……好吧
What the matter was with him 这句话怎么理解呢?如果what是表语,the matter是主语,was是谓语,with him是状语对吧?还原句型就是the matter was what with you?不觉得别扭吗?
实际上what 是主语,was是谓语,the matter是表语,这个句子的正常语序就是what was the matter with him?所以A选项的语序其实是颠倒了表语和谓语的位置.
B选项就是陈述语序,what 是主语,句子是主系表加状语结构.
对主语提问的句子的语序都不用变,因为特殊疑问句中疑问词要提前,而疑问词本身就是主语.
