狀語從句教案

狀語從句（2h）教學(xué)目標(biāo)：掌握9大狀語從句及其中重要的引導(dǎo)詞與句型。由于高考中狀語從句經(jīng)常和從句的時態(tài)語態(tài)，動詞短語的搭配，以及狀語從句的省略，虛擬語氣與倒裝一起考查。因此必須掌握好：1時間狀語從句中各種引導(dǎo)詞引導(dǎo)的主句與從句的時態(tài)的判斷2地點(diǎn)狀語從句中表示抽象含義時從句必須在主句之前3原因狀語從句中because，as，nowthat的位置問題4目的狀語從句中的sothat與在結(jié)果狀語從句中的區(qū)分5結(jié)果狀語從句中的so/such…that…的特殊結(jié)構(gòu)及其倒裝6條件狀語從句中的if，unless的用法7方式狀語從句中的虛擬語氣的用法8讓步狀語從句中的as,though做引導(dǎo)詞時的倒裝用法教學(xué)重點(diǎn)：1掌握常用的狀語從句中的引導(dǎo)詞2判斷狀語從句中的時態(tài)3狀語從句中的倒裝情況：nosooner…than,hardly/scarcely…when,not…until用于句首時的倒裝；結(jié)果狀語從句中so/such置于句首時的倒裝情況；as/though引導(dǎo)的讓步狀語從句的倒裝情況4asif/though引導(dǎo)的方式狀語從句中的虛擬語氣教學(xué)進(jìn)程：導(dǎo)入：狀語從句在句子中作狀語，修飾謂語。㈠時間狀語從句⒈回顧有哪些詞可以引導(dǎo)時間狀語從句—when,while,as表示“當(dāng)…時”;immediately,instantly,assoonas,directly,themoment,nosoonerthan,hardlywhen,scarcelywhen,once表示“一…就…”；till,until,notuntil表示“直到…才”；before表示“還沒來得及…就…”，“不到…就…”；since表示“自從…”；everytime,eachtime,nexttime,thefirsttime,anytime,allthetime表示“每當(dāng)…”，“每次…”，“下次…”等等⒉狀語從句中的時態(tài)的判斷方法：⑴過去，現(xiàn)在，將來⑵延續(xù)性與非延續(xù)性/時間點(diǎn)與時間段⑶主從句中的謂語動詞的先后關(guān)系⑷判斷開始時間與截止時間⒊when,while,as都可以表示主從句動作同時進(jìn)行(口頭造句舉例)如：whenthemusicfadesaway,peopletideaway.Shesattherealonewhileotherswerealldancing.Hedancesjoyfullyasthemusicgoes.當(dāng)主句動詞為短暫性，從句動詞用延續(xù)性動詞的進(jìn)行時態(tài)表示一段時間內(nèi)的動作時，三個詞可互換。如上面的第二個句子。When可引導(dǎo)持續(xù)動作亦可引導(dǎo)短暫動作。如WhenIwasyoung,IusedtoplayBarbiedolls.While引導(dǎo)的必須為延續(xù)性動詞，側(cè)重和主句中的動詞相對比。如Whilehewasmakingthebreakfast,hiswifewassleeping.As可以指主從句的動作交替進(jìn)行。如Shefeelssomeone’sfollowingher,soshewalkedfastaslotokedback.⒋“一…就…”⑴Themomentsheheardthemusicshelikedmost,shestooduptodance.⑵HardlyhadtheCinderellagothomewhentheclockknocked12o’clock.⑶AssoonasIgetthere,I’llletyouknow.(強(qiáng)調(diào)當(dāng)nosoonerthan和hardlywhen,scarcelywhen提到句首時要用到倒裝)⒌till,until,not…until⑴肯定句：主謂語必須為延續(xù)性動詞Youcandancetoyourjoyuntilyoufeeltired.⑵否定句：主從句必須為非延續(xù)性動詞Youcan’tmarryhimuntilIsayyes.（強(qiáng)調(diào)till不能放句首，until可以）6.before⑴Ihadn’tfinishedmysentencebeforeheturnedhisbacktome。⑵Itwillbe2yearsbeforeIgetback.7.sinceIhaven’tspokentohimsince1yearago.Itis3yearssinceIsmoked.Ithasbeen3yearssinceIsmoked.8．Everytime…歌詞：everytimeIleavetoheadoutontheroad,Iwannatakeyouwithme,savemefromthecold.練習(xí)：1Weusuallycallsomeoneagreenhand____(當(dāng)他沒有經(jīng)驗(yàn))hisjob.(experienced)2IwasspeakingtoAnnonthephone___（突然我們短線了)(cut)㈡地點(diǎn)狀語從句表示抽象含義時，從句需在主句前。如Wheretherearegirls,thereisgossip.
