"You and I are both wrong" 可以用英文表达为 "We are both mistaken" 或 "We are both wrong."

这个表达是由英语中的主语与谓语构成的。"You and I" 是主语，"are both wrong" 是谓语。

举个例子：

Example: "You thought the movie was at 7pm, but I thought it was at 8pm. Oops, we are both mistaken. It's actually at 9pm."

翻译："你以为电影是在晚上 7 点，但我以为是在晚上 8 点。哎呀，我们俩都错了。实际上是在晚上 9 点。"

Example: "I thought the capital of France was Marseille, but you thought it was Lyon. We are both wrong. The capital of France is actually Paris."

翻译："我以为法国的首都是马赛，但你以为是里昂。我们俩都错了。法国的首都实际上是巴黎。"

希望这个回答能帮到你！
