    (你的问题在于:NEED情态动词和行为动词的区别没有弄清.看一下,下面的内容也许会帮助你区别NEED情态动词和行为动词)

    一、作情态动词

    1.need作情态动词无人称或数的变化,后接动词原形,多用于否定句和疑问句中.如:You needn't worry.你不必担心.

    2.由need引出的一般疑问句,肯定回答常用must或have to;否定答语常用needn't.如:

    —Need I answer the question?我需要回答那个问题吗?

    —Yes,you must./Yes,you have to.是的,你必须回答./是的,你得回答./No,you needn't.不,不必了.

    3.由must引出的一般疑问句,肯定回答用must,否定答语用needn't或don't have to.如:

    —Must I do the work now?我必须现在干这个活吗?

    —Yes,you must /have to.是的,你必须做./No,you needn't /don't have to.不,你现在不必做.

    二、作行为动词

    need 作为行为动词有人称和数的变化,后面可接名词、代词、动名词及带to 的动词不定式;可用于肯定句、疑问句和否定句中,如:She needs help.她需要帮助.I don't need to see the doctor.我不需要看病.—Do you need to go at once?你需要马上走吗?

    —Yes,I do.是的,我得马上去.

    —No,I don't.不,不用马上走.
