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、The woman disappeared. She had been coming to our group therapy sessions for months, and suddenly she stopped. Other group members told me why: she had been beaten so badly by her husband that she ended up in the hospital. The assault happened while her husband was, to use a too dainty phrase, “under the influence” of alcohol. I wish this were an isolated incident, but alcohol is a common instigator of violence against others, as well as harm to oneself.This link between alcohol and violence has been shown in multiple countries. In 1998 the Bureau of Justice Statistics reported that in the U.S., two thirds of violent attacks on intimate partners occurred in the context of alcohol abuse. Drinking increases the perpetration of physical and sexual violence. Alcohol use also reportedly increases the severity of violent assaults. Although drinking alcohol does not always lead to violence and is not a prerequisite for violence to occur, the link between alcohol and violence is undeniable.The victims are overwhelmingly women. But children are also harmed. Parents who drink heavily are more likely to physically abuse their child. Youngsters who live in neighborhoods with more bars or liquor stores are more likely to be maltreated. In fact, one out of every 10 instances of child abuse reported to child protective service agencies in the U.S. involves alcohol use.Violent, drunken men fall victim, too. They are as likely to die from alcohol-related firearm incidents as drunk-driving accidents. For all the effort put into preventing drunk driving, we have utterly failed to appreciate that being intoxicated while in possession of a firearm is an equally dangerous situation. Nevertheless, many states permit customers to carry firearms into establishments that serve alcohol.As a mental health care provider, I also commonly see patients under the influence who contemplate or try suicide. Suicide attempts are often impulsive acts. When sober, many patients regret these efforts to take their own life. Unfortunately, alcohol intoxication increases the risk that people will attempt suicide with a firearm, and because guns are the most lethal suicide method in the U.S., it is often too late for regrets.How do we break this deadly connection? As doctors, we should always ask about alcohol use, violence and access to firearms, simply to raise awareness among our patients. But there is another strategy that would be highly effective: raise alcohol taxes. Yes, alcohol is taxed, but the taxes have not kept up with inflation, making drinking more affordable than it has been in decades. Evidence shows that driving the price up would lower drinking’s tragic human cost.1.According to Paragraph 1, the woman disappeared because____.2.The main idea of the second paragraph is to____.3.According to the author, the alcohol-related firearm incidents____.4.Suicide is mentioned in paragraph 5 to illustrate____.5.The author believes that we can break the connection by____.

3、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____
