"不能记住过去的人注定会重蹈覆辙。"

Simplified Meaning:

When people don't learn from what happened before, they might make the same mistakes again. Think of it like touching a hot stove. If you don't remember how it burned your hand last time, you might touch it again and get burned once more. For instance, in history, if we forget about the problems caused by major wars, like World War II, we might allow similar things to happen again. This is why it's important to study history in school, so we can understand what went wrong and avoid making the same choices. In everyday life, if you don’t remember how staying up too late before a big test made you tired and perform poorly, you might repeat that mistake and get another bad grade. Remembering the past helps us make better decisions and avoid unnecessary problems in our future.
