U6T2语法归纳 when &. while （一）when 的用法 　　 如果只从现象来看，when 从句用得最多的是一般过去时，而主句的时态没有限制, 根据具体情况而定。 1. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。 2. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ 3. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。 4. When the manager comes here for a visit next week, I’ll talk with him about this. 下周，经理来这参观时，我会和他谈谈此事。 5. When he arrives, I’d like you to meet him. 当他来的时候，我想让你去见见他。 (二)while 的用法 　　 相比于when 来说，while 从句的侧重点就不一样了。while 从句的侧重点在于描述动作 正在发生的状态，它的意思是：当while 事件正在发生的时候，另一件事如何如何。所以， while 从句一般用的是正在进行时。而另一件事的状态没有硬性的要求，根据具体情况而定。 例如：1. While my wife was reading the newspaper, I was watching TV. 当妻子正在看报纸的时候，我正在看电视。 2. While Jim was mending his bike, Lin Tao came to see him. 　正当吉姆修自行车时，林涛来看他。 3. While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。 （三）延续性动词&非延续性动词： 1.延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。如： learn, work, walk, keep, have, wait, watch, sing, read, sleep, live, stay 2.终止性动词也称非延续性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后 立即结束。如：open, die, close, begin, finish, come, go, move, borrow, lend, buy。 （四）辨析： 1. I was reading a book when she came into my room. 这句话当中的came可以换成was coming吗？为什么？ 不能，因为come是非延续性动词，无进行时态。 注意： While/When Jim was mending his bike, Lin Tao came to see him. =Jim was mending his bike when Lin Tao came to see him. 从这两个例子当中可以总结出while后面必须跟延续性动词，when后面既可以跟延续性动词， 也可跟非延续性动词。 Section A 随堂练习（一） 一、用when或while填空。 1. she was cooking dinner, I came into the kitchen. 2.
