动词后接不定式与动名词的问题
经常会有学生问我:某某动词后,究竟是接不定式还是动名词呢?有没有什么规律呢?
某某动词后究竟是接不定式还是动名词,如果单纯从语法或用法的角度进行分析归纳,我觉得会把简单的问题复杂化,很多文章中总结出不是规律的规律多少多少条。我的建议是:后接不定式还是动名词,很大程度上是英语使用习惯。坦率地说,我也不一定个个分得清。好在这些动词都是些常用的词汇,多花点时间记住就可以了。
一、动词加不定式
我们先来讲一下动词加不定式的问题。后接的不定式,一般表示一件具体的事或者是还没有发生的事。它可以分为三种情况。
1、动词+不定式
后接不定式的动词有:
afford负担得起  aim针对                agree同意
appear 显得    arrange 安排            ask
attempt企图    bear承受                begin开始
beg请求        bother 扰乱              care关心,喜欢
cease停止      choose选择              claim要求
contrive 设法  consent 同意          decide决定
decline推却    demand要求            design设计,预定
desire愿望      determine决定          destine注定
dread害怕      enable能够              endeavor努力
expect期望      fail不能                  forget忘记
happen碰巧      hate 憎恨                hesitate犹豫
hope希望        incline 倾向              intend想要
learn学习      like喜欢                    loathe 不喜欢
long渴望        love                      manage设法
mean意欲        need需要                  neglect忽视
offer提供      omit忽略                    plan计划
prefer喜欢      prepare 准备            pretend假装
profess表明    promise承诺            propose提议
refuse拒绝      regret 抱歉              scorn忽视
seek 寻觅        start开始                swear宣誓
try试图        undertake 承接          volunteer志愿
vow起誓        want想要                wish希望
The driver failed to see the other car in time.
司机没能及时看见另一辆车。
I happen to know the answer to your question.
我碰巧知道你那道问题的答案。
2、动词+宾语+不定式
部分动词后面可以带一个宾语,再接不定式。从语法的角度说,不定式是宾语的补足语。常见的动词有:ask, beg, choose, expect , hate, help intend like, love, need prefer, prepare, promise, want, wish 等等。例如:
I like you to keep everything tidy. 
我喜欢你年使每件东西都保持整洁。
Please remind me not to be late for the meeting.
请提醒我不要开会迟到了。[注意:不定式的否定形式]

They forbade her to leave the country.
I consider him to be the best candidate.
3 动词+疑问词+ to
部分动词后的不定式前面,还可以加上特殊疑问词,如how, where, when 等,它实际上是不定式的状语。这些动词有:decide, know, consider forget, learn, remember, show, understand, see, wonder, hear, find out, explain, tell 等。例如:
Please show us how to do that.
请演示给我们如何去做。

二、 动词后接动句词
我们再来看一下动词后接动句词的问题。后接的动名词,从整体上表示某件事。例如:I'd like to go to swim this afternoon. (今天下午我去游泳。) 这里的游泳是指一件()具体的事。而 I like swimming in a lake. (我喜欢在湖里游泳。) 这里的游泳就是指整体上的游泳这件事,而不是一件()具体的游泳。动名词或者表示已经做过的事。不定式与动名词做宾语的区别,请参看本站相关文章。
常用的后接动名词的动词有:
acknowledge 承认,自认    admit承认              advocate提倡,主张
appreciate 感激,欣赏          avoid避免              bear忍受
can’t help不禁                can’t stand受不了      consider考虑
cease停止                      commence开始            complete完成
confess坦白                    contemplate细想        defer拖延

hate 讨厌                        keep保持                loathe 不喜欢,讨厌
mention 说到,讲到        mind介意                miss错过

enable的名词形式resent 怨恨                      resist抵抗,阻止        resume恢复
risk冒险                        suggest建议                save营救,储蓄
stand 坚持,忍受        tolerate忍受;宽容      understand明白,理解
还有部分词组也要接动名词。例如:
admit to, preferto, be used to, lead to, devote oneself to, object to, stick to, 
be busy,  look forward to,  no good, no use, It's worth, as well as,
can't help, It's no use /good be tired of , be fond of, be capable of, be afraid of

1、两种在意义上差别不大。例如:
