忽略题干语境所导致的错误 有的英语的时态考题特别注重利用题干本身所提供的语境进行考查。如果考生在做题时，只顾理解填空处的句意，而忽略对上下文语境的连贯理解，则可能步入命题人设计的陷阱。如：■ I was giving a talk to a large group of people, the same talk I _______ to half a dozen other groups. A. was giving B. am giving C. had given D. have given许多同学可能会简单地根据前面的 was giving 而误选 A。但事实上，此题提供的语境是：我当时正在给一群人作报告，这个报告我曾给其他若干批人讲过。由于 was giving 为过去进行时，而“曾给其他若干批人讲过”显然发生在 was giving 这一之前，故用过去完成时，即答案为 C。■ Father _______ for London on business upon my arrival, so I didn’t see him. A. has left B. left C. was leaving D. had left若单独看 Father _______ for London on business upon my arrival 这一句，则答案为 C 或D 均可。但是，若结合后面的 so I didn’t see him，则答案只能选 D。因为，既然“我没有见到他”用了过去时态，那么“父亲离开”就肯定属于“”，故要用过去完成时。
