答案(点此获取答案解析)

故事中的记号作为参照物,人和记号之间没有发生位置的变化,以记号为参照物,人是静止的.掉到江里的箭和记号之间发生了位置的变化,以记号为参照物,箭是运动的.所以没有通过“刻舟”而求得剑,是由于他不懂得运动和静止的相对性.

根据短文理解,选择正确答案。

    If women are mercilessly exploited(剥削)year after year,they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion,they are always taken advantage of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it,only a woman is capable of standing in front of a wardrobe(衣橱)packed full of clothes and announcing sadly that she has nothing to wear.

    Changing fashions are nothing more than the intentional creation of waste.Many women spend vast sums of money each year to replace clothes that have hardly been worn.Women who cannot afford to throw away clothing in this way,waste hours of their time altering(政变)the dresses they have.Skirts are lengthened or shortened;neck-line are lowered or raised,and so on.

    No one can claim that the fashion industry contributes anything really important to society.Fashion designers are rarely concerned with vital things like warmth,comfort and durability(耐用).They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort,as long as they look right.There can hardly be a man who hasn't at some times in his life smiled at the sight of a woman shaking in a thin dress on a winter day,or delicately picking her way through deep snow in high-heeled shoes.

    When comparing men and women in the matter of fashion,the conclusions to be drawn are obvious.Do the constantly changing fashions of women's clothes,one wonders,reflect basic qualities of inconstancy and instability (不稳定)?Men are too clever to let themselves be cheated by fashion designers.Do their unchanging styles of dress reflect basic qualities of stability and reliability(可靠)?That is for you to decide.
