[视频] 跟冠希学英语：reinvent the wheel

✏️笔记：1）reinvent the wheel：重新发明轮子，比喻“重复劳动、炒冷饭、拾人牙慧”（陈冠希这里用这个短语属于“反语”）2）造句：①We don't need to reinvent the wheel; we just need to hire someone who already knows how to do it.我们不需要重复劳动了，我们只需雇一个懂行的人即可。②Sometimes, reinventing the wheel can also be a kind of innovation. 有时候，炒冷饭或许也是一种创新。
