1.当我们要表达“需要做某事”时，
1）肯定句中need一般不用做情态动词,表达成need to do sth；
2）否定句和疑问句中，need可以用作情态动词,表达成 need not do sth或do not need to do sth和Need you do sth?
2.当我们要表达“需要某某”时，need只作实义动词，表达成need sth.
翻译：
The garden does not need watering/to be watered,as it rained last night.
或者：You needn't water the garden(You do not need to water the garden),as it rained last night.

实义动词need to do （注意它的被动形式是need doing)
情态动词need do

The garden needs watering,for it's rainny last night.(need doing表示被动）
The garden needn't be watered,for it's rainy last night.

need doing=need to be done
还有need 做情态动词时候就把他看成can may must就行了

the garden doesn't need to be watered, because it rained last night.
there is no need to water the garden, because it rained last night.

The garden need not be watered, because it rained last night.
