问题描述:
Students _____ go to school during there two months.
A、needn‘t to B、needn’t C、don‘t needD、not need
怎么做?
need在各种情况下的用法是什么?
求详细
答
B need 作情态动词的搭配是need do sth/ needn't do sth
做实义动词或行为动词时是need to do sth/don't need to do sth
,所以只有B对我老是做选择题分不清need什么时候是情态什么时候是行为动词那没什么关系啊,肯定句的时候两个都可以,否定句要to就是行为动词(就用don't need to do ),没to就是情态动词(用needn't do 就可以了)
