Paul doesnt have to be made to learn. 3) 动词help help sb do help sb to do help to do,2、有些动词后只跟不定式： want，wish，hope，manage，promise，refuse，pretend，plan， offer，decide，agree，expect allow sb to do, cause sb to do , permit sb to do, enable sb to do ，force sb to do，be more likely to do ， love to do， warn sb to do、be ambitious to do、 start to do 3、有时候to后面要接-ing形式： accustom (oneself) to; be accustomed to; face up to; in addition to; look forward to; object to; be reduced to; resign oneself to; be resigned to; resort to; sink to; be used to; be alternative to; be close/closeness to; be dedication/dedicated to; be opposition/opposed to; be similarity/similar to. 4、need/want 后的-ing具有被动意思。(want不太常用) He needs (a lot of) encouraging.,5、不定式的独立主格结构 不定式具有它自己的独立主语时，二者即构成不定式独立结构，常用作伴随的状语和主语。 eg. I to bear this is some burden. 6、“for + 名词（代词）+不定式” 结构 for的复合结构，它在句中可用作主语、表语、宾语、定语、状语等。 eg. For a child to do that job is just inconceivable. 7、“疑问词+不定式”结构 who, what , which , where , how等构成的短语，在句中可用作主语、宾语、表语等。,运用动名词时的注意点： 1、有些词后只能接动名词 admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; cant help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand. 2、一些动词接-ing形式的常用说法： its no good; its no/little/hardly any/ use; its not/hardly/scarcely use; its worthwhile; spend money/time; theres no; theres no point in; theres nothing worse than; whats the use/point.,3、有些词后加不定式和动名词均可；但remember, forget, try, stop, go on, cease, mean后面用不定式和-ing形式，意义截然不同。 I remembered to post the letters.
