英语语法问题,关于过去对现在的影响
I had been working on math for the whole afternoon and the number (swam) before my eyes.
Alvin,are you coming with us?I'd love to.But something unexpected (has come up)
同为过去对现在的影响,请问两句句子分别采用的用法为什么不同,第一句比较理解,因为过去完成进行时老师讲的细,第二句没有什么时间上的词,为什么用现在完成时?

第一句是过去完成时,第二句是现在完成时.过去完成时则比现在完成时往前推了一段时间,即"过去的过去''. 是站在过去的时间点上.现在完成时是指某个动作从过去开始一直持续到现在,或对现在有影响.
第二句的意思是“之前意料不到的事情现在发生了”,对现在产生了影响.
