If you start over or start something over, you begin something again from the beginning.表示从头再来。来看两个例句：We decided to abandon the first draft of the report and start over.我们决定放弃报告的初稿，从头再来。Sometimes I feel like moving out to the coast and starting over.有时我想搬到海边，从头再来。
在美剧《马男波杰克》中，马男批评戴安时，就用到了这个表达：Oh, I don't think you understand what's happening here. This is not a casual conversation between friends. This is your boss telling his employee that she did a bad job. Start over, but do it right this time.我觉得你似乎没有意识到这件事的严重性。我并不是作为朋友在跟你轻松地聊天，这是一位老板在对员工说，你的工作做得很烂。从头再来，这次一定要写好。
② back to one
重新回到了一，也就是“从头再来”。在美剧《破产姐妹》中，好莱坞找到Max拍戏，导演在喊话时就用到了这个表达：Come on, everybody. Back to one. And action! Max, you're wiping the counter. The killer comes in. You look up…好了，各位，重新开始。开拍。麦克斯，你在擦桌子，杀手走了进来。你抬头看……
③ take it from the top
这个表达也可以表示“从头再来”，top 就是“顶部”，从顶部开始当然就是“从头开始”啦。在美剧《摩登家庭》中，Cameron让孩子们开始排练时，也用到了这个表达：Okay, okay! Break's over, everyone! Let's take it from the top. Listen, we're running 20 minutes long, So we're gonna go ahead and cut the Bollywood number.好了好了，休息结束了，大家伙儿。让我们从头再来一遍。听着，因为演出时间是20分钟，所以我们要去掉宝莱坞部分继续演。
