其实不管我们备考的是GRE，托福，还是雅思或者SAT考试，或者考哪个科目，都离不开逻辑。可以说万物皆逻辑。所以，如果能搞清楚逻辑那题目就引刃而解了。
总的来说逻辑判断就是两种，两个句子之间是取同还是取反：如果有however等转折的话，那前后两个句子就是内容相反的。比如，lulu教书不错，但是，....那但是后面一定是不好的内容，比如，但是她性格不好。
1. 我们先来感受一下托福阅读中的词汇题
The interaction of improved processing and high demand led to the rapid spread of cultivation of cotton and to a surge in production.
The word surge in the passage is closest in meaning to ___
A. sharp increase
B. sudden stop
C. important change
D. excess amount
【解析】从文章中我们可以看出是一个因果关系加并列关系：A led to B and C（B是rapid spread of cultivation of cotton the and C是to surge in production. 通过and并列关系逻辑取同，那surge就等于前面rapid spread的意思啦！那答案就很容易选啦A.
接下来我们就看看通常见到的逻辑有哪些？
2. 我们再来看看句子插入题的句间逻辑
Paragraph 5: █Modern architectural forms generally have three separate components comparable to elements of the human body; a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body’s vital organs and systems. █The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. █Of course in early architecture—such as igloos and adobe structures—there was no such equipment, and the skeleton and skin were often one. █
However, some modern architectural designs, such as those using folded plates of concrete or air-inflated structures, are again unifying skeleton and skin.
【解析】我们来看看这个要插入的句子，很明显这里是有However，是一个转折逻辑，也就是前后是取反的逻辑。那我们通过however后的内容some modern architectural design预测前面的内容应该是说的早期的或者原始的architectural design；那答案就很容易选出来啦，第三句讲的early architecture；那就放在第三句后面。
3. 那大家错误率的推断题怎么用逻辑来解决
Forehead rubbing by male deer on buck rubs presumably sends a great deal of information to other members of the same species. (论点句）First，the chemicals deposited on the rub provide information on the individual identity of an animal; no two mammals produce the same scent. For instance, as we all know, dogs recognize each other via smell. Second, because only male deer rub, the buck rub and its associated chemicals indicate the sex of the deer producing the rub. Third, older, more dominant bucks produce more buck rubs and probably deposit more glandular secretions on a given rub. Thus the presence of many well-marked rubs is indicative of older, higher-status males being in the general vicinity rather than simply being a crude measure of relative deer abundance in a given area. The information conveyed by the olfacotry signals on a buck rub make it the social equivalent of some auditory signals in other deer species, trumpeting by bull elk.(TPO28 Buck Rubs and Buck Scrapes)
What can be inferred from paragraph 4 about the trumpeting of bull elk?
A. Trumpeting by higher-status bull elk signals their presence to other members of their species.
B. Bull elk need to combine trumpeting with olfactory signals to convey information about their identity.
C. Trumpeting alerts white-tailed deer to the presence of bull elk in their vicinity.
D. Trumpeting provides a better measure of deer presence in a given area than buck rubs do.
【解析】我们很容易根据题干的trumpeting of bull elk 定位到文章的最后一句，但是当你看最后一句，你发现做不了这个题目。最后一句说的是由嗅觉传递的信息和听觉传递的信息是social equivalent的。那什么是social equivalent呢？根据整个段落的逻辑结构，这个段是一个标准的总分，句是论点，后面并列说了3个传递的信息。那最后一句是支持第三个小分论点的，所以就是取同的逻辑，也就是支持论点（传递higher-status的信息）。那答案就显而易见了，就是A。
