核心句型：
He has been left holding the bag.
他一个人背下了黑锅。
left holding the bag 是相当古老的习惯用语，从1760年起就流传了，但没有确切出典，有一种猜测是这里的bag可能是装赃款赃物的袋子，同伙听到了警报都走了，就剩拿着袋子的那个人被抓，人赃俱获。现在这个短语的意思是：“替别人背黑锅，或独自承担错误和罪责”。因此，当美国人说"He has been left holding the bag."时，他/她要表达的意思就是:"He has been made into a scapegoat."、"He has been unjustly blamed."、"He has been left to take full responsibility."。
