The olympic Games,to be first played in 776 B.C.,did not include wormen players until 1912
这是改错题,to be first played错了,答案是改为first played,请问答案为什么把be也去掉了呢?感觉去掉就说不通啊,为什么,难道是因是定语从句的原因?

played是过去分词,本身就可以表示“被动”和”动作已经完成“这两层意思.是非谓语动词.如果加上be,就只能作谓语了.而这句话的谓语是did not include.一个句子只能有一个谓语,其余的都是非谓语动词.
那么为什么to be played要be动词呢?这是因为to 后面要接动词原形,不能接过去分词.
祝你学习进步,更上一层楼! (*^__^*)
不明白的再问哟,请及时采纳,多谢!

to 不定式常指将来动作
这里是过去动作，相当于定语从句whic was first played in 776 B.C.,
