如：I was cooking the dinner while he was playing the piano.总结：动作持续的时间较长用进行时，较短的用过去时。
1．As she ____the newspaper ,Granny ____ asleep .(95)A. read /was falling B .was reading /fellC. Was reading /was fallingD. read/fell分析：时间从句的动作长，而“入睡”动作短，故前者用过去进行时，而较短动词用一般过去时，选B2．Tom ___ into the house when no one ___ .A. slipped/was lookingB. Had slipped /lookedC. slipped/had lookedD. was slipping /looked分析：此题先要理解好when ，表“此时”，说明主句中slipped是较短行为，而look是较长行为的片断，即汤姆溜进房子，此时没人瞧见，故选A为正确。
