以下是查字典为大家整理的关于商务英语口语：询问例证的文章，供大家学习参考！
要求举例左证
1. Can you back ... Up?
2. Can you give us an example?
3. Can you provide any example to prove what you’re saying?
4. Can you give any example that show you’re right?
back在此作动词，为"支持"之意；back up有"支援；救援"的意思，用于此句型，解释为"以例子或事实证明自己所说的话"。这种句型十分有礼客气，语气虽含有稍许的怀疑却也直接坦率。
表达己见
1. As I see it, first of all...; second...
2. It seems to me that, one, ...; two, ...
3. I’m inclined to think that, one, ...; two, ...
4. The way I see it is that, one, ...; two, ...
as I see it 这个口语是"以我所见；就我看来"的意思；see 则指"看待"；first of all是"首先"之意，具有强调的作用。整个词组的意思是’我的看法是，第一……；第二……，其后直接接自己的意见及想法。
