我是这么总结的,
如果翻译成必需做某事,就是情态动词
如果翻译成需要做某事,就是实意动词
情态动词need只用于疑问句和否定句,用来表示有必要吗或没必要.肯定式是must.
不能接名词,只能和普通动词不定式构成合成谓语,无人称和时间变化.
Need you go there now
Yes,I must .No,I needn’t.
实意动词need不能提前疑问也不能加not否定,含义是需要.疑问和否定要借助于特殊动词do.可以接名词做宾语.也可以跟to do(=have to do) ,doing 做宾语.有时间和人称变化.跟-ing做宾语时,其主语往往是物,主动形式表被动结构.
I need to use the bathroom.
Do you need to have a book
Yes,I do .No,I don’t need to have a book.
I need a book.
Do you need a book
Yes,I need a book.No,I don’t need a book.
She needs your help.
Does she need your help
Yes,she does.No,she doesn’t.
He needed to take a taxi,or he would be late.
Did he need to take a taxi
Yes,he did.No,he didn’t.
Your shoe needs mending .
Does your shoe need mending
Yes,it does.No,it doesn’t.
