to后面动词的省略用法的?
如：used to放在句末时,假如后面是be动词的话,be动词不能省去.如果是do的话能省去吗?等等动词.
像此种用法,我记不清楚了,麻烦高手帮忙归纳下to后面动词的省略情况或者说to后面的哪些是能省去的?问题补充：
上面的表达不知道大家看懂没有我的意思是,就好像ought to 后面再接动词的话那些可以省去哪些不能省去
好像be和have放在to后面是不能省去,我需要to后面动词不能省去的常见情况
答：这个问题实际上是不定式的省略,指为避免重复,在有上文的情况下,只保留不定式符号to,而省略不定式后面的部分.
动词不定式的省略及其符号to的保留
1.Would you like to go to the cinema with us?
Yes,______.What time are we going to meet?
A.I would B.I would like C.I like to D.I'd like to (浙江省)
2.Would you like to go for a picnic with us?
______.What time are we going to meet?
A.No,I can't B.Yes,I'm glad C.Yes,I'd love to D.I'd like (大连市)
Keys：1.D 2.C
［简析］在口语中,动词不定式中的动词或短语动词在上下文中重复出现时,第二个动词不定式可以省略,但是to不可省略.这种用法常见于＂be glad to＂,＂would like (love) to＂,＂have to＂等结构中.
