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.

        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 as unethical.

        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.

解析：D。根据题干中的rarely get caught可定位至原文第二段第一句。该句提到了一个现象，即如今作弊的学生很少会被抓住，并在之后解释了原因：没人会在手心里写公式，没有学生会隔着过道偷看，或是小声告诉答案。如今的学生们会使用智能手机、平板电脑，甚至是教室里的电脑来辅助他们作弊，而且不会留下任何作弊的痕迹。由此可知，由于学生使用了技术，不容易留下作弊痕迹，所以很少会被抓住。D项是对原文第二段第三句的概括总结，故为正确答案。

错项排除：原文中说的是如今学生们不会在手心里写公式，A项与此相悖，故排除。B项和C项在原文中无依据，故均可排除。
