5. 表示让步

13) Francis Preston Blair, Jr., __________ born in Kentucky, lived and practiced law in issouri.

[A] was

[B] he was

[C] although

[D] who he was

解析：C为正确答案。

6. 表示结果

14) _____________ in all parts of the state, pines are the most common trees in Georgia.

[A] Found

[B] Finding them

[C] To find them

[D] They are found

解析：正确答案为A。本句的主语为pines(松树) ，这样就排除了B 选项，因为-ING分词表主动，而“松树”不可能是“找”(find)这个动作的逻辑主语，即动作发出者。故只有A“found”(被发现) 的逻辑主语与“pines”一致，应选A。
