He ___ the classroom now.He can clean it this afternoon.A、don`t need clean B、need not to clean
C、need not clean D、needs not clean
正确答案是选C,而我选B,这些真弄不清楚了,

He ___ the classroom now.He can clean it this afternoon.A、don`t need clean B、need not to cleanC、need not clean D、needs not clean正确答案是选C,而我选B,这些真弄不清楚了,
本题的意思是他不需要现在打扫房间.need 在这里做的是情态动词.情态动词后面只能加动词原形,所以只能是need do; 否定式为need not do; 假使这里面用的实意动词,否定式应为 don't need to do--四个选项中也没有这个答案 所以无论如何B答案都是错误的

选C意思是不必,“他现在不必打扫教室,他下午能打扫”。
情态动词的否定形式:情态动词+not即可判断AD错误;
情态动词的肯定形式:情态动词+动词原形可判断B错误。

need有两种形式:一种是实义动词,一种是情态动词。作实义动词时的否定形式:don't need to do 而作情态动词时的否定形式:need not do所以才选C而不选B,懂了么?

need 有两个词性,(1)实义动词,其用法是need to do sth.,那么它的否定式必须借助助动词do,所以否定式是don't need to do sth.。
(2)情态动词, 其用法是后面加动词原形,即need do sth.。否定就直接在need 后面加not,所以是need not do sth."不必做某事"。...

need 有两个词性,(1)实义动词,其用法是need to do sth.,那么它的否定式必须借助助动词do,所以否定式是don't need to do sth.。
(2)情态动词, 其用法是后面加动词原形,即need do sth.。否定就直接在need 后面加not,所以是need not do sth."不必做某事"。

收起

这里的need和can 、will、must 一样属于情态动词,否定句就是need not do sth,
need假如是动词的话就是do not need to do sth ,只有这两种形式,根据问题选择哪种合适。
