Question Words as Non-Questions: 谁都, 什么都
疑问词 + 都 = 泛指肯定（”每个/什么都”） 疑问词 + 也 = 泛指否定（配合否定动词）
| 疑问词 | 都（肯定） | 也（否定） |
|--------|-----------|----------|
| 谁 | 谁都知道 (everyone knows) | 谁也不知道 (no one knows) |
| 什么 | 什么都有 (has everything) | 什么也没有 (has nothing) |
| 哪里 | 哪里都去过 (been everywhere) | 哪里也不去 (go nowhere) |
| 怎么 | 怎么都行 (any way is fine) | 怎么也不懂 (can't understand no matter what) |
关键规则： 否定句用 也，肯定句用 都。两者不能互换。
