即:1、如果原句中有be动词、情态动词或者助动词,就以相应的be、情、助为准。例如:(1)He is at home. (有be动词)He isn't at home.Is he at home?(2)I can work it out.(有情态动词)I can't work it out.Can you work it out?(3)He has been there three times.(有助动词...
英语造句如何用BE动词和助动词?
What you have said does not relate to what we are concerned with now. (注:原题的标点符号有误)
英语中,改否定句或疑问句时,应该注意用好be动词、情态动词、助动词。规律是:先找be、情、助,无则“都打的(do, does, did)”。
即:1、如果原句中有be动词、情态动词或者助动词,就以相应的be、情、助为准。例如:
(1)He is at home. (有be动词)
He isn't at home.
Is he at home?
(2)I can work it out.(有情态动词)
I can't work it out.
Can you work it out?
(3)He has been there three times.(有助动词)
He hasn't been there three times.
Has he been there three times?
2.如果原句只有行为动词,那就要借助于助动词do,did或者did。例如:
(1)My grandpa lives in a villige.(注意动词还原)
My grandpa doesn't live in a villige.
Does your grandpa live in a villige.
(2)They had a good time there.(注意动词还原)
They didn't have a good time there.
Did they have a good time there?
(3) We work six hours a day.
We don't work six hours a day.
Do you work six hours a day?
您的这个句子的主语是What you have said ,即一个主语从句,从句子中我们知道谓语部分要用一般现在时态,故谓语动词要用现单三形式。
不知这样解释可否?2009-09-12
