and out of breath, we reached the top of the mountain and stopped the beautiful scenery.

网友回答

A. Tiring, to admire
B. Being tired, admiring
(答案→)C. Tired, to admire
D. Tired, admiring
解析：考查形容词用法和固定词组。固定词组stop to do sth停下来做另外一件事情；stop doing sth停止做某事；第一空的形容词是对句子的主语情况进行的说明。句意：很累而且上气不接下气，我们到达了山顶，停下来欣赏美丽的风景。故C正确。
