They built a slope（斜坡）so that a few of the penguins could save themselves.”和第三段中的“The case has taken the international media by storm”可知，從峽谷中救出企鵝這一事件引起了大家的熱議。 （2）考查推理判斷。m so glad.

Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates.

Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被動物用來通過逃離捕食者而活得更久，排除A；根據(jù)第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在這里我想指出的是，在某些物種中，尤其是那些表現(xiàn)出強烈兩性差異的物種，比如天堂鳥、孔雀，甚至在某些蝴蝶或魚類中，彩虹色的出現(xiàn)很可能是由性別選擇所驅(qū)動的。catching colors could be used as a cover173。t a new one.”引人注目的顏色可以用來偽裝，這種想法并不新鮮，排除C，故選D。根據(jù)最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我們的目標上驚人的彩虹表面在視覺上打破了原本可以辨認的目標形狀，這使得它們很難區(qū)分。 （3）考查推理判斷。實驗目的是看看鳥類的視角是否能提供幫助。 （4）考查主旨大意。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。 Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently. Another interesting characteristic of bat flight is the way in which bats landupside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force。Places where flying animals choose to land.B.Differences in the eating habits of bats and birds.D.They cannot hear any sound.B.They fly similarly to birds.D.the distance to the netsthe sense of flying heightC.the ability to change the speed（4）According to the passage, which of the following is NOT true? A.Bats can hang upside down like birds.C.D.以前人們認為蝙蝠和鳥類在運動方面沒有什么區(qū)別，但現(xiàn)在的研究證明蝙蝠的構(gòu)造不同于鳥類，它們的翅膀由前肢和后肢組成，它們自我調(diào)節(jié)能力好，可迅速改變飛行方向，或完全逆行，這是鳥類不容易做到的，而且蝙蝠飛行的另一個有趣特征是蝙蝠倒立著降落的！這不同于那些降落在地上或樹枝上的鳥。根據(jù)第一段中的Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.提出了蝙蝠與鳥的降落方式及飛行的不同。尤其是they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, somethi
