此種以it作虛主詞的用法在英文中很常見。習慣上,英文句子的其他部分通常比主詞長,然而,如果主詞太長,往往會以it當虛主詞,而把真正的主詞往後移,以避免「頭重腳輕」的狀況。it作虛主詞時,後方的真主詞可以是不定詞、動名詞或名詞子句,這裡所介紹的是that所引導的名詞子句。請注意that子句當主詞時,不可以省略that。
另外,此句型多用來「表達事實」或「發表意見」。像是clear、likely、sad、 important、possible、strange、interesting、 probable、true、certain、surprising等。
It is clear that the young man is lying.
It is likely that Andy will come to our place.
It is interesting that some people look like their pets.
除了that所引導的名詞子句,whether和how引導的子句也可以用於以it為虛主詞的句型中
It is uncertain whether the vacancy will be filled soon.
It is amazing how Anne can collect so many stamps.
