Could you do me a favor?or Can you do me a favor
有助于回答者给出准确的答案

could you..这是表示请求的说法...
更委婉的表达还有:I'm wondering if you could do me a favor...
但是要注意见什么人说什么话..和朋友太客气会让人觉得不舒服...
和很熟悉的人说Please...或者give me a hand...也就差不多了...甚至直接说Open the door...也行...
当然,客气表达还有特殊效果,比如I'm wondering if you could please keep quiet when I am speaking.(能不能肯请你在我说话的时候保持安静)..
