1. 根据特定语境和时态标志考查现在完成时的影响性用法
(1)― ______ you ______ him around the museum yet?
― Yes. We had a great time there. (江苏卷)
A. Have; shown B. Do; show C. Had; shown D. Did; show
【解析】A。根据问句中的yet可知,所谈论的事情发生在最近的过去,且问话者很关心这个过去发生的事情对现在的影响和结果,所以用现在完成时。注意:不要受答语中过去式谓语had的影响而误选C。
(2)Professor James will give us a lecture on the Western culture, but when and where ______ yet. (浙江卷)
A. hasn’t been decided B. haven’t decided C. isn’t being decided D. aren’t decided
【解析】A。根据句意,此处应用被动语态,不用主动语态;再根据句末的yet可知,最好用现在完成时。故选A最佳。
