The past is need have, needn't have. It is used to say that something is or is not necessary. * need 作情态动词时，现在时均作 need，疑问式为 need you?，否定式为 need not (needn't)，过去时为 need have、needn't have，用以表示某事有必要或没有必要：◆Need I pay the whole amount now?我必须现在全部付清吗？ ● need (to have ) your ˈhead examined (informal ) to be crazy 发疯🔑 needBrE /niːd/ NAmE /niːd/ modal verb negative need not short form needn't used to state that sth is /was not necessary or that only very little is /was necessary ; used to ask if sth is /was necessary （表示没有必要或询问是否有必要）需要◆ ~ (not ) do sth You needn't bother asking Rick —I know he's too busy . 你不必费神去问里克，我知道他太忙了。◆ I need hardly tell you (= you must already know )that the work is dangerous . 这工作很危险，这就不用我说了。◆ If she wants anything , she need only ask . 她想要什么东西，只要开一下口就行了。◆ All you need bring are sheets . 你需要带的就是床单。◆ ~ (not ) have done sth You needn't have worried (= it was not necessary for you to worry , but you did ) —it all turned out fine . 你本不必担心，一切都很顺利。◆ Need you have paid so much ? 你用得着花那么多钱吗？modal verbsThe modal verbs are can, could, may, might, must, ought to, shall, should, will and would.
