Many gases in the atmosphere actually heat energy that escapes from the Earth’s surface back to the earth.

A．finding; reflecting	B．found; reflected
C．found; to reflect	D．found; reflect

答案

解析

考察非谓语动词。过去分词做定语表示被动的，发生过的动作。句意：在空气中许多被发现的气体实际上反映了从地球表面扩散又回到地球的热能。前文动词为gases的定语，发生过的用过去分词，下文从此为句子谓语。叙述一个客观存在的事实，用一般现在时态，gases为复数，故动词用原形，选D。
