2026小升初英语 · 情态动词专项训练 bestudent 2026 小升初英语 情态动词专项训练 高频考点 · 专项突破 · 孩子必刷 can / must / may / should 一网打尽 · 家长可直接打印 bestudent 情态动词真正底层逻辑 · 考前秒杀版 很多学生记不住「情态动词后用原形」。真正理解了原因，就再也不会错。 🔍 为什么情态动词后面永远跟动词原形？——一次听懂，终身不忘 情态动词的职责：表达语气（能力/必须/建议/许可）。 动词的职责：表达动作本身。 两个词各负其责，不能重叠！ 例：He can swim. can 已经负责表达「能力」，swim 只需要表达「游泳这个动作」。 swim 不需要再变形，直接用原形。 例：You must finish your homework. must 已经负责表达「必须」，finish 只需要表达「完成这个动作」。 finish 不需要加 s 或变形，直接用原形。 一句话记住：情态动词已经承担语气，后面动词只负责动作本身——永远用原形！ 情态动词秒杀口诀——背熟这两句，永不出错 情态动词已经承担语气，后面动词只负责动作——永远用原形！ 情态动词后：不加 s，不加 ed，不加 ing，不加 to——就是原形！ can = 能 must = 必须 should = 应该 may = 可以/可能 情态动词 表达语气 否定形式 经典例句 can 能力 / 请求许可 can't / cannot She can swim well. Can I use your pen? could 过去的能力 / 委婉请求 couldn't He could swim at age 5. Could you help me? must 必须 / 一定 （强烈语气） mustn't（禁止） don't have to（不必） You must finish homework. You mustn't run here. should 应该 / 建议 （语气较温和） shouldn't You should drink more water. You shouldn't stay up late. may 许可 / 可能性 may not May I come in? It may rain tomorrow. might 可能性（较小） might not He might be at home now. ⚡ 中国学生最容易错的三句——背熟绝不失分！ ❌ He can swims. ✅ He can swim. （can后原形，绝不加s） ❌ She should goes home. ✅ She should go home. （should后原形） ❌ Must I to finish it? ✅ Must I finish it? （情态动词后不加to） 第一部分 can 专项 · 能力与请求 can 表示「能力」或「请求许可」。后面动词永远用原形，否定用 can't。 ⚡ 90%学生会错！——can 后面动词不能加 s！ ❌ She can sings very well. ✅ She can sing very well. ❌ He can plays the piano. ✅ He can play the piano. ❌ Can she swims? ✅ Can she swim? 口诀：can 出现，后面动词就是原形，一个字母都不能多加！ 一、选择题（共8题） 💡 先确认是 can 的句子，再检查后面动词是否为原形。 1.
