第一章英文文法最基本规则
1、两个动词是不能连在一起的
错误I am love you.I love watch television.
正确的是I love you.或者I am in love with you.
2、如一定要同时用两个动词,后面的前者必须加to或者将后者加ing
I hate to eat fish.I hate eating fish.
3、主语如果是第三人称,现在式及单数,动词必须加s。
Jack loves playing the violin.
4、绝大多数的否定句子,不能直接加not
错误:I not love you.
用助动词来完成否定句子
I do not love you.I did not see that movie.He does not like playing violin.
助动词包括do,can,will,would,shall,may,must等
5、在不定动词to的后面,必须用原形动词
动词分原形动词,过去式,单数,复数
am,are,is,was,were等翻译成中文都是是,这些动词的来源都是be,因此又称为verb to be格式
I want to be a teacher.
6、在否定语句,疑问句等,助动词后跟原形动词
但助动词have后面不用原形动词,即现在完成时
I have slept all day.
In this sentence ,slept is a past participle.The above example is present perfect tense.
7.
Interrogative sentence must have an auxiliary verb.?(疑问句必须有一个助动词)
example:Error How many books you wrote?
Right:How many books did you write
But if a sentence have the 'verb to be ' struct, it does not need an auxiliary verb in interrogative sentence.
Example:Are you a teacher?
8.
Special verb change with subject.特殊动词随主语而改变
Verb to be is one of these.
Verb to have
(He,She,It)has,other is have,example:I have,They have
The all of past tense is had.
