1、A small group of Internet security specialists gathered in Singapore to start up a Global system to make e-mail and e-commerce more secure, end the rapid growth of passwords and raise the bar significantly for Internet fraud, spies and troublemakers.The Singapore event included an elaborate technical ceremony to create and then securely store numerical keys that will be kept in three hardened data centers there, in Zurich and in San Jose, Calif. The keys and data centers are working parts of a technology known as Secure DNS, or DNSSEC. DNS refers to the Domain Name System, which is a directory that connects names to numerical Internet addresses. Preliminary work on the security system had been going on for more than a year, but this was the first time the system went into operation, even though it is not quite complete.The three centers are fortresses made up of five layers of physical, electronic and cryptographic security, making it virtually impossible to damage the system. Four layers are active now. The fifth, a physical barrier, is being built inside the data center.The technology is viewed by many computer security specialists as a ray of hope amid the recent cascade of data thefts, attacks, disruptions and scandals, including break-ins at Citibank, Sony, Lockheed Martin, RSA Security and elsewhere. It allows users to communicate via the Internet with high confidence that the identity of the person or organization they are communicating with is not being tricked or forged.Internet engineers like Dan Kaminsky, an independent network security researcher who is one of the engineers involved in the project, want to counteract three major deficiencies in today’s Internet. There is no mechanism for ensuring trust, the quality of software is uneven, and it is difficult to track down bad actors.One reason for these flaws is that from the 1960s through the 1980s the engineers who designed the network’s underlying technology were concerned about reliable, rather than secure, communications. That is starting to change with the introduction of Secure DNS by governments and other organizations.The event in Singapore capped a process that began more than a year ago and is expected to be complete after 300 so-called top-level domains have been digitally signed. Before the Singapore event, 70 countries had adopted the technology, and 14 more were added as part of the event. While large countries are generally doing the technical work to include their own domains in the system, the association of Internet security specialists is helping smaller countries and organizations with the process.1.It is indicated in Paragraphs 1 and 2 that the Singapore event intended to____.2.It is suggested in Paragraph 4 that___.3.The word “counteract”(Line 2, Paragraph 5) is closest in meaning to___.4.Which of the following is true according to the last paragraph?5.What would be the best title for the text?

2、When older people can no longer remember names at a cocktail party, they tend to think that their brainpower is declining. But more and more studies suggest that this assumption is often wrong. Instead, the research finds, the aging brain is simply taking in more data and trying to sift through a clutter of information, often to its long-term benefit. The studies are analyzed in a new edition of a neurology book, “Progress in Brain Research.”Some brains do deteriorate with age. Alzheimer’s disease, for example, strikes 13 percent of Americans 65 and older. But for most aging adults, the authors say, much of what occurs is a gradually widening focus of attention that makes it more difficult to latch onto just one fact, like a name or a telephone number. Although that can be frustrating, it is often useful. “It may be that distractibility is not, in fact, a bad thing,” said Shelley H. Carson, a psychology researcher at Harvard whose work was cited in the book. “It may increase the amount of information available to the conscious mind.”For example, in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases, adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean, older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling over the extra information, but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers, the older adults responded much better than the students.“For the young people, it’s as if the distraction never happened.” said an author of the review, Lynn Hasher, a professor of psychology at the University of Toronto and a senior scientist at the Rotman Research Institute. “But for older adults, because they’ve retained all this extra data, they’re now suddenly the better problem solvers. They can transfer the information they’ve soaked up from one situation to another.”In the real world, such tendencies can yield big advantages, where it is not always clear what information is important, or will become important. A seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes. Or extra details that stole your attention, like others’ yawning and fidgeting, may help you assess the speaker’s real impact.1.From the first two paragraphs, we learn that____2.Older adults tend to be forgetful because of____3.The studies mentioned in paragraph 3 show that____4.What can we infer from the last paragraph?5.The text intends to tell us that____

