the Civil War
C．Insects, Rats, and Gunshot Wounds D．The History of Epidemic Disease

Our Future Homes

　What kinds of homes will we live the future? Nobody can be sure, architects, and scientists are new ideas now.

　　Some architects are thinking about whole cities under huge glass domes. Of course, complicated heating and systems will be necessary to control the climate in the domes. , there will never be any rain snow, and the temperature will be always .

　　Perhaps everyone will live in vertical（立体的） . High rises are so large that they can contain all the necessities of life. Since vertical cities will use land than horizontal cities, and provide homes for more people, they will be for small countries that have populations.

Another idea that will be helpful to countries (and island countries) is

the city. Monaco has already built homes, stores, and offices the water of the Mediterranean Sea. And a Japanese has made a plan for constructing buildings on bridges over Tokyo Bay.

　　There are some people who think we will go back to living in . But the caves of the future will be quite the caves of the Stone Age. Computers will control light and climate. Farms and parks will be on the land the cave city. When people want to go to the country or to a park, a short ride in will take them there.

The Beijing Olympic Torch boasts strong Chinese characteristics, and showcases Chinese design and technical capabilities. it embodies the concepts of a Green Olympics. a High-tech Olympics and the people’s Olympics.

The torch is 72 centimetres high, weighs 985 grams and is made of alumninium. The torch is of a curved surface form, with etching and anodizing being used during its production. A torch can usually keep burning for approximately15 minutes in conditions where the flame is 25 to30 centimetres high in a windless environment . The torch has been produced to withstand winds of up to 65 centimetres per hour and to stay aright in rain up to 50mm an hour. The flame can be identified and photographed in sunshine and areas of extreme brightness. The fuel is propane(丙烷) which is in accordance with environmental guidelines. The material of its form is recyclable.

The torch of the Beijing Olympic Games has a very strong Chinese flavor. It demonstrates the artistic and technical level of China. It also conveys the message of a Green Olympics, a High-tech Olympics and the people’s Olympics. The shape of the paper scroll and the lucky clouds graphic, express the idea of harmony. Its stable burning technique and adaptability to the environment have reached a new technical level. The torch of the Beijing Olympic Games is designed, researched and produced in China. BOCOG owns all intellectual property rights.

Under the concept of a Green Olympics, environmental protection was a key element listed in me in the invitation documents to the design companies by BOCOG. . The fuel of the torch is propane, which is a common fuel which also comes with a low price. It is composed of carbon and hydrogen. No material, expect carbon dioxide and water will remain after the burning, eliminating any risk of pollution.

Its stable burning technique and adaptability to the environment have reached a new technical level. It can stay alight in severe weather conditions such as strong wind, rain, snow, hail etc. It can also be identified in sunshine and areas of extreme brightness so as to satisfy the requirements of capturing photographic images and video footage.

2005 August BOCOG developed the design concepts and requirements the torch.

2005 December BOCOG recruited potential torch designs from the design society. In total, BOCOG received 388 pieces of works.

2006 June--August BOCOG selected the structural designer and the burning

system designer.

2007 January Beijing Olympic Torch was approved by IOC.
