Question

8．電影已經(jīng)開始十分鐘了The film has been on for ten minutes．．

Answer 1

分析 The film has been on for ten minutes．

解答 答案：The film has been on for ten minutes．這里的電影是十分鐘前開始的，已經(jīng)持續(xù)了十分鐘還會(huì)繼續(xù)下去，用現(xiàn)在完成時(shí)have/has+過去分詞，主語是單數(shù)The film，故用has，這里的開始begin是短暫性動(dòng)詞，這里是和一段時(shí)間for ten minutes十分鐘連用，需換成be on表狀態(tài)，be的過去分詞是been，故答案是The film has been on for ten minutes．

點(diǎn)評(píng) 這里要主語現(xiàn)在完成時(shí)中短暫性動(dòng)詞和持續(xù)性動(dòng)詞的互換，用"be+副詞"代終止性動(dòng)詞的有"be+on"代start，begin  2"be+up"代get up  
3"be+back（to）"代return to，come back to，go back to  4"be here （there）"代come（arrive，reach，get） here或go （arrive，reach，get） there等等
