1、時間狀語從句
(1)as、when、while用法。
as表示“當(dāng)…的時候”, 往往和when/ while通用, 但它著重強調(diào)主句與從句的動作或事情同時或幾乎同時發(fā)生。 She came up as I was cooking.(同時)
The runners started as the gun went off.(幾乎同時)
when (at or during the time that )既可以表示在某一點的時候, 又可表示在某一段時間內(nèi), 主 句與從句的動作或事情可以同時發(fā)生也可以先后發(fā)生。 It was raining when we arrived.(指時間點)When we were at school, we went to the library every day.(在一段時間內(nèi))
