5.According to a team of researchers,an animals'ability to perceive(感知)time is linked to their pace of life.
"Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures."commented lead author Kevin Healy from Trinity College Dublin.
The study was done with a variety of animals using a phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant.Dogs,for example,have eyes with a refresh rate higher than humans.
One example of this phenomenon at work,the authors say,is the housefly and its ability to avoid being hit.The research showed flies"observe motion in a shorter time than our own eyes can achieve,"which allows them to avoid being hit.
Professor Graeme Ruxton of the University of St Andrews in Scotland,who worked jointly on the research project,said in a statement,"Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly.Thus,this work highlights(強調(diào)) the impressive abilities of even the smallest animal brains.Flies might not be deep thinkers,but they can make good decisions very quickly."
In comparison,the tiger beetle (虎甲蟲)runs faster than its eyes can keep up,basically becoming blind,which requires it to stop periodically to re-evaluate its prey's (獵物)position.
Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.

分析 本文講述了關(guān)于動物對時間的感知和生活的節(jié)奏的研究,例如蒼蠅很少會被人類拍到、虎甲蟲時常停下觀察獵物等.
解答 32.B.細(xì)節(jié)理解題.由第一段According to a team of researchers,an animals'ability to perceive(感知)time is linked to their pace of life,可知研究主要是關(guān)于動物對時間的感知和生活的節(jié)奏,故選B.
33.B.細(xì)節(jié)理解題.由第二段Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures,我們的研究結(jié)果支持了動物對時間感知的重要性,在短時間內(nèi)感知時間的能力可能是快速移動的生物生存與死亡的區(qū)別,故選B.
34.C.細(xì)節(jié)理解題.由第四段The research showed flies"observe motion in a shorter time than our own eyes can achieve,"which allows them to avoid being hit,可知蒼蠅不會被人擊中的原因是它們觀察、運動比人眼所用的時間要短得多,故選C.
35.D.細(xì)節(jié)理解題.由倒數(shù)第二段the tiger beetle (虎甲蟲)runs faster than its eyes can keep up,basically becoming blind,which requires it to stop periodically to re-evaluate its prey's (獵物)position,虎甲蟲運行速度比它的眼睛快,導(dǎo)致它基本上成為盲人,這要求它不時地停止,重新評估它的獵物的位置,故選D.
點評 本篇文章都是細(xì)節(jié)推理題,答題的已給選項也一般不會和短文相關(guān)詞語完全相同,需要考生自己理解句子,延伸推理出題目答案,比一般細(xì)節(jié)理解題偏難.
