E-mail, as well as telephones, ______ an important part in daily communication.
A.is playingB.have playedC.are playing D.play

答案
A
解析

试题分析:考查主谓一致:主语是as well as连接的时候,谓语和前面的主语一致,就是和E-mail一致,用单数,四个选项只有A是单数谓语,句意:电子邮件和电话一样在日常交流中起着重要的作用。选A。
点评:在英语中,句子的主语和谓语动词要保持数上的一致关系,叫主谓一致。这种关系通常要遵循下面三条原则:1.语法一致原则。句子的主语是单数形式,谓语动词要用单数形式;主语是复数形式,谓语动词用复数形式2.意义一致原则即谓语动词该用单数还是复数取决于主语所表达的内容在含义是单数意义还是复数意义。3.邻近原则谓语动词该用单数还是复数形式,取决于最邻近它的名词、代词或其它词的数。
