When I talked with my grandma on the phone,she sounded weak ,but by the time we___ up ,her voice had been full of life.A,were hanging B,had hung C,happens D,would hang 答案是C,我想知道A为什么不对,我刚打算挂电话,不是很通吗?
不可能是C.happens（意思不对呀）（应该是hung吗）；
by the time引导时间状语从句,在这里were hanging可理解成“要挂电话”,就是将来的意思,跟第四个答案类似.“到了挂电话时（一般过去时表示过去将来的）
By the time he arrives, we will have stayed there, waiting for him.
The boy ____ hot on the forehead ,so he must be sent to hospital at once.
A,is felt B,is feeling C,feels D,has felt 答案是C,为什么不能选B?
这里的feel意思是”摸起来是……“,不是感到的意思.所以,不用进行时态.
I am feeling better.我（此时此刻正）感到好多了.
Late again!Where____?
Sorry ,I ____in the heavy traffic,or I would have been here earlier.
A,were you;have got stuck B,have you been ;have got stuck
C,were you;got stuck D,have you been;got suck
答案是D,为什么A不可以啊,两个空都不太理解.谢谢了
第一个其实你问的是过去,你并不想了解现在的情况.
Where were you?
I was in the school.（现在怎样,不知）
Where have you been?你去哪了?（直到现在,了解现在的情况）
我塞车了（过去的事情）,否则我会更早到（过去相反的假设）
改成虚拟条件句：
If I had not got stuck in the heavy traffic, I would have been here earlier.
再问： 谢谢，可是按您的意思，最后一题不是应该选A吗，答案是D啊？
再答： （分析A错误：问过去情况） Where were you? I was in the school.（现在怎样，不知） 而且A的第二个答案也不对的。 Where have you been?你去哪了？（直到现在，了解现在的情况）（见面想了解过去的状态对现在的影响，也就是现在时态） 我刚才在拥挤的交通中塞车了。（in the heavy traffic：特指刚才的拥挤的交通，所以用got stuck过去的） 答案就是D
