✅ 正确答案：是的！
短语 “attach importance to” 中的 “to” 是介词，不是不定式符号。因此，它后面必须接 名词、代词或动名词（即 doing 形式）。
✅ We attach great importance to protecting the environment.
✅ She attaches importance to being punctual.
✅ They don’t attach much importance to winning.
✅ She attaches importance to being punctual.
✅ They don’t attach much importance to winning.
🔍 为什么是 doing？
很多学习者误以为 “to” 后面要接动词原形（如 to do），但这里的 “to” 是介词，和 look forward to、be used to 等结构一样，后面需接名词性成分。
- attach importance to + 名词：attach importance to education
- attach importance to + 代词：attach importance to it
- attach importance to + 动名词：attach importance to learning English
❌ 常见错误
以下用法是错误的：
❌ He attaches importance to protect the forest.
❌ We should attach importance to do our homework.
❌ We should attach importance to do our homework.
错误原因：把介词 “to” 当成了不定式符号。
📚 类似结构对比
英语中还有多个含介词 “to” 的短语，同样后接 doing：
- look forward to doing（期待做某事）
- be used to doing（习惯于做某事）
- object to doing（反对做某事）
- devote oneself to doing（致力于做某事）
记住：只要 “to” 是介词，后面就不能接动词原形！
