Question

英语单选题,
1.I ____in Beijing for some time and then I went to Shanghai for an important meeting.
a.stay
b.had stayed
c.have stayed
d.stayed
选哪个为什么..
What were u doing when tony phoned
I had just finished my homework and_____to take a shower.
为什么这里填was starting而不填started?
最后一题
WHose exam paper is it?
It __be Lucy's,She always forgets to write her name on it.
这里答案是must
为什么may不行?
她总是忘记可是也不代表绝对是她的啊.应该是她的不行吗?
越易懂具体越好.
第一题的答案其实是D。
(我没写错!)
我选了c的,问老师她讲得迷迷糊糊,b对于这个问题又如何?b是我自己加的行不行不知道.
有没有英语老师给讲解一下?好的分再加!

Answer 1

1 c 现在完成时态,“I have stayed in Beijing...”
2 关于语境问题.答案关键在于 B 给的答复的后面那句.“She always forgets to write her name on it.” 这样的话,那么说明她说是lucy的就不是猜测 还是有根据的.所以选must.如果没有这一句的话 ,那两个都可以.
