New Understanding of Natural Silk's MysteriesNatural silk,as we all know,has a strength that man-made materials have long struggled to match.In a discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough,MIT re- searchers have discovered that silk gets its strength from its weakness.Or,more specifically,its many weak- nesses. Silk gets its extraordinary durability and ductility（柔韧性）from an unusual arrangement of hydrogen bonds that are intrinsically very weak but that work together to create a strong,flexible structure.Most materials一especially the ones we engineer for strength一get their toughness from brittleness.As such,natural silks like those produced by spiders have long fascinated both biologists and engineers because of their light weight,ductility and high strength(pound for pound,silk is stronger than steel and far less brittle). But on its face,it doesn't seem that silks should be as strong as they are;molecularly,they are held together by hydrogen bonds , which are far weaker than the covalent（共价的）bonds found in other molecules.To get a better understanding of how silk manages to produce such strength through such weak bonds, the MIT team created a set of computer models that allowed them to observe the way silk behaves at the atomic level. They found that the arrangement of the tiny silk nanocrystals（纳米晶体）is such that the hydro- gen bonds are able to work cooperatively,reinforcing one another against external forces and failing slowlywhen they do fail,so as not to allow a sudden fracture to spread across a silk structure.The result is natural silks that can stretch and bend while retaining a high degree of strength.But while that's all well and good for spiders,bees and the like,this understanding of silk geometry could lead to new materials that are stronger and more ductile than those we can currently manufacture.Our best and strongest materials are generally expensive and difficult to produce(requiring high temperature treatments or energy-intensive processes).By looking to silk as a model,researchers could potentially devise new manufacturing methods that rely on inexpensive materials and weak bonds to create less rigid,more forgiving materials that are nonetheless stronger than anything currently on offer. And if you thought you were going to get out of this materials science story without hearing about carbon nanotubes（纳米碳管）, think again. The MIT team is already in the lab looking into ways of synthesizing silk-like structures out of materials that are stronger than natural silk-like carbon nanotubes. Super-silks are on the horizon.If the hydrogen bonds break due to external forces,they break fast.A:RightB:WrongC:Not mentioned

第三篇The Science of the FutureUntil 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 1 996 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 ourdependence 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（灾难性的）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,in the Ukraine.Biotechnology is unlikely,however,to break its promises in quite the same or such a dangerous way.Organic chemistry helps to produce materials that areA:as good as wool. B:as good as an insect's body.C:not as good as natural materials. D:better than natural materials.
