Section C Passage 3

　　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.

　　篇章三是实验科普类文章，文章开头陈述实验：将大学生分成两组进行字谜游戏，一组的手机在视线范围内;另一组的手机被移出远离实验区域。实验过程中，实验人员拨打二组的其中一部电话，伴随着铃声响起，二组的参与者明显无法集中注意力并变得焦虑。根据该实验可得出的结论是，手机这类电子设备的使用对于人们的人际交往、学业成绩、身体健康都有不良影响。科技固然有好处，但是我们也应该认清它的缺陷并注意这些问题。

　　Q22: What were the college students in both groups required to do in the study?

　　答案：【D】To solve word search puzzles.

　　解析：文章第一句引入In a recent study，紧接着具体陈述了实验的内容，two groups of college students were given word-search puzzles，需要两组大学完成word-search puzzles, 选项动词与文章做同义转换，宾语名词部分保留原词，按照试听一致做选择即可。

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

　　答案：【A】They could no longer concentrate on their task.

　　解析：第23题难度较大，针对文章内容做了同义转换，本文要研究的是手机这类电子设备对于人们的不良影响，因此当第二组的实验参与者听到手机铃声却无法拿到手机时，Many of the students in that group were unable to focus from then on，许多学生难以集中注意力，原文中的unable to focus对应选项里的no longer concentrate。

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

　　答案：【D】A reduction in the amount of sleep.

　　解析：第24题文章中设置了【B】A decline in academic performance的陷阱选项，因为文章也同样列举了手机的使用对于学习成绩的影响：Perhaps the most dramatic impact is the reduction in amount of sleep, which lead to poor health and weight gain.。究其考点，关于智能电话对于人们的不良影响列举了很多条，最高级一定优先做答案，因此当听到文章出现最高级the most dramatic impact is the reduction in amount of sleep，可以不听问题直接选做答案。

　　Q25: What does the speaker suggest people do?

　　答案：【B】Realize the disruptive effects of technology.

　　解析：本道题目出现在转折词However之后做同义转换，However, it's important to recognize its downsides，最大的难点在于句中的recognize承认、认出以及downsides缺点，如果这两个单词不认识，很难选出正确答案。文中的意思是要意识到科技的缺点，对应【B】选项的要意识到科技的破坏性的影响。
