当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾。 此时it仍只起先行引导作用，本身无词义。

2. 动词 + it + when/if 从句，常见于appreciate, enjy, like, prefer, lve, dislike等动词之后。
Translate如果您能帮助我们，我们会很感激。 We really appreciate it if yu culd d us a favur.我不喜欢有人嘴里含着食物说话。 I hate it when peple speak with their muth full.
3. 动词 + it + 介词 + that从句，常见于 we it t sb. that… (把……归功于)， take it fr granted that… (认为……理所当然)，put it t sb. that… (向某人挑明) 等结构中。
Translate多亏有你，我们现在才仍然活着。 We we it t yu that we are still alive.我还想当然地以为他总能随叫随到呢。 I just tk it fr granted that he’d always be arund.
