这是老布什逝世后经济学人一篇关于老布什的文章中的一句话，但原句被传的走样了。原句如下：

His forte, and first love, was foreign policy. He had been ambassador to the UN for Nixon, an envoy to China for Gerald Ford (he and Barbara riding round delightedly on bicycles) and head of the CIA, besides, as vice-president, a follower-of-the-hearse at dozens of state funerals. 

这里，his forte 和 first love指的是同一件事。所以谓语动词用单数 is .

又如，一个企业老总的秘书，同时又是他的情人，一个人二个身份，就可以用and 连接，谓语动词仍用单数。

His secretary and lover has cheated him.
