Question

【题目】______ opinions on the schedule, we finally reached on agreement.

A． Having exchanged B． Exchanging

C． Exchanged D． To exchange

Answer 1

【答案】A

【解析】根据主句谓语达成（“reach”）发生在非谓语从句谓语交换(“exchange”)以后，非谓语从句的谓语应该用完成形式。非谓语从句的逻辑主语是主句主语我们（“we”），和谓语交换“exchange”构成主动关系，因此用ing的主动完成形式，选A。句意：对日程交换看法以后，我们终于达成了协议。
