( = The child is lively as well as healthy. )这孩子既健康又活泼。 【横向辐射】bothand& eitheror 1.bothand意为“不但而且;既又”,相当于not onlybut also,用来连接两个对等的成分,当它连接两个并列主语时,谓语动词要用复数形式。如:He can both draw and sing. 他既会画画,也会唱歌。Both my mother and my father like playing computer games. 我爸爸和妈妈都喜欢玩电脑游戏。2.eitheror 意为“或者或者、要么要么”,neithernor意为“既不也不”,它们都可用来连接两个在语法功能上相同,在结构上相称的并列成分。当它们连接两个并列主语时,谓语应与or或nor后面的主语在人称和数上保持一致。如:Neither Tom nor Sam has the ticket for the film. 汤姆和萨姆都没有电影票。Either you or I am right. 不是你对,就是我对。【课堂变式】1.Do you think most of the people in Beijing can talk with foreigners in English?
