The reason much refrigerated food spoils is that it ends up out of sight at the back of the shelf. So why not have round shelves that rotate? Because such rotating shelves would havejust the same sort of drawback, since things would fall of the shelves’ edges into the rear corners.
--Which of the following is presupposed in the argument against introducing rotating shelves?
(A) Refrigerators would not be made so that their interior space is cylindrical.
(B) Refrigerators would not be made to have a window in front for easy viewing of their contents without opening the door.
(C) The problem of spoilage of refrigerated food is not amenable to any solution based on design changes.
(D) Refrigerators are so well designed that there are bound to be drawbacks to any design change.
(E) Rotating shelves would be designed to rotate only while the refrigerator door was open.

the objection of using round shelves that rotate is that things
would fall of the shelves’ edges into the rear corners.
then focus on this point. why can thing fall? that is because the
interior space of our refrigerator is solid rectangle in shape.
just use your imagination, if it is cylindrical with round shelves,
then things cannot fall.作者: dumengxuan 时间: 2012-3-29 06:56
想象力缺乏真是致命伤啊
圆形搁板内切于冰箱内才导致东西会掉下来
若搁板与冰箱内部空间是密合的就不会发生
