Teaching tolerance is important 17 just because it is part of our American heritage but 18 the person who learns to be open to differences will have more opportunity in education, in business, and in so many 19 ways.

The dream
8、 is a dragon in every home. GeneDupe“s business is biotech pets. Not for Dr. Fril, though, the cloning of dead cats and dogs. He plans a range of entirely new animalsor, rather, of really quite old animals, with the twist that when they did exist, it was only in the imagination. Making a mythical cr
9、eature real is not easy. But GeneDupe“s team of biologists and computer scientists reckon they are equal to the task. Their secret is a new field, which they call “virtual cell biology“. Biology and computing have a lot in common, since both are about processing informationin one case electronic; in
10、 the other, biochemical. Virtual cell biology aspires to make a software model of a cell that is accurate in every biochemical detail. That is possible because all animal cells use the same parts listmitochondria for energy processing, the endoplasmic reticulum for making proteins, Golgi body for pr
11、otein assembly, and so on. Armed with their virtual cell, GeneDupe“s scientists can customize the result so that it belongs to a particular species, by loading it with a virtual copy of that animal“s genome. Then, if the cell is also loaded with the right virtual molecules, it will behave like a fer
12、tilized egg, and start dividing and developingfirst into embryo, and ultimately into an adult. Because this “growth“ is going on in a computer, it happens fast. Passing from egg to adult in one of GeneDupe“s enormous Mythmaker computers takes less than a minute. And it is here that Charles Darwin ge
13、ts a look in. With such a short generation time, GeneDupe“s scientists can add a little evolution to their products. Each computer starts with a search image (dragon, unicorn, griffin, etc), and the genome of the real animal most closely resembling it (a lizard for the dragon, a horse for the unicor
14、n and most taxingly, the spliced genomes of a lion and an eagle for the griffin). The virtual genomes of these real animals are then tweaked by random electronic mutations. When they have matured, the virtual adults most closely resembling the targets are picked and cross-bred, while the others are
15、culled. Using this rapid evolutionary process, GeneDupe“s scientists have arrived at genomes for a range of mythological creaturesin a computer, at least. The next stage, on which they are just embarking, is to do it for real. This involves synthesizing, with actual DNA, the genetic material that th
16、e computer models predict will produce the mythical creatures. The synthetic DNA is then inserted into a cell that has had its natural nucleus removed. The result, Dr. Fril and his commercial backers hope, will be a real live dragon, unicorn or what you have. Dr. Fril is confident about his new idea
17、. Indeed, if he can get the dragon“s respiration correct, he thinks they will set the world on fire.(分数:5.00)(1).Dr, Fril“s new ambition is to clone(分数:1.00)A.pets in general.B.rare animals.C.prehistoric animals.D.imaginary animals.(2).Mow GeneDupe“s scientists are trying to find out(分数:1.00)A.the e

21、anization. An important distinction concerning today“s cultural globalization is that it is largely driven by corporations, rather than countries. As such, one of the central concerns is the spread of consumer culture. For many critics, non-Western culture and practices are at risk of being overwhel
22、med by homogenizing “McDonaldization“. Skeptics contend that the erosion of culture has been overstated. They point to evidence that local culture remains strong. Cultural interactions have taken place for centuries so to argue non-Western cultural are somehow pure is naive. In a sense, the cultural
23、 degradation argument dismisses the ability of non-Western people to control their destiny and incorporate those attributes they may find useful. What is more, some argue that national identities are founded on real differences that have continued salience. Other skeptics point to the growth of ethn
24、ic and nationalist movements in the post-Cold War world as evidence that these sources of identity remain strong. Intense interaction may make people more cognizant of difference and lead to conflict. Information technology may, in fact, intensify traditional identities. Cultural globalization invol
