三大类,词法、三大从句、特殊句式。英语语法是针对英语语言进行研究后,系统地总结归纳出来的一系列语言规则。英语语法的精髓在于掌握语言的使用。第一:词法:动词(时态和语态,情态动词、虚拟语气)、名词、形容词和副词、数词和介词、连词。第二:三大从句(定于从句、状语从句、名词性从句)。第三:特殊句式(强调、反义疑问句‘省略、强调、there be 存在句)。

所谓助动词 是来帮助动词的 ,所以助动词不能独立存在(不然你帮谁)be动词 是用来连接主语和主语的身份/状态/特征的 属于连缀动词(或者叫系动词)只存在于主系表结构中也就是 当你想表达 某个东西/人 是 什么状态/特征/身份的时候,才会用到系动词(包括be)当你想表达某人做了什么动作时,就要用到一般动词(行为动词,比如吃喝拉撒走跑唱跳等)

be是一个连系动词,它有自己不同的形式 现在时:be 进行时:being 过去时:was/were 过去分词:been 它的后面必须跟形容词或名词作表语,与之构成系表结构,充当句子的谓语。 i am a student主语:i 谓语:am a student(系表结构) being是它的现在进行时态,一般不单独用,而是用于现在进行时的被动语态。(being+动词过去分词) the bike is being repaired.单车正在被修理中。 it is being finished by him这正在被他完成中。 been是它的过去分词,也不一般单独使用,而是用于现在完成时、过去完成时以及需要它的句子。 i have been here for a long time.我已经到这里有一段时间了。 至于你的问题,这与你想表达的意思有关。 你的工作是什么? what do you do what is your job 那么这里选用do和is有什么根据呢? 第一句里面,第二个do是指你做什么,也就是你的工作,就是一个实义动词。按中文说,what you do已经足够了。可是英语里面就不行,必须跟一个助动词,也就是do. 这里就有了一个结论:当句子中有动词时,我们就用助动词do或是does.如果没有动词时,我们就选用is或是are,也就是b“Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were. 在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb). 当主动词时,“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如: 1. The man is a science teacher. 2. Mary's new dresses are colourful. 3. I have been there before. 4. Mother is in the kitchen now. 这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可: 5. Is the man a science teacher 6. Are Mary's new dresses colourful 7. Have I been there before 8. Is mother in the kitchen now 当“be”要在祈使句中出现时,它必须借重助动词“do”或“don't”之助,如: 9. Don't be silly! 10. Do be obedient! 11. Don't be a fool! “Be”有两种缩写法,如下: 12. He's not...../He isn't.... 13. You're not...../You aren't... 但“am + not”的缩写法只有一个: 14. I'm not. 有人用“ain't”, 但这并不是标准英语。 谈过了“be”作主动词的功能,现在看看“be”作助动词时,有些什么用法: 1.“Be + 现在分词”以组成进行式时态(Continuous Tenses),如: 15. Tony's maid is washing his new car. 16. The children are playing in the field. 17. Samuel was eating when I came in. 18. We have been living here since 1959. 2.“Be + 过去分词”以组成被动语态(The Passive Voice),如: 19. Her money in the drawer was stolen. 20. A number of good jobs are taken up byforeigners. 21. David studied in Taiwan but has been trained as a language lecturer in America. 22. Can all the wonderful birds be found in our Bird Park 23. The disobedient boy was told to stand out- side the classroom. 24. Steps are being taken to reduce traffic con- gestion during peak hours. 25. Dishonest students will be immediately dealt with.
