有的,你先要弄清need的用法,他有两个用法.
第一,need做情态动词,就和can,may一样,这时用need do sth,否定式是need not do sth
第二,need做实义动词,这时用need to do sth,否定式是dont need to do
所以这个题答案是D,B少了to,A多了to
有什么疑问还可以问我,我一直在线.

need 可以做使役动词，也可以做情态动词
作实义动词时否定需要借助助动词do

感觉B项不够地道

选D
need可以当情态动词表示需要，比must的语气弱一些。当用作情态动词时，否定直接变成needn't。不论是肯定还是否定，只要是情态动词跟动词的原型。所以D选项正确。
need当实意动词时，后面要加to才能跟动词，即need to do sth。若要否定，则直接用don't或者doesn't，即don't/doesn't need to do...

答案：D
分析：need

答案：D
分析：need
用法(1) “需要”的意思，做及物动词，后跟名词或不定式做宾语。否定形式借助于助动词，如don't need to do sth.; didn't need to do sth. 等。
用法(2) "需要”“必要”，做情态动词，其后直接跟动词原形，否定形式是needn't, 就跟其他普通的情态动词的否定形式构成一样，如can't, shouldn't, needn't 等。
A选项错在没有直接跟动词原形，因为从needn't上可以看出，它是按情态动词用法使用的，但后面又加了to,就违背了情态动词用法了，故不对。
B选项里don't need上看得出来，这是need作及物动词的用法，后跟不定式，所以应该是：don't need to come 才对呢。
