【文章內(nèi)容簡介】 form judgments about someone’s intelligence, confidence, and sincerity, and sunglasses keep us literally in the dark about forming those perceptions about a person. A recent study showed that people who wore sunglasses acted more selfishly and dishonestly than those wearing eyeglasses, which, the researchers argue, suggests that sunglasses cheat us into feeling more unknown. Sunglasses are a relatively modern everyday accessory. Sales started to pick up in the 1920s, but they didn’t bee monplace until about two decades after that. In their early days sunglasses were primarily used during risky water and snow sports, and were also associated with new technologies like airplane travel, which made them seem “daring and thoroughly modern”. Soon after that, Hollywood stars of the 1950s and 1960s started wearing sunglasses to defend themselves from being recognized by the public or harassed by paparazzi（狗仔隊） , whose flashbulbs would often explode violently, sometimes literally in their faces. But regardless of practicality, movie stars’ adoption of the sunglasses strengthened the link between sunglasses and attractiveness. 28. We know from Paragraph 1 that Vanessa Brown .

Then came the arrival of the Inter, and that changed everything. Before long, books were available on different sites on the web. It was only a matter of time until Kindle, Nook, and other ereaders swept the scene. Along with them came the ebook. Many believed that this would be the end of libraries. But libraries still exist today, and many of them even thrive(繁榮 ). So, how is it possible that they survived against the onslaught of ebooks? For one thing, the truth is that libraries were never just about borrowing books for free. Librarians provide many services other than those of a desk clerk or customer service agent. They often hold seminars, presentations, contests, and other events to promote free education. These events are considered necessary by parents and kids alike. For others, the library is a place where they can go to get away from the rush of the world and from social obligations or family troubles. Many go to the library to study for projects, papers and exams. Others simply see it as a recreational hobby. For another thing, most libraries and librarians do not reject the changing tides of technology. And neither does the world, for that matter. In the US, the graduate degree program to bee a librarian is often called a Library Science program. It reflects the fact that the country believes its librarians should keep up with the latest in information technology. Many librarians agree, and therefore have bee experts in the field. Librarians have by and large willingly educated themselves in the technology needed to keep up with the fastpaced digital world of technology today. So consider a visit to your local library to see all the recent changes. If you haven’t been to one in a while you might not recognize the place. But don’t worry. Your librarian will be happy to bring you up to speed. 32． Which of the following shows the structure of the text? A. B. C. D. CP: Central Point P: Point Sp: Subpoint(次要點 ) C: Conclusion 33.
