学案名称 高考语法填空学案（八）连词与介词填空
使用时间 _____年_____月_____日 建议课时 2课时
学习目标 1. 掌握并列连词（and, but, or, so等）与从属连词（because, although, when等）的核心用法与区别。 2. 理解介词搭配的逻辑关系（时间、地点、原因、方式等），熟练运用高频固定搭配。 3. 能够在复杂句式中准确判断连词与介词的选择，避免常见错误。
重难点 重点：并列连词与从属连词的语义差异，介词搭配的固定性与语境判断。 难点：易混淆连词（如while vs. when）、易错介词搭配（如depend on vs. rely on）。
课堂导入 问题引导： 阅读句子： "He wants to study abroad, ___ he needs to improve his English." 提问： 为什么填“so”而不是“but”或“because”？ 并列连词与从属连词在句中的作用有何不同？ 目标：通过实例引发思考，引导学生理解连词与介词的核心逻辑。
