解析
试题分析:句意,随着现代社会的发展,电子邮件和电话正在人们的日常交流中扮演着重要角色。表示现阶段正在进行的动作,用现在进行时;当主语后面有as well as短语时,谓语动词不受这些短语的影响,仍然与主语保持一致,主语是E-mail,故用is。 点评:英语中的时态主要由动词的形式决定,因此在学习英语时态时,要注意分析动词形式及具体语境,想象在那个特定的时间动作所发生的背景,这个动作是经常性动作、一般性动作、进行性动作、完成性动作还是将要发生的动作。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。 |
