问题补充：

After five hours’ drive, they reached they thought was the place they’d been dreaming of.

A. that

B. where

C. which

D. what

答案：

A. that

B. where

C. which

D. what

解析：主要测试宾语从句。分析句子结构可知句中动词reach需要宾语，另外句子was the place they’d been dreaming of需要主语，还有既是句中they thought应该考虑成插入语，至此可知选择what最佳。译文：五个小时的驾驶后，他们以为他们到达了他们一直梦想的地方。
