大家好，我是小夏，我來為大家解答以上問題。形式主語的例句，形式主語很多人還不知道，現(xiàn)在讓我們一起來看看吧！

1、形式主語it

2、作為形式主語的it并無實際語義，只是為滿足語法上的需要，避免句子頭重腳輕，它代替的是句子的邏輯主語，概括起來會有如下情況：

3、句子的邏輯主語為不定式

4、 如：It is very kind of you to give me a hand in time. It is my pleasure to address the meeting. It was pretty hard for him to bring up the child on his own.

5、句子的邏輯主語為從句

6、 如：It so happened that the tickets were sold out. It is extremely obvious that she has been lying about her identity. It suddenly occurred to me that the message must have been hidden between the layers of the briefcase.

7、句子的邏輯主語為動名詞短語

8、 這類句子遠不如前面兩種出現(xiàn)率高，主要在（no good, waste, useless, no use, dangerous）等詞語的后面用 如：It is no use reasoning with him. It is no good reading in dim light. 作形式主語的代詞只能用it ，不能用that，this等詞。例如: 1) It is easier to lose friends than to make friends. 交朋友難而失去朋友比較容易。 2) It is important for modern young people to master at least two foreign languages. 掌握至少兩門外語對于當代年輕人來說是很重要的。 以上兩句中的it是形式主語，真正的主語是后面的不定式短語。 3) It is considered no good reciting without understanding. 不理解的背誦被認為是沒有好處的。 4) It is no use crying over spilt milk. 覆水難收。 以上兩句中的it是形式主語，真正的主語是V-ing形式。 5) It is a fact that English is being accepted as an international language.英語作為一門國際語言正日益為人們所接受，這是不爭的事實。(NMET,95) 6) It depends on the weather whether we will go. 我們?nèi)ゲ蝗サ每刺鞖庑惺隆?其中的whether 不能換成if,因為if不能引導(dǎo)主語從句。) 以上兩句中真正的主語是名詞性從句。
