逻辑是托福阅读中的一大考点，托福阅读中很多题目在解答时都需要直接或者间接地用到逻辑关系。考生要熟悉托福阅读中逻辑的相关作用，熟悉托福阅读逻辑考点。前程百利小编通过相关示例为大家带来分析。
1.句子简化题考察考生对于句子内部逻辑的熟悉程度。比如TPO6 Powering the Industrial Revolution中的句子简化题原句“Only the last of these was suited at all to the continuous operating of machines, and although waterpower abounded in Lancashire and Scotland and ran grain mills as well as textile mills, it had one great disadvantage: streams flowed where nature intended them to, and water-driven factories had to be located on their banks whether or not the location was desirable for other reasons.”很长，但是考生可以抓住这句话的主要逻辑来解题。句子的主干是：Only the last was suited to …, and it had disadvantage.这句话的主要逻辑是并列，考生要把握这个重点，从而明确正选中必包含这句话中并列的两层含义，就可以高效解题。
2.句子插入题解题中使用逻辑是因为它考察句子间关系，含有明确因果、转折以及递进等逻辑关系的句子，在位置上的关系很容易判断，比如TPO4 Cave Art in Europe中的句子插入题待插入句是“Therefore, if the paintings were connected with hunting, some other explanation is needed.”通过信号词Therefore可以明确这句话属于结果句，这句话中说明的“如果…那么…”这种论断一定是被前面说明的某些原因支持的，所以由此出发可以确定前面句子的大致特点。
对逻辑间接考察的题型有多种。词汇题、推断题等在解题中都可能用到逻辑。
1.词汇题解题中用到逻辑是因为某些词汇的关系可以通过逻辑来判断，从而找到词汇猜测的依据。比如TPO4 Cave Art in Europe中词汇题原句“We might expect that early artistic efforts would be crude, but the cave paintings of Spain and southern France show a marked degree of skill.”,考察词是marked，考生在解题时，根据整句话的整体意思来看：这句话的前后有明显转折，前半句“我们以为早期艺术粗糙”，后半句“但是显示出了…的程度”,由此猜测词汇和“粗糙”是矛盾的概念，结合选项中词汇的褒贬可以快速解题。
2.推断题需要考生在原文基础上合理推测，这些思维过程需要逻辑的辅助。很多情况下，考生可以利用对比(包含转折逻辑)等进行推断。比如Petroleum Resources中的推断题需要考生推测关于gushers正确的信息，相关句是“Although this rise of oil is almost always carefully controlled today, spouts of oil, or gushers, were common in the past.”，由此可以看到in the past和today两个时间概念的对比(从转折逻辑得出)，本句话表明in the past的gushers是common的，所以可以推测today应该相反，也就是不常见的，由此确定答案。
以上就是前程百利小编为大家带来的托福阅读考点之逻辑的相关内容，结合逻辑和题目为大家带来的分析，以上四种题型都和逻辑关系很大，希望引起考生重视。预祝大家托福考试取得好成绩!
