I anguage can be defincd as tool by which beings ___ with one another.
A communication B. communicate C. communicating D. communicable
网友的句子,抄写得“丢三落四”的,应该是这个样子:
Language can be defined as a tool by which human beings (communicate) with one another.
by which 引导定语从句,定语从句的主语后面需要谓语动词。四个答案中只有communicate 是动词(一般现在时,复数的主语需要原形动词)。communicate with one another:相互交流。
