3.Researchers and many scientists are concerned that the earth's climate and atmosphere are becoming warmer.What scientists do agree on is that the temperature will continue to increase if measures are not taken to reduce pollution and emissions(排放物) from cars and factories.
It is widely agreed that oil and coal create greenhouse gases.These emissions include carbon dioxide,which is the cause of most of the global warming problems.The loss of trees in many areas is making the problem worse,because trees and plants absorb carbon dioxide and release oxygen.The fewer trees that are left standing,the less carbon dioxide can be absorbed.
Scientists predict that the sea level will rise,ice caps will melt,and some animals and plants will fail to survive because their homes will disappear.There may be more deserts and less available farmland because of the dry ground,and there may be more storms and floods.
Some countries,including the UK and the US,are taking steps to prevent the situation from becoming worse.There are programmes to educate citizens and students about the situation and recycling waste is becoming more common.Using more alternative(替代的) energy sources is also a good way to prevent global warming.
One thing that everyone can do is limit their use of energy every day,and you can do this no matter how old,or young,you are.Try to limit the unnecessary use of electricity and work to save energy every day.

解答 66-70 CABBA
66 C 主旨大意題. 通讀全文可知本文主要介紹全球變暖趨勢日趨嚴重,要求我們采取行動組織全球變暖.故選C.
67 A 細節(jié)題. 根據(jù)文章第二 段It is widely agreed that oil and coal create greenhouse gases和The fewer trees that are left standing,the less carbon dioxide can be absorbed.可知造成全球變暖的原因是溫室效應和更少的樹木,故選A.
68 B 細節(jié)題. 根據(jù)文章第三 段 some animals and plants will fail to survive because their homes will disappear. 可知一些動植物因為全球變暖而消失,故選B.
69 B 細節(jié)題. 根據(jù)文章第四 段.There are programmes to educate citizens and students about the situation and recycling waste is becoming more common.Using more alternative(替代的) energy sources is also a good way to prevent global warming.可知一些國家組織全球變暖的手段沒有關閉所有工廠,故選B.
70 A 細節(jié)題. 根據(jù)文章最后一段Try to limit the unnecessary use of electricity and work to save energy every day.可知作者對全球變暖是關心的,故選A.
點評 做閱讀理解時要快速的瀏覽全文,把握文章主旨大意,帶著問題回到原文,尋找細節(jié)或概括相應的答案,最后要理清作者寫作思路.
