一、阅读理解。
According to a team of researchers,an animal's 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 the 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 shows 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 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(虎甲虫)runs faster than its eyes can keep up,basically becoming blind,which requires it to stop periodically to reevaluate its prey's(猎物)position.
Our results suggest that time perception offers an as yet unstudied dimension in which animals can specialize and there is a considerable range to study this system in more detail.
1.What is the research mentioned in the passage mainly about?
A.Pace of life of animals.
B.Time perception of animals.
C.Lifetime of small animals.
D.Impressive abilities of animals.
2.What does Kevin Healy's comment mean in Para.2?
A.The ability of animals to perceive time depends on their high moving speed.
7
B.The survival of fast moving animals relies on their ability to perceive time.
C.Animals with quicker pace of life have better perception of time.
D.Animals with poor ability of time perception have a shorter life.
3.Why can houseflies avoid being hit?
A.They can think very deeply before they act.
B.They can fly much faster than their eyes can keep up.
C.They can process information as quickly as they receive it.
D.They can send information to the brain more quickly than to their eyes.
【解题导语】本文是一篇科普说明文。研究发现,动物感知时间的能力和它们的生活节奏有关,对于快速移动的动物来说,在短时间内感知时间的能力决定着它们的生死。文章列举了家蝇、狗和虎甲虫等动物,证明了动物感知时间的能力的重要性。
1.B 考查主旨大意。通读全文可知,“According to a team of researchers, an animal's ability to perceive(感知)time is linked to their pace of life”为本文的主题句;结合下文内容可知,本文主要介绍了一项研究发现:动物感知时间的能力和它们的生活节奏有关,故B项正确。
2.B 考查细节理解。根据第二段Kevin Healy所说的话“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”可知,Kevin Healy认为,对于快速移动的动物来说在短时间内感知时间的能力决定着它们的生死;据此可知,该句是说快速移动的动物的生存依赖于它们对时间的感知能力,故B项正确。
3.C 考查细节理解。根据第四段的“The research shows flies observe motion in a shorter time than our own eyes can achieve,which allows them to avoid being hit”可知,家蝇能比我们在更短的时间内感知到物体的运动,这是它们得以避免被拍死的原因,故C项正确。
二、单句语法填空
1.It is vital that these forms ________ (send) back as early as possible.
答案:(should) be sent It is vital that ... “……是十分重要的”。其中that从句谓语动词应用“should+动词原形”,should可以省略。

答案:With with the aid/help of ... “在……的帮助下”。
3.You'd better put things back ________ place. Otherwise, it will be difficult

to find them.
答案:in in place “在适当的位置”。
4.We ________ (watch) TV when there was a power failure.
答案:were watching be doing ... when ... “正在做……这时……”,再由“there was ...”可知应用过去进行时,故填were watching。
5.The new technology, if ________ (apply) to rice growing, will help increase the grain output.
答案:applied 从句为状语从句的省略形式。The new technology与apply之间为逻辑上的被动关系,故应填过去分词作状语。
6.Men and women should ________ (treat) equally in education and employment.
答案:be treated treat和Men and women在逻辑上存在动宾关系,应用被动语态。
7.His head had struck the wall and ________ (bleed).
答案:was bleeding 此处表示头部正在流血,前一分句用了过去完成时,故此处应用过去进行时,表示过去某时正在持续的状态。
8.Everyone arrived late at the party for ________ (variety) reasons.
答案:various 修饰名词reasons应用形容词,表示“各种各样的”,故填various。
9.Television violence ________ (poison) the minds of young people.
