be动词和实意动词
俩个不能同时用是吧?那为啥说I am writing to you to .这里的am 和 writing 不都是动词吗．．怎么在一起列

动词根据构成谓语方式可分成两种：1构成合成谓语的特殊动词.共有12个.2.可以单独构成谓语的普通实义动词.
be动词有双重属性,当be是特殊助动词时,可以和doing/done/to do/going to do/used to doing/构成合成谓语.
He is leaving.
The work is finished.
The president is to visit your country next week.
I am going to have a trip in a few days.
当be本身是实义动词时解释为是,在等含义时,就不能再和其他实义动词连用了.通常要把那个动词变成to do或doing来做表语了.
To see is to believe.
Seeing is believing.

be动词和实意动词俩个不能同时用是吧?那为啥说I am writing to you to .这里的am 和 writi I am determined to stay here.这里面的determined不是动词吗,为什么还要加个be动词 i am looking forward to hearing from you!这里的TO后面应该是用动词原形hear be动词不能单独做谓语,那I am happy的谓语是什么? 系动词be,我不理解I am English 我是英国人为啥要有个am 还有 I am tired 我累了为啥要有个小学英语教学 BE动词和实意动词英语Be动词和实意动词用法 i am blue和 I can do 这里的 can和am在句中是谓语吗是实义动词吗英语实意动词和be动词的用法 be动词作谓语的句子和实意动词作谓语的句子各10个 I am going to --(be) a doctor用动词的适当形式填空 I am writing to express my apology to you.
