     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.

     Changing fashions are nothing more than the intentional creation of waste.Many women spend

large 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 changing their old-fashioned

dresses.Skirts are lengthened or shortened; neck-lines 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 necessary 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 time in his life smiled at the sight of a woman shaking in a thin dress on a winter day,

or 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? 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? That is for you to

decide.

医生和营养专家都说,黄曲霉素比三聚氰胺更可怕,比砒霜毒性大几十倍。那么有什么食物能消减黄曲霉素对人体的危害呢有专家撰文说,绿叶菜中的叶绿素能大幅度减少黄曲霉素的吸收率。
一家著名的医学杂志在2007年刊登了一项研究,该项研究发现天然叶绿素可以______黄曲霉素B1引起的大鼠多器官致癌作用。研究者表示,叶绿素的抗癌机制可能是因为它能大幅度减少黄曲霉素的吸收率,从而降低了黄曲霉素对肝脏DNA的加成作用。他们认为,叶绿素是一种极好的化学保护物质,对抗致癌物的作用非常有效,从减少吸收,到减少致癌物与遗传物质的作用,直到减少各组织的癌前病变出现,各环节都有明显效果。
当然,这只是一项动物研究,对人体来说,叶绿素是不是也有同样作用呢在大鼠试验的启发下,2009年有学者进行了一项人体试验,该研究证明,在人类志愿者中,叶绿素一样能有效地对抗黄曲霉素的致癌作用。研究者们给志愿者服用微量标记的黄曲霉素B,胶囊,然后正常进食和饮水,测定他们在72小时之内对黄曲霉素的吸收和代谢情况。若干天后,再给志愿者服用同样的黄曲霉素胶囊,但另加叶绿素或叶绿酸。结果和大鼠试验相当类似,叶绿素和叶绿酸能大大降低黄曲霉素的吸收率。
深绿色的叶菜,在世界上大部分国家里都价格高昂,难得中国人能吃上品种丰富、价格低廉的绿叶菜。但是我们似乎没有好好珍惜这种罕有的幸福和幸运,总把绿叶菜看成不值钱的东西、低档的食品,没有好好享受它的健康效益,真是太遗憾了。

黄曲霉素对人体不利,相关试验之所以可针对人体进行的原因有多种,其中不包括:

A.有志愿者愿意参加试验
B.服用的是微量标志的试验胶囊
C.试验只进行72小时
D.已有大鼠做过相关试验
