Academic dishonesty is nothing new. As long as there have been homework assignments and tests, there have been cheaters. The way that cheating looks has changed over time, though, particularly now that technology has made it easier than ever. A study by the Josephson Institute of Ethics interviewed 23,000 high school students and asked them a variety of questions about academic ethics. Of the teens surveyed, 51 percent said that they had knowingly cheated at some point on an exam but that they did not feel uneasy about the behaviour. A Common Sense Media survey found that 35 percent of students had cheated via smartphone, though the parents surveyed in that particular study did not believe their kids had ever cheated. In many cases, students did not realize that strategies like looking up answers on a smartphone were actually cheating at all. What did the Common Sense Media survey reveal? A. Most parents tended to overprotect their children.B. Many students committed cheating unknowingly.C. Students were in urgent need of ethical education.D. Parents and kids had conflicting ideas over cheating.

Academic dishonesty is nothing new. As long as there have been homework assignments and tests, there have been cheaters. The way that cheating looks has changed over time, though, particularly now that technology has made it easier than ever.

A Common Sense Media survey found that 35 percent of students had cheated via smartphone, though the parents surveyed in that particular study did not believe their kids had ever cheated. In many cases, students did not realize that strategies like looking up answers on a smartphone were actually cheating at all.In today’s classrooms, students who cheat are rarely caught. There are no formulas written on the insides of hands or students looking across the aisle, or whispering answers to their classmates. Today’s students use smartphones, tablets or even in-class computers to aid their cheating attempts and leave no trace of their crimes. Since cheating through technology is not listed specifically as being against the rules in many school policies, students do not view the actions unethical (不合道德的).The technology is being adopted so quickly that school districts cannot adequately keep up with cheating policies, or even awareness campaigns that alert students to the problem with using technology to find answers in a certain way. From a young age, students learn that answers exist conveniently at their fingertips through search engines and expert websites.Schools must develop anti-cheating policies that include technology and these policies must be updated consistently. Teachers must stay on guard when it comes to what their students are doing in classrooms and how technology could be playing a negative role in the learning process. Parents must also talk to their kids about the appropriate ways to find academic answers and alert them to unethical behaviours that may seem innocent in their own eyes.1. What do we learn from the study by the Josephson Institute of Ethics?A. Over half of the students interviewed were unaware they were cheating.B. Cheating was becoming a way of life for a majority of high school teens.C. Cheating was getting more and more difficult for high school students.D. More than half of the interviewees felt no sense of guilt over cheating.2. What did the Common Sense Media survey reveal?A. Most parents tended to overprotect their children.B. Parents and kids had conflicting ideas over cheating.C. Students were in urgent need of ethical education.D. Many students committed cheating without parents’ awareness.3. What does the author think schools should do to tackle cheating?A. Alert parents to their children’s behaviour.B. Reform their exam methods constantly.C. Take advantage of the latest technologies.D. Bring policies against cheating up to date.4. What does the author suggest teachers do in the classroom?A. Prevent students from using electronic devices.B. Develop more effective anti-cheating strategies.C. Guard against students’ misuse of technologyD. Find more ways to stop students’ unethical acts.

Obama's Success Isn't All Good News for Black Americans As Erin White watched the election results head towards victory for Barack Obama, she felt a burden lifting from her shoulders. "In that one second, it was a validation for my whole race," she recalls. "I've always been an achiever," says White, who is studying for an MBA at Vanderbilt University in Nashville, Tennessee. "But there had always been these things in the back of my mind questioning whether I really can be who I want. It was like a shadow, following me around saying you can only go so far. Now it's like a barrier has been let down. " White's experience is what many psychologists had expected—that Obama would prove to be a powerful role model for African Americans. Some hoped his rise to prominence would have a big impact on white Americans, too, challenging those who still harbour racist sentiments. "The traits that characterise him are very contradictory to the racial stereotypes that black people are aggressive and uneducated," says Ashby Plant of Florida State University. "He's very intelligent and eloquent." Sting in the Tail Ashby Plant is one of a number of psychologists who seized on Obama's candidacy to test hypotheses about the power of role models. Their work is already starting to reveal how the "Obama effect" is changing people's views and behaviour. Perhaps surprisingly, it is not all good news: there is a sting in the tail of the Obama effect. But first the good news， Barack Obama really is a positive role model for African Americans, and he was making an impact even before he got to the White House. Indeed, the Obama effect can be surprisingly immediate and powerful, as Ray Friedman of Vanderbilt University and his colleagues discovered. They tested four separate groups at four key stages of Obama's presidential campaign. Each group consisted of around 120 adults of similar age and education, and the test assessed their language skills. At two of these stages, when Obama's success was less than certain, the tests showed a clear difference between the scores of the white and black participants—an average of 12. 1 out of 20, compared to 8.8, for example. When the Obama fever was at its height, however, the black participants performed much better. Those who had watched Obama's acceptance speech as the Democrats' presidential candidate performed just as well, on average, as the white subjects. After his election victory, this was true of all the black participants. Dramatic Shift What can explain this dramatic shift？ At the start of the test, the participants had to declare their race and were told their results would be used to assess their strengths and weaknesses. This should have primed the subjects with "stereotype threat"—an anxiety that their results will confirm negative stereotypes, which has been shown to damage the performance of African Americans. Obama's successes seemed to act as a shield against this. "We suspect they felt inspired and energised by his victory, so the stereotype threat wouldn't prove a distraction," says Friedman. Lingering Racism If the Obama effect is positive for African Americans, how is it affecting their white compatriots (同胞 ) ？ Is the experience of having a charismatic (有魅力的 ) black president modifying lingering racist attitudes？ There is no easy way to measure racism directly; instead psychologists assess what is known as "implicit bias", using a computer-based test that measures how quickly people associate positive and negative words—such as "love" or "evil"—with photos of black or white faces. A similar test can also measure how quickly subjects associate stereotypical traits—such as athletic skills or mental ability—with a particular group. In a study that will appear in the Journal of Experimental Social Psychology, Plant's team tested 229 students during the height of the Obama f A．Excited. B．Victorious. C．Anxious. D．Relieved.
