质疑别人的英语长句怎么说

如果你想表达质疑别人的英语长句，你可以使用以下表达方式：

"I'm not sure I understand what you're trying to say with that long sentence."
"Can you please clarify your point with a shorter sentence?"
"I'm having trouble following your train of thought with that complex sentence."
"Could you break that down into simpler language for me?"

这些表达方式都是礼貌地质疑别人的长句，同时也表明你希望他们能够用更简单的语言来表达自己的意思。
