例如：Keep an eye on my little sister while I am away.我不在时，请照看一下我的小妹妹。
While we were watching TV, Jim came in. 我们看电视的时候，Jim 进来了。

when引导的宾语从句和时间状语从句一、when引导的宾语从句1. 概念- 在复合句中作宾语的从句叫宾语从句。
当when引导宾语从句时，它在从句中充当时间状语，表示“什么时候”的含义。
例如：I don't know when he will come back.（我不知道他什么时候回来。
）这里的“when he will come back”是整个句子的宾语，而when在这个宾语从句中表示“他回来”的时间。
2. 语序- 宾语从句要用陈述语序，即“连接词 + 主语+谓语+其他成分”。
例如：Can you tell me when the meeting will start?（你能告诉我会议什么时候开始吗？）而不能说成“Can you tell me when will the meeting start?”3. 时态- 当主句是一般现在时，宾语从句的时态根据实际情况而定，可以是一般现在时、一般过去时、将来时等。
例如：I wonder when he gets up every day.（我想知道他每天什么时候起床。
）这里从句用一般现在时表示经常的动作；She doesn't remember when she saw him last time.（她不记得上次什么时候见到他的了。
）这里从句用一般过去时表示过去发生的动作；He wants to know when they will leave for Paris.（他想知道他们什么时候动身去巴黎。
）这里从句用一般将来时表示将来的动作。
- 当主句是一般过去时，宾语从句要用相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。
例如：He asked me when I had finished my homework.（他问我什么时候完成作业的。
）这里从句用过去完成时，因为主句是一般过去时，“完成作业”这个动作发生在“问”之前。
