-Really? How long________each other? Not more than a week,I' m afraid.
A.did they know B.have they known
C.have they got to know D.had they known
2.(★★★★)Glad to see you back. How long________in Russia?
A.did you stay B.have you stayed
C.were you staying D.have you been staying选什么
当用how long提问时，要用现在完成时，表示已经完成的动作。
所以，第一题选B
A 和D 排除
C的时态看上去正确，但have they got 的got应该用过去分词gotten.
第二题，选D
用现在完成进行时
表示某一动作开始于过去某一时间，延续或重复地出现至今，或将继续延续至将来。
1 B 真的吗？他们彼此认识有多长时间了？不会超过一周的，我想。
不要选C，get to know是一个瞬间的动作，用完成时不合适。而且楼上说的gotten也不对，过去分词got就是了。
2 A 很高兴你回来了，你在俄罗斯待了多久？
已知回来了，问在别处住了多久，用一般过去时就可以了。
楼上这位说的很对.
