在英语里be怎么用
不是am is are而是单独的be
不是am is are而是单独的be
e是一个多功能动词,在初级英语里可见四种用法:
功能一,系动词be
be为连系动词,中心词义是"是",句型为"主+系+表"结构.be的形式常用am,is,are(现在式);was,were(过去式);will/can/may/must be(助动词/情态动词+原形);have/has/had been(助动词+过去分词)等.如:
To help animals is helping people.(一般现在时)
The twins were very busy yesterday.(一般过去时)
It will be sunny tomorrow.(一般将来时)
She has been ill for over a week.(现在完成时)
功能二,助动词be
助动词be,无词义,辅助主要动词一起在句中作谓语动词.用法如下:
1.be+doing:构成进行时态,有现在和过去两种进行时态.如:
The girls is reading and copying the new words now.
Young Tom was always asking questions and trying out new ideas.
2.be+done:构成被动语态(主语是动作的承受者,done必须是及物动词).如:
Tea is grown in my hometown.(一般现在时的被动语态)
This building was built three years ago.(一般过去时的被动语态)
Our classroom has been cleaned and tidied already.(现在完成时的被动语态)
How could this kind of cakes be made in your home?(含情态动词的被动语态)
That is a day never to be forgotten.(动词不定式的被动语态)
3.be+going to do,表示"打算或将要做某事",be有现在和过去两种形式.如:
We are going to plant trees in the park.
I didn't know if she was going to come here.
4.be+to do,表示"按计划安排将要做某事".如:
The new shop is not to be opened till next Monday.
One night an angel came to Mary and told her that she was to have this special boy.
功能三,there be
there be句式为:there be+主语部分+状语部分,表示"某处存在某物",be常用现在时,过去时和将来时等.如:
Oh,cool!And there are many things to see.There is even a deer park in Sanya.
There are about 80 pyramids in Egypt.
Will there be a football match in your school next week?
功能四,实义be
可以将be视为实义动词,因为它具有实际的词义,如"成为;做;发生;举行;逗留;到达"等.如:
His daughter wants to be a doctor for animals in her twenties.
Kate's birthday party will be at half past six this evening.
Jim has been in China for more than two years,but he has not yet been to Yichang.

be在句中的用法有的句子里直接出现了“be”,不是am、is、are.它在句中表何意,怎么用?
be的用法 不是问作为be动词(am is are)时的形态 而是问以be这个单词出现时的用法
be的使用英语中的be怎么使用,为什么有的地方用be、being却不能用am,is,are,
求be的详细用法,非am is are,而是be.
be不是(am.is.are)吗,能用在句中吗
英语中be的用法be 这个单词该怎么用 不是be里面的 am is were 这些 就只是be 该怎么用
英语中的be在什么时候用,在什么是不用be用am is are?
be able to do 的be应该怎么用,直接用be还是用is am are is am are 跟 be 有什么区
在英语中,几时用be(am is are 的原型)
句子里什么时候用be(am,is,are)什么时候不用
英语中“be”的用法在英语中“be”什么时候要用am,is,are表示?什么时候可以直接用be表示?
be到底有没有过去式?不是am\is\are的过去式,就是be的.
