36、r等表示一段時(shí)間的狀語連用。 試比較以下幾組句子，看有什么區(qū)別： A：Have you seen the film? B：Did you see the film?注意非延續(xù)性動(dòng)詞(瞬間動(dòng)詞)只能表示極其短暫的動(dòng)作，而沒有持續(xù)的長度。因此用于現(xiàn)在完成時(shí)，不能和表示一段時(shí)間的for或since連用，如果與表示一段時(shí)間的狀語連用，則要變?yōu)檠永m(xù)性動(dòng)詞，主要包括：buyhave，borrowkeep，diebe dead，beginbe on，come(go，arrive，get)be in /at，get upbe up，openbe away，joinbe in /be aan+名詞，finish
