45.Which of the following sentences is WRONG?
A.Although it was very late,Miss Liu didn’t stop working.
B.The plane has already taken off when we got to the airport.
C.We should not only help each other but also learn from each other.
D.Mum is sleeping now.Please tell them not to make so much noise.
答案:B
正确句子:The plane (had) already taken off when we got to the airport.
注释:句子前后时态要一致,后面是"got to"过去式,那前面应该用过去完成时而不是现在完成时,所以应把"has"改为"had"
