问题:

Any normal species would be delighted at the prospect of cloning. No more nasty surprises like sickle cell or Down syndrome--just batch after batch of high-grade and, genetically speaking, immortal offspring! But representatives of the human species are responding as if someone had proposed adding Satanism to the grade-school Curriculum. Suddenly, perfectly secular folks are throwing around words like sanctity and retrieving medieval-era arguments against the pride of science. No one has proposed burning him at the stake, but the poor fellow who induced a human embryo to double itself has virtually recanted proclaiming his reverence for human life in a voice, this magazine reported," choking with emotion."

There is an element of hypocrisy to much of the anti-cloning furor, or if not hypocrisy, superstition. The fact is we are already well down the path leading to genetic manipulation of the creepiest sort. Life-forms can be patented, which means they can be bought and sold and potentially traded on the commodities markets. Human embryos are life-forms, and there is nothing to stop anyone from marketing them now, on the same shelf with the Cabbage Patch dolls.

In fact, any culture that encourages in vitro fertilization has no right to complain about a market in embryos. The assumption behind the in vitro industry is that some people’s genetic material is worth more than others’ and deserves to be reproduced at any expense. Millions of low-income babies die every year from preventable ills like dysentery, while heroic efforts go into maintaining yuppie zygotes in test tubes at the unicellular stage. This is the dread "nightmare” of eugenics in familiar, marketplace form which involves breeding the best-paid instead of the best. Cloning technology is an almost inevitable byproduct of in vitro fertilization. Once you decide to go to the trouble of in vitro, with its potentially hazardous megadoses of hormones for the female partner and various indignities for the male, you might as well make a few backup copies of any viable embryo that’s produced. And once you’ve got the backup organ copies, why not keep a few in the freezer, in case Junior ever needs a new kidney or cornea

The critics of cloning say we should know what we’re getting into, with all its Orwellian implications. But if we decide to outlaw cloning, we should understand the implications of that. We would be saying in effect that we prefer to leave genetic destiny to the crap shooting of nature, despite sickle-cell anemia and Tay-Sachs and all the rest, because ultimately we don’t trust the market to regulate life itself. And this may be the hardest thing of all to acknowledge: that it isn’t so much 21st century technology we fear, as what will happen to that technology in the hands of old-fashioned 20th century capitalism.

材     料经济学道理
2008年大蒜的价格跌入低谷,最低时降到了每公斤1毛钱,这成为大蒜种植面积萎缩的根源。
2008年大蒜种植面积下降,直接导致了2009年的大蒜产量急剧下降,在很大程度上推高了大蒜的价格。
民众普遍认为大蒜能够杀菌、提高身体免疫力,甚至能够避免感染甲流,这对大蒜价格的上扬起到了推波助澜的作用。
种植一亩地的大蒜,种子、化肥、农药等各种费用要1000多元,大蒜价格至少在每公斤2元以上,蒜农才有利润。
大蒜价格大幅上涨,经销商们获得暴利,不少外行人也眼热起来,纷纷加入大蒜交易行列,有的人甚至大量囤积大蒜。
某市民说:“现在大蒜也太贵了,我都一直忍着没买,但这么久价格都不降,只好少买点。”
2010年5月14日、19日、24日,国家发改委三谈物价,表示要指导各级价格主管部门,加强对大蒜等出现异常波动或者可能出现异常波动的商品价格监测预警。
