Question

5．Have you ever felt somebody else's pain？You're not alone，with new research showing some people do have a physical reaction to others'injuries．
British researchers used brain-imaging technology （影像工程學(xué)） to show that people who say they feel the pain of others have heightened activity in pain-sensing brain regions（區(qū)域） when they see someone else being hurt．For the study，the researchers exposed 108college students to images（圖象） of painful situations，ranging from athletes suffering sports injuries to patients receiving an injection．Nearly a third said that，for at least one image，they not only had an emotional reaction，but also felt pain in the same site as the injury in the image．
The researchers found that while viewing the painful images，both people who said they felt pain and those who did not showed activity in the emotional centers of the brain．But those who felt pain showed greater activity in pain-related brain regions compared with the others．
"Patients with functional pain experience pain in the absence of an obvious disease or injury to explain their pain．This confirms that at least some people have an actual physical reaction when observing others being injured or expressing pain，"Dr．Stuart Derbyshire of the University of Birmingham，one of the researchers，told reporters．
He noted that the people reported feeling pain also tended to say that they avoided horror movies and disturbing images on the news-so as to avoid being in pain．
The findings were published in the December issue of the journal Pain．

Answer 1

分析 一項(xiàng)研究發(fā)現(xiàn)有的人可以對別人的痛苦感同身受，科學(xué)家對這些人的大腦影像做了詳細(xì)研究．

解答 9．B．猜測詞義題．根據(jù)第二段的句子For the study，the researchers exposed 108 college students to images of painful situation，ranging from athletes suffering sports injuries to patients receiving an injection．可知后面的a third指的是參與研究的36個學(xué)生．故選B．
10．A．細(xì)節(jié)理解題．根據(jù)第三段的句子The researchers found that while viewing the painful images，both people who said they felt pain and those who did not showed activity in the emotional centers of the brain．可知研究人員觀察學(xué)生大腦區(qū)域的情感活動．故選A．
11．B．細(xì)節(jié)理解題．根據(jù)倒數(shù)第二段的句子He noted that the people reported feeling pain also tended to say that they avoided horror movies and disturbing images on the news-so as to avoid being in pain．可知如果對痛苦敏感，最好不要看恐怖電影．故選B．
12．C．主旨大意題．根據(jù)第一段的句子Have you ever felt somebody else's pain？You're not alone，with new research showing some people do have a physical reaction to others'injuries．可知這篇文章介紹的是有的人能感覺到別人的痛苦．故選C．

點(diǎn)評 在對科技說明文進(jìn)行閱讀理解是，考生可以尤其注意中心句，中心段（首尾）、轉(zhuǎn)折句和問題中出現(xiàn)的詞，尤其是一些很有特點(diǎn)的詞如專有名詞．在文段中快速找到相應(yīng)詞語所在位置，問題的答案往往就在附近．
