　　【试题】

　　In a recent study carried out by psychologists on the disruptive effects of smart phones, [22] two groups of college students were given word-search puzzles. The first group was told to complete the puzzles with its participants' smart phones in their line of sight. The second group, however, was told that the phones would interfere with the equipment in the experiment and would need be moved away from the testing area. Midway through the second group's solving of the puzzles, the experiment called one of the phones and let it ring for a while before hanging up. [23] Many of the students in that group were unable to focus from then on, becoming anxious and performing more poorly than the first group.

　　Use of electronics has also been known to lead to a decline in human interactions. Rather than having real-life conversations, many express emotions and engage in deep conversations through social media sites. Many students use their phones and computers during class for non-academic activities, which leads to poor grades. [24] Perhaps the most dramatic impact is the reduction in amount of sleep, which lead to poor health and weight gain.

　　Technology is a great tool. [25] However, it's important to recognize its downsides. Lack of sleep, reduction of productivity, and weight gain are only a few. If we are not careful about all these mind problems right now, the effect on the future generation is going to be much bigger.

　　Questions 22 to 25 are based on the passage you have just heard.

　　Q22. What were the college students in both groups require to do in the study?

　　Q23. What do we learn about many of the students in the second test group after the phone ring?

　　Q24. According to the passage, what is the most dramatic impact of smart phone use?

　　Q25. what does the speaker suggest people do?

　　【答案】

　　(见上文划线部分)

　　【解析】

　　Q22. 根据关键词“both groups”可定位至文章开头，可以听到“Two groups of college students were given word search puzzles”，即两组大学生参加了单词搜索谜题游戏。第一组可以使用智能手机，第二组被告知会在过程中用手机进行干扰。于是可知两组学生都需要在实验中中完成的是“word search puzzles”.

　　Q23. 根据关键词“the second test group”可知题干问的是第二组学生的表现，划线句提到“许多学生无法集中精力，且比第一组学生更焦虑且表现更差”。

　　Q24. 根据关键词“the most dramatic impact”可定位至划线句，原文提到“也许最显著的影响是睡眠的减少，这会导致健康状况不佳和体重增加。”

　　Q25. 题干问的是对人们的建议。根据题文同序原则，文中最后提到“认识到技术的缺点是很重要的…如果我们现在不注意这些思维问题，对未来一代的影响将会更大”

　　【听力述评】

　　本文是一个典型的实验分析型文章，原文通过对两组实验进行对比得出结果和分析，题目中分别对不同组别的表现进行提问，均可通过关键词“both groups, second group”获取定位信息。类似文章的结尾会出现对实验结果的分析并以小见大，本文均做出考查，考生需识别题干关键词“dramatic”并总结文中后三句的内容。最后一题难度稍大。
