虛主詞 - It
Dummy Subjects - It
「虛主詞」顧名思義,就是「虛位」的主詞,佔在主語的位置上,但徒具形式而不具實義,主要目的是引導句子後段的重點。
影片中講者說 It is a good idea to try to understand the fear. 「我們該去了解這種恐懼。」其中,to try to understand the fear 為此句真正的主詞。若將這句話改寫成 To try to understand the fear is a good idea. 文法上無誤,只是太長的主詞會顯得此句頭重腳輕。我們來看看更多此句型的例子:

It's nice to live in such a beautiful house.
