It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can’t be controlled, and may have unforeseen limitations; but if efforts to understand and master stem?cell development prove successful, doctors will have a therapeutic tool of incredible power.
The same applies to cloning, which is really just the other side of the coin; true cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full?fledged animal, genetically identical to its parent.
For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year.
Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true “miracle cure.”
21.The writer holds that the potential to make healthy body tissues will
[A] aggravate moral issues of human cloning.
bring great benefits to human beings.
[C] help scientists decode body instructions.
[D] involve employing surgical instruments.
22.The word “rejuvenated” (Para. 5) most probably means
[A] modified. re-collected. [C] classified. [D] reactivated.
23.The research at the University of Wisconsin is mentioned to show
[A] the isolation of stem cells. the effects of gene therapies.
[C] the advantages of human cloning. [D] the limitations of tissue replacements.
24.Which of the following is true according to the text?
[A] The principle of gene therapy is applicable to that of cloning.
The isolation of stem cells is too difficult to be feasible.
[C] It is reasonable for all body instructions to be activated.
[D] Cloned animals will eventually take control of the world.
25.Towards the genetic research, the author’s attitude can best be said to be that of
[A] Frustration. Indifference. [C] Amazement. [D] Opposition.

What our society suffers from most today is the absence of consensus about what it and life in it ought to be; such consensus cannot be gained from society’s present stage, or from fantasies about what it ought to be. For that the present is too close and too diversified, and the future too uncertain, to make believable claims about it. A consensus in the present hence can be achieved only through a shared understanding of the past, as Homer’s epics informed those who lived centuries later what it meant to be Greek, and by what images and ideals they were to live their lives and organize their societies.
Most societies derive consensus from a long history, a language all their own, a common religion, common ancestry. The myths by which they live

The basic function of money is the enable buying to be separated from selling, thus permitting trade to take place without the so瞔alled double coincidence of barter.If a person has something to sell and wants something else 1 return, it is not necessary to search for someone able and 2to make the desired exchange of items.The person can sell the 3 item for general purchasing power—that is, money—to anyone who wants to buy it and then use the proceeds to buy the desired item from anyone who wants to sell it.
The importance of this function of money is 4 illustrated by the experience of Germany just after World War Ⅱ, 5 paper money was 6 largely useless because, despite inflationary conditions, price controls were effectively 7 by the American, French, and British armies of occupation.People had to8 to barter or to inefficient money substitutes.The result was to cut total output of the economy in half.The German economic miracle just after 1948 reflected partly a currency reform by the occupation authorities, 9 some economists hold that it stemmed primarily from the German government‘s 10 of all price controls, 11 permitting a money economy to 12 a barter economy.
