很多考生在备考托福的时候都会去看一些机经，因为机经对考试还是很有帮助的。那么，什么是托福机经以及它有什么用处呢？接下来，小编就和大家聊一聊这个话题。
首先，要弄清楚几个概念。
1.什么是托福机经？
历次托福考试的内容。是由参加考试的考生一点一滴回忆起来的，并非完全的真题还原。
2.什么是托福机经题库？
每次托福考试都有可能考到以前考过的内容，也可能出以前没有考过的新题。托福机经题库就是题库和托福考试有关的两件事情：
1）什么时候出新题，什么出旧题，什么时候出拼盘。
2）机经范围。也就是如果出旧题或者拼盘，会从哪几套旧题中抽取
3.托福机经多长时间出一次?
网上各种方法题库的机经一般以一个月为单位，在月末或者月初的时候公布。
4.什么是拼盘？
从两套题中各选取阅读、听力、口语或写作部分，拼凑成一套完整的题目就是拼盘，有时候也会出现旧题和新题的拼盘。
然后，再来看一看小编整理的一些机经吧。
