【正确答案】 Actually the last fifty years was not the golden age of invention and innovation. From 1900 to 1950, human life was transformed by such invention as cars, aeroplanes, telephones, radios and television sets, not to mention nuclear weapons and the computer of course. In the recent 50 years since only a few inventions have been made, was the wellspring of invention drying up? Not likely. Indeed, a new age of invention is just be ginning.
