need用法一用作实义动词1need sth.这是need最常见的用法之一，其后的宾语可以是名词，也可以是代词。如：1). The soup needs salt.2). They dont need afraid any more. 3). Does he need any help? 2need doing 与 need to be done通常物做主语，need后面可跟动名词作宾语，这种情况下应注意两点：.主动形式的动名词doing具有被动的含义；.该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如：4). The door needs painting. = The door needs to be painted. 5). Your car needs repairing. = Your car needs to be repaired. 3need to do sth.作为实义动词，need后面需要接带to的动词不定式,表示有义务或责任去做某事。如：6).
