Olympic Games ：是“固定词组” 奥林匹克运动会
不成以说 an Olympic Gam。
但能够说：the Olympics
而，Olympic：是指：奥林匹克的一项竞赛。
After 7 years of preparations, the Summer Olympic Games were held in China for the first time.
Today we tell about the Winter Olympic Games that open February twelfth in Vancouver, Canada.
As you know, the Olympic Games are alleged to have started in 776.
各人晓得,奥运会据称始于公元前776年
从以上例句知， Olympic Games 是复数（包罗有许多体育项目标综合性赛事），故不消an Olympic Games 。
是复数，如例：The Olympic Games have been held each four years.故不克不及说an Olympic Games。
