迷你對話：

那可真令人失望。

B: Yeah. He really does let me down.

是的，他確實讓我失望。

B: I’m at the end of tether. I run out of ideas.

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。

You don't expect him to let you down.

你不希望他拆你的臺。

You can believe in him and he will never let you down.

你可信任他，他決不會使你失望。
