你真让我失望英语

You really let me down! 因为这样说最符合美国人或英国人的说话习惯,而disappoint一般用于书面语,做及物动词,后接人, sb. disappoint sb. 再按照情况选择时态和语态

You let me down.let sb. down 让某人失望至于LZ那个disappointed和disappointing 区别如下:当主语为人时 disappoint 用 disappointed.当主语为物时 disappoint 用 disappointing.当修释词为adv.(副词)时disappoint(至于为什么adv.修释v.(动词)原因就不解了 国际规定我也没法)

或者是：You depressed me(你太让我失望了）和asshole【冒犯性语言】慎用！（混蛋！）

I am so disappointed at you !Your deportment disappointed me!I was very disappointed of you !

you are disappointed for me true。

You got me so disspointed!!告诉我，我刚被我男朋友踹了，真他妈的要命啊！！。。。都给他翻译出来。

you made me disappointed very much!disappointed 在这里是形容词 失望的 而disappoint 是动词 当然你也可以说 you disappoint me so much那这里的disappointed 就是动词的过去式了

You really let me down.You disappointed me a lot.
