奥林匹克运动会是the Olympic Games，与the Olympics同义作主语时，谓语动词用单数或复数均可。如：The Olympic Games is/are held every four years in a different country。

一、语法一致原则

1. 单数主语即使后面带有with, along with, together with, like, but, except, besides, as well as, no less than, ra...

二、the Olympic Games作主语时

其实，the Olympic games 作主语时，谓语动词用单数或复数都可以的（只不过在现代英语中用复数比较普通。

三、实例说明

1. The Olympic Games are held every four years. 奥运会每四年举办...2. The Olympic Games is going to be held in Beijing in 2008.

单数，特指奥运会，games是固定用法。

四、

如果是泛指“奥运会”，用复数；而具体到哪一届就应该用单数了。例如：The Olympic Games are held every four years. The 29th Olympic Games is going to be held in Beijing in 2008。
