⑧needn't可以回答must开头的疑问句,只能用在肯定句中,可以直接加动词-ing

need doing:需要做,需要被做

① 这里need属于实义动词, 动词ing相当于名词来理解

② 有时态和人称变化,否定式为: don’t need doing

③ need doing 表达被动含义, 如: Your shoes need washing. 你的鞋子需(被)洗了

另外:want doing :也是用主动表示被动含义
它们的主语一定是物, 不是人: Your hair needs cuting.

need to be done---主语是人,也可以是物

1.never/not think of the risk she was taking
2.with sth.in one's possession
3.need doing
