(C) one of the only eight undeveloped Revolutionary War battlefields that remains

(D) only one of eight Revolutionary War battlefields to remain undeveloped（A）

Q1：请问大家上面A的remain是不是因为that修饰battlefields所以后面remain要用复数形式作battlefields的谓语？跟下面的用法一样？

Q2：上面A的had remained 改成remianed可以吗？哪里可以看出要用过去完成时啊？

谢谢大家！

remain 修饰battlefields, 因为前面的approve 发生在1989. 而remain的动作在这之前,所以用过去完成时.

379题. that从句修饰fields所以surround 用复数,最后一句为同位语结构,不是句子,所以不能用who, who必须引导句子
