Unit 4 Making the news导读：如果你在准备考试或是在工作，请扯掉你的 iPod 耳机、关掉收音机！最新调查研究发现，当你专心进行脑力劳动时，背景音乐(background music)会扰乱且伤害你的记忆能力。Task：Do you know it is not good for you to listen to music while studying？ A new research has found that studying for an exam while listening to music is not smart, because background music can impair your ability to perform memory tasks. The participants' recall ability is poorest when listening to music, regardless of whether they like or dislike it, the research shows. The poorer performance of the music and changing － state sounds are due to the acoustical variation within those environments. This impairs the ability to recall theorder of items, via rehearsal, within the presented list. Mental arithmetic also requires the ability to retain order information in the short － term via rehearsal, and may be similarly affected by their performance in the presence of changing － state, background environments. So when performing a challenging mental task, do it in silence. (124 words) 请根据语义及提示写出单词 1. This book demanded all your __________. (concentrate) 2.
