28.A细节理解题。根据第二段的内容,尤其是“‘You don't get bothered by the rain,sunshine,or the fact that your kidsare waiting in the parking lot.All your focus is on the shopping experience.This technique also prevents shoppersfrom noticing that it's getting dark out.”可知,没有窗户的杂货店会让购物者沉浸在购物中。
29.D推理判断题。根据第三段Margine Biswas所说的话可知,窗户透光,从而导致食物快速变质或包装褪色,并且窗户会减少展出商品的空间,此外,窗户也没有墙承重。由此可推断,Margine Biswas主要说明窗户对杂货店来说没有什么益处。
