11、cher came in just now.总结：1. 在这些句子中，when引导的句子表示过去的某一个具体的时间，when从句用一般过去时，而它的主句用过去进行时。2. 但是若强调某个动作正在进行中时，又发生了别的动作，用when从句。when从句必用过去进行时，主句用一般过去时。若表示在when从句正进行期间又发生了主句的动作，此时，when=while,表时间段。e.g. _ _we were having supper, the light went out._he was riding a bike, he fell off and hurt his leg.3. 若主、从句两个延续

12、动作同时进行，用while，则主句与从句都用进行时，此时，while译为“而” “一边，一边”。e.g. He was reading the newspaper _ _ I was studying.4. 以小组形式提出疑问，小组讨论，组间交流答疑。Questions: _【当堂检测】 1. 单项选择题( )1.
