With the development of modern society, E-mail as well as telephones         an important part in daily communication.

A．have played

B．is playing

C．are playing

D．played

答案

B

解析

试题分析：考查主谓一致和时态：两个主语被as well as连接时，谓语和前面的主语一致，就是和E-mail一致，根据句意：随着现代社会的发展电子邮件和电话在日常生活中起着重要的作用。用一般过去式。选B。
点评：主语为单数名词或代词，尽管后面跟有with， together with， except， but， like， as well as， rather than， more than， no less than， besides， including等引起的短语，谓语动词仍用单数形式；若主语为复数，谓语用复数形式。时态题根据句子的时间判断。
