动词不定式是我们在英语试卷中见到的普通的不能再普通的句型了，虽然普通，但是却十分重要，下面是我们全国一对一家教高级英语教师为你提供的讲解，告诉你有些动词不定式是可以省略的。
为了避免重复，我们常常把作宾语、宾补和谓语动词的一部分的不定式省略，只保留动词不定式的符号to。现将常见省略不定式的几种情况通过实例加以简析，供大家参考：
(1)—How about coming to my house?
—I’d love to if it doesn’t give you so much trouble.
在hope, like, love, promise, want, wish等词后作宾语的不定式常省略。再如：
You may go if you want to.
She can get a job if she hopes to.
—How about going hunting with me tomorrow?
—I’d like to, but I have no time.
(2)Don’t close the window until I ask you to.
在allow, ask, tell 等词后作宾语补足语的不定式常省略。再如：
Don’t touch the light unless your mother allows you to.
Don’t plant potatoes until the peasant tells you to.
(3)He didn’t want to hand in his composition, but he had to.
在be able to, be going to, have to, need to, enough to, used to等后的不定式需省略。再如：
I don’t sing much, now, but I used to a lot.
If you don’t want to say anything at the meeting, you don’t need to.
She didn’t go out last night, because she was afraid to.
在afraid, glad, happy, pleased, sorry等词后作状语的不定式常省略。再如：—Will you go with me to see the film tonight?
—I’ll be glad to.
