语法点一

1．用作实义动词

(1) 有人称和数的变化，其第三人称单数形式为needs，变为否定句或疑问句时要用助动词do/does/did。

(2)后跟名词、代词、不定式或动名词作宾语，当need的主语与need后面的动词之间是被动关系时，need后面接不定式的被动形式或动名词的主动形式。

You don't need to worry about me. 你不必担心我。

The room needs cleaning/to be cleaned, but I only have time on Sunday. 房间需要打扫，但是我只有星期天有空。

2．用作情态动词

(1)need表示“需要”或“必须”，通常用于否定句和疑问句。

You needn't do it again. 你不必再做了。

Need he do his homework first? 他需要先做作业吗？

(2)由must引起的一般疑问句中，否定答语可用needn't, 意为“没必要”。

—Must I do the work now? —No, you needn't. ——我现在必须做这项工作吗？

——不，你不必。

(3)在need引起的一般疑问句中，肯定回答用must，否定回答用needn't。

—Need I go there too? —Yes, you must./No, you needn't. ——我也需要去那儿吗？

——是的，你必须去。/不，你不必去。
