形式主語中名詞性從句作真正主語的情況

與漢語習慣不同，英語習慣將較重要的信息放在句子後半段，爲避免頭重腳輕，就產生了一個邏輯主語it，同時也就產生了一種新的的語法現象——形式主語。今天小編整理了一些由名詞性從句作真正主語的情況，一起來看一下吧。

It +動詞+從句

seem,appear,happen,look,matter,make,strike,occur

It appeared that he had a happy childhood.

看來他有一段幸福的童年。

It made us very happy that she was saved.

她能化險爲夷令我們大家很高興。

It is +形容詞+從句

true,strange,necessary,important,certain,wonderful,possible,likely,probable

It is certain that free medical care will be given to most people in our city. 我們城市的多數人將享受免費醫療，這是一定的。

It is obvious that he has been treated.

很明顯他已經被款待了。

It is +名詞+從句

fact,surprise,pity,honor,common knowledge

It is common knowledge that the moon cannot give out light. 月亮不會發光，這是常識。

It is a surprise that you gave such an answer to the question. 你對這個問題作了這樣的回答，令人吃驚。

It+be+分詞+從句

said,reported,believed,known,decided,thought,expected,announced

It is said that Jack has been to Europe.

據說Jack去過歐洲。

It was reported that a new park will be built.

據報道將要建造一個新的公園。

需要注意的是，作爲形式主語的it並無實際意義，只是爲了滿足語法上的需要，避免句子頭重腳輕，它代替的是句子的邏輯主語，而真正主語由從句或不定式充當。形式主語一直都是高頻考點，還請大家多多練習。
