这两题异曲工但为什么答案不一样

Answer 1

Alice, why didn’t you come here yesterday?
I (did), but my son suddenly fell ill and I had to take him to the hospital.
Alice 有去到那里, 可是突然儿子病了,所以Alice得送他儿子去医院而离开那个地方.答案用did因为alice 已经去了那个地方.
Alice why didn’t you come yesterday?”
“I（was going to),but U had an unexpected visitor.”
Alice 的回答是说,他本来想过去了,可是跟alice 对话的那个人有不束之客.答案用was going to 因为alice 本来想过去,可是还没有过去,对方已经有客人了.所以alice 没有过去,所以就不能用did.
