It作形式主語(yǔ)的用法

當(dāng)代英語(yǔ)中，通常用it 做形式主語(yǔ)，將不定式和動(dòng)名詞置于謂語(yǔ)后面，特別是主語(yǔ)較長(zhǎng)時(shí)，或在一些習(xí)慣用法中。

1) 謂語(yǔ)是系表結(jié)構(gòu)（be + 形容詞 / 名詞）時(shí)，常將不定式后置，構(gòu)成句型 “it + be + 表語(yǔ)（形容詞 / 名詞）+ 不定式”。

It is my duty to care for that patient.

照料那位病人是我的職責(zé)。（做主語(yǔ)的不定式to care for that patient 后置，it 為形式主語(yǔ)）

2) 當(dāng)謂語(yǔ)是 take，make，pay，cost ，require， feel，need 等動(dòng)詞時(shí)，或者是與情緒有關(guān)的動(dòng)詞 delight，amuse，excite，annoy，irritate 等時(shí)，習(xí)慣上常用 it 做形式主語(yǔ)，并將不定式后置。

It takes only ten minutes to get there.
到那兒只需十分鐘。

3) 同不定式一樣，動(dòng)名詞也可用于“it + be + 表語(yǔ) + 動(dòng)名詞”句型中。

It is a waste of time to argue with him
It is a waste of time arguing with him.
和他爭(zhēng)辯是浪費(fèi)時(shí)間。

4) 但表語(yǔ)是（of）no use，not any use，not the slightest use， no good， not much good，fun等時(shí)，常用動(dòng)名詞（不用不定式）做主語(yǔ)并后置，用 it 做形式主語(yǔ)。

例如 It's no use crying over spilt milk.覆水難收。

Who cares about that after they lose their child?
