迷你对话A: From what I have said, we can draw a conclusion that the defendant is innocent.

综上所述，我们可以得出结论——被告是无辜的。

你的说法是站不住脚的，你刻意隐瞒了被告人的罪行。

地道表达have a leg to stand on1. 解词释义Have a leg to stand on是美国俚语，字面意思是“有一条可以站得住的脚”，比喻为“（人）理屈词穷，行为无法解释”“（论点等）缺乏事实依据或毫无事实依据而不可成立”。

2. 拓展例句e.g. The truth of the matter was they didn't have a leg to stand on.

事实是，他们的说法儿根本站不住脚。

e.g. He hasn't a leg to stand on for his behavior.

他的行为是完全没有道理的。

e.g. Without written evidence, we don't have a leg to stand on.

没有书面证据, 我们就站不住脚!

e.g. It's only my word against his, I know. So I don't have a leg to stand on.

现在是我和他各说各的，这我知道。所以我的话无法证实。

Ps 1：draw a conclusion的意思是“下结论，做出结论”。例如：

ps 2：From what sb. says的意思是“从某人所说的来看”。例如：
