以when和while引導的時間狀語從句1)

延續(xù)性動詞和非延續(xù)性動詞延續(xù)性動詞指動作可以延續(xù)一段時間,

而不是瞬間結(jié)束。如:

work、study、drink、eat等。非延續(xù)性動詞指動作極為短暫，瞬間結(jié)束。如:

start、begin、hit、jump、knock等。2)

在本單元中，出現(xiàn)了以when和while引導的時間狀語從句。when表示“當……的時候”。從句中既可用延續(xù)性動詞，又可用非延續(xù)性動詞，這些動詞既可以表示動作，又可表示狀態(tài)。從句中動作既可和主句的動作同時發(fā)生，又可在主句的動作之前或之后發(fā)生。如：MarywashavingdinnerwhenIsaw

her.Theboywasstillsleepingwhenhismothergothomeyesterday

morning.3)while表示“在……的時候”、“在……期間”。它強調(diào)主句的動作與從句的動作同時發(fā)生或主句的動作發(fā)生在從句的動作過程中。While從句中必須是表示動作或狀態(tài)的延續(xù)性動詞。如：TheweatherwasfinewhilewewereinBeijing.ShecalledwhileIwas

out.如果主句的動作在從句的動作過程中發(fā)生，從句常用進行時。如:此處缺少例子Jenniferwasreadingamagazine,her

night.他們昨晚寫了信給他們的朋友。(表達了他們已寫好的意思，整個寫的過程已完成)2)

當動作延續(xù)較長時間時或表示厭煩、贊美等感情色彩時,常用過去進行時表示。如：Hewasthinkingmoreofothersthanof

himself.他考慮別人的比考慮自己的多。(表示說話者贊揚的口氣)Theboywasalwaysmakingtroublethen

.那時，他總是惹麻煩。(表示說話者厭煩的口氣)過去進行時含義:
