the trouble. If we can understand how cancer works, we can counteract its action. 63. The example of Pasteur in the passage is used to ________. [A] predict that the secret of cancer will be disclosed in a decade [B] indicate that the prospects for curing cancer are bright [C] prove that cancer will be cured in fifty to sixty years [D] warn that there is still a long way to go before cancer can be conquered 64.

The word dormant in the third paragraph most probably means ________. [A] dead [B] everpresent [C] inactive [D] potential Passage 5 Discoveries in science and technology are thought by untaught minds to e in blinding flasher or as the result of dramatic accidents. Sir Alexander Fleming did not, as legend would have it, look at the mold on a piece of cheese and get the idea for penicillin there and then. He experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always e out of laborious trial and error. Innovation is like soccer。 even the best players miss the goal and have their shots blocked much more frequently than they score. They point is that the players who score most are the ones who take the most shots at the goal— and 7 so it goes with innovation in any field of activity. The prime difference between innovators and others is one of approach. Everybody gets ideas, but innovators work consciously on theirs, and they follow them through until they prove practicable or otherwise. What ordinary people see as fanciful abstractions, professional innovators see as solid possibilities. Creative thinking may mean simply the realization that there39。 s no particular virtue in doing things the way they have always been done, wrote Rudolph Flesch, a language authority. This accounts for our reaction so seemingly simple innovations like plastic garbage bags and suitcases on wheels that make life more convenient: How e nobody thought of that before? The creative approach begins with the proposition that nothing is as it appears. Innovators will not accept that there is only one way to do anything. Faced with getting from A to B, the average person will automatically set out on the bestknown and apparently simplest route. The innovator will search for alternate courses, which may prove easier in the long run and are bound to be more interesting and challenging even if they lead to dead ends. Highly creative individuals really do march to a different drummer. 67. What does the author probably mean by untaught mind in the first paragraph? [A] A person ignorant of the hard work involved in experimentation. [B] A citizen of a society that restricts personal creativity. [C] A person who has had no education. [D] An individual who often es up with new ideas by accident. 68. According to the author, what distinguishes innovators from noninnovators? [A] The variety of ideas they have. [B] The intelligence they possess. [C] The way they deal with problems. [D] The way they present their findings. 69. The author quotes Rudolph Flesch in Paragraph 3 because ________. [A] Rudolph Flesch is the bestknown expert in the study of human creativity [B] the quotation strengthens the assertion that creative individuals look for new ways of doing things [C] the reader is familiar with Rudolph Flesch39。 s point of view [D] the quotation adds a new idea to the information previously presented 70. The phrase march to a different drummer (the last line of the passage) suggests that highly creative individuals are ________. 8 [A] diligent in pursuing their goals [B] reluctant to follow mon ways of doing things [C] devoted to the progress of science [D] concerned about the advance of society 9 Unit 2 Passage 1 Money spent on advertising is money spent as well as any I know of. It serves directly to assist a rapid distribution of goods at reasonable price, thereby establishing a firm home market and so making it possible to provide for export at petitive prices. By drawing attention to new ideas it helps enormously to raise standards of living. By helping to increase demand it ensures an increased need for labour, and is therefore an effective way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television licence would need to be doubled, and travel by bus or tube would cost 20 per cent more. And perhaps most important of all, advertising provides a guarantee of reasonable value in the products and services you buy. Apart from the fact that twentyseven acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for mercifully the public has the good sense not to buy the inferior article more than once.
