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 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 a force called pressure. As changes in air pressure take place, they, make air move.
Air is a gas that expands 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 warm air rises, cold air rushes in to take its place. Thus winds originate. 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.
1.The first paragraph mainly tells us ________.
[ ]
A.that there is air pressure
B.why air is invisible
C.why there is air around us
D.that there is air around us
2.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
3.Which of the following pictures best tells the movements of warm air and cold air?
[ ]
A.
B.
C.
D.
4.Why do farmers who grow fruit trees make fires in the early morning?
[ ]
A.To drive away warm air.
B.To prevent cold air from coming to harm their trees.
C.To cause more wind.
D.To stop warm air running away.
1.这是一道主旨大意题。该段首句意在说明大气层的重要性,接下来说的是空气无色但有重量,有压力,当各方压力相同时,我们就感受不到空气,但压力失去平衡就形成了空气的流动,于是为下段进一步描述空气流动作好了铺垫,所以选A项。 2.这是一道细节题。短文尾段尾句As changes in air pressure take place,they,make air more.表明,答案为C。 3.这是一道识图解意题。根据短文第二段首句可知,气体加热变轻向上流动,气体冷却变重像水一样往低处流动,所以B图正确。 4.这是一道推理判断题。根据短文前两句,冷空气像水一样向下运动可推断出,果农放火是为了驱赶冷空气,所以答案选B。 |
