湛江雅思培训：雅思7 Test1 Reading One22

22.Feeding increasing populations is possible due primarily to improved irrigation systems.

参考译文：改良后的灌溉系统使我们得以养活越来越多的人口。

定位词：irrigation system／或者按照顺序原则定位在B段

解题关键字：possible

文中对应点：B段：Food production has kept pace with soaring populations mainly because of the expansion of artificial irrigation systems that make possible the growth of 40％ of the world＇s food．食品供应能跟得上人口猛增主要是由于人工灌溉系统的增长使得世界粮食产量提高了40％。

这是一道模范版的同义词对应型TRUE。TRUE的原则在这里显得很苍白，possible也显得英雄无用武之地。

题中的feeding increasing population在文中对应Food production has kept pace with soaring populations，题中的due primarily to变成文中的mainly because of，而题中的improved irrigation system则成了文中的expansion of artificial irrigation systems.

答案YES
