一、不定式作賓語
1.在以下動詞后,只能跟不定式作賓語。如:agree,ask,aim,arrange,choose,decide,demand,expect,fail,help,hope,lean,long,manage,offer,plan,prepare,pretend,promise,refuse,wish等,這些詞大部分可接that引導的從句。如:
(1)I decided to ask for my money back.
(2)I decided that I would ask for my money back.
(3)When our visit to the farm was over,we expected to start back on foot.
(4)When our visit to the farm was over,we expected that we would start back on foot.
2.當復合賓語中的賓語是不定式時,先用形式賓語it代替不定式,把不定式置于補語之后,即主語+動詞+it+補語+to do句式。如:
(1)We think it quite important for us to learn a foreign language well.
(2)He feels it his duty to help the poor.
3.介詞but,except,besides+to do(do)。在這種句型中,如介詞前有動詞do,后面應接不帶to的不定式;如無do,則接to不定式,即帶do不帶to,帶to不帶do。如:
(1)The enemy soldiers had no choice but to give in.
(2)On Sunday afternoon I had nothing to do but watch TV.
二、動名詞作賓語
1.在以下動詞后,只能接動名詞作賓語,如:admit,appreciate,consider,delay,enjoy,finish,keep,imagine,mind,miss,practise,resist,risk,save,suggest,don’t mind,give up,insist,on,put off等。如:
(1)I suggest spending our summer vacation in a seaside town.
(2)You must give up smoking,for it does too much harm to your health.
2.動名詞作介詞的賓語。如:
(1)I should go to attend the birthday celebration instead of staying at home.
(2)What about inviting Li Jun to make a speech?
動名詞前的介詞有時可以省略,如:have difficulty (in) doing,have no trouble (in) doing,lose no time (in) doing,prevent/stop...(from)doing,there is no use (in) doing等。
3.部分動詞后面,既可接動詞不定式,也可接動名詞作賓語,意義不變。如:begin,continue,start,hate,like,love,need,require,want等。
在need,require,want后接-ing形式,表示被動意義,也可接不定式,但要用被動形式,如:Your handwriting needs improving (to be improved).hate,love,like接不定式表示特定的未來事件,接動名詞表示目前正在進行的活動或一般的行為。
在下列情況下,一般要用不定式:
(1)hate,like,love前有would(should)時,如:I’d like to have a cup of coffee.
(2)當謂語動詞begin,continue,start等是進行式時,如:The students are starting to work on the difficult maths problem.
(3)begin,continue,start與know,understand等狀態動詞連用時,如:I soon began to understand what was happening.
4.advise,allow,encourage,forbid,permit等動詞后接動名詞作賓語,或帶不定式作賓語補足語。如:
(1)Our teachers don’t permit our swimming in the lake.
(2)Our teachers don’t permit us to swim in the lake.
5.部分動詞后接不定式或動名詞時,意義差別較大,應根據句子語境選擇使用。
5.1 forget,remember,regret后接不定式,表示現在或未來的動作,接動名詞表示動作已經發生。如:
(1)Don’t forget to post the letter for me.
(2)Have you forgotten meeting her in Beijing Airport?
(3)Remember to close the windows before you leave.
(4)I remember writing him a letter a year ago.
(5)We regret to tell you that all of you are not invited toattend the meeting.