3、Text 1 People often complain that plastics are too durable. Water bottles, shopping bags, and other trash litter the planet, from Mount Everest to the Mariana Trench, because plastics are everywhere and don't break down easily. But some plastic materials change over time. They crack and frizzle. They "weep" out additives. They melt into sludge. All of which creates huge headaches for institutions, such as museums, trying to preserve culturally important objects. The variety of plastic objects at risk is dizzying: early radios, avant-garde sculptures, celluloid animation stills from Disney films, the first artificial heart. Certain artifacts are especially vulnerable because some pioneers in plastic art didn't always know how to mix ingredients properly, says Thea van Oosten, a polymer chemist who, until retiring a few years ago, worked for decades at the Cultural Heritage Agency of the Netherlands. "It's like baking a cake: If you don't have exact amounts, it goes wrong;' she says. "The object you make is already a time bomb." And sometimes, it's not the artist's fault. In the 1960s, the Italian artist Picro Gilardi began to create hundreds of bright, colorful foam pieces. Those pieces included small beds of roses and other items as well as a few dozen "nature carpets" - large rectangles decorated with foam pumpkins, cabbages, and watermelons. He wanted viewers to walk around on the carpets - which meant they had to be durable. So van Oosten and her colleagues worked to preserve Gilardfs sculptures. They infused some with stabilizing and consolidating chemicals. Van Oosten calls those chemicals "sunscreens" because their goal was to prevent further light damage and rebuild worn polymer fibers. She is proud that several sculptures have even gone on display again, albeit sometimes beneath protective cases. Despite success stories like van Oosten's, preservation of plastics will likely get harder. Old objects continue to deteriorate. Worse, biodegradable plastics designed to disintegrate, are increasingly common. And more is at stake here than individual objects. Joana Lia Ferreira, an assistant professor of conservation and restoration at the NOVA School of Science and Technology, notes that archaeologists first defined the great material ages of human history - Stone Age, Iron Age, and so on - after examining artifacts in museums. We now live in an age of plastic, she says, "and what we decide to collect today, what we decide to preserve ... will have a strong impact on how in the future we'll be seen. 1、According to Paragraph 1, museums are faced with difficulties in________.2、Van Oosten believes that certain plastic objects are________.3、Museums stopped exhibiting some of Gilardi's artworks to________.4、The author thinks that preservation of plastics is________.5、In Ferreira's opinion, preservation of plastic artifacts________.

4、Text 3 ①As a historian, who’s always searching for the text or the image that makes us re-evaluate the past., I’ve become preoccupied with looking for photographs that show our Victorian ancestors smiling (what better way to shatter the image of 19th-century prudery?). ②I’ve found quite a few, and—since I started posting them on Twitter—they have been causing quite a stir. ③People have been surprised to see evidence that Victorians had fun and could, and did, laugh. ④They are noting that the Victorians suddenly seem to become more human as the hundred-or-so years that separate us fade away through our common experience oflaughter. ①Of course, I need to concede that my collection of “Smiling Victorians” makes up only a tiny percentage of the vast catalogue of photographic portraiture created between 1840 and 1900, the majority of which show sitters posing miserably and stiffly in front of painted backdrops, or staring absently into the middle distance. ②How do we explain this trend? ①During the 1840s and 1850s, in the early days of photography, exposure times were notoriously long: the daguerreotype photographic method (producing an image on a silvered copper plate) could take several minutes to complete, resulting in blurred images as sitters shifted position or adjusted their limbs. ②The thought ofholding afixedgrin as the camera performed its magical duties was too much to contemplate, and so a non-committal blank stare became the  norm. ①But exposure times were much quicker by the 1880s, and the introduction of the Box Brownie and other portable cameras meant that, though slow by today’s digital standards, the exposure was almost instantaneous. ②Spontaneous smiles were relatively easy to capture by the 1890s, so we mustlookelsewhere for an explanation of whyVictorians stillhesitatedtosmile. ①One explanation might be the loss of dignity displayed through a cheesy grin. ②“Nature gave us lips to conceal our teeth,” ran one popular Victorian maxim, alluding to the fact that before the birth of proper dentistry, mouths were often in a shocking state of hygiene. ③A flashing set of healthy and clean, regular “pearly whites” was a rare sight in Victorian society, the preserve of the super-rich (and even then, dental hygiene was notguaranteed). ①A toothy  grin (especially when there were gaps or blackened gnashers) lacked class: drunks, tramps, and music hall performers might gurn and grin with a smile as wide as Lewis Carroll’s gum-exposing Cheshire Cat, but it was not a becoming  look for properly bred persons.②Even Mark Twain,a man who enjoyed a hearty laugh, said that when it came to photographic portraits there could be "nothing more damning than a silly, foolish smile fixed forever". 1、According to Paragraph 1, the author ’ s  posts  on Twitter______. 2、What does the author say about the Victorian portraits he has collected? 3、What might have kept the Victorians from smiling for pictures in the 1890s? 4、Mark Twain is quoted to show that the disapproval of smiles in pictures was ______ . 5、Which of the following questions does the text  answer?

5、While still catching-up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. “Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men,” according to Dr. Yehuda, chief psychiatrist at New York’s Veteran’s Administration Hospital.    Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males.    Adding to a woman’s increased dose of stress chemicals, are her increased “opportunities” for stress. “It’s not necessarily that women don’t cope as well. It’s just that they have so much more to cope with,” says Dr. Yehuda. “Their capacity for tolerating stress may even be greater than men’s,” she observes, “it’s just that they’re dealing with so many more things that they become worn out from it more visibly and sooner.”    Dr. Yehuda notes another difference between the sexes. “I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating.”    Adeline Alvarez married at 18 and gave birth to a son, but was determined to finish college. “I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better.” Later, her marriage ended and she became a single mother. “It’s the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck.”    Not everyone experiences the kinds of severe chronic stresses Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarez’s experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.1、Which of the following is true according to the first two paragraphs?2、Dr. Yehuda’s research suggests that women _____.3、According to Paragraph 4, the stress women confront tends to be _____.4、The sentence “I lived from paycheck to paycheck.” (Line 6, Para. 5) shows that _____.5、Which of the following would be the best title for the text?
