问题描述:

They were ----busy -----with each other----the time Atoo,to walk B too,taiking.to forget

A. too, to walk

B

too busy to do sth 太忙以至于不能做.
按这个短语搭配及其意思, A和B都不对.
A they were too busy to walk with each other,句子已经完整了,后面the time不好加了
B they were too busy talkingg with each other to forget the time, 语法上没有问题, 但是语义上不合逻辑.他们都忙于互相交谈而不能忘记了时间.要是改成 to remember可以

B
busy doing sth 忙于做某
他们忙着聊天以至于忘记了时间
