【题目】句型转换 按括号内的要求转换下列句型，每空填一词。
【1】Must I leave here right away? (作否定回答)
No, _______ __________. You can leave an hour later.
【2】You must finish the work on time. (改为被动语态)

【答案】
【1】 you needn’t
【2】 be finished
【3】 have kept
【4】 What do
【5】 because of
【解析】
【1】句意：我必须马上离开这里吗？
考查含有情态动词must的疑问句的否定回答，must提问的句子，作否定回答要用No,主语+ needn't。故填(1). you (2). needn’t。
【2】句意：你必须按时完成工作。
考查被动语态。含有情态动词的句子，变被动语态的结构是情态动词+be+动词的过去分词，这里用情态动词must。finish的过去分词是finished完成。故填 (1). be (2). finished。
【3】句意：我两天前借了这本书。
原句是说两天前借了书，也就是借了两天了，可知动作发生在过去，对持续了一段时间，故用现在完成时have/has+过去分词，主语I，borrow是短暂性动词，不能与一段时间连用，故用keep，过去分词kept，故答案是 (1). have (2). kept 。
【4】句意：你将如何处理这辆旧车？
本题考查句型转换．根据句意和结构可知这句话使用do with处置，和what搭配。故填(1). What (2). do。
【5】句意：他没有上学。他病了。
分析句意，他没上学，是因为他病了，表示“因为”用because of(后加其后接名词、代词、动名词、what 从句等)。故填(1). because (2). Of。
辨析deal with和do with。
dowith与dealwith都可作“处置”讲。dowith常与连接代词what连用，而dealwith常与连接副词how连用，如：Idon’tknowhowtheydealwiththeproblem. =Idon’tknowwhattheydowiththeproblem.
