(B)Didyouseethefilm"[說明]你看過這部電影嗎？(A)句強調的是被問者對劇情是否了解；(B)句強調的是看這部電影的動作是否發(fā)生過，并不強調是否知道其內容。HehaslivedinBeijingfor8years.

(B)HelivedinBeijingfor8years.[說明]他在住了8年。(A)句講的是到目前為止他在住了8年，可能還會繼續(xù)在住下去。(B)句講的是他在住過8年，現(xiàn)在不在了。練習一、抄寫動詞以及過去式和過去分詞。-.z.1.be_______________-_________________2.e_______________-_________________3.go_______________-_________________4.do_______________-_________________5.have_______________-_________________6.drink_______________-_________________7.give_______________-_________________8.eat_______________-_________________9.know_______________-_________________10.run_______________-_________________11.say_______________-_________________12.see_______________-_________________13.find_______________-_________________14.draw_______________-_________________15.get_______________-_________________16.hear_______________-_________________17.begin_______________-_________________18.buy_______________-_________________19.leave_______________-_________________20bee_______________-_________________21break_______________-_________________22bring_______________-_________________23build_______________-_________________24bite_______________-_________________25catch_______________-_________________26choose_______________-_________________27cut_______________-_________________28fall_______________-_________________29fly_______________-_________________30forget________________-_________________31grow_______________-_________________32hit_______________-_________________33hurt_______________-_________________34keep_______________-_________________35lend_______________-_________________36lose________________-_________________37meet_______________-_________________38put_______________-_________________39read_______________-_________________40ring_______________-_________________-.z.二、用for或since填空1.Mr.BrownhashadhisTV________15years.2.I’vetakendrivinglessons_________lastmonth.3.Mysisterhashadhercellphone________amonth.4.Myfriendshaven’tvisitedme___________mybirthday.5.Wehaven’tusedourcar________alongtime.6.Shehasn’thadagoodcupofcoffee_________years.7.Tomhaswornglasses_________hewas7yearsold.8.
