我原來以為可以,查了一下語法書,不行.
"It is"的contraction (縮約形式)是"it's"：
It's raining now.(= It is raining.)
"It has"的縮寫形式也是"it's"：
It's been raining for two hours.(= It has been raining for two hours .)
那么"it was"的縮寫形式是什么呢?
在古代英文里,"it was"可 以被縮寫成"'twas"：
'Twas raining.(= It was raining.)
'Twas thy love that brought us together.(= It was your love that brought us together.)
但在現(xiàn)代英文里,"it was"并沒有縮寫形式；"'twas"這個字已被淘汰了.
換句話說,"it's"可以是"it is"或"it has",但不能是"it was".
