问题描述：
It is known to us all that email,as well as telephones,____ an important part in our daily life
A is playing B is played C are playing D play
说下原因
答
A is playing
as well as 连接两个名词作主语时,谓动要与前一个名词相一致.此题的前一个名词为email,因此谓动要用单三形式,又play an important part in 是email发出的动作,要用主动语态,故选A,不能选B.
答
A
主语是email,谓语动词用单数。主语是由as well as 连接的名词时，谓语的单复数与as well as 前面的名词保持一致。
答
选A。我们都知道电子邮件以及电话在我们的日常生活中起着重要作用。email是主语，as well as后面不算主语。
答
横线处可填play
答
A
as well as,together with,alone with都只强调前面的主语,所以后面谓语用单数
