Millions of individuals became (1) in a variety of aerobic activities, and (2) thousands of health spas (3) around the country t

A number of fitness spas existed (5) to this aerobic fitness movement, even a national chain with spas in most major cities. However, their (6) was not on aerobics, (7) on weight-training programs de signed to de
3、velop muscular mass, (8) , and endurance in their primarily male (9) These fitness spas did not seem to benefit (10) from the aerobic fitness movement to bet ter health, since medical opinion suggested that weight-training programs (11) few, if (12) , health benefits. In recent years, however, weigh

(15) , most physi cal-fitness tests have usually included measures of muscular strength and endurance, not for he
5、alth-related reasons, but primarily (16) such fitness components have been related to (17) in athletics. (18) , in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health (19) as well. The American College of

But there will be others as well. Here is one of the remarkable therapies on the cutting edge of
10、genetic research that could make their way into mainstream medicine in the coming years.While its true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells
11、is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells havent begun to specialize.Yet this untapped potential could be a terrific boon to medici
12、ne. Most diseases involve the death of healthy cellsbrain cells in Alzheimers, cardiac cells in heart disease, pan creatic cells in diabetes, to name a few. If doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue.It was in
13、credibly difficult, but last fall scientists at the University of Wisconsin man aged to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still cant be controlled, and may have unforeseen limitations; but if ef forts to understand and master stem-cell devel
14、opment 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 clo ning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, reset
15、ting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, ge netically 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 v
16、alue, 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
17、 legally and emo tionally 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.
18、That could prove to be a true “miracle cure. /(分数:5.00)(1).The writer holds that the potential to make healthy body tissues will_.(分数:1.00)A.aggravate moral issues of human cloningB.bring great benefits to human beingsC.help scientists decode body instructionsD.involve employing surgical instruments
19、(2).The word “rejuvenated“ ( Par(分数:1.00)A.5 ) most probably means_.A. modifiedB. re-collectedC. classifiedD. reactivated(3).The research at the University of Wisconsin is mentioned to show_.(分数:1.00)A.the isolation of stem cellsB.the effects of gene therapiesC.the advantages of human cloningD.the l
20、imitations of tissue replacements(4).Which of the following is true according to the text?(分数:1.00)A.The principle of gene therapy is applicable to that of cloning.B.The isolation of stem cells is too difficult to be feasible.C.It is reasonable for all body instructions to be activated.D.Cloned anim
21、als will eventually take control of the worl(5).Towards the genetic research, the authors attitude can best be said to be that of_.(分数:1.00)A.frustrationB.indifferenceC.amazementD.opposition1What our society suffers from most today is the absence of consensus about what it and life in it ought to be
22、; such consensus cannot be gained from societys present stage, or from fantasies about what it ought to be. For that the present is too close and too diversi lied, and the future too uncertain, to make believable claims about it. A consensus in the present hence can be achieved only through a shared
23、 understanding of the past, as Homers 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 com mon religion,
24、common ancestry. The myths by which they live are based on all of these. But the United States is a country of immigrants, coming from a great variety of na tions. Lately, it has been emphasized that an asocial, narcissistic personality has become characteristic of Americans, and that it is this typ
