The same thing happened to him _____ to me .
A.as it did B like it did C as it had D like it had
答案说选A,可我觉得选C.发生在我身上的事不是应该发生在他前面吗?

答案是A。这句话可以采用补充完整的方式去做，原句完整的表达是：
The same thing happened to him as it happened to me.其实需要找一个能代替happened的一个单词，由于happened是过去式，因此用did.
这是一个对应关系的考察。如果这句话是这样的：the same thing had happened to him __ to me.的话，那么就如同你说的，应该选C。英语语言的逻辑同汉语不太一样。窃以为这类的题考的都是一种表面上的对应替代关系，不要在汉语意义上深究。
