New research on college students suggests that the mere presence of a cell phone can impair(损害)learning during a lecture. The study, published in the journalComputers in Human Behavior, found cell phones tended to reduce attention and memory – even when they weren’t used.“This topic interests me for a couple of different reasons,” said Ian M. McDonough, an Assistant Professor at the University of Alabama and the corresponding author of the study.“While the previousresearch has suggested that technology generally impairs learning if not used directly for learning-related activities, cell phones and laptops are likely just going to become more frequent in the classroom. Thus, we need to understand the factors that impact learning in the presence of technology rather than to forcibly take away students’ technology.”For their experiment, the researchers had 381 college students watch a videotaped lecture and take a short quiz about it afterward. Some of the students were allowed to use their cell phones, some were told not to use it and to put it into silent mode, and some were not allowed to possess a cell phone at all. In addition, four text messages were sent toallthe participants during the lecture. The researchers found that students tended to perform worse on the quiz when they had their cell phones. The same was true of students who were noticeably distracted by the texts.“In addition, people’s own emotional state, such as the need to feel connected to others via their mobile device, has a reliable and negative impact on attention and learning. Thus, teachers and students alike need to work together to find solutions to enhance learning without sacrificing one’s learning ability and emotional health. This problem will not be easy to fix, especially as students become more emotionally reliant on their cell phones or other mobile devices.”(1) (单选题)1.What did the study published inComputers in Human Behaviorfind?A.Most college students rely heavily on their cell phones.B.Merely having a cell phone with you may affect learning.C.The addiction to cell phones influences students’ health.D.Cell phones can improve one’s memory if used properly.(2) (单选题)What did the previous study suggest according to Ian M.
