Do you know why the train_____ _____?请问是填was late 还是 is late?3Q
1.Do you know why the train_____ _____?请问是填was late 还是 is late?
2.I didn't know______he was waiting for.是填 who that whom
3.He asked______________________________.
A which picture John's was.B which picutre was Joan's

答案

1.was late 是对的.因为,说这句话时,火车迟到的动作已经过去；2,who和whom都可以.这是宾语从句,引导词表示人,且做宾语,故既可以用who（who也可以做宾语）,也可以用whom；但不能用that,因为that在宾语从句里是不充当...
