Mother, where__ you put my cell-phone after you used it?选什么,为什么呢?
Mother,where __ you put my cell-phone after you used it? I ___ it anywhere.
A, have; haven't found B. had; didn't find
C. did; haven't found D. have; didn't find
这是一道时态题,不知道该选什么,怎么理解呢
放和找不到,都是发生在过去,哪个该表示有影响,哪个该表示没影响,怎么判断呢
Mother, where__ you put my cell-phone after you used it?选什么,为什么呢?Mother,where __ you put my cell-phone after you used it? I ___ it anywhere.A, have; haven't found B. had; didn't findC. did; haven't found D. have; didn't find这是
选C.
原因：从used（使用过）可以知道要用过去时态,本句话有实意动词put,所以第一空填did;回答说的意思是：我找了好多地方都没有发现,所以后面用一般现在完成时.故选：C.
did, haven't found
