I wonder if you would like to start with matters of principle or specific issues?

让我先谈一个问题。

If you agree(With your permission), let me start with one issue

在谈那个问题之前我想对您刚才讲的话谈点看法。

Before we trun to that issue, I wish to make a few comments/remarks on your presentation.

您对此事怎么看呢？

I wish to benefit from your views on this matter./ What is your view on this matter?/ How do you see this matter?

我提议休会十分钟。

I will pick up where we left off just now.

对不起，我插一句。

Sorry for the interruption but

当然可以！

By all means.

怎么都行！

Whatever you say.

我没有异议。

I have no objection.

我方对这个问题有异议。
