介词是中考英语的“隐性杀手”，虽然分值不大（约3-5分），但考查频率极高，且错误往往出现在最简单的题目上。近三年真题显示，考查重点集中在：① 时间介词 in/on/at 的辨析；② 地点介词 in/on/at/to 的辨析；③ 方式介词 by/with/in 的辨析；④ 动词+介词固定搭配（look forward to, be interested in, depend on 等）；⑤ 介词短语在语境中的运用。2026年预计会加大在校园生活、传统文化、科技创新语境下的综合考查，尤其是易混介词在长难句中的辨析，将是高分冲刺的关键。一线教师观察·来自课堂的真实困惑我教了十几年毕业班，发现学生对介词的困惑主要集中在四个“灵魂拷问”：•in, on, at 到底怎么分？早上到底是 in the morning 还是 on the morning？•地点介词in/on/at/to 有什么区别？为什么“在树上”要用 in 或 on？•by, with, in 都表示“用”，到底什么时候用哪个？•那么多动词+介词的固定搭配，记不住怎么办？这些困惑的背后，其实是学生没建立“类别记忆+语境判断”的思维模式。下面的“介词分类表”和“高频搭配清单”是我从无数错题中总结出来的，学生用了都说“原来介词这么有规律”。
