60 不定式作主語(yǔ):It + … + to do sth. Track 060
(1)It + … + to do sth.
不定式作主語(yǔ),常見(jiàn)的是用it作形式主語(yǔ),放在句首,將真正的主語(yǔ)——動(dòng)詞不定式(短語(yǔ))放在句子后面。
a. It is easier to spend money than to make money.
b. It takes time to study English well.
注意:此處形式主語(yǔ)it不能用this或that來(lái)替換。
This(A) is impossible for(B) people to stare directly(C) at the sun. 人們不可能直視太陽(yáng)。
答案:A。This 改為It。
(2)不定式結(jié)構(gòu)也可直接置于句首作主語(yǔ),此時(shí)謂語(yǔ)動(dòng)詞要用單數(shù)形式
