must,need,mustn't,needn't的用法

may 可能
can 能够
must 必须
Need 需要
这四个词应该用中文理解也能区别吧 不过从虚拟语气上来说 may最弱 must最强
may not 可能不
can't 不能够
mustn't 必须不
needn't 不需要
这里有必要做一下解释may not也就是个猜测 语气很弱
而can't除了表示不能 还能表示否定猜测 e.g. The light is off ,she can't be here. 灯灭了,她肯定不在这儿
must表肯定猜测 e.g.The light is still on ,she must be here. 灯还亮着,她肯定在这儿.
而Mustn't 不可乱用 通常只用在一些规章制度上 如果你违反了 比如违规停车就要用Mustn't
还有些对话中 must & need的交错回答也要领会意思
e.g. - must i go now?
- no, you needn't.
其实这里中文就可以辨清 .问我必须去么 回答你不用现在去.
但是也要看具体语境 有时是上级对下级之类的 也会用Mustn't回答.
