⒈不定式作宾语①以下动词后，只能跟不定式作宾语。
如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long,manage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接th at引导的从句。
如：I decided to ask for my money back.I decided that I would ask for my money back.When our visit to the farm was over,we expected to startback on foot.When our visit to the farm was over, we expected that wewould startback on foot.②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。
如：We think it quite important for us to learn a foreignlanguage well.He feels it his duty to help the poor.③介词but,except,besides+to do(do)在这种句型中，如介词前有动词do，后面应接不带to的不定式；如无do，则接to不定式，即带do不带to，带to不带do。
如：The enemy soldiers had no choice but to give in.On Sunday afternoon I had nothing to do but watch TV.⒉动名词作宾语①以下动词后，只能接动名词作宾语，如：admit,appreciate,consider,delay,enjoy,finish,keep,imagine,mind,miss,practise,resist,risk,save,suggest,don't mind,giveup,insist,on, put off等。
如：I suggest spending our summer vacation in a seaside town.You must give up smoking, for it does too much harm toyour health.②动名词作介词的宾语I should go to attend the birthday celebration instead of staying athome.What about inviting Li Jun to make a speech?动名词前的介词有时可以省略，如：have difficulty(in)doing,have notrouble(in)doing,lose no time(in)doing,prevent/stop…(from)doing,there is no use(in)doing等。
⒊部分动词后面，既可接动词不定式，也可接动名词作宾语，意义不变。
如：begin,continue,start,hat e,like,love,need,require,want等。
在need,require,want后接-ing形式，表示被动意义，也可接不定式，但要用被动形式，如：Your handwr iting needs improving(tobe improved).hate, love, like接不定式表示特定的未来事件，接动名词表示目前正在进行的活动或一般的行为。
在下列情况下，一般要用不定式：①hate, like, love前有would(should)时，如：I'd like to have a cup of coffee.②当谓语动词begin,continue,start等是进行式时，如：The students are starting to work on the difficult maths problem.③begin, continue, start与know, understand等状态动词连用时，如：I soon began to understand whatwas happening.⒋advise, allow, encourage, forbid, permit等动词后接动名词作宾语，或带不定式作宾语补足语。
如：Our teachers don't permit our swimming in the lake.Our teachers don't permit us to swim in the lake.⒌部分动词后接不定式或动名词时，意义差别较大，应根据句子语境选择使用。
①forget, remember, regret后接不定式，表示现在或未来的动作，接动名词表示动作已经发生。
如：Don't forget fo post the letter for me.Have you forgotten meeting her in Beijing Airport?Remember to close the windows before you leave.I remember writing him a letter a year ago.We regret to tell you that all of you are not invited toattend the meeting.They regretted ordering these books from abroad.②mean to do打算做某事doing意味着……I meant to catch up with the early bus.This means wasting a lot of money.③try to do设法尽力做某事doing试着做某事You should try to overcome your shortcomings.Try working out the physics problem in another way.④stop to do停下一件事去做另一件事（不定式作目的状语）doing停止做某事On the way to the airport,I stopped to buy a paper.You'd better stop arguing and do as you are told.⑤can't help doing禁不住……to do不能帮助干……They couldn't help jumping up at the news.Sorry I have lots of work to do.So I can't help to make up the room for you.⑥go on to do做不同的事或不同内容的事doing继续不停地做某事，指同一动作的继续He went on to talk about world situation.他接着又谈了世界形势。
