whether与if的区别
很多考生容易混淆whether和if，但两者在正式写作中有明显区别：
| 对比项 | whether | if |
|---|---|---|
| 正式程度 | 更正式，适合学术写作 | 较口语化，多用于条件句 |
| 引导宾语从句 | 可用于所有动词后 | 仅用于某些动词后（如ask, know） |
| 与or not连用 | 可单独使用或加or not | 必须加or not才能表示“是否” |
| 介词后使用 | 可用（e.g. It depends on whether…） | 不可用 |
例句对比：
- 正式写作：The report examines whether the policy is effective. （√）
- 非正式语境：I wonder if the policy works. （√）
- 错误用法：The study focuses on if the method is reliable. （×）
