那些动词不定式前可以省略to
如题
如题
动词不定式省略to的情况:
(1)不定式在感观动词(see,notice,look at,listen to,hear,watch,feel,observe)、使役动词(let,make,have)后作宾语补足语时,通常省去to.如:
I have my students come early.
(2)不定式在help后作宾补时,可带to,也可省略to.如:
I helped him(to)find his lost watch.
注意:以上两种情况变成被动语态时要加上to.如:
She was seen to go into the classroom.
(3)如果两个或多个不定式并列使用时,常在第一个不定式前面加to,后面一般都省略.如:
To try and fail is better than not to try at all.
6.“疑问词+不定式”组成的不定式短语在句中可以作主语、宾语和表语.如:
She told me when to start.
