42、aterandmakepower. B. Howdocsithappen? C. Itusedtocarry32billionm3ofwaterayear. D. Butnowithasaseriousproblem. E. Globalwarmingismakingthingsworse. 【答案】DCBAE 【解析】试题分析：每年的3月20日是世界水日。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。造成这一现象主要是由于筑坝和全球变暖导致河流干涸。 18. 句意：但是现在它有•个非常严重的问题。根据前文讲到黄河是第五大河流，灌溉着•些最古老的土地,后面却提到黄

43、河源头的青藏高原正在干涸，过去35年里的大部分时候都没有流入海里，可知这里需要-个表转折的过渡句，D项最合适。 19. 句意:过去的水流量是320亿立方米。根据后面一句NowitisdowntoZbillionin'orso可知,C项的44Itusedtocarry...”形成对比。 20. 句意：它是如何发生的呢？前文提到世界各大河流出现的问题，下文乂根究出现这些问题的原因，因此这里承上启下式地提出“为什么会出现以上这些现象？"的话题，B项最合适。 21. 句意：大坝为田地提供灌溉水源，还可以用来发电。此空前后讲述水坝（dam）的的作用，因此选A合适。 22. 句意：全球变暖使小情变

44、得更糟。后面是讲述全球变暖所带来的影响，所以该句是提出“全球变暖（Globalwanning）”这一现象。答案为E。 三、短文填空1 UnusualFestivals Everycountryhashisownfestivalstocelebratedifferentthings.Somefestivalsaremoreinteresting（hanothersbecausethey'reunusualandalotmorefun!Herearejustafewunusualfestivalsaroundtheworld.
