大师,问个英语语法问题!
My girlfriend asked me (how could ) I (know) today （was） her birthday.
括号里的词用的对不对,could 后用原型,was 要不要用原型?这个是个宾语从句?

解答

was应该用原型,因为这是在陈述一个事实,今天的确是她的生日,today 是现在时的时间状语.
句子分析：how引导ask的宾语从句,所以在这里要用陈述语序,how i could know
know后面带了一个省略了引导词that的宾语从句
My girlfriend asked me how i could know (that)today is her birthday.
