在英语中，despite 和 although 都可以用来表达“尽管”、“虽然”的意思，但它们在语法结构和使用方式上有明显区别。
1. 词性和结构不同
Although 是一个从属连词（subordinating conjunction），后面接一个完整的句子（主语 + 谓语）：
Although it was raining, we went for a walk.Although she studied hard, she didn’t pass the exam.
Despite 是一个介词（preposition），后面只能接名词、代词或动名词（即不能接完整句子）：
Despite the rain, we went for a walk.Despite studying hard, she didn’t pass the exam.
2. 可互换的情况
当 although 引导的从句可以简化为名词短语时，两者在意义上可以互换，但结构必须调整：
Although he was tired, he kept working.→Despite his tiredness, he kept working.或更自然地说：Despite being tired, he kept working.
3. 常见错误
❌ 错误：使用 despite 后直接跟完整句子
Despite it was cold, we swam.（错误！）
✅ 正确改法：
Although it was cold, we swam.Despite the cold, we swam.Despite it being cold, we swam.（较正式）
4. 小结
| 词 | 词性 | 后接内容 |
|---|---|---|
although |
连词 | 完整句子（主语 + 动词） |
despite |
介词 | 名词 / 代词 / 动名词 |
记住这个口诀：“Although 接句子，Despite 接名词。”
