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. mented lead author Kevin Healy from Trinity College Dublin. The study was done with a variety of animals using 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 the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly. In parison, the tiger beetle(虎甲蟲(chóng))runs faster than its eyes can keep up, basically being blind, which requires it to stop periodically to reevaluate its prey39。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.（1）What is the research mentioned in the passage mainly about？ A.Pace of life of animals.B.Impressive abilities of animals.C.Lifetime of small animals.D.Time perception of animals.（2）What does Kevin Healy39。s ment mean in ？ A.The survival of fast moving animals relies on their ability to perceive time.B.Animals with quicker pace of life have better perception of time.C.The ability of animals to perceive time depends on their high moving speed.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 process the information as quickly as they receive it.C.They can fly much faster than their eyes can keep up.D.They can send information to brain more quickly than to their eyes.（4）What will a tiger beetle have to do to catch a moving prey? A.Slow down to gain its time perception.B.Prevent itself from being blind.C.Stop occasionally to spot the prey again.D.Try to run as fast as it can.【答案】 （1）D（2）A（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了對(duì)動(dòng)物時(shí)間感知的研究。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“According to a team of researchers，an animal39。s ability to perceive（感知）time is linked to their pace of life.”可知，據(jù)一組研究人員稱，動(dòng)物感知時(shí)間的能力與它們的生活節(jié)奏有關(guān)，由此可知，文中提到的這個(gè)研究是關(guān)于動(dòng)物的時(shí)間感知的，故選D。 （2）考查推理判斷。根據(jù)第二段中的“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，對(duì)于能快速移動(dòng)的動(dòng)物而言，在極短的時(shí)間內(nèi)感知時(shí)間的能力可能是生與死的區(qū)別，由此可知，Kevin Healy說(shuō)的意思是快速移動(dòng)的動(dòng)物的生存依賴于它們對(duì)時(shí)間的感知能力，故選A。 （3）考查細(xì)節(jié)理解。根據(jù)第四段中的“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，家蠅觀察物體運(yùn)動(dòng)的時(shí)間比我們?nèi)搜鬯苓_(dá)到的時(shí)間要短，這使得它們能夠避免被擊中；再結(jié)合第五段中的“but they can make good decisions very quickly.”可知，它們可以很快做出好的決定，也就是說(shuō)它們可以盡快處理收到的信息，故選B。 （4）考查細(xì)節(jié)理解。根據(jù)倒數(shù)第二段中的“the tiger beetle（虎甲蟲(chóng)）runs faster than its eyes can keep up，basically being blind，which requires it to stop periodically to reevaluate its prey39。s（獵物）position”可知，虎甲蟲(chóng)的移動(dòng)比眼睛快，基本上是盲目的，這就要求它不時(shí)地停下來(lái)，重新評(píng)估獵物的位置，由此可知，為了抓住移動(dòng)的獵物，虎甲蟲(chóng)需要不時(shí)地停下來(lái)確定獵物的位置，故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。8．閱讀理解 When it es to modern munication, security is a big concern. It seems like we39。re forever hearing about hackers leaking(泄露) s, passwords and other important personal information. But thanks to a breakthrough by Chinese scientists, who won the 2018 Newb Cleveland Prize in February, we may soon never have to worry about our data again. This is thanks to the satellite called Micius that uses cuttingedge technology to send and receive information. Micius is the first satellite of its kind to use quantum key distribution(量子密匙分發(fā)), which uses particles (粒子) that transmit(傳輸) light to transfer information from one point to another. Currently, it can municate with two base stations(基站), both of which are located high up in the mountains in two different areas of Tibet, around 1,200 kilometers apart. Data is sent between the satellite and one of the base stations in the form of a ray of light. This makes it almost impossible for data sent and rec
