Answer 1

A
试题分析：A teacher and artist指的是同一个人，所以谓语动词用单数，且根据时间状语tomorrow afternoon，故用is。
考点：主谓一致的考查
点评：主谓一致指“人称”和“数”方面的一致关系。一般情况下，主谓之间的一致关系由以下三个原则的支配：语法一致原则 (grammatical concord) 意义一致原则 (notional concord) 就近原则 (principle of proximity)。“主谓一致”考查内容涉及名词单数或复数作主语、不可数名词作主语、不定代词作主语、并列结构作主语、特殊名词作主语时与谓语动词数的一致等。
