1.All research to date on body image shows that women are much more critical of their appearance than men and much less likely to admire what they see in the mirror. Up to 8 out of 10 women are dissatisfied with their reflection,and more than half may see a distorted image.
2.Men looking in the mirror are more likely to be either pleased with what they see or indifferent. Research shows that men generally have a much more positive body-image than women一if anything,they may tend to over-estimate their attractiveness.Some men looking in the mirror may literally not see the flaws in their appearance. 3.Why are women too much more self-critical than men?Because women are judged on their appearance more than men,and standards of female beauty are considerably higher and more inflexible.Women are continually bombarded with images of the inflexible.Women are continually bombarded with images of the"ideal"face.And constant exposure to idealized images of female beauty on TV,magazines and billboards makes exceptional good looks seem normal and anything short of perfection seem abnormal and ugly.It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw throughout their entire adolescence. 4.Also,most women are trying to achieve the impossible:standards of female beauty have in fact become progressively more unrealistic during the last century.In 1917,the physically perfect woman was about 5 feet 4 inches tall and weighed nearly 10 stone（约140磅）.Even 25 years ago, top models and beauty queens weighed only 8% less than the average woman,now they weigh 23% less.The current media ideal for women is achievable by less than 5% of the female population一and that's just in terms of weight and size.If you want the ideal shape,face,etc, it's probably more like 1%. Today the percentage of women who have the ideal shape,face,etc is probably like________. A.literally not see the flaws in their appearance. B.1% C.smile at themselves D.standards of female beauty are considerably higher and more inflexible E.progressively more unrealistic F.5% [单项选择]运营在店铺里需要起到的作用是什么？（）
