Reading

1.I thought , at the time, that this was just a story but then I witnessed it with my

own eyes many times.

at the time “那时候”，位置应在story之后，作时间状语，提前是为了强调，that this was just a story作thought的宾语。

2.On the afternoon I arrived at the station, as I was sorting out my accommodation, I

heard a huge noise coming from the bay.

在我到达捕鲸场的那个下午，正当我准备膳宿时，我听到一声巨响从海湾传来。as, when和while

1) as 强调主从句中谓语动词所表示的动作同时发生。从句表示"随时间推移"连词能用as，不用when 或while。

As the day went on, the weather got worse.

日子一天天过去，天气越变越坏。

2) when 可表示瞬间、时间段，主从句动作同时发生，也可以先后发生。当从句

的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或while。When you have finished your work, you may have a rest.

3) as, when 引导短暂性动作的动词。

Just as / Just when / When I stopped my car, a man came up to me.

4) while 用于同时进行的两个延续性动作相伴发生，常对同类动作进行对比。

accommodation
