9．If you saw another kid ride her bike too fast around a corner and fall down，you might ride your bike more slowly on that turn．Yes，we humans are very sensitive to others'mistakes．And the same is true for other animals．Animals mess up all the time．They might eat poisonous leaves，fall off a tree or let their prey（獵物） slip away．By watching others fail，an animal can avoid making the same mistakes，thus improving its chance of survival．
Scientists suspected that one part of the brain helps animals process information about others'errors．Cells in that part appear to become more active when a person sees someone else making a mistake．But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors．
To investigate the brain's response to errors in more detail，the researchers taught a game to two macaques，a type of monkey．One monkey could press a yellow or green button while the other watched．If the first monkey pressed the right button，the team gave both animals a treat．Every couple of rounds，the two monkeys switched roles．Meanwhile，the scientists monitored individual cells in the animal's brains．
When the first monkey messed up the game by pressing the wrong button，a group of cells in the second monkey's brain fired．But if the second monkey also made the wrong choice during its turn，some of the cells in that group didn't respond．Those unresponsive cells reacted specifically to mistakes made by others，not to the monkey's own mistakes．
Scientists believe other parts of the brain also might help people process information about another's errors．"You start to think about this other person and see things from his angle．"Ellen de Bruijn told Science News．She studies the brain at the University of Leiden in the Netherlands．

分析 本文告訴人們我們?nèi)祟悓?duì)其他人的錯(cuò)誤是非常敏感的，動(dòng)物也是一樣的．科學(xué)家懷疑大腦的一部分幫助動(dòng)物處理關(guān)于其他動(dòng)物錯(cuò)誤的信息
解答 31．B．細(xì)節(jié)理解題．根據(jù)第一段最后一句By watching others fail，an animal can avoid making the same mistakes，thus improving its chance of survival．通過(guò)觀察其他人的失敗，動(dòng)物能避開(kāi)犯同樣的錯(cuò)誤，因此提高了它生存的可能，故選B．
32．D．詞義猜測(cè)題．根據(jù)第二段第一句Scientists suspected that one part of the brain helps animals process information about others'errors．科學(xué)家懷疑大腦的一部分幫助動(dòng)物處理關(guān)于其他動(dòng)物錯(cuò)誤的信息．第二段最后一句But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors．研究者不知道是否在大腦的這一部分在檢測(cè)單個(gè)細(xì)胞中扮演不同的角色，故選D．
33．C．細(xì)節(jié)理解題．根據(jù)第二段提到To investigate the brain's response to errors in more detail，the researchers taught a game to two macaques，為了檢查大腦對(duì)于錯(cuò)誤的反應(yīng)，研究者對(duì)了兩組實(shí)驗(yàn)，故選C．
34．A．細(xì)節(jié)理解題．根據(jù)倒數(shù)第二段最后一句Those unresponsive cells reacted specifically to mistakes madeby others，not to the monkey's own mistakes．那些反應(yīng)遲鈍的細(xì)胞由別人的錯(cuò)誤發(fā)生特異性反應(yīng)，不是對(duì)猴子自己的錯(cuò)誤．故選A．
35．A．主旨標(biāo)題．本文告訴人們我們?nèi)祟悓?duì)其他人的錯(cuò)誤是非常敏感的，動(dòng)物也是一樣的．科學(xué)家懷疑大腦的一部分幫助動(dòng)物處理關(guān)于其他動(dòng)物錯(cuò)誤的信息，故選A．
點(diǎn)評(píng) 本篇文章主要是細(xì)節(jié)理解方面的題型，需要考生通過(guò)跳讀迅速找到對(duì)應(yīng)的句子進(jìn)行詳細(xì)理解，句子的理解可以結(jié)合上下文意思，通過(guò)邏輯推理得到．
