synthetic material 合成的【查看更多】

閱讀理解

　　A wallet that looks like a piece of newspaper, an atlas, or an express parcel receipt? Or a business card that looks like a notepad? No kidding．

　　Bai Minghui, a Beijing-based designer, creates his artwork using Tyvek, a synthetic(合成的)paper material which is difficult to tear, waterproof and, more importantly, totally recyclable．

　　Born to a worker family in 1983 in Tangshan, Hebei Province, Bai worked as a graphic designer at a financial magazine in Beijing after graduating from Minzu University of China．

　　In the spring of 2008, Bai visited an exhibition about Tyvek in Beijing’s 798 art zone, and then worked with the material, trying to bring his designs to life．The first thing that came into his mind was the paper wallet, a must-try handicraft assignment(手工作業(yè))that most Chinese students do in elementary school．

　　“A paper wallet is definitely more useful than a paper crane or frog,” Bai told Beijing Review, smiling．“At first, many people have no idea what it is, because it looks like a piece of newspaper or an express parcel receipt, and feels like real paper．But it’s hard to tear．”

　　“The completed, folded wallet is seamless(無縫的), which creates so much fun for a designer．To be honest, I didn’t think about profits at all,” he said．

　　After months of research and development on printing and designing, the first generation of his paper wallet made a stunning debut(上市)in May 2008．The second generation, which offers a greater range of pattern options, was put on the market at the beginning of 2009．

　　“You can have graffiti(涂鴉)or write down phone numbers on it, or paint whatever you like．I would like people to be able to use it easily,” he said．“I don’t want to do things without creative ideas．Now my focus is on how to create better design rather than the wallet itself．”

Until recently, the “science of the future” was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.

Organic chemistry enables us to produce marvelous synthetic(合成的) materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.

Nevertheless, scientists in the laboratory have already succeeded in “growing” a material that has many of the characteristics of human skin. The next step may well be “biotech hearts and eyes” which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.

The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic(災(zāi)難性的) levels unless we develop power sources that are both cheaper and cleaner.

It is attempting to think that biotechnology or some other “science of the future” can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl(切爾諾貝利), in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.

68.According to the passage, the science of the future is likely to be __________.

A. electronics B. biotechnology C. genetic engineering D. nuclear technology

69. Organic chemistry helps to produce materials that are __________.

A. as good as wool B. as good as an insect’s body

C. not as good as natural materials D. better than natural materials.

70. According to the passage, it may soon be possible__________.

A. to make something as good as human skin B. to produce drugs without side effects

C. to transplant human organs D. to make artificial hearts and eyes

71. In 1996, Arthur C. Clarke predicted that ___________.

A. biological power sources would be put into use soon

B. oil, gas and coal could be repeatedly used in the future

C. dependence on non-renewable power sources would be reduced soon

D. the Chernobyl disaster would happen in two years

72. What do we learn from the last paragraph?

A. Biotechnology can solve all our future energy problems.

B. Biological power is cheaper than nuclear power.

C. Biological power may not be as dangerous as nuclear power.

D. Biological power will keep all its promises.
