商务谈判中怎么回避明确地答复

I'm afraid I can't give you a definite reply now.

也许现在我没法让你一个确立的回应。

I can't make a decision right now.

现在我没法作出决定。

I just need some time to think it over.

我需要時间考虑一下。

We are still a little unsure about the prospect, though.

但是，大家针对市场前景還是有点儿不可以明确。

There are certain points that I'll have to consider very carefully.

一些难题我得深思熟虑。

That may well be so. I'm not sure.

很可能是那样的。我不敢明确。

It all depends.

这得看情况而定。
