在英语中什么情况下动词用原形?

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 was wrong. 我的确认为他错了。

  9.不定式作介词but和except的宾语,当其前有实意动词do时,后面的动词不定式要省略to。如:

  Jack had nothing to do but/except watch TV. 杰克除了看电视外无事可做。

  10.在一些固定的句型中,如had better(最好),would rather (宁愿),would rather…that…(宁愿…而不)等后面的动词要用原形。如:

  You had better have a good rest. 你最好好好休息一下。

  He would rather go to work by bike. 他宁愿骑自行车去上班。

  As a revolutionary,he would rather die with his head high than live with his knees bent. 作为革命者,他宁愿昂首而死,而不愿屈膝求生。

英语单词中动词什么情况下用原型?

.情态动词后面加原型:can,may,should.......

2.助动词后面也是:do,did,does

3.to后面是要加动词原型的,不过一些固定搭配也有to后面加动词ing形式的,比如说,make a contribution to doing; look forward to doing..........不能光看to哦,O(∩_∩)O~希望对你有帮助哈!

英语有时 逗号后面直接加动词原型 这是什么情况?哪些情况下可以直接加?

两个问题都属于不定式省略to的情况,

即make, crowd其实完整应该是to make, to crowd

一般不定式充当并列成分的时候,后面的不定式符号to可省,如:

His job is to clean the house, wash the dishes and cook food.

rather than一般其后都跟不带to的不定式。
