agree通常与介词with，on, about 搭配。但也可以后接介词for, 表示同意的是哪一部分，即并不是完全同意，只是部分同意。例如下列COCA例句所示：

I think Senator McCain and I agree for the most part on these issues. 

I agree for the most part with her conservative views. 

In fact I would be tempted to even agree for higher taxes for more than 75k income families if we are allowed to do some massive stimulus works.

I agree for actual printed works.

I agree for what you said, we must focus in our present not in the pass.

We will not agree for their entry into the WTO unless it's under commercially meaningful terms. 

网友这个句子中：

Let's carry on with what we agreed for now.

what为介词for的宾语。

现在让我们继续我们先前已经达成一致的事项。
