was/were+v-ing過去進行時

過去進行時表示過去某一時刻或某段時間正在進行的動作。過去進行時由“was/were+動詞-ing形式”構(gòu)成。

時間標志詞：atthis/thattimeyesterday,at9:00yesterdaymorning,allnight等；或以when,while引導(dǎo)的時間狀語從句。構(gòu)成：基本結(jié)構(gòu)：主語+was/were+doing+其他。否定形式：主語+wasn’t/weren’t+doing+其他。一般疑問句：Was/Were+主語+doing+其他？肯定回答：Yes,主語+was/were.否定回答：No,主語+wasn’t/weren’t.特殊疑問句：特殊疑問詞+was/were+主語+doing+其他？

when和while引導(dǎo)的時間狀語從句中謂語動詞有什么區(qū)別？思考when引導(dǎo)的時間狀語從句可以表示一個時間點,也可以表示一個時間段。從句中可以用瞬間性動詞，也可以用延續(xù)性動詞。Itwassnowingwhenwegottotheairport.當我們到達機場時，天正下著雪。IlostmykeywhenIwaswalkinginthepark.我在公園散步時，

鑰匙丟了。whenwhilewhile引導(dǎo)的時間狀語從句常指一個時間段，從句中的動詞常為延續(xù)性的。while有時還可表示主句的動作與從句的動作同時發(fā)生。

Whilehewasreading,thephonerang.他正在看書時，電話鈴響了。Somestudentswerereadingwhileotherswerewriting.一些學(xué)生在讀書，另一些學(xué)生在寫字。

when和while的區(qū)別引導(dǎo)的時間狀語從句從句中的謂語動詞whenwhile指時間段，也可以指時間點可以是延續(xù)性動詞，也可以是瞬間性動詞一般指一段時間表狀態(tài)的延續(xù)性動詞when和while的區(qū)別注意：有時when可以代替while，而while

則不能代替when。when引導(dǎo)的時間狀語從句中，從句的動作和主句的動作可以同時發(fā)生，也可以一前一后先后發(fā)生；while則強調(diào)主句和從句的動作同時發(fā)生。when和while的區(qū)別when后面通常接一般過去時的從句，而while后接過去進行時的句子。1.Hewasreadinginthelibrarywhentherainstormcame.2.WhileLindawassleeping,JennywashelpingMarywithherhomework.注意：表示主從句正在進行的動作或狀態(tài)的對比時多用while：
