一道旧题 找出n种答案 狂翻未见讨论 求教

Q17:

Several financial officers of the company spoke on condition that they not be named in the press reports.

1. that they not be named
2. that their names will not be used
3. that their names are not used
4. of not having their names
5. of not naming them

到底选什么啊？ 诚心请教NN   被郁闷了

在GWD和大全都有出现

A和C两种不同的意见 我觉得从不同角度好像是也都有道理 （本人语法很不N的说）

请教大牛

选A

C 中的are not named 与主句时态矛盾。

on condition that ...根据需要可以用动原表虚拟语气、一般现在时、一般过去时。本题的主句时态决定了答案。

支持A
