问题     According to BT’s futurologist, Ian Pearson, these are among the developments scheduled for the first few decades of the new millennium(a period of 1,000 years), 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【C2】______millennium technology calendar that gives the latest dates when we can expect hundreds of key【C3】______and discoveries to take place. Some of the biggest developments will be in medicine, including an【C4】______life expectancy and dozens of artificial organs【C5】______into use between now and 2040.
    Pearson also【C6】______a breakthrough in computer human links. "By linking【C7】______to our nervous system, computers could pick up【C8】______we feel and, hopefully, simulate【C9】______too so that we can start to【C10】______full sensory environments, rather like the holidays in Total Recall or the Star Trek holodeck," he says.
    But that, Pearson points【C11】______is only the start of man-machine【C12】______: "It will be the beginning of the long process of integration that will【C13】______lead to a fully electronic human before the end of the next century."【C14】______his research, Pearson is able to put dates to most of the breakthroughs that can be predicted. However, there are still no【C15】______for when faster-than-light travel will be【C16】______or when human cloning will be perfected, or when time travel will be possible.
    But he does【C17】______social problems as a result of technological advances. A boom in neighborhood surveillance cameras will, for example,【C18】______problems in 2010, while the arrival of synthetic【C19】______robots will mean people may not be able to【C20】______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. [br] 【C4】
选项 A、expanded
B、extended
C、enlarged
D、enriched
答案 B
解析 动词辨析题。expanded表示“膨胀的，扩张的”；extended表示“伸出的，延长的”；enlarged表示“放大的，扩大的”；enriched“表示浓缩的，强化的”。此处表示“被延长的寿命”，所以用extended life expectancy，B为正确答案。
