Stepping into a pool of water is common enough, but who could ever imagine stepping into a pool of fish? In February of 1974, Bill Tapp, an Australian farmer, saw a rain of fish that covered his farm. How surprised he must have been when he heard many fish hitting against his roof!

　　 What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a combination of wind and storm.

　　When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners, collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before dropping them on fields, houses, and astonished people.

　　Although they seem unusual, fish-falls occur quite frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as common as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.

　　56. What is this passage about?

　　A. A sad story. 　　　　　　　　　　　　B. A rain of fish.

　　C. Australia’s northern part.　　　　　D. The damage done by floods.

　　57. Fish-falls occur in Australia_________ .

　　A. quite often 　　　　　　B. on large farms

　　C. only in winter　　　　　D. when the air is calm

　　58. It is a known fact that ________.

　　A. one should watch where one steps

　　B. Bill Tapp is a scientist who studies farming

　　C. the natural world can never create waterfalls that fall upward

　　D. the seasons in the southern part are different from those in the northern part

　　59. The word “infinite” is closest in meaning to _________.

　　A. easy 　　　B. difficult 　　　C. countless 　　　D. dangerous

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
