2026 届中考英语二轮专题复习
情态动词
【考情考向·近三年命题趋势】
情态动词是中考英语的必考高频考点。2023-2025年全国各地市真题卷显示,命题主要集中在对情态动词基本用法(能力/许可/必要)、推测用法(对现在/过去的推测)以及特殊句式(had better, used to等)的考查。本专题按考点分层设计,每个考点下设基础巩固和能力提升两个层级,帮助考生逐级突破。
【核心知识·考点分层精讲】
考点一:情态动词表能力、许可、必要(基础必会)
① can/could 表示能力(could 过去能力)、许可(Can I... )、可能性(It can be true.)。
② may/might 表示许可(May I... )、可能性(might 更委婉)、祝愿(May you...!)。
③ must/have to must 主观必须,否定 mustn't 禁止;have to 客观必须,否定 don't have to 不必。
④ should/ought to 表示应该、义务、建议。
⑤ need/dare 既可作情态(常用于否定疑问),也可作实义动词。
考点二:情态动词表推测(高频拉分点)
① 对现在/将来的推测: must(一定) > can(可能) > could/might(也许) > may(或许)。must 只用于肯定句;can't 表示“不可能”。
② 对过去的推测(情态动词+have done): must have done(过去一定做了),can't have done(过去不可能做了),may/might have done(过去可能做了),could have done(本可以做但未做)。
③ 易错警示: must 表推测不用于否定句;may 表推测不用于疑问句。
考点三:情态动词特殊用法 & 易混辨析(高分突破)
① shall/should 区别: shall 用于第一人称疑问句表征求意见,用于二三人称表允诺;should 表应该、按理推测。
② will/would 用法: will 表现在意愿、习惯;would 表过去意愿、委婉请求、过去习惯。
③ had better 的用法: had better (not) do sth.
④ used to / would 区别: used to 强调过去习惯且现在不再,would 只表过去习惯不强调今昔对比。
⑤ 情态动词+have done 虚拟用法: should have done 本应做未做,could have done 本可以做未做,needn't have done 本不必做却做了。
