What do you like to collect in the future? 9. What is the most mon/unusual/interesting hobby? ?、螅Z法 現(xiàn)在完成進(jìn)行時(shí) 二.【重難點(diǎn)分析】 1. 現(xiàn)在完成進(jìn)行時(shí) 構(gòu)成：肯定句：主語 + have / has been + doing 否定句：主語+have/has+not+been+doing 一般疑問句：Have/Has+主語+been+doing? 現(xiàn)在完成進(jìn)行時(shí)表達(dá)“某一動作從過去開始一直持續(xù)到現(xiàn)在，有可能還要持續(xù)下去”，現(xiàn)在完成進(jìn)行時(shí)的句子中多用延續(xù)性動詞，如：live，learn，study，work等?！ ?1)I have been learning English for ten years. 我學(xué)英語已經(jīng)十年了。 (2)She has been skating for four hours. 到現(xiàn)在為止她滑冰已經(jīng)有四個(gè)小時(shí)了。 (3)I have been collecting stamps since I was ten years old. 我從十歲起就一直在集郵?！ ≡谶@幾個(gè)句子中，have和has是助動詞，疑問形式需把助動詞提前，否定形式在have或has后面加not，have not和has not可以分別縮寫成haven’t和hasn’t，如： (1)Have you been doing your homework since this morning? 從今天早晨起你就一直在寫作業(yè)吧？ (2)Has he been writing the letters to his friend? 他是一直在給他的朋友寫信嗎？ (3)I haven’t been seeing films for a long time. 我有很長時(shí)間沒有看電影了?！ ?（表明沒有看電影這個(gè)動作從過去一直持續(xù)到現(xiàn)在，還要繼續(xù)持續(xù)下去。） ?。骸 ?1)現(xiàn)在完成時(shí)強(qiáng)調(diào)動作的完成，而現(xiàn)在完成進(jìn)行時(shí)側(cè)重的是動作的持續(xù)進(jìn)行?！ ?I have read a book about birds. （已經(jīng)讀完） I have been reading a book about birds.（一直都在讀，現(xiàn)在還在讀，有可能會繼續(xù)讀下去） (2)兩種時(shí)態(tài)都有延續(xù)性， 但現(xiàn)在完成時(shí)往往只說明一個(gè)事實(shí)，一種影響或結(jié)果，無感情色彩；現(xiàn)在完成進(jìn)行時(shí)表示一個(gè)動作的延續(xù)、重復(fù)，有時(shí)有一定的感情色彩。 She has been singing all the day. 她都唱了一整天了。（抱怨、厭煩） 三.【重點(diǎn)詞匯】 1. since的用法： (1)conj． ?、?引導(dǎo)時(shí)間狀語從句，從句中常用過去時(shí)，主句用一般時(shí)態(tài)或完成時(shí))自從……以來；……以后 It was years since l had seen her．自從我見到她(到那時(shí))又過去好幾年了?！ is just a week since we arrived here．我們到這兒剛好有一周了。②(引起原因狀語從句，通常
