The Whites ///that we//the Summer Palace but we didn’t have enough time then.
A has hoped,will visit
B was thinking /would visit
C had thought would visit
D has planned ,has visited
选什么为什么？
补充网友答案的解析：答案c，因为but we didn’t have enough time then.这是一般过去时，表示已经过去。
这句话;怀特一家人希望我们去参观颐和园，但是当时我们没有时间去。
肯定是我们去之前，怀特一家人就说过这类话。因此，”过去的过去“即用“had——过去分词”，也就是过去完成时。

The Whites had thought that we would visit the Summer Palace but we didn’t have enough time then.
答案 是 C had thought ,would visit
根据后句 判断 句子是过去时 排除 AD
第一句主句谓语 发生 在 第二句 谓语 之前 所以用过去完成时 排除B
所以 答案是C
