Question

19．Welcome to the world of multitasking-a place where the measure of a person is how many jobs they can perform at the same time．In fact，if experts are to be believed，multitasking is a disastrous idea．
One of the opponents of multitasking is Dr．Clifford Nass，a professor at Stanford University．"People who multitask frequently are less able to pay attention； they're worse at managing their memory．"he said．In his opinion，the loss that we get with multitasking is harmless in some situations，for example，part of doing business in the digital world：but you can't do serious work like writing，thinking or solving an important problem this way．You do worse even as you think you're doing better．All the time the research points to a simple fact：the brain cannot cope．When you stop midway through composing a report to check an email，you force your brain to stop and regroup．It is like pressing the pause button during a movie，meaning the film takes longer to watch．
And as for Dr．Nass，the problems extend beyond the brain．Young people who frequently multitask are not as socially and emotionally healthy as those who don't．They just feel more emotionally satisfied and the feeling is so good and they are bound to desire it again．Todd Oppenheimer，a writer said"We've become a very short-term society and don't reward people for taking a lot of time on something．"He fears we may end up losing the next generation of great thinkers．"It's really unfortunate because the long-term challenges of our world-environmental issues，financial issues-require people to think wisely about the long-term consequences of what they do．And it's no coincidence that the kind of people who do think long-term don't multitask．"

Answer 1

分析 这是一篇科普文．研究人员发现，同时做很多事情的人做事不专一，不仅会导致事倍功半，而且还会影响人们的社交与情感健康．

解答 29-32 DBCA
29 D 细节理解题．根据for example，part of doing business in the digital world：but you can't do serious work like writing，thinking or solving an important problem this way．比如在数字化的世界里做生意（doing business in the digital world）是无害的，因此选D．文章说同时做很多事会影响我们在人际交往和情感方面的健康（A错），会使我们记性更差（B错），一位叫Todd的作家说这样可能会使我们失去未来一代伟大的思想家（C错）．
30 B 推理判断题．根据Welcome to the world of multitasking-a place where the measure of a person is how many jobs they can perform at the same time．In fact，if experts are to be believed，multitasking is a disastrous idea．欢迎来到同时做很多事的世界，在这里，对一个人的衡量标准是他能同时开展多少项工作，这个想法实际上害人不浅，因此B项正确；从第二段可知A、C错，因为multitasking有时是无害的，有时则会妨碍我们；第二段最后一句通过打比方的方式告诉我们，这样会使事情做得更慢（D错）．
31 C 推理判断题．从本题四个选项的陈述看，A、B、D都是专心在做一件事，C项说办公桌上放着各种没有完工的项目的文书工作，这里的various unfinished projects属于multitasking．故选C．
32 A 主旨大意题．全文通过斯坦福大学一位教授的话告诉我们，同时做很多事不仅不能提高工作效率，反而对我们的健康不利，因此A项"角色转换越少，做的就越好"是本文的主题．故选A．

点评 本文是政治经济类阅读理解．做这类题材阅读理解时要求考生对文章通读一遍，做题时结合原文和题目有针对性的找出相关语句进行仔细分析，结合选项选出正确答案．推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案，切忌胡乱猜测，一定要做到有理有据．
