1.与助动词或情态动词do,does,did,shall,will,should,would,may,might,have to,must,need,ought to等一起构成谓语的动词时,要用原形.
如: Do you like English?你喜欢英语吗?
May I use your telephone?我可以用你的电话吗? We must study hard and make progress every day.我们必须好好学习,天天向上. Shall we tell her to wait?我们要不要告诉她等一下?
2.祈使句的谓语动词,要用原形.
如: Close the door behind you,please.请随手关上门.
Don't make a noise.别吵闹.
Let's live in peace and friendship.让我们生活在和平和友谊之中.
3.感觉动词look at,see,watch,notice,listen to,hear,feel等的宾语与其补足语构成逻辑上的主谓关系,表示动作的最后结果或全过程时,作宾语补足语的动词要用原形.但改成被动语态要带to.
如: I saw the train come into the station.我看见火车进站了.
I heard a letter drop.(A letter was heard to drop.) 我听到信掉了下去.
4.使役动词let,have,make后的宾语与作宾语补足语的动词构成逻辑上的主谓关系时,这个动词要用原形.但改成被动语态要带to;let后的动词可不带to,如: He let Jack lead the way.他让杰克在前面带路.
Have him send the letter.叫他把信送去.
His jokes made us all laugh.他的笑话使我们都大笑起来. Everyone must be made to know nobody should break the law. 应使每个人都知道,谁也不得违法.
5.两个以上的并列不定式用and或or连接起来,第二个不定式常省去to.
如: Let's go and play football.我们去踢球. It is fun to jump into pool or go swimming in a river in summer. 在夏天跳进游泳池或江河里去游泳是很有趣的.
6.在why not…和why…句型中,not和why后直接跟动词原形,构成反问,表示“建议、劝告、责备或提醒”等.如: Why not use my bicycle?为什么不用我的自行车呢? Why waste so much money?为什么要浪费那么多钱呢?
7.动词help后是复合宾语,其宾语补足语由动词充当时,这个动词前带to或不带to都可,但在被动语态中必须带to.
如: She helped me (to) clean the room. (I was helped to clean the room byher.)他帮我打扫房间.
8.do,dose,did与动词原形连用,以加强语气,不但可以用在祈使句中,而且也可用在一般现在时和一般过去时的肯定陈述句中.
如: Do be careful!一定要当心! She does look nice today.她今天看起来的确漂亮. I did think be wa
