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 2020, 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.
【C16】
选项 A、advisable
B、affordable
C、available
D、valuable
答案C
解析 句意理解。根据下文"or when human cloning will be perfected，or when time travel willbe possible"中的perfected(完善的)和possible(有可能的)两个形容词，可知本题中也应该选择一个与之感情色彩及含义相近的词，即：“超越光速的旅行是否可行”。available意为“可利用的，可行的”，符合句子意思，与下文构成排比句式。affordable意为“付得起的，有支付能力的”，advisable意为“明智的，可取的”，valuable意为“贵重的”，均不符合句意。
