you are a fool

你是个傻瓜

你是个笨蛋

例句：

If you don’t realize that your expensive, worthless mutual fund is costing you tens of thousands of dollars over your lifetime, you are a fool.

如果你没有意识到昂贵而无用的互助基金在你的余生会花费数万美元，你就太傻了；

I'm not interested in your age, what I want to know is that if you will run after love and dream in your heart and adventure in your life without fear, even if everyone think you are a fool.

我对你的年龄不感兴趣，我想知道你是否会疯狂地追求心中的爱、梦想和生活中的惊险刺激，即使众人当你是傻子也无所畏惧。

希望能帮助到你，望采纳！！！！
