15．It's thrilling to imagine how future humans will have solved the problems we have now，or what amazing new inventions will make our lives more convenient and interesting．We asked top scientists to share their predictions on what the world will be like in a century．If they're right，the year 2114is going to be really cool．
*Robots will do your chores and more
Robots will be doing most of our jobs，from building homes to teaching math．There are already robots that clean floors and pump gas．In the future they will be more complicated and useful．Unfortunately，with robots taking all the jobs，unemployment will be high．
*You will read minds．
Speaking of being social，we will communicate in an entirely different way．Forget texts and emails．Mind-reading technology will allow us to send thoughts to each other without speaking a word．We will also be able to send thoughts to objects around us．（Instead of pressing"start"on the microwave，you could just think"start．"） Meanwhile，chips implanted（植入）in our brains will improve memory and intelligence．
*Your car will drive you
Today，around 30，000Americans die in car accidents each year．One hundred years form now，accidents will be a thing of the past．According to Mark Safford，consultant or the U．S．Department of Transportation，future cars will drive themselves．These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds．
*You will eat fake meat．
Raising animals is not an efficient way to produce food，and it harms the environment：Cows，chickens，and pigs eat a lot，and then we have to deal with all that poop（糞便）．What's more，that poop can end up poisoning lakes，rivers，and streams．Today，scientists can"grow"meat in a lab from animal cells，but it's expensive and not very delicious．In the future，they will have perfected the process．You'll order hamburgers that come from factories，not cows．Scientists may even find ways to make lab-grown meat tastier and healthier than the real thing．

分析 本文是一篇科教類閱讀，屬于說明文，主要介紹了2114年的未來前景，包括機器人為我們處理雜事、不用開口講話就可以表達想法、自動駕駛的轎車及食用人造肉．
解答 1．D．推理判斷題．由文章第二段Unfortunately，with robots taking all the jobs，unemployment will be high．可知，機器人普遍出現(xiàn)后，一些人會失去工作．故選D．
2．C．細(xì)節(jié)理解題．根據(jù)Forget texts and emails．Mind-reading technology will allow us to send thoughts to each other without speaking a word．可知，人們將來可以通過使用思維閱讀技術(shù)來默認(rèn)地傳達信息．故選C
3．推理判斷題．由文章第四段future cars will drive themselves．These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds．可以推斷出未來的轎車操作起來更加容易．故選B．
4．A．主旨大意題．本文的第一段是主題段，由該段中的share their predictions on what the world will be like in a century可知，本文主要描述了未來前景的預(yù)測．故選A
點評 本文是一篇科教類閱讀，題目涉及多道細(xì)節(jié)理解題，主旨大意題．做題時學(xué)生應(yīng)仔細(xì)閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測．
