问题         Most scholars agree that Isaac Newton, while formulating the laws of force and gravity and inventing the calculus in the late 1600s, probably knew all the science there was to know at the time.In the【C1】ens_________350 years and estimated 50 million research papers and innumerable books have been published in the natural sciences and mathematics.The modem high school student probably now possesses【C2】_________scientific knowledge than Newton did, yet science to many people seems to be an impenetrable mountain of facts.

        One way scientists have tried to cope with this mountain is by becoming more and more【C3】_________ (specialize).Another【C4】 str_________for coping with the mountain of information is to largely ignore it.That shouldn’t come as a surprise.Sure, you have to know a lot to be a scientist, but【C5】 kn_________a lot is not what makes a scientist.What makes a scientist is ignorance.This may sound ridiculous, but for scientists the facts are just a starting place.In science, every new discovery raises 10 new questions.
        By this calculus, ignorance will always grow faster【C6】 _________knowledge.Scientists and laypeople【C7】_________ (alike) would agree that for all we have come to know, there is for more we don’t know.More important, every day there is far more we know we don’t know.One crucial outcome of scientific knowledge is to generate new and better ways of being ignorant:not the kind of ignorance that is associated 【C8】_________a lack of curiosity or education but rather a cultivated, high-quality ignorance.They do it in grant proposals and over beers at meetings.As James Clerk Maxwell, probably the greatest physicist between Newton and Einstein, said, "Thoroughly conscious ignorance...is a prelude to every real advance in knowledge."
        This perspective on science—that it is about the questions more than the answers—should come as something of a relief.It makes science less【C9】_________(threat) and far more friendly and, in fact, fun.Science becomes a series of elegant puzzles and puzzles within puzzles—and who doesn’t like puzzles? Questions are also more【C10】_________(access) and often more interesting than answers; answers tend to be the end of the process, whereas questions have you in the thick of things.
【C9】
