Unit3语法讲解及习题：并列复合句（and_but_so）-2025-2026学年沪教版英语（五四学制）七年级下学期

沪教英语（五四学制）七下Unit3语法讲解及习题 并列复合句（and/but/so） 一、语法知识点详解 1. 定义与功能 并列复合句由两个或多个独立的简单句，通过并列连词 and、but、so 连接而成，用来表达完整的逻辑关系。这与本单元“互助帮助”的主题紧密相关，可用于描述事件的承接、转折与因果。 2. 核心连词用法 连词 功能 例句 and 连接两个并列或递进的观点，表示“和、并且” Mrs Bell's face turned pale, and she broke out in a cold sweat. but 连接两个转折或相反的观点，表示“但是、然而” Tom was shocked, but the eleven-year-old boy took a few deep breaths to calm himself down. so 连接两个因果关系的句子，表示“所以、因此” Mrs Bell lived alone, so there was nobody around. 3. 标点规则 当 and、but、so 连接两个完整的句子时，需要在连词前加逗号。 例：I wanted to call you, but I didn't have your phone number. 如果连接的是两个短语，而非完整句子，则不需要逗号。 例：I like apples and bananas. 4. 逻辑关系辨析 and：表示顺承、递进或并列，前后内容方向一致。 but：表示转折，前后内容方向相反或相对。 so：表示因果，前面是原因，后面是结果。 二、练习题 用 and, but 或 so 填空 1.
