GRE阅读最难的题型:逻辑题的套路大解密!

作为GRE阅读中公认最难的题型,逻辑题一直让很多同学头疼不已。

拿到逻辑题,很多同学下意识的做法就是排除法:把每个选项带入原文,反复比较,半蒙半猜做出最后的选择。

”这种做法显然速度很慢,而且最关键的正确率很低

这篇文章里,北美GRE代考网将以削弱题为例,教你摆脱排除法,主动阅读加预判答案做对逻辑题

例如:

· Which of the following, if true, most seriously weaken the argument given?

· Which of the following, if true, most seriously undermines the proposed explanation?

做削弱题(和多数逻辑题)的主动阅读的核心是,找准原文的结论

在削弱题中,原文的结论会有两种情况:

01

· 归因式结论:

· 归因式结论:某个结果的发生是因为某个原因。

例如:阅读机经300篇的第229篇:

Between 1970 and 1980, energy consumption by United States industry peaked and then declined, so that by 1980 total industrial use of energy was below the 1970 level even though total industrial output had grown substantially in the same period. Industry must have instituted highly effective energy conservation measures in those years to have achieved such impressive results.

02

· 预测式结论:

· 预测式结论:因为某个原因,所以会发生(发生过)某个结果。

例如:阅读机经第32篇:

Princessfish are a species of coral-reef fish that are captured alive by divers who first stun the individual fish by squirting a certain poison at them. Since the divers limit their catch to a few individuals and take care not to overfish, the divers’ continuing activities will clearly not result in serious harm to populations of princessfish.

区分了结论之后,削弱题的答案是完全可以在不看选项的情况下预判方向的。

不管是哪种削弱题,正确答案的共性都是“列举他因”,但之所以要把题目分成两类是因为在列举他因时的方向不同:

归因式结论的题目

1. 归因式结论的题目是“承认结果,列举他因”,即“原文的结果不是因为题目说的原因,而是别的原因”

以229篇为例,正确答案一定符合“工业用电下降不是因为业界采用了节能方法,而是因为(正确答案内容)”。

这题的正确答案:

The industries whose production dropped sharply during the 1970’s included a disproportionately large number of energy-intensive industries.“因为耗能工业的生产剧烈下降,所以工业用电下降”正符合这种列举他因的思路。

预测式结论的题目

2. 预测式结论的题目是“否定结果,列举他因”,即“原文的结果不会发生,因为其他的原因”

以32篇为例,正确答案需符合“princessfish会受到严重伤害,原因是(正确答案内容)”。

这题的正确答案:

Traces of the poison that remain in the seawater damage the Corals that create and maintain the reefs on which princessfish depend.

“因为捕鱼释放的毒素会留在珊瑚中,所以princessfish会受到严重伤害”也完美符合这种思路。
