问题 According to Ian Pearson, a futurologist, these are among the developments scheduled for the first few decades of the new millennium, when supercomputers will dramatically accelerate progress in all areas of life.
Pearson has【C1】______together the work of hundreds of researchers around the world to produce a unique millennium technology calendar that gives the latest dates when we can expect hundreds of key【C2】______and discoveries to take place. Some of the biggest developments will be in medicine, including an【C3】______life expectancy and dozens of artificial【C4】______coming into use between now and 2040.
Pearson also has【C5】______a breakthrough in computer-human links. "By linking directly to our nervous system, computers could pick up what we feel and, hopefully, simulate feeling too so that we can start to【C6】______full sensory environments, rather like the holidays in Total Recall or the Star Trek holodeck," he says.
But that, Pearson points out, is only the start of man-machine【C7】______: "It will be the beginning of the long process of integration that will ultimately lead to a fully electronic human before the end of the next century." Through his research, Pearson is able to put dates to most of the breakthroughs that can be predicted. However, there are still no【C8】______for when faster-than-light travel will be【C9】______, or when human cloning will be perfected, or when time travel will be possible.
But he does expect social problems as a result of technological advances. A boom in neighborhood surveillance cameras will, for example, cause problems in 2018, while the arrival of synthetic life like robots will mean people may not be able to【C10】______between their human friends and the droids. And home appliances will also become so smart that controlling and operating them will result in the breakout of a new psychological disorder-kitchen rage.
A. made B. breakthroughs C. integration D. expanded
E. pieced F. predicted G. extended H. develop
I. findings J. forecasts K. available L. organs
M. distinguish N. affordable O. differ [br] 【C3】
选项
答案 G
解析 extended，词义辨析题。根据词性，此处应当填入形容词。要注意动词的-ed，-ing形式也具有形容词功能，故可选范围为“expanded，predicted，extended，available，affordable”。此处指寿命的延长，故选extended。注意expand与extend的区别：expand扩张(体积、面积上的)，侧重指“上下、左右、前后的面或体的伸展”，如：Iron expands when it is heated．铁加热时就膨胀；extend延长(线性的)，可以表示时间和空间的“延长”，还可以用于比喻意义上的“延长”，或范围的“扩展”。如：the extended meaning of a word(词汇的引申意义)，to extend(or lengthen)a road(延长道路)，to extend(or lengthen)one’s stay(延长某人的逗留)。
