英语中should,would,must,need,can,may怎么用?否定句呢?
这些词有什么区别吗，

sb should+动词原型,译为应该.
would译为想要干什么.一般结构为sb would like to do sth .等于sb want to sth.
must译为必须,结构为sb must do sth.表示主观的必须做某事.have to 也是必须,不得不,但这是客观的必须,一定要干.
need译为需要,一般为sb need to do sth.也有sb need doing sth
may译为可以+动词原型.
can译为能,can+动词原型.等于sb be able to do sth.
他们的否定形式在词尾加not就好了 .缩写例如shouldn't,wouldn't,.
