1．If the house is ____ fire，_____ where is the nearest exit．（　�。�
A．in； findB．on； find outC．catches； findD．on； find

分析 如果房子著火了，弄清楚最近的出口．

解答 答案：B．be on fire 著火，為固定搭配，A in錯(cuò)誤，C catches前不能使用is，而where is the nearest exit是需要查清楚的內(nèi)容，應(yīng)使用find out．find側(cè)重找到，find out側(cè)重找出，弄清楚，查明白．

點(diǎn)評(píng) 本題考查介詞的辨析及find/find out的區(qū)別．平時(shí)應(yīng)多注重固定介詞短語(yǔ)的搭配及相近單詞或短語(yǔ)的區(qū)別．

1．Many people think it is safe to use a cell phone while they are driving．Yet Scores of studies suggest that real multitaskers-those who can carry out multiple （多個(gè)的） tasks equally well，make up just 2 percent of the population．More surprisingly，the so-called"supertaskers"actually have differently structured brains to the other 98 percent．
The brain areas that make supertaskers differ from the rest of the population are the same parts that are most different between humans and nonhuman primates （靈長(zhǎng)類），according to David Strayer，director of the applied cognition lab at the University of Utah．Scientists are unsure of the reason why some brains are different．In fact，we could all benefit from doing just one task at once．
In most of us，scientists have located a"bottleneck in the brain"that may explain why we find it hard to do two things at once．
The problem appears to be caused by a logjam of nerve messages．Faced with two almost simultaneous （同時(shí)的） tasks less than 300 milliseconds apart，the brain's ability to deal with the second one slows down．The neural （神經(jīng)的） response to the second task was postponed until the response to the first was completed．This means that with e-mails，phone calls，text messages and online social media all competing for our attention，often against a background of television，radio or music，our brains can reach information overload．
Scientists made the discovery after scanning the brains of volunteers attempting to multitask on a computer．The task was deliberately designed to involve the use of different senses and motorresponses．
Dr Rene Marois，one of the neuroscientists who carried out the experiment at Vanderbilt University in Nashville，Tennessee，said："Our research offers neurological evidence that the brain cannot effectively do two things at once．"The next step，the neuroscientists say，is finding out"why these areas cannot process two tasks at once．"

A．different supertaskers'

A．make a neural response               B．get ready for a response
C．complete a task                      D．finish two tasks

A．serf the Internet after listening to music
B．use a cell phone against a background of television
C．complete all kinds of tasks within the same day
