考研英语It的用法
考研英语It的用法语法是英语学习的基础，英语冲刺复习，有哪些重点语法需要大家关注呢?It分为两种情况，一种是指代性it,另一种则为非指代性it。
在此为大家介绍it的几种用法。
指代性it一般是指人称代词it，it作人称代词时可指代事物、动物、婴儿、未知的人或一件事。
例句1：It’s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. 这句话中第二个it就是指代前面的theory。
这是一个许多经济学家赞同的理论，但是在实际中，它往往会使得铁路处于一个决定哪些公司会兴旺，哪些公司会衰败的地位中。

非指代性it是相对于作人称代词的it 而言的。
他们往往没有具体意义上的主语，它用于表示气候、温度、时间、地点、距离等。
非指代性it常作seem, appear, look, happen, occur, follow等动词的主语，构成特定的句型。
例句：From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years.这句中it没有实际意义，为非指代性用法，that引导表语从句。
