不定式分句可以在句子中作主語(yǔ)和主語(yǔ)補(bǔ)語(yǔ)、賓語(yǔ)和賓語(yǔ)補(bǔ)語(yǔ)、狀語(yǔ)等。具體而言:
1. 作主語(yǔ)和主語(yǔ)補(bǔ)語(yǔ):
To finish the work is very easy.
完成這項(xiàng)工作很容易。(=It is very easy to finish the work.)
Last year, the wisest policy was not to interfere any more.去年最明智的政策就是不再干預(yù)。
2. 作賓語(yǔ)和賓語(yǔ)補(bǔ)語(yǔ):
I learned to speak English when I was young. 我小時(shí)候就學(xué)習(xí)說英語(yǔ)了。

3. 作狀語(yǔ):
(1)表目的:
She opened the window to get more fresh air. 她打開窗戶呼吸更多新鮮空氣。
(2)表結(jié)果:
He hurried to the station only to be told that the train had left.
他匆忙趕到車站,結(jié)果火車已經(jīng)走了。
(3)表原因:
I was really lucky to pass the final exam. 能通過考試,我真的很幸運(yùn)。
I am sorry to hear that news. 聽到這則消息,我感到很抱歉。
由上可知,不定式分句作為一種分句結(jié)構(gòu),主要有以上三種句法功能。當(dāng)然,它還可以在名詞詞組中作修飾語(yǔ),在形容詞詞組中作補(bǔ)足成分,這里就不一一贅述。
