Question

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (尋求刺激) or imperative (沖動) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”
【小題1】The research led by Sanbonmatsu indicates that people who multitask __________.

A．seek high productivity constantly

B．prefer handling different things when getting bored

C．a(chǎn)re more focused when doing many things at a time

D．have the poorest results in doing various things at the same time

【小題2】When Sanbonmatsu and his colleagues conducted their research, they __________.

A．a(chǎn)ssessed the multitasking ability of the students

B．evaluated the academic achievements of the students

C．a(chǎn)nalyzed the effects of the participants’ tricky mental tasks

D．measured the changes of the students’ understanding ability

D．impulsive desire to try new things

【小題4】From the last paragraph, we can learn that multitaskers usually __________.

Answer 1

【小題1】D
【小題2】A
【小題3】C
【小題4】C

解析試題分析：中國有句古語云：一心不可二用。而最近的一項研究就表明。那些經(jīng)常一心多用的人往往就是同時做兩件事做的最糟糕的人。正是因為不能專注于一件事，才會同時多做幾件事，結(jié)果可想而知。
【小題1】細(xì)節(jié)理解題。根據(jù)全文第一句話可知，一心多用，往往會把事情做得更糟糕。故選D。
【小題2】細(xì)節(jié)理解題。根據(jù)第二段最后一句話可知，然后他們要這些學(xué)生一面做一些數(shù)學(xué)運算, 一面記憶一組字母, 用這個很刁難的方法來測試這些學(xué)生一心多用的能力。和A項意思一致 。
【小題3】細(xì)節(jié)理解題。根據(jù)全文第二句的but because they are easily distracted (分心) and can’t focus on one activity.可知，許多人一心多用, 并不是因為他們想要增強(qiáng)工作生產(chǎn)量, 而是因為他們很容易分心或是不能專注于做一件事。故選C。
【小題4】推理判斷題。由最后一段的People who are multitasking are generally less sensitive to risky situations.一心多用的人一般對危險的情形不太敏感�？芍�，對危險的事情，一心多用者往往對潛在的危險不能迅速判斷。故選C。
