For many of us, while we are reading something, we may be listening to music or the radio at the same time. For people who work online, they may be used to e-mailing or instant-messaging or checking stocks at the same time. Since the 1990s, we have accepted multitasking without question. ___39___ While multitasking may seem to be saving time, psychologists and neuroscientists are finding that it can put us under a great deal of stress and actually make us less efficient. Basically, multitasking is shifting focus from one task to another in rapid succession. ___40___ It gives the illusion that we are simultaneously tasking, but we are really not. In plain language, it is like playing tennis with three balls.
Of course, it depends what we are doing. For some people, listening to music while working actually makes them more creative because they are using different cognitive functions. ___41___ We may all be familiar with the so-called “e-mail voice,” when someone we are talking to on the phone suddenly sounds, well, disengaged. ___42___ They point out that it is a
big illusion that people think they can shift back and forth between tasks.

(B)But the researchers say that many of us do not like, or even hate, to do many things in a short period of time at work.
(C)Virtually all of us spend part or most of our day either rapidly switching from one task to another or juggling two or
more things at the same time.
(D)Although doing many things at the same time can be a way of making tasks more fun and energizing, we have to keep
in mind that we sacrifice focus when we do this.
