III. Words in Context: Choose the best answer. (各 1 分)In a talk given in 1959, Richard Feynman was the first scientist to suggest the possibility ofmaneuvering things atom by atom. Based on this innovative idea in physics, scientists began torealize Dr. Feynman’s theory in the 1990’s, and the __26__ research is now fully developedaround the world. This new technology of putting atoms where we want them to be is callednanotechnology, now widely applied in some manufacturing industries. Take packaging forexample. Nanotechnology helps produce thinner material for beer bottles, which __27__ have alighter weight and greater shelf-life. Reduced weight means transportation costs decline; greatershelf-life reduces __28__ and decreases overall costs to the end user. The clothing industry isalso starting to feel the effects of nanotech. Many manufacturers are currently using embeddednanoparticles to create stain-repellent khakis. This innovation will __29__ not only khaki wearers.Detergent makers, dry cleaners, and stain-removal makers will experience a sharp decrease incustomers. New materials produced through nanotech are not only used to improve existingproducts, but they are also extending their reach into areas formerly __30__ by metal, glass, andwood. This fairly low-tech application of nanotechnology is just the small tip of a vast iceberg,looming to sink even the “unsinkable” companies.
