为什么用 "at"？​

He was so surprised at being discovered

  1. 固定搭配：
    在英语中，"surprised" 通常与 "at" 搭配，表示 "对某事感到惊讶"。类似的表达还有：

    • surprised at + 名词/动名词（如：surprised at the news / surprised at seeing him）
    • surprised by（也可用，但更强调被动，如：I was surprised by his reaction.）

  2. 语法结构：

    • "being discovered" 是动名词（gerund），表示 "被发现" 这个动作。
    • "at" 在这里连接 "surprised" 和 "being discovered"，表明惊讶的原因。

对比其他介词：​

  • "surprised by" → 更强调被动，常用于具体事件（如：I was surprised by the loud noise.）
  • "surprised at" → 更常用于抽象概念或行为（如：She was surprised at his rudeness.）

例句：​

✅ He was surprised at being discovered.（他对被发现感到惊讶。）
✅ She was surprised at his honesty.（她对他的诚实感到惊讶。）
✅ They were surprised by the sudden rain.（他们对突然下雨感到惊讶。）

所以，"at" 在这里是符合习惯用法的正确选择，使句子更自然流畅。
