一、动词不定式的句法功能
1. 作主语
2)用it作形式主语用不定式(不定式短语作主语时,经常用it做形式主语,把不定式短语放在后边)
(It + be + adj. / n. + to do sth)
3)例外:在下面的结构中,用动名词做真正的主语
It is no good /no use /no help + doing sth.
It is no use arguing about it.
1) 做主语
To see is to believe.(眼见为实)
It is important to learn English.
2. 作宾语
1) v+只跟to do
learn /agree/ask/offer/happen/pretend/
promise/plan/intend/hope/wish/ decide/ refuse/
fail/ manage …
She hopes to find a better job.
I wish to go with you.
