Presentation

need表示“需要”或“必须”，通常用于否定句和疑问句。例如：

1．You needn't do it again．你不需要再做了。

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。

“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

另外，“need”后还可以直接跟名词。请看下面的例子：

1．We need to collect the parcel before we leave for England．去

英国之前，我们需要收拾好行李。

2．We need to tell him the truth．我们需要告诉他真相。

3．My car needs repairing．我的汽车需要修理。

4．The flowers need watering．这些花需要浇水。

5．His leather shoes needs to be mended．他的皮鞋需要修补。

6．Her room needs cleaning．她的房间需要打扫。

Does he need to go so soon?

他这么快就要走吗?

He doesn't need to go.

他不需要走。

教后记

needn't do 中，need是情态动词：need do (情态动词+动词訽形）

don't need to do 中，need是行为动词，need to do ——>（否）don't need to do ,（因为行为动词否定都是don't /doesn't/didin't +动词訽形）

判断"need"的情态动词和行为动词，就看后面的是do or to do

My brother was very ill, so I had to call the doctor in the middle of the night.

我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事)

He said that they must work hard. 他说他们必须努力工作。（主观上要做这件事）

You don't have to tell him about it.

你不一定要把此事告诉他。

You mustn't tell him about it.

你一定不要把这件事告诉他
