"I guess they don't see men of his size outside of circuses,"commented the contractor.""We can pretty nearly, though not quite match him, down in Peru though, Tom. Some of the Indians are big fellows.",画横线的句子，两个Though,还有pretty nearly,看不明白。恳请老师们帮我分析一下，谢谢。

文中Tom有个保镖，非常高大，大大超出正常人，这段对话是contractor和Tom一起出国到Peru后的对话，谈论的是这个保镖。
