9、T 1. 20 Paolo Fril, chairman and scientific officer of GeneDupe, based in San Melito, California, is a man with a dream. The dream is a dragon in every home. GeneDupes business is biotech pets. Not for Dr. Fril, though, the cloning of dead cats and dogs. He plans a range of entirely new animals or,
10、rather, of really quite old animals, with the twist that when they did exist, it was only in the imagination. Making a mythical creature real is not easy. But GeneDupes team of biologists and computer scientists reckon they are equal to the task. Their secret is a new field, which they call “virtual
11、 cell biology“. Biology and computing have a lot in common, since both are about processing information in one case electronic: in 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
12、 cells use the same parts list mitochondria for energy processing, the endoplasmic reticulum for making proteins , Golgi body for protein assembly, and so on. Armed with their virtual cell, GeneDupes scientists can customize the result so that it belongs to a particular species, by loading it with a
13、 virtual copy of that animals genome. Then, if the cell is also loaded with the right virtual molecules, it will behave like a fertilized egg, and start dividing and developing first into embryo, and ultimately into an adult. Because this “growth“ is going on in a computer, it happens fast. Passing
14、from egg to adult in one of GeneDupes enormous Mythmaker computers takes less than a minute. And it is here that Charles Darwin gets a look in. With such a short generation time, GeneDupes scientists can add a little evolution to their products. Each computer starts with a search image(dragon, unico
15、rn, griffin, etc), and the genome of the real animal most closely resembling it(a lizard for the dragon, a horse for the unicorn 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.
16、When they have matured, the virtual adults most closely resembling the targets are picked and cross-bred, while the others are culled. Using this rapid evolutionary process, GeneDupes scientists have arrived at genomes for a range of mythological creatures -in a computer, at least. The next stage, o
17、n which they are just embarking, is to do it for real. This involves synthesizing, with actual DNA, the genetic material that the 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
18、 and his commercial backers hope, will be a real live dragon, unicorn or what you have. Dr. Fril is confident about his new idea. Indeed, if he can get the dragons respiration correct, he thinks they will set the world on fire. 21 Dr. Frits new ambition is to clone ( A) pets in general. ( B) rare an
19、imals. ( C) prehistoric animals. ( D) imaginary animals. 22 Now GeneDupes scientists are trying to find out ( A) the existence of mythical animals. ( B) the causes for the extinction of some animals. ( C) the similarities between biology and computing. ( D) the possibilities of creating mythical cre
20、atures. 23 The research is based on ( A) general genetic engineering theory. ( B) the development of computing technology. ( C) the theory of cross-breeding of different species. ( D) animals biochemical information processing. 24 The team has chosen a lizard for the dragon as they think these creat
21、ures ( A) have the same genome. ( B) have similar appearances. ( C) belong to the same species. ( D) possess the same genetic structure. 25 Dr. Fril and his team think they will succeed ( A) with the advancement of computer sciences. ( B) as they have worked out genomes by computer. ( C) when they f
22、ind the actual DNA. ( D) if they get enough commercial backers. 25 Cultural globalization, for many, means Westernization or Americanization. An important distinction concerning todays cultural globalization is that it is largely driven by corporations, rather than countries. As such, one of the cen
23、tral concerns is the spread of consumer culture. For many critics, non-Western culture and practices are at risk of being overwhelmed by homogenizing “ Mc-Donaldization“. Skeptics contend that the erosion of culture has been overstated. They point to evidence that local culture remains strong. Cultu
24、ral interactions have taken place for centuries so to argue non-Western cultural are somehow pure is naive. In a sense, the cultural 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 arg
