答案：

1. has been away . 用完成时表示持续动作时，要用可持续动词，不能用瞬间动词。leave是短暂性动词，be away表示持续性状态。

2. did … borrow . 后面回答者用的是现在完成时，说明是过去的动作或行为对现在产生的影响或结果，所以前面提问者要用一般过去时。

3. has lost . 此为并列句由so连接，前后时态要保持一致，尽管丢了自行车发生在过去，但是如果用一般过去时就不能做到前后时态一致。

4. to drive .此题考查 tell sb. not to do sth.

5. larger . 英语表达人口多要用 large ,人口少要用small .
