分析 每年的3月20日是世界节水日.根据美国的一个报道,世界上有一半多的主要河流严重缺水或被污染.黄河,世界上第五大河,在过去的35年里,就没有流到大海里.埃及的尼罗河,世界上最长的河流,由原来每年的32亿立方米的流量降低到20亿立方米.等等.是什么原因造成这样的现象?主要是由于筑坝和全球变暖导致河流干涸.
解答 66.答案:F.还原句子题,根据上文可知:黄河,世界上第五长河,浇灌了地球上最古老的一些农场,但现在它有一个严重的问题.这里介绍中国的河流情况.根据所给选项中Qinghai-Tibet Platean 可知这和中国的河流有关.意思为:青藏高原的源头快要干涸了.故选:F.
67.答案:C.还原句子题,根据上文介绍:尼罗河是世界上最长的河流.结合下文 Now it is down to 2billion m'or so.这里介绍尼罗河现在的水流量.根据所给选项C可知介绍了过去尼罗河的水流量,故选:C.
68.答案:D.还原句子题,根据上文可知介绍了三大著名河流的情况.结合下文Mostly it's damming (筑坝) and global warming that make rivers dry.这里介绍了导致河流干涸的原因.这里应该询问:它是怎样发生的,故选:D.
69.答案:A.还原句子题,根据上文可知:什么原因造成这样的现象?主要是由于筑坝和全球变暖导致河流干涸.下文应该介绍大坝的用途:它可以用来灌溉和发电.故选:A.
70.答案:B.还原句子题,根据上文可知:全球变暖使情形变得更糟.温暖的天气带走了水分,冰川正在变小.根据上文提到Its source on Qinghai-Tibet Platean is dying up可以推断出中国的黄河源头干涸也是全球变暖造成的.故选:B.
