推倒重来用英文怎么说

"Start over from scratch" 是一个常用的表达，意思是从头开始，一切重新开始。这个短语的来源可能源自于制作产品或建筑物时，需要从零开始构建的过程。

例句：

"After the company went bankrupt, we had to start over from scratch."（公司破产后，我们不得不从头开始。）
"The project was a failure, so we had to start over from scratch."（这个项目失败了，所以我们不得不从头开始。）
"I lost all my notes for my presentation, so I had to start over from scratch."（我把演讲笔记都弄丢了，所以我不得不从头开始。）
