C.Have you seen
——你看以我的词典了吗?（要用完成时,因为这表示了“结果,影响”）
——是的,一分钟前,我看到它在你桌上.（显然回答应该用过去式.）可是下文是很明显的一般过去式啊 ，我们通常不是说上下文时态要保持一致吗？还有，下文 yse 之后不是逗号吗？如果是句号 我觉得选c好 可是逗号，只有联系后文好像A 好吧Yes , I have ,I saw it ....这是很常见的。Where have you been?I haven't seen you for a whole morning?I went to the post office this morning.Have you ever been to the Great Wall?Yes, (I have ), I went there last year.我觉得理由有些有些牵强能给俺找点这种类型题吗？MissGreenisn'tintheoffice . she_______tothelibrary .A.hasgone B. wentC.willgoD.hasbeen—______ you ___ yourhomeworkyet ?—Yes .
