小编给大家带来公共英语考试二级口语辅导练习(15),希望对大家有所帮助。下面就请大家跟随小编的脚步一起来看看吧。希望各位备考公共英语二级的小伙伴们都能顺利上岸~ 用一般过去时代替完成时 1)两个动作如按顺序发生,又不强调先后,或用then,and,but 等连词时,多用一般过去时。 When she saw the mouse,she screamed. My aunt gave me a hat and I lost it. 2 ) 两个动作相继发生,可用一般过去时;如一、个动作需要若干时间完成,用过去完成时。 When I heard the news, I was very excited. 3)叙述历史事实,可不用过去完成时,而只用一般过去时。 Our teacher told us that Columbus discovered America in 1492. 过去完成时典型例题 The students ___ busily when Miss Brown went to get a book she ___ in the office. A. had written, left B. were writing, has left C. had written, had left D. were writing, had left 答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前,因此"忘了书"这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在"同学们正忙于……"这一背景下,when所引导的动作发生。因此前一句应用过去进行时。
注意: had no … when还没等…… 就…… had no sooner… than刚…… 就…… He had no sooner bought the car than he sold it.
