GMAT逻辑题一直以来是不少考生的弱项,因为逻辑题考查的不只是考生对于英文题目的阅读和理解能力。考生必须具备一定的逻辑推理思维能力才能做好此类题目。下面小编就通过一些GMAT逻辑真题的完整分析来为大家讲解这一难点题型的解题思路和技巧。
例题分享:
Which of the following most logically completes the argument below?
Using broad-spectrum weed killers on weeds that are competing with crops for sunlight, water, and nutrients presents a difficulty: how to keep the crop from being killed along with the weeds. For at least some food crops, specially treated seed that produces plants resistant to weed killers is under development. This resistance wears off as the plants mature. Therefore, the special seed treatment will be especially useful for plants that__
(A) produce their crop over an extended period of time, as summer squash does
(B) produce large seeds that are easy to treat individually, as corn and beans do
(C) provide, as they approach maturity, shade dense enough to keep weeds from growing
(D) are typically grown in large tracts devoted to a single crop
(E) are cultivated specifically for the seed they produce rather than for their leaves or roots
题目类型:
complete the argument

用广谱除草剂除去与农作物竞争的杂草有一个问题:如何保证农作物不和杂草一起被消灭。对至少有一些农作物来说,经特殊处理的可以对抗除草剂的种子正在生产中,但这种对抗性在植物成熟之后就消失了。因此,这种特殊的种子适用于这样的植物:
解题思路:
对抗性在植物成熟之后消失,说明这种种子只能在幼年期保护植物,而在植物成熟之后需要植物自己保护自己。
逐项分析:
A、即使这种植物的成熟时间很长,但成熟了之后还是免不了受到杂草或者是除草剂的影响。
B、种子大是方便人类区分的,除草剂不会区分。
C、正确选项。如果植物在成熟之后可以自己抑制杂草生长,就不需要人工除草,也就让植物灭受除草剂的影响。
D、一片区域全是一种植物的情况。仍然会有杂草,需要除草剂。
E、种植这种植物是为了获得它们的种子,不是叶子或根。仍然会有杂草,需要除草剂。
正确选项:
C
