2020屆高考英語(yǔ)閱讀理解之主旨大意題復(fù)習(xí)
in order to multitask, the brain uses an area known as the prefrontal cortex (前額葉腦皮層). brian scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. you may have experienced a prefrontal cortex “moment of rest” yourself if you’ve ever dialed (撥電話) a phone number and suddenly forgotten who you dialed when the line is answered. what probably occurred is that between the dialing and the answering, your mind shifted to anther thought or task, and then took that “moment” to come back. research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time. k*s5u
multitasking is easiest when at least one of the tasks is habitual, or requires little thought. most people don’t find it difficult to eat and read the newspaper at the same time. however, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.
we often don’t remember things as well when we’re trying to manage several details at the same time. without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. that is one of the main reasons we forget people’s names---even sometimes right after they have introduced themselves. multitasking can also affect our relationships. if someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. it can also cause that person to miss or overlook key information being passed on to them.
52. what is the main idea of the passage?
a. multitasking has become a way of life.
b. multitasking often leads to efficiency decline.
c. multitasking exercises need to be improved.
d. multitasking enables people to remember things better.
答案：b
解析：主旨大意題。最后一段中作者繼續(xù)描述了之前的觀點(diǎn)：一個(gè)人同時(shí)從事多項(xiàng)工作會(huì)出現(xiàn)很多問題。回到整篇文章，作者主要觀點(diǎn)就是告訴大家：多項(xiàng)工作不能產(chǎn)生高效的結(jié)果，故選擇b。k*s5u
