Today nanotechnology(纳米技术)is still in a formative phase. Yet it is maturing rapidly. Between 1997 and 2005, investment in nanotech research and development by governments around the world 【C1】______from $ 432 million to about $4.1 billion, and corresponding industry investment exceeded that of governments by 2005. By 2015, products incorporating nanotech will contribute approximately $ 1 _trillion to the global economy.
Descriptions of nanotech typically characterize it purely in terms of the minute size—assemblies between the size of an atom and about 100 molecular diameters(分子直径). That【C2】______makes it sound as though nanotech is merely looking to use infinitely smaller parts than conventional engineering. But rearranging the atoms and molecules leads to new【C3】______. One sees a transition between the fixed behavior of individual atoms and molecules and the adjustable behavior of collectives. Thus, nanotechnology might better be viewed as the【C4】______of quantum theory(量子论)and other nano-specific phenomena to fundamentally control the properties and behavior of matter.
The second stage, which began in 2005, focuses on active nanostructures that change their size, shape, conductivity or other properties during use. New drug-delivery particles could release therapeutic(治疗的)molecules in the body only after they reached their【C5】______diseased tissues. Electronic components such as transistors and amplifiers with adaptive functions could be reduced to single, complex molecules.
Starting around 2010, workers will【C6】______expertise with systems of nanostructures, directing large numbers of intricate components to specified ends. One application could involve the guided self-assembly of nanoelectronic components into three-dimensional circuits and whole devices. Medicine could employ such systems to improve the tissue compatibility of implants, or perhaps even to build【C7】______organs.
After 2015 -2020, the field will include molecular nanosystems. Whereas biological systems are water-based and markedly temperature-sensitive, these molecular nanosystems will be able to operate in a far wider range of environments and should be much faster. Computers and robots could be reduced to【C8】______small sizes. New interfaces linking people directly to electronics could change telecommunications.
Over time, therefore, nanotechnology should benefit every industrial sector and health care field. Nanotech does, however, pose new challenges to risk governance as well. Internationally, more needs to be done to collect the scientific information needed to resolve the【C9】______and to install the proper regulatory oversight. Helping the public to【C10】______nanotech soberly in a big picture that retains human values and quality of life will also be essential for this powerful new discipline to live up to its astonishing potential. [br] 【C7】
选项
答案
F
解析
根据空格后的organs可推断此处缺少形容词作定语。备选形容词中的artificial“人造的”与空格后的organs搭配使用,意为“人造器官”,build artificial organs与上文的improve the tissuecompatibility of implants相呼应,故[F]为答案。
