Whatare“AdverbialClauses”?

在主從復(fù)合句中修飾主語中的動詞、形容詞、副詞等的從句叫做“狀語從句”。分類如下：狀語從句1.時間狀語從句2.地點狀語從句3.原因狀語從句4.條件狀語從句5.讓步狀語從句6.目的狀語從句7.結(jié)果狀語從句8.方式狀語從句9.比較狀語從句1)

常用連詞如下：as,when,while,till/until,not…until,before,since,after等。1.時間狀語從句1．when引導(dǎo)的從句：表示主句的動作和從句的動作同時發(fā)生，或從句的動作發(fā)生在主句動作之前。2．while引導(dǎo)的從句：表示“當(dāng)……過程中”，強調(diào)某一段時間內(nèi)主句和從句中謂語動詞所表示的動作在同一時期發(fā)生。由于while從句表示一個持續(xù)的行為，所以從句中要用持續(xù)性動詞，并且持續(xù)性動詞常用進行時態(tài)。3．a(chǎn)s引導(dǎo)的時間狀語從句：表示“當(dāng)……的時候；一邊……一邊……；隨著……”，其從句的主語與主句的主語往往是同一人或物。4．before引導(dǎo)的從句：一般表示主句的動作發(fā)生在從句動作之前。5．a(chǎn)fter引導(dǎo)的從句：表示主句的動作發(fā)生在從句動作之后。6．since引導(dǎo)的從句：表示“自從……以來”，從句中的動詞一般表示動作的起點，用過去時。主句中的動詞表示動作延續(xù)的情況，一般用現(xiàn)在完成時。7．until引導(dǎo)的從句：表示一個動作持續(xù)到某一時刻。8．a(chǎn)ssoonas引導(dǎo)的從句表示“一……就”，強調(diào)動作緊密相連。P541.before2.Afterbetiredout3.while4.while5.whenwhile,when,as辨析

While：引導(dǎo)的時間狀語從句只指一段時間，強調(diào)某一段時間內(nèi)，主從句動作同時發(fā)生。從句動詞常是延續(xù)性的When：既可以指一個時間點,也可以是一段時間，可表示主從句的動作同時或先后發(fā)生。從句動詞可以是延續(xù)性的，也可以是非延續(xù)性的。As：強調(diào)主句﹑從句動作相并發(fā)生,譯為”一邊…一邊…”或“隨著”1）as,when引導(dǎo)短暫性動作的動詞。Justas/Justwhen/WhenIstoppedmycar,amancameuptome.我剎車后，有一個人向我走來。2）當(dāng)從句的動作發(fā)生于主句動作之前，只能用when引導(dǎo)這個從句，不可用as或while。Whenyouhavefinishedyourwork,youmayhavearest.干完活后，你可以休息一下。3）從句表示“隨時間推移”連詞能用as，不用when或while。Asthedaywenton,theweathergotwarmer.日子一天天過去，天氣越變越暖。（1）While意為“在……期間”，從句的謂語必須是延續(xù)性動詞。Theplanehadleftwhenwegottotheairport.（2）表示帶有規(guī)律性的“每當(dāng)”，或者主從句動作有先后時，都只能用when.Whenwintercomes,itbecomescold.（3）表示“隨著”時間的推移，主從句的內(nèi)容是兩種變化的情況，只能用as.Asthedaywenton,theweathergotworse.1._______hereturned,hiswifewascooking.2._______hewasreading,hiswifewascooking.3.Wetalkedhappily_____wewalkedalong.4.__timegoesby,it'sgettingcolder.WhenWhileasAswhen,while,as的互換如果從句動作和主句動作同時發(fā)生，并且從句動作為延續(xù)性動詞時，when，while，as可以互換使用。1.When/While/Asweweredancing,astrangercamein.dance為延續(xù)性動詞2.ImetMrLias/when/whileIwaswalkingalongthestreet.

另外,when/while還作并列連詞,連接并列分句,while表示“而,可是”如:Ilikereading______mywifeenjoyswatchingTV.when表示"突然性"“就在這時”

在下列結(jié)構(gòu)中，表示某件事正在發(fā)生或剛剛發(fā)生，另一動作同時發(fā)生。1.beabouttodo…when…2.bedoing…when…3.beonthepointofdoing…when…4.haddone…when…while.________________________(我們正要開始就在這時start)itbegantorain.2.____________________________momcamein.3.Ihadjustgothome____________________(就開始下雨）1.Wewereabouttostartwhen我正在玩電腦游戲就在這時媽媽進來了。Iwasplayingcomputergameswhenwhenitbegantoraintill一般用于肯定句中，until既可以用于肯定句，也可以用于否定句。

Iwillbeheretill/untilhecomesback.Iwon’tknowwhereheisuntilIgetaletterfromhim.

until/till區(qū)別“延續(xù)的動詞（肯定式）+until”表示“直到…為止”1.我一直睡到鬧鐘響為止._________________________.“非延續(xù)性動詞（否定式）+until”表示“直到┅才”2.直到他完成工作才上床睡______________________________________________IsleptuntiltheclockalarmedHedidn’tgotobeduntilhefinishedhiswork.since表示“自從…以來”，后接點時間，也可接一般過去時的句子構(gòu)成時間狀語從句，其主句用現(xiàn)在完成時主句中的謂語動詞要用延續(xù)性動詞。Hehasstudiedveryhardsincehecametoourschool.自從他來到我們學(xué)校，他學(xué)習(xí)就非常努力。P551.4.Itisthefirsttimethatsb.havedoneItwasthefirsttimethatsb.haddone
