问题补充：

and short of breath, Andy and Ruby were the first to reach the top of Mount Tai.

A. To be tried

B. Tired

C. Tiring

D. Being tired

答案：

A. To be tried

(答案→)B. Tired

C. Tiring

D. Being tired

解析：该句的意思是：尽管累并且喘不过来气，但是Andy and Ruby是最早到达泰山山顶的人。形容词可以作状语表示伴随，原因或让步等关系。在该题中形容词作状语是表示让步的，可以恢复为though they were tired and short of breath，然后在进行省略。该题容易误选D。要注意的是形容词作状语时其前不能加being。
