It was a【C1】______ project, easily surpassing the scale of such previous human【C2】______ as the Panama Canal.

【C6】
选项 A、merges
B、connects
C、relays
D、unifies
答案B
解析 动词辨义。句中的破折号表示解释说明，指出信息高速公路实际上是电子网络，而网络的基本功能就是连接，而且空格后是由多个名词组成的宾语，所以选择B项connects“连接，联合”。A项merges意为“合并”，C项relays意为“接替，转播”，D项unifies意为“统一，使一致”。这三个动词都没有“连接”的意思，故均可以排除。
