【though的用法】“Though”是一个常见的连词，常用于引导让步状语从句，表示“虽然……但是……”的意思。它在英语中具有较强的灵活性，既可以放在句首，也可以放在句尾，甚至可以和“as”、“although”等词互换使用。掌握“though”的正确用法，有助于提升语言表达的准确性和地道性。
一、基本用法总结
| 类型 | 用法说明 | 例句 |
| 引导让步状语从句 | 表示“虽然……但是……”，通常与主句形成对比 | Though it was raining, we went out. |
| 放在句尾 | 用于强调让步，语气更口语化 | We went out, though it was raining. |
| 和“as”互换 | “though”和“as”都可以引导让步从句，但“as”更正式 | Though/As he is tired, he continued working. |
| 与“but”不能同时使用 | “though”本身已含让步意义，不能与“but”连用 | ❌ Though he is rich, but he is unhappy. ✅ Though he is rich, he is unhappy. |
二、常见搭配与结构

三、与其他让步连词的比较

| as | 语气比“though”更正式，常用于倒装结构 | As a student, she works hard. |
