The happiest are not those who _____ all the best things, but those who can appreciate the beauty of life ______.
A. owns, on their own
B. own, with their own hearts
C. own, of their own
D. own, by their own hearts
【答案】D
【解析】句意：最幸福的人不是拥有一切最好的东西的人，而是那些能用自己的心去欣赏生命之美的人。
own拥有，这里是定语从句，先行词是those，复数，这里是一般现在时态，谓语动词用原形，排除A。短语by one’s own hearts表示通过自己的心。根据题意，故选D。
