过去进行时主要表示过去某一时刻正在进行的动作，或表示过去某一阶段一直在进行的动作，现在和小编一起来看一下经典练习题吧！ 1、Mary ___ a dress when she cut her finger.
A. made B. is making C. was making D. makes
答案C. 割伤手指是已发生的事情,应用过去时.同 时,when表时间的同时性,"玛丽在做衣服时"提供事情发生的背景,因此用过去进行时. 2、As she ___ the newspaper, Granny ___ asleep.
A. read； was falling B. was reading； fell C. was reading； was falling D. read；fell
答案B.句中的as = when, while,意为"当……之时".描述一件事发生的背景时,用过去进行；一个长动作发生的时候,另一个短动作发生.句意为 "在她看报纸时,奶奶睡着了."句中的 fell (fall的过去时),是系动词,后跟形容词,如：fall sick. 3、Tom ___ into the house when no one ___ .
A. slipped, was looking B. Had slipped, looked
C. slipped, had looked D. was slipping, looked
答案A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。 4、The student ______ to move the bag of rice _______ he heard the sound of a motorbike .
A was running... when B. was running ... while C. runs ... when D. ran ... while
答案A be(was, were ) + v.ing when .....表示when后面的动作突然发生。其实when在这里是并列连词， 而非从属连词。 5、—Is there anything wrong ，Bob？you look sad。 —Oh，nothing much. In fact ，I____ of my friend back home。
A、have just thought B、was just thinking C、would just thinking D、will just be thinking
答案B 由对话语境可知， 一方发觉另一方不对劲，“怎么了？你看上去不高兴。” 故回答时用过去进行时与 just 搭配，表示说话人说刚才在思念家乡的朋友。 以上就是小编为大家精心总结的练习题，希望同学们学会举一反三，分清楚易混淆的时态，勤加练习，及时巩固。 |
