(2)-Will you go with me-Well ,I 'd like to.(3)-Will you go home tomorrow -No.I 'm going to a lecture,or at least I am planning to.2.不定式作宾语补足语时,省略to后的动词部分,即用to代替整个不定式.例如:(1)The boy wanted to ride his bicycle in the street but his mother told him not to.(2)You'd better finish the job on time if he ordered you to.3.在一些情态动词或助动词ought to \have to \used to \be able to 后.例如:(1)-Must I go now-No.You don 't have to.(2)-Are you planning to see your grandfather-No.But I ought to.二,省略动词不定式符号to的情况1.动词不定式作感官动词feel \see \notice \watch \find \hear\listen to \observe和使役动词have \make \let等的宾语补足语时,动词不定式符号to省略.如果这些动词用于被动语态,其后的动词不定式符号to不能省略(但let除外).例如: (1)We often hear him sing the song at home .(=He is often heard to sing the song at home.)(2)The y knew her verywell.They had seen her grow up from childhood.(=They knew her very well.She was seen to grow up from childhood.)注意:Mother got Tom to buy a pack of sugar.2.两个或两个以上的动词不定式由连词and \or \than \but连接时,从第二个不定式起,往往省略不定式符号to.但如果强调对比之意时不省略.例如:(1)She 'd like to take off her coat and have a break.(2)The students are taught to read,write and do many other things.(3)I t 's more difficult to do than to say .(强调语意前后对比)(4)The teacher came not to punish you but to help you.(强调语意前后对比)(5)I wondered whether to study or to work.(强调语意前后对比) 3.不定式作表语,用来解释主语或主语从句中do的精确含义时,往往可以省略动词不定式符号to.例如:(1)The first things he did was go up to her trainer and thank her for all her help during her training.(2)What we want to do now is lie down and rest.(3)What a dictionary does is help the students to find out the meaning and the usage of new words .4.在why或why not引起的表示建议或责问的省略问句中.例如: (1)Why get so excited(2)Why quarrel with your mother(3)Why not join us,Tom5.在一些类似情态动词词组had better \would rather \had best \rather than \can't but \can't help but等之后.例如:(1)In China it is important to invest in education rather than increase personal wages.

英语动词不定式的省略的知识点
英语在我们的生活中是很重要的，今天小编就给大家分享一下英语的知识大全，大家有兴趣可以多多看看哦
英语知识
1、动词不定式的省略为了避免重复，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. 2、due to/be due to be due(to)有“应付给，应到的，预期的”之意，多用作表语，to不定式符号;而due to表示“由于，起因于”时，to是介词，相当于because of。
如： The train is due to arrive at 12.火车应于12点到。
When is the ship due?船预定何时到?。
