【答】1.如果What在主语从句中不是主语,则从句的谓语动词应该根据主语的数来决定,与what无关。例如:What I am most interested in is/are your immediate personal reactions. 我最感兴趣的是你本人马上作出的反应。/ What we need is/are a few bright young engineers. 我们所需要的是几位聪明的年轻工程师。(摘自《牛津英语用法指南》第三版529.2节)
2.如果What在主语从句中充当主语,则从句的谓语动词用单数。例如:What is most important in life isn't money. 人生最重要的并非金钱。(摘自外研社、建宏《英汉多功能词典》)
