7、cipated Section BWhy arent you curious about what happened?A “You suspended Ray Rice after our video,” a reporter from TMZ challenged National Football League Commissioner Roger Goodell the other day. “Why didnt you have the curiosity to go to the casino (赌场)yourself ?” The implication of the questi
8、on is that a more curious commissioner would have found a way to get the tape.B The accusation of incuriosity is one that we hear often, carrying the suggestion that there is something wrong with not wanting to search out the truth,” have been bothered for a long time about the curious lack of curio
9、sity,” said a Democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an assistant to New Jersey Governor Chris Christie who chose not to ask hard questions about the George Washington Bridge traffic scandal. “Isnt the mainstream
10、 media the least bit curious about what happened?” wrote conservative writer Jennifer Rubin earlier this year, referring to the attack on Americans in Benghazi, Libya.C The implication, in each case, is that curiosity is a good thing,and a lack of curiosity is a problem. Are such accusations simply
11、efforts to score political points for ones party? Or is there something of particular value about curiosity in and of itself?D The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your Future Depends on It, insists that the answer to that last question is Yes.
12、 Leslie argues that curiosity is a much-overlooked human virtue, crucial to our success, and that we are losing it.E We are suffering, he writes, from a “serendipity deficit.” The word “serendipity” was coined by Horace Walpole in an 1854 letter, from a tale of three princes who “were always making
13、discoveries, by accident, of things they were not in search of.” Leslie worries that the rise of the Internet, among other social and technological changes, has reduced our appetite for aimless adventures. No longer have we the inclination to let ourselves wander through fields of knowledge, ready t
14、o be surprised. Instead, we seek only the information we want.F Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. We will see unimaginative governments and dying corporations make disastrous decisions. We will lose a vital part of what has m
15、ade humanity as a whole so successful as a species.GLeslie presents considerable evidence for the proposition that the society as a whole is growing less curious. In the U.S. and Europe, for example, the rise of the Internet has led to a declining consumption of news from outside the readers borders
16、. But not everything is to be blamed on technology. The decline in interest in literary fiction is also one of the causes identified by Leslie. Reading literary fiction, he says, makes us more curious.H Moreover, in order to be curious, you have to be aware of a gap in your knowledge in the first pl
17、ace. Although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we dont know, hes surely right to point out that the problem is growing: “Google can give us the powerful illusion that all questions have definite answers.”I Indeed, Google, for which Leslie expr
18、esses admiration, is also his frequent whipping boy (替 罪羊) He quotes Google co-founder Larry Page to the effect that the “perfect search engine” will “understand exactly what I mean and give me back exactly what I want.” Elsewhere in the book, Leslie writes: “Google aims to save you from the thirst
19、of curiosity altogether.”JSomewhat nostalgically (怀旧地),he quotes John Maynard Keyness justly famous words of praise to the bookstore: “One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as c
20、uriosity dictates, should be an afternoons entertainment.” If only!K Citing the work of psychologists and cognitive (认知的)scientists,Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key
21、factorand a difficult one to preserve. If not cultivated, it will not survive: “Childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone.”L School education, he warns, is often conducted in a way that makes children incurious. Children of educate
22、d and upper-middle-class parents turn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on.M Although
23、Leslies book isnt about politics, he doesnt entirely shy away from the problem. Political leaders, like leaders of other organizations, should be curious. They should ask questions at crucial moments. There are serious consequences, he warns, in not wanting to know.N He presents as an example the fa
24、ilure of the George W. Bush administration to prepare properly for the after-effects of the invasion of Iraq. According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the “unknown unknowns” were mistaken. Rumsfelds idea, Leslie
25、writes, “wasnt absurd一it was smart.” He adds, “The tragedy is that he didnt follow his own advice.”O All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples is charging, in a different way, that someone in authority is intentionally being incurious. I
26、 leave it to the readers political preference to decide which, if any, charges should stick. But lets be careful about demanding curiosity about the other sides weaknesses and remaining determinedly incurious about our own. We should be delighted to pursue knowledge for its own sakeeven when what we
27、 find out is something we didnt particularly want to know.36. To be curious, we need to realize first of all that there are many things we dont know.37. According to Leslie, curiosity is essential to ones success.38. We should feel happy when we pursue knowledge for knowledges sake.39. Political lea
28、ders lack of curiosity will result in bad consequences.40. There are often accusations about politicians and the medias lack of curiosity to find out the truth.41. The less curious a child is, the less knowledge the child may turn out to have.42. It is widely accepted that academic accomplishment li
29、es in both intelligence and diligence.43. Visiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44. Both the rise of the Internet and reduced appetite for literary fiction contribute to peoples declining curiosity.45. Mankind wouldnt be so innovative without curiosity.Se
30、ction CPassage OneAging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease.”On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk
31、factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that desc
32、ribing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical (制药的)industry so that they can begin treating the disease and not just the side effects,” he said.Right now, people think of aging as natural and something you cant control: he said. “In academic circles, people take aging research as just an interest area
