IT做形式主语
用法一：it作逻辑主语综述形式主语it 作为形式主语的it并无实际语义，只是为满足语法上的需要，避免句子头重脚轻，它代替的是句子的逻辑主语，概括起来会有如下情况：不定式作逻辑主语如：It is very kind of you to give me a hand in time.It is my pleasure to address the meeting.It was pretty hard for him to bring up the child on his own.从句作逻辑主语如：It so happened that the tickets were sold out.It is extremely obvious that she has been lying about her identity.It suddenly occurred to me that the message must have been hidden between the layers of the briefcase.动名词短语作逻辑主语这类句子远不如前面两种出现率高，主要在（no, good, waste, useless, no use, dangerous）等词语的后面用如：It is no use reasoning with him.It is no good reading in dim light.作形式主语的代词只能用it ，不能用that，this等词。
例如: 1）It is easier to lose friends than to make friends.交朋友难而失去朋友比较容易。
2）It is important for modern young people to master at least two foreign languages.掌握至少两门外语对于当代年轻人来说是很重要的。
