地道表達：

let someone down

解詞釋義：

let someone down與“make somebody disappointed”的意思一樣，都是“使某人失望”。有點場合使用的區別，就是let sb down在口語實用頻率更高。

拓展講解：

let down用連字符將它們組合在一起，就變了名詞let-down。這在對話中的第一句就可以看到。

支持范例：

I don't see that you let him down in any way.

我看這沒有什么對不起人的地方。

Her tense face told me that we had let him down hard.

她緊張的面色告訴我們這次我們可大大地辜負了他了。
