need 的用法
need有用作情态动词、用作实意动词和作为名词的用法具体如下:
need用作情态动词时表“必须必要”的意思,后直接跟动词原型,且need无人称、数的变化(第三人称单数不加s),也没有非谓语形式(不定式、分词)。
例如:Need he bring his laptop tomorrow? 明天他必须带他的笔记本过来吗?
Come on, you needn't worry about it becuse it's not your fault. 行啦,你不必担心的因为那不是你的错。
She needn't have arrived so early, need she? 她本不必到得这么早,不是吗?
need用作实意动词
need + something 需要某物;need to do something 需要做某事;need doing = need to be done 需要……
need作为名词
need用作名词时,既可以是可数名词,也可以是不可数名词。例如:There's no need to cover such a long distance. 没必要走那么远的距离。
There's no need for me to break the window because I have the key. 我没必要打破窗户因为我有钥匙。
