问题：这里有两个itdid，请问第二个为什么要这么用，谢谢Dr.Kin 
Dr. King lid to say that our Civil Rights Act was written in the streets by citizens who marched for the idea that all men are created equal. He was right; yet there is no doubt that the law came as 【it did】 when i【t did】 because of the courage and leadership of Martin Luther Dr. King lid to say that our Civil Rights Act was written in the streets by citizens who marched for the idea that all men are created equal. He was right; yet there is no doubt that the law came as 【it did】 when i【t did】 because of the courage and leadership of Martin Luther King. 
回答：第一个【itdid】是指itdidcome,用于强调,第二个did代替的是 elawcameas【itdid】wheni【tdid】在这个法律出现在了它的的确应该出现的时刻,也就是应用而生的意思.马丁路德金常喜欢说,我们的公民法是由那些为追求人人生来平等这个理想而奋斗的公民们写在大街上的.他说的对.毫无疑问,由于马丁路德金的勇气和领导才能让这部法律应运而生.
