she is,she was,she has的缩写形式都是she's?

首先讲讲she is和she was。这里的is和was其实是一样的性质,都是be动词,只是前者是一般式,后者是过去式。作be动词的时候,is一律可以缩写成's；was一律不能被缩写。因此,she is = she's,she was只能是she was。同理,I am = I'm,但是I was只能是I was。然后说she has。这里的has有两种解释,第一种是引导一般现在式：She has arrived in Shanghai。这里的has可以被缩写为she's。但是,仅限口语或者非书面场合。第二种是表示“拥有”：She has homework to do。这种情况下的has是不可以缩写的。同理,I have been here before = I've been here before,但是I have an apple的have不可以缩写。这下明白了吧~
