给看看这题

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

答案是C,但A哪错了？

刚查了词典：on condition that 以。。。为条件。后加动词原型，实际上是省略should的虚拟

例：1。 We agree to rent the house on condition that the roof be fixed.

2. He can swim in the river on condition that he do not go too far from the bank.
