need to的否定回答

很明显need在这里是实义动词,否定形式为don`t need to

don`t need to因为这里的need是实义动词，当它是情态动词时否定就是needn`t

所谓是does not还是do not 和need无关，而是看主语，如果是第一人称，第二人称，复数则用do not；如果是第三人称单数则用does not。

例如，I don`t need to finish the work today.
The boy does not need to pay for the ticket because he is 6 years old.

英文回答方法很直观，不管人家怎么问，否定就用相应的否定形式就可以了。如do not need to

don't need to or doesn't to

dont' need to

实义动词否定don't need to
作为情态动词的“need”的用法与其他情态动词“can”，“may”，“must”的用法基本相同
情态动词否定needn't
