Question

2．We usually believe what our brain tells us，but there is some amazing evidence which shows that the brain tricks us．As a result，we can ignore things that actually are there．Psychologists Daniel Simons and Christopher Chabris have researched this phenomenon，which they call'change blindness'．
The′Invisible Gorilla（看不見的大猩猩）experiment is probably their most famous one，and it is described in many psychology textbooks．In this experiment，the participants were shown a video of two groups of people （one group in white T-shirts and the other group in black T shirts）who passed basketballs around in a hall．Simons and Chabris asked people to count how many times the white team passed the ball．While the two teams were passing their balls around，a person who was dressed up as a gorilla walked through the group and stopped to look at the camera．Simons and Chabris found that about half of the research participants did not notice the gorilla．
Simons and Daniel Levin did another experiment，called the'Door Study'．Participants in this study were walking across a university campus（校園）when they were stopped by someone they didn't know．The stranger asked for directions and the participant started to give the directions．While the participant was talking to the stranger，two men who were carrying a wooden door talked between the participant and the stranger．At this point，the stranger swapped places with one of the men carrying the door．After that，the participant continued to give the directions．Once again，about half of those tested did not notice that，when the door as passing by，the stranger had changed places with a man who as taller，thinner and who sounded different．
It just goes to show how we can't always trust our own rains．Even though we may think we know what is going on，we can be blind to large changes in our environment．

Answer 1

分析 本文講述了一種特殊的大腦感知現(xiàn)象：變化盲視現(xiàn)象：人們看到不存在的事物或是忽視存在的事物的大腦"欺騙"人的現(xiàn)象．并講述了著名的變化盲視實驗．

解答 28．D．細(xì)節(jié)理解題．根據(jù)Simons and Chabris asked people to count how many times the white team passed the ball可知，這個實驗要求人們關(guān)注白隊傳球的次數(shù)．故選D．
29．C．推理判斷題．根據(jù)The stranger asked for directions and the participant started to give the directions．While the participant was talking to the stranger，two men who were carrying a wooden door talked between the participant and the stranger．At this point，the stranger swapped places with one of the men carrying the door．After that，the participant continued to give the directions．Once again，about half of those tested did not notice that，when the door as passing by，the stranger had changed places with a man who as taller，thinner and who sounded different．可以推測出，他們想要研究人們是否會注意觀察在和不同的人交流時．故選C．
30．A．推理判斷題．根據(jù)While the two teams were passing their balls around，a person who was dressed up as a gorilla walked through the group and stopped to look at the camera．Simons and Chabris found that about half of the research participants did not notice the gorilla．以及文章內(nèi)容可以推斷出，人們忽視眼前的事是因為專注于一些事．故選A．
31．C．推理判斷題．根據(jù)文章內(nèi)容可知，本文主要講述了一種特殊的大腦感知現(xiàn)象，屬于科普文，應(yīng)該來自于科學(xué)雜志．故選C．

點評 考查學(xué)生的細(xì)節(jié)理解和推理判斷能力．做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確選擇．在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
