问题描述:

The meeting _____when Mr.Wang _____to school.A has begun; get B has been on; get C had begun; got
为什么选C,不能够选D呢,还有,整个句子发生在现在不行么,从哪看出来一定是发生在过去的?
D.D had been on; got

d你没写呀,
你想啊王先生到了会已经开始了,那会肯定是在王先生来之前就开始了,如果王先生来是用过去式,那会开始肯定是用过去完成时了(过去的过去用过去完成时)
d中的had been on 表示会议开始的状态,常与时间段用在一块,而此句中王先生来是表示一个时间点,所以不能用
