求答案，简略原因​

对不起对不起，我今天提问太多了，没办法问了，所以在这里一次问完，悬赏会加的：
I can't see anybody in the playground.(同义句转换）
We passed in our final exams.We had a long summer holiday.（用过去完成时合并句子）
She asked me :"Have you ever benn to Hong Kng?"（用if变为宾语从句）

Answer 1

1. My mother was surprised what I ( had ) already ( done ).
原因：时间副词 already 通常要与 完成时态连用。又因为 主句是一般过去时，所以，从句就要用过去完成时态。

2. He put on his coat and ( left ) the room.
原因：动词 put 和 leave 是并列关系，既然 put 用一般过去时态，那么 leave 也要用一般过去时态。
3. Those two thieves ( had run away ) before the police ( arrived ).
原因：小偷”逃走“这个动作发生在警察”到来“之前，是发生”在过去的过去“的动作，所以，第一空用过去完成时态，第二空用一般过去时态。
