Question

E-mail, as well as telephones, ____________ an important part in daily communication.

A．are playing

B．have played

C．is playing

D．play

Answer 1

C

试题分析：考查主谓一致：当主语被as well as连接的时候，谓语和前面的主语一致，这句话就是和E-mail一致，用单数，几个选项只有C是单数，句意：电子邮件和电话在日常生活中起着重要的作用。选C。
点评：主谓一致的考点较多，要在理解的基础上加以记忆，多练习加以巩固。这里考查的是如果主语被as well as，together with，with，but，except，including等词连接的时候，谓语要和前面的主语一致。
