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(dǎo)的時間狀語從句。when表示“當(dāng)……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：MarywashavingdinnerwhenIsawher.Theboywasstillsleepingwhenhismothergothomeyesterdaymorning.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.ShecalledwhileIwasout.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:Whiletheboyswereplayingfootball,itrained.

2.過去進行時1.概念:表示過去某一時刻或某段時間內(nèi)正進行

的動作。2.構(gòu)成:was/were+動詞現(xiàn)在分詞3.用法:

a:表示某一時刻正進行的行為，與特定的過去

時間狀語連用，常見的時間有:at8lastnight,atthistime,atthattime,atthatmoment等Whatwereyoudoingat10yesterdaymorning?Iwaswritingalettertomyfatheratthatmoment.b:表示過去某段時間內(nèi)正進行的動作。e.g.Wewerebuildingahouselastwinter.Theywerewaitingforyouyesterday.否定句和疑問句：e.g.Wewere

not

sleepingathome.

Was

he

feelingwell?3.現(xiàn)在分詞的構(gòu)成一般動詞在詞尾加-ing，如go—going2)以不發(fā)音字母e結(jié)尾的動詞,先去掉e,再加-ingcome—coming

make—making

write—writing3)以重讀閉音節(jié)結(jié)尾的動詞，如果末尾以一個輔字母結(jié)尾，應(yīng)先雙寫這個字母，再加ing，x和w結(jié)尾的除外。get—getting

swim—swimming

show—showing4)以字母y結(jié)尾的單詞，直接加ing。如：

carrying

playingstudying5)以字母ie結(jié)尾的動詞，變ie為y，再加ing。

die→dying

lie→lying6)以元音字母加e結(jié)尾，或以e結(jié)尾，且e發(fā)音的動詞，直接加-ing。

see—seeing

be—being4.使用進行時態(tài)的注意事項1)一些動詞，如see,hear,love,like,know,remember,understand,have等表示感情、知覺和狀態(tài)的詞，一般不用于進行時態(tài)。2)在there和here引起的句子中，常用一般現(xiàn)在時代替現(xiàn)在進行時。e.g.Herecomesthebus.

Theregoesthebell.5.過去進行時和一般過去時的區(qū)別1)過去進行時表示過去正在進行的動作，而一般

過去時則表示一個完整的動作。如：Theywerewritingletterstotheirfriendslastnight.昨晚他們在寫信給他們的朋友。(沒有說明信是否寫完)Theywroteletterstotheirfriendslastnight.

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(dāng)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：Hewasthinkingmoreofothersthanofhimself.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:表示過去某個時刻

正在進行的動作。結(jié)構(gòu)：

was/were+doing例句：IwashavinganEnglishclassatthistimeyesterday.現(xiàn)在進行時含義:表示現(xiàn)在正在進行

的動作。結(jié)構(gòu)：

is/am/are+doing例句：IamhavinganEnglishclass.
