【方法技巧】it作形式宾语用法点击

    it常用于一些固定句式中，作动词(短语)的宾语，没有实际意义，主要有以下三种形式：

①置于like love hate dislike appreciate prefer make后面，并且其后常接if或when引导的宾语从句。

I would appreciate it if you could pay a visit to my house tomorrow.

明日如能光临寒舍，我将万分荣幸。

②当see to depend on/upon insist on answer for count on等动词短语后面接that引导的宾语从句时，通常加上形式宾语it，且see to和insist on可以省去介词，直接跟that从句。

You may depend on it that he’ll join our club.

你可以指望他加入我们的俱乐部。

See(to it )that you always carry your passport.

你得常常带着你的护照。

③动词have(表明，坚持说)，take(认为，猜想)，hide(隐瞒)，publish(公布)，put(表达，写出来)等后面接由that引导的宾语从句时，往往在从句前加形式宾语it。

I take it that you will be leaving Shanghai soon.

我认为你很快要离开上海了。
