作为雅思考生，我们读外刊要有一定的目的性，不仅仅是为了扩大我们的阅读面，还要有意识地针对雅思考试，提高自己的水平。本文的话，我们做了一些注释，主要帮助大家习得雅思口语方面的知识。
For the experiment, the wheels were enclosed so that small animals could come and go but so that larger animals could not knock them over. Dr. Meijer set up motion sensors and automatic video cameras.Several years and 12,000 snippets of video later, she and Yuri Robbers, also a Leiden researcher, reported the results. They were released online Tuesday in the Proceedings ofthe Royal Society B.
为了进行试验，跑轮被围了起来，这样小动物就能来去自由，大动物则无法把它们撞翻。梅杰安放了运动传感器和自动摄影机。她和同为莱顿研究人员的尤里·罗伯斯(Yuri Robbers)报告称，几年后，他们获得了1.2万个视频片段。周二，这些结果被公布在了《英国皇家学报B》(Proceedingsof the Royal Society B.)的网站上。

Gene D. Block, chancellor of the University of California, Los Angeles, was not involved with the paper but knows Dr. Meijer and had seen the wheel set up in hergarden. He said the study made it clear that wheel-running is “some type of rewarding behavior” and“probably not driven bystress or anxiety.”
加州大学洛杉矶分校校长吉恩·D·布洛克(Gene D. Block)与这篇论文无关，但是他认识梅杰，而且还见过她在花园里放置的跑轮。他说，研究表明在跑轮上跑步是“一种有益的行为”，“可能不是出于压力或焦虑”。
【经典句式】
chancellor校长
setup安装;设置
rewarding有回报的
be driven by 出于
stress压力
anxiety焦虑
Mice accounted for 88 percent of thewheel-running events, and spent one minute to 18 on the wheel. The otheranimals each accounted for less than 1 percent. Frogs, though there were very few, were seen to get on the wheel, get off and get back on.
在所有在跑轮上跑步的动物中，小鼠占了88%，在跑轮上花费的时间为1到18分钟。其他每种动物所占的比例不到1%。虽然数量不多，但是我们也看到青蛙爬上跑轮，爬下来，然后又爬回去。
【小作文数据表达】
… account for xx percent of … ……占……的xx%
Russell Foster, a circadian rhythm researcher at Oxford University, said he read the paper and sent it out to other scientists on behalfof the Proceedings and was delighted when peer reviews from other scientists were positive.
罗素·福斯特(Russell Foster)是牛津大学(Oxford University)的一名生理节律研究员。他说他读过这篇论文，并代表《英国皇家学报B》把它发给了其他科学家。其他科学家都对此持肯定态度，这让他感到高兴。
【经典句式】
on behalf of代表
delighted高兴的
peer review同行评审
Marc Bekoff, a professor of ecology and evolutionary biology at the University of Colorado who is active in the animal welfare movement, said in an email thathe thought the paper did show that wheel-running could be a “voluntary activity,” but that mice in labs may be doing more of it because of the stress of confinement.
马克·贝科夫(Marc Bekoff)是科罗拉多大学(University of Colorado)的一名生态学和进化生物学教授，积极参与动物福利运动。他在电子邮件中说，他认为这篇论文的确表明跑轮运动可能是一种“自愿活动”，但是实验室的老鼠可能会因为禁闭的压力而进行更多跑轮运动。
【经典句式】
ecology生态学
evolutionary biology进化生物学
animal welfare movement动物福利运动
voluntary自愿的
stress压力
confinement限制
