英语学习笔记📝 🔑 核心知识点：because 和 because of 的区别与用法 一、核心区别（最关键考点） because +从句 从句有主语+谓语（完整句子） because of +名词/代词/名词短语 （无主谓结构，仅为名词性成分 ） 二、典型错误与修正 1. ❌ 错误：I was worried because of Mary was late. ✅ 修正：I was worried because Mary was late. （原因：Mary was late 是完整从句，需用连词 because） 译文：我感到担心，因为玛丽很晚还没来。 2. ❌ 错误：She was late because the traffic. ✅ 修正：She was late because of the traffic. （原因：the traffic 是名词短语，需用介词短语 because of） 译文：因为交通的缘故，她来晚了。 三、补充用法与例句 1. because（连词） ◦ 可用于回答 why 引导的问句： — Why were you late? — Because I missed the bus. ◦ 可与 not...because... 连用，表“不是因为……”： I didn't go out because it rained.（我没出门是因为下雨了。） 2. because of（介词短语） ◦ 后接代词宾格：She cried because of him.（她因为他哭了。） ◦ 后接动名词短语：He failed because of not studying hard.（他因为不用功学习失败了。）
