{{B}}The Science of Interruptions{{/B}}
In 2000, Gloria
Mark was hired as a professor at the University of California. She would arrive
at her desk in the morning, full of energy and ready to tackle her to-do list.
No sooner had she started one task than a colleague would e-mail her with an
urgent request; when she went to work on that, the phone would ring. At the end
of the day, Mark had accomplished a fraction of what she set out to
do.
Lots of people complain that office multitasking drives them
nuts. But Mark studies how high-tech devices affect our behavior, so she was
able to do more than complain: She set out to measure how nuts we’ve all become.

project before being interrupted. Each short project was itself fragmented into

[填空题]Today there is widespread agreement that multinational corporations will have an important effect on international relations and world economy. But there is little agreement on exactly what that effect will be. There are two groups of those who see them as benevolent and those who see them as evil.
Among those who see multinational corporations as benevolent, many emphasize their importance in helping reduce the gap between rich countries and poor ones. These business giants are referred to as "engines of development", because it is claimed that they do more to improve the economic life in less developed countries than all governmental foreign aid programs have ever done. By setting up factories abroad, they provide jobs; by equipping these factories with the latest machines and equipment, they make available the most modern technology. (41) . Multinational corporations today do not need their countries to provide military force to open foreign countries to their investmen
