在英语中，“need sb doing sth” 是一种较为特殊的结构，表示“需要某人持续做某事”或“容忍/允许某人做某事（常用于否定或疑问）”。它不同于常见的 “need to do” 或 “need sb to do sth”。
例句： I can’t stand him leaving the door open.
（我受不了他总是让门开着。→ 隐含“need”的否定用法：I don’t need him leaving the door open.）
✅ Do we need her constantly interrupting the meeting?
✅ I don’t need you reminding me of my mistakes.
⚠️ We need him working on this project full-time. （较正式）
1. need sb to do sth：表示“需要某人去做某事”（一次性或具体动作）。

2. need doing sth（= need to be done）：表示“某事需要被做”。
→ The car needs washing. (= needs to be washed)
3. need sb doing sth：强调“某人持续/反复做某事”的状态，常带负面情绪。
