?我的领悟
1．句1、2、3中的it作形式主语，真正的主语是后面的________________。
2．句4、5中的it代替的真正的主语是________________。
3．句6、7中的it代替的真正主语是由____________或____________引导的从句。
当主语部分相对于谓语部分而言太长时，常把主语部分移到句尾，在主语的位置放上it。it 没有具体的意义，仅用于使句子显得平稳，不头重脚轻。it 作形式主语时常代替三种语法结构： 不定式(短语)、v. ing(短语)和从句。
一、it代替不定式(短语)作形式主语
1．It＋be＋名词/名词词组＋to do sth.，这类名词有a habit、a pleasure、a fact 等。
◆It is not a good habit to stay up too late.
睡得太迟不是个好习惯。
2．It＋be＋形容词＋(for sb.)＋to do sth., 这类形容词用来描述不定式行为本身的性质有necessary、wrong、right、important、difficult、easy等。
◆It is necessary for you to be fully aware of your own shortcomings.
充分认识自己的缺点是很必要的。
3．It＋be＋形容词＋of sb.＋ to do sth.，这类形容词用来描述不定式行为者的性格、品行等时，不定式前常可加一个由of引起的短语。这类句型所涉及的常用形容词有foolish、kind、good、polite、selfish等。
◆It was foolish of you to behave like that.
你那种表现真是太蠢了。
4．It＋takes＋sb.＋时间或金钱＋to do sth.，这是一个表示某人花了多少时间或金钱做某事的句型。其中it是形式主语，代替后面的不定式，句中的sb.也可省略。
◆It took thousands of people many years to build the Great Wall.
成千上万的人花了很多年才建成了长城。
二、it代替v. ing(短语)作形式主语
It＋be＋名词/名词词组＋ doing sth.，这类名词有(no) good、(no) use、(no) time、a waste of time、fun等。
◆The doctor told us that it is no good eating too much meat.
医生告诉我们吃太多的肉没有好处。
it作形式主语代替v. ing(短语)时，往往限于以下句型中：It is no good/no use/fun/a waste of time...中，如不是上述句型，在将v. ing(短语)移到句尾用it作形式主语时，v. ing(短语)要改为不定式。

三、it代替从句作形式主语
用it 作形式主语的结构主要用于下列句型：

◆It is common knowledge that the full moon brings fair weather.
皓月兆天晴，这是常识。
