A．began B．has begun C．has been on D．is beginning 【答案】C 【详解】句意：——对不起，我迟到了。——没关系。会议只进行了几分钟。你没有错过太多。 根据“for just several minutes”可知，句子时态是现在完成时，且动词要用延续性动词，begin是短暂性动词，其延续性动词是be on，因此此处应用has been on。应填has been on。 49．Mr. Brown ________ his hometown since he ________ the army. A．has left; joined B．has been away from; has joined C．has been away from; joined D．left; joined 【答案】C 【详解】句意：布朗先生自从参军就离开了他的家乡。 has left已经离开；joined参加；has been away from已经离开；has joined已经参加；left离开。since引导时间状语从句用一般过去时，主句用现在完成时且需用延续性动词，第一空填has been away from，第二空填过去式joined。 50．—How long has Sue ______ Robert? —For more than three years. A．married B．been married to C．got married D．married to 【答案】B 【详解】句意：——苏和罗伯特结婚多久了？——三年多了。 married嫁/娶，过去式或过去分词，短暂性动作；been married to与……结婚，延续性动作；got married结婚，短暂性动作；married to是错误表达，前面需加be。“How long”提问时间段，谓语应用延续性动词表示状态，因此应选been married to。 2 立足新教材，自学有章法，练习有重点！ 1 立足新教材，自学有章法，练习有重点！ 学科网（北京）股份有限公司 $ 2025-2026学年一线教师制作新教材英语核心题型讲通练透系列资料，名师甄选！ 2025-2026学年一线教师制作新教材英语核心题型讲通练透系列资料，名师甄选！ Unit 7 A Good Read 单元Grammar：现在完成时易错题精练50题   知   识   梳   理 语法名称 核心定义 基本结构 核心用法（分点） 时态标志词 现在完成时 表示过去发生的动作对现在造成的影响或结果，或从过去开始持续到现在的动作/状态。 1. 肯定句：主语+have/has+过去分词 2. 否定句：主语+haven’t/hasn’t+过去分词 3. 一般疑问句：Have/Has+主语+过去分词？ 1. 影响型：强调过去动作对现在的影响（无明确时间点） 2. 持续型：强调动作从过去持续到现在（有持续时间） 3. 经历型：强调从过去到现在的经历（常与ever/never连用） for+时间段（如for 3 years） since+时间点/从句（如since 2020） already, yet, ever, never, just, recently   语   法   精   练 一、单项选择 1．He ________ never read a detective novel before, so he is curious about it.
