Passage 3 The advent of computers has brought with it a new set of opportunities for mischief (危害) and crime. Today, computers are easy to come by and many people know how computer technology works. More importantly, the growing use of computer networks can multiply a breach (破坏) of security, making larger numbers of people more vulnerable(脆弱的) than would be the case if they were using single, stand-alone computers.

The U.S. Defense Advanced Research Project Agency has requested that the Research Council’s(委员会) Computer Science and Technology Board assess(评定) the security problems posed by computer technology, see what solutions may already exist, review research efforts aimed at avoiding security problem in the future, and evaluate existing policies relevant to computer security. The study committee will examine the issue of security for a broad spectrum of users, including the business, national security, and academic communities, as well as the general public. David D.Clark, senior research scientist, Laboratory for Computer Science, Massachusetts Institute of Technology, will chair the committee of experts in electronic security, net work security, computer law, software engineering, cryptography(密码编制), and operating systems. The committee will also include computer users from the defense and banking industries.Which of the following is most likely to be agreed by computer experts A．Computers are easily available.B．There are many kinds of computer security problems.C．Computer viruses are the only problem facing the computer network.D．The growing use of computer networks can multiply a breach of security.

British Prime Minister Boris Johnson recently unveiled a “Better Health” campaign to combat obesity. His proposed interventions include banning junk food advertising before 9 P.M. to reduce the likelihood that children would be exposed to such ads, preventing stores from selling unhealthy snacks at entrances and checkouts, barring “buy one get one free” promotions on unhealthy foods. Critics of Johnson’s anti-obesity measures rightly charge that they are incomplete because they focus on personal responsibility rather than attacking the root causes of obesity—poverty and inequality. Weight is a delicate issue, and mishandling “wars” on fat or obesity could impair, rather than improve, the physical and mental health of people with obesity. Public health initiatives must learn from the mistakes of previous campaigns that regarded people with obesity as lazy, weak-willed and gluttons for junk food. In a controversial ad campaign, one Georgia poster featured four overweight children, with captions such as, “Big bones didn’t make me this way. Big meals did.” This type of misguided ads and anti-obesity campaigns will stress the notion that people with obesity are social and medical burden. Overweight children may be subjected to more bullying by peers if there are internet ads, posters and billboards stigmatizing people with obesity and their alleged diet and exercise habits. To those who insist that blunt messaging is necessary to underscore the gravity of obesity just as sensationalistic anti-tobacco ads were needed to drive home the dangers of smoking, public health research has shown that not only is stigmatization ineffective, it can induce people with obesity to gain rather than shed, pounds. Studies have found that both children and adults subjected to weight-based bullying or discrimination are more likely to seek comfort in binge-eating, to develop eating disorders and to be discouraged from exercise due to anxieties about their bodies being on display. To avoid these consequences, campaigns to reduce obesity should focus on the positive aspects of maintaining healthy diet and exercise habits. And because lower-income Americans are more likely to live in neighborhoods with comparatively fewer supermarkets and green spaces, public policy interventions should also ensure access to affordable healthy foods and spaces that facilitate exercise and recreation. Such interventions align with the consensus among obesity experts that weight is the function of the interaction between genes and the environment. Finally, it is imperative that anti-obesity initiatives also include an educational component in which the public and even health care providers are informed about the effects of weight bias.According to the first paragraph, Boris Johnson campaigns to .A. decease the production of junk foodB. crack down on deceptive advertisingC. make English children go to bed earlyD. help British people fight overweight
