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

A.        that they not be named
B.        that their names will not be used
C.        that their names are not used
D.        of not having their names
E.        of not naming them
划线部分是"that they not be named"

我做gwd，答案是A，我看有人说是on condition that 引导虚拟语气后面be用原型，有没有这一说法？而且我看到有很多例句都是像这样的on condition that he is。。。。。表示不明白
2，on condition of 有这一用法吗？
3有人说选c，不知道该如何是好

on condition that之后是引导虚拟语气的。所以要用动词原形。

C选项除开没用虚拟语气之外。。貌似名词形式没有动词好。ETS更倾向使用动词，因为动词能更清晰表达句子。
