【正文】 作為學(xué)生的你,在遇到麻煩的時(shí)候,是怎么想的呢?請(qǐng)說(shuō)說(shuō)你的看法,60個(gè)詞左右。根據(jù)倒數(shù)第二段中的“the tiger beetle runs faster than its eyes can keep up,basically being blind,which requires it to stop periodically to reevaluate its prey’s position”可知,虎甲蟲(chóng)的移動(dòng)比眼睛快,基本上是瞎的,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)重新確定獵物的位置。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. 【解析】選C。細(xì)節(jié)理解題。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(lài)于它們對(duì)時(shí)間的感知能力。2. What does Kevin Healy’s ment mean in Para. 2?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. 【解析】選A。細(xì)節(jié)理解題。閱讀理解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,” 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 i
