Question

这道题我觉得选A和选D都对,请指教,D是主语从句
35．… Why were you so late for work today?
--- to the office was very slow this morning because of the traffic.
A．Driving B．I drove C．To drive D．That I drove

Answer 1

只能选A.因为选d 的话 that I drove to the office 作主语,这件事情不能说“was very slow (很慢)”,而如果把that直到morning 看作主语的话,就没有谓语动词了.
