Dear Mr. Ridge,
It was good of you (147) such kind of Joint Operation and I deeply appreciate it.
However, I feel that I must check a few things out for mutual benefits. The communications technical staffs are evaluating them at this time. I am mapping out plans now (148) and I will let you know what the results will be.
Please let me know (149) the primary technical contact will be in your side.
Thank you again for your proposal.
Yours very truly,
Paul Lee, Marketing Director

A．offering
B．offered
C．offers
D．to offer
答案
D
解析：看到句首的it了吗?如果主语是it，就要考虑是不是形式主语。这里是it…to do／that 的形式，正确答案是D选项。形式主语句不用A选项那样的动名词，而B选项是形容词，后面没有被修饰的名词；C是谓语动词，也是不合适的。
