A. to communicate, have

B. communicate; having

C. communicating; to have

D. communicated; to have

答案：

A. to communicate, have

B. communicate; having

(答案→)C. communicating; to have

D. communicated; to have

解析：考查非谓语动词，第一空填communicating; 做宾语补足语，因为communicate和people是主动关系，第二空填 to have做主语，前面的it是形式主语，句型是：It is+adj+to do，句意是：每天有越来越多的人用英语交流，我们知道掌握英语越来越重要了。选C。
