need”作为情态动词的用法
一、need表示“需要”或“必须”,通常用于否定句,疑问句,条件句.例如:1.You needn't do it again.你不需要重复做了.2.He needn't worry about it.这件事他无需担心.3.Need he do this homework first?他需要先做这些作业吗?4.Need they fill in the form?他们需要填表吗?二、在否定句中,可以用need的否定形式+不定式完成体.例如:1.We needn't have worried.其实我们不必要慌.2.You needn't have mentioned it.你本来不必提起这件事.3.You needn't have said that when he asked.当他问的时候,你其实不必要说.三、needn't后的不定式间或也能用进行式或被动语态.例如:1.He needn't be standing in the rain.他不必要站在雨中.2.We needn't be waiting in this place.我们不必要在这儿等.3.The hedges needn't be trimmed thisweek.本周树蓠不必要整修.四、其一般疑问句的答语,肯定用must,否定用needn't.Need I go with her?我需要和他一起去吗?Yes,you must.是的,你需要去.No,you needn't.不,你不必去.
编辑本段“need”作为实义动词时,通常用法是
人+need +to do 物+need +doing 物+need +to be done 例如:The room needs cleaning = The room needs to be cleaned.房间需要打扫了.另外,“need”作实义动词时后还可以直接跟名词.请看下面的例子:It is a question that needs very careful consideration.这是一个需要慎重考虑的问题 很简单的方法区别情态动词与实义动词:当need为情态动词时,意思是“必要”,否定为"needn't",后面大多接动名词,表示动作; 当need为实义动词时,意思是“需要”,否定为"don't need",后面大多跟名词.

初中情态动词其实是一个重点,或者说似乎一直是重点。至少在我们这里(人教版)。 need可以作为实意动词,是及物动词,后加动词不定式to do或名词。否定形式常考与情态动词的区别,要区分开,实意动词否定形式是don't need to do不需要去做某事 need也是情态动词。后直接加动词原型。否定形式为needn't,needn't do sth不必做某事 一般情况下肯定的都用实意动词(need to do sth需要做某事) 一般用must提问的否定回答是no,……needn't. 或还有一个用法,sth need to be done = sth need doing 某物需要被…… 例如flowers need to be watered.= flowers need watering. 这个也是需要记住的。要是稍微need上稍微加点难度应该就会考到。
