不但不/不但没有⋯⋯，反而⋯⋯ Grammar Structure

The structure "不但不/不但没有⋯⋯，反而⋯⋯" is used in Chinese to express a contrast between two statements, where the second statement contradicts or negates the expectation set by the first.

• 不但不 (bù dàn bù) translates to "not only does not" or "not only does he/she not," indicating that the subject fails to perform an expected action.
• 不但没有 (bù dàn méi yǒu) translates to "not only does not have," similarly indicating a lack of something that might be anticipated.
• 反而 (fǎn ér) means "on the contrary" or "instead," introducing a surprising or opposite outcome.

This structure is often used to highlight disappointment or an unexpected result.

Examples:

1. 他不但不帮我，反而还给我添麻烦。
   (He not only does not help me, but instead adds to my troubles.)

2. 夏天过去了，天气不但没有凉快，反而更热了。
   (Summer has passed, and the weather not only did not cool down, but instead became even hotter.)

3. 他不但没有鼓励我，反而还批评了我一顿。
   (He not only did not encourage me, but instead criticized me.)

In each example, the first part sets an expectation that is then contradicted by the second part, emphasizing the unexpected nature of the situation. This structure is effective for conveying irony or disappointment in various contexts.
