问题     The sun’s heat warms the air and makes it move. This movement is called a wind. Different parts of the Earth receive different amounts of heat. Near the equator(赤道), the sun is overhead and heats the Earth intensely (强烈). Nearer the poles, the sun’s rays strike the Earth at a low angle so the heat is not so intense.
    A lot of the earth’s heat is reflected back into spaces, by the atmosphere, clouds, dust in the air and by water, snow and ice. So some parts of the Earth are warm and some are cold. Warm air tends to rise and creates areas of high pressure. As warm air rises, cold air flows in and replaces it. The greater the pressure difference is, the stronger the wind blows.
The best title of the article is______.

选项 A、The Sun’s Heat
B、Pressure
C、Atmosphere
D、Why Do Winds Blow

答案D

解析 本题考查的是对文章主旨大意的把握能力。标题反映文章大意,要求选项的归纳范畴恰如其分,既不能只提文章中的一个细节,犯理解过窄的错误,也不能将本文以外的内容概括于其中,犯理解过宽的错误。一般主旨题的解题方法有两个:(1)观察文章或段落的结构。(2)根据论述详略确定。通常与主题有关的部分有较详尽的论述,而与主题关系不够密切的部分论述较简略。
