单选题 The president of the college, together with the deans, ______ a conference for the purpose of laying down certain regulations.
A. is planning B. are planning
C. are to plan D. have planned

【正确答案】 A

【答案解析】[解析] 本句的主语是the President of the college．因此谓语动词用第三人称单数。以A together with B作主语时，谓语的性、数和人称与名词A保持一致，不受B的影响。类似的说法还有：A as well as B，A in addition to B，A accompanied by B，A and not B等，在这些说法中，名词A作主语，谓语应与A保持一致，不受B的影响。
