A Bad Idea
Think you can walk, drive, take phone calls, e-mail and listen to music at the same time? Well,New York's new law says you can't. 46 The law went into force last month, followingresearch and a shocking number of accidents that involved people using electronic gadgets (机械装置) when crossing the street.
Who's to blame? 47 "We are under the impression that our brain can do more than it
often can," says Rene Marois, a neuroscientist (神经科学家)in Tennessee. "But a core limitation isthe inability to concentrate on two things at once".
The young people are often considered the great multi-taskers. 48 A group of 18-to21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate images intonumbers, using a simple code. 49 But when both groups were interrupted by a phone call oran instant message, the older group matched the younger group in speed and accuracy.
It is difficult to measure the productivity lost by multi-taskers. But it is probably a lot. JonathanSpire, chief analyst at Basex, a business-research firm, estimates the cost of interruptions to theAmerican economy at nearly $650 billion a year. 50 The surveys conclude that 28 percent of theworkers' time was spent on interruptions and recovery time before they returned to their main tasks.
A. And you'll be fined $100 if you do so on a New York City street.
B. Talking on a cell-phone while driving brings you joy anyway.
C. The estimate is based on surveys with office workers.
D. The younger group did 10 percent better when not interrupted.
E. However, Oxford University research suggests this perception is open to question.
F. Scientists say that our multi-tasking (多任务处理) abilities are limited.
第5部分：补全短文
46.A。空白处的前一句讲美国法律不允许你在走路、开车、打电话或是发邮件的时候听音乐。而空白处后一句讲这个法律是上月生效的。因此A选项(如果在纽约街头这样做的话，你会被罚款1000美元)符合语境，所以A选项正确。
47.F。空白处的前一句问该责备谁呢，空白处后一句讲“我们现在的印象是我们的大脑能做的事情比平时多”。因此F选项(科学家说多任务处理的能力是很有限的)正确。
48.E。空白处的前一句讲年轻人通常被认为能够进行多任务处理。空白处的后一句讲述了一个年龄在18——21岁的.组和一个年龄在35——39岁的组分别给予90秒钟的时间，运用一种简单的解码将图片转化成数字。因此E(但是，哈佛大学的研究认为这个观点是有问题的)为正确选项。
49.D。空白处的前一句讲一个年龄在18——21岁的组和一个年龄在35——39岁的组分别给予90秒钟的时间运用一种简单的解码将图片转化成数字。空白处的后一句讲，当两个组被一个电话或短信打断时，两组的反应速度和准确率还是相当的。因此D选项(年轻那组在不被打断的情况下能做到多10%的业绩)符合语境，所以D选项正确。
50.C。空白处前一句主要讲Jonathan Spire估计因为被打断而对美国经济造成的损失为每年将近6500亿美元。空白处后一句讲这个调查认为工人工作时间的28%用在被打断和恢复工作上。所以选项C(这个估算是根据办公室人员的调查得来的)为正确选项。
