小編給大家帶來(lái)公共英語(yǔ)考試二級口語(yǔ)輔導練習(15)，希望對大家有所幫助。下面就請大家跟隨小編的腳步一起來(lái)看看吧。希望各位備考公共英語(yǔ)二級的小伙伴們都能順利上岸~ 　　用一般過(guò)去時(shí)代替完成時(shí) 　　1)兩個(gè)動(dòng)作如按順序發(fā)生，又不強調先后，或用then，and，but 等連詞時(shí)，多用一般過(guò)去時(shí)。 　　When she saw the mouse，she screamed. 　　My aunt gave me a hat and I lost it. 　　2 ) 兩個(gè)動(dòng)作相繼發(fā)生，可用一般過(guò)去時(shí);如一、個(gè)動(dòng)作需要若干時(shí)間完成，用過(guò)去完成時(shí)。 　　When I heard the news, I was very excited. 　　3)敘述歷史事實(shí)，可不用過(guò)去完成時(shí)，而只用一般過(guò)去時(shí)。 　　Our teacher told us that Columbus discovered America in 1492. 　　過(guò)去完成時(shí)典型例題 　　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. "把書(shū)忘在辦公室"發(fā)生在"去取書(shū)"這一過(guò)去的動(dòng)作之前，因此"忘了書(shū)"這一動(dòng)作發(fā)生在過(guò)去的過(guò)去，用過(guò)去完成時(shí)。句中when表示的是時(shí)間的一點(diǎn)，表示在"同學(xué)們正忙于……"這一背景下，when所引導的動(dòng)作發(fā)生。因此前一句應用過(guò)去進(jìn)行時(shí)。

　　注意： 　　had no … when還沒(méi)等…… 就…… 　　had no sooner… than剛…… 就…… 　　He had no sooner bought the car than he sold it.
