_______ and out of breath, we reached the top of the mountains and stopped ________ the beautiful scenery.
A. Tiring; to admire B. Tiring; admiring C. Tired; admiring D. Tired;to admire
【答案】D
【解析】
【详解】考查形容词用法和固定词组。句意：累的上气不接下气，我们到达山顶停下来欣赏美丽的风景。第一空 tiring 表示“让人累的”，物做主语，tired 表示“累的”，人做主语。第一空其逻辑主语是 we ，故用 tired。 固定词组 stop to do sth 表示“停下来做另外一件事情”，stop doing sth 表示“停止做某事”。这里指我们到达山顶之后停止爬山去欣赏风景，用 stop to do sth。故选D项。
