needn’t是英式 don’t need是美式 I needn’t go home now.(英) I don't need to go home now.(美) 你只需要知道直接否定的是英式即可,需要加助动词的是美式 同理的还有 I haven’t any money=I haven’t got any money(英) I don't have any money(美) Have you got a pen?(英) Do you have a pen?(美) I’ve got a pen.(英) I have a pen.(美) 另外表达过去做过某事时,时态上也有所不同,美式多用一般过去式去表达英式那种复杂的现在完成时 Have you gone to the paty yesterday?(英) Did you go to the party yesterday?(美) “shall”和“will”用法不同,陈述句英式英语用shall表达自己和我们将...美式英语用will表达全部,疑问句表达自己和我们英式用Shall开头,但美式不用Will开头,用Should. Shall I go to the pary?(英) Should I go to the pary?(美) I shall go to the party.(英) I will go to the party.(美)
前者是没有必要做某事(比较委婉),后者是不需要做,前者的固定搭配是needn't do something后者的固定搭配是 don't need to do something
