22、情并没有什么效果，work“奏效，起作用”。2B根据语境可知，空处上下句之间存在逻辑上的转折关系，even though“即使，尽管”，符合语境。3A根据下文中的“Many people believe that they can _4_ two or more tasks at the same time”可知，孩子们会声称能同时做十件事情。at once“一起，同时”。4C根据语境可知，许多人相信他们可以同时做两件或是更多事情。perform“做，执行，履行”。5A根据下文中的“poor job performance”可知，Dr. Edward Hallowell认为同时做多个任务是不可

23、能的。故A项正确。6A根据语境尤其是“poor job performance”可推知，同时做多项任务的结果很不好。result in“导致，造成”。7C根据空后的“smartphones, iPads”可知，此处表示新的便携式装备，故C项正确。下文13空后的“handheld devices”也是信息提示。8D根据下文中的“leading to difficulty focusing on the task”可推知，多任务容易分散注意力。share“共享，共用”。9A根据空后的“such as listening in the classroom or doing homework”可知，这

24、些都是手头要做的事。at hand“在手边”。10B根据第一段最后两句可知，Dr. Edward Hallowell并不赞成多任务行为，因此当大脑给这种行为以肯定或鼓励时，他认为是不幸的。11B根据空后的“even though”可知，空处与worse形成对比，由此可推知大脑反而鼓励这种多任务行为。reward“奖赏，报答”。12D根据上文中的“gets worse and worse”和空后的“because they feel better when they multitask”可知，孩子们并不知道自己变得更糟糕。13A结合空后现在完成时的运用可知，此处应用连词since“自从之后”引导

25、状语从句。14D根据上文的“teachers”可推知，老师们注意到学生们在学业上的差异。academic“学术的”。15B根据下文中的“Multitasking prevents people from gaining a deep understanding of the information they are trying to learn”可知，这些便携式工具的出现改变了学生处理信息的方式。process“处理”。16A根据空前的“Kids have a difficult time sticking with a difficult to understand topic”可知，孩子

26、们很难坚持一个理解起来有困难的话题，他们的注意力往往会分散。tend to do sth.“往往会做某事”。17D根据语境可知，既然注意力分散了，孩子们就有可能转而关注学习之外的东西。switch over to“转向”。18B根据语境可知，孩子们去玩手机或Facebook，而不是更努力地学习。rather than“而不是”。19Ain the long run为固定短语，意为“从长远来看”，符合语境。20C根据空后的“resulting in lower grades”可知，在课堂上上网的孩子考试成绩差。四、单句改错1A disadvantage of copying others hom
