【正文】 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. When it es to modern munication, security is a big concern. It seems like we39。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。根據(jù)第四段中的“But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. ”但是熱量會隨著時間的推移而消失，不管周圍的物質(zhì)有多好，所以研究小組建立了一個化學儲存系統(tǒng)，可以將能量保持在一個穩(wěn)定的分子結(jié)構(gòu)中)可推斷，這種分子結(jié)構(gòu)的優(yōu)勢是相對穩(wěn)定。故選A。 （3）考查細節(jié)理解。根據(jù)第二段中的“thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing. ”多虧了這種能在白天吸熱之后以熱能形式釋放的新型材料，這個透明的聚合物膜可以應用于許多不同的表面，如窗戶玻璃或服裝)可知，這種聚合物膜可以吸熱，此后再以熱能的形式釋放出來。故選C。s energy and then releases it as heat to make the ice on the windshield disappear. ”想象一下你的衣服可以釋放足夠的熱量讓你溫暖和舒適，讓你可以在冰冷的房間里保持舒適。 （1）考查推理判斷。Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solidstate films. The new approach is the first based on a solidstate material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.（1）What is the main purpose of Paragraph 1? show the main idea of the passage. practice readers39。 s energy through a chemical reaction and releasing it later as heat. According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay fortable in a cooler room. Or, picture a car windshield that stores the sun39。 【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)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。 （4）考查主旨大意。實驗目的是看看鳥類的視角是否能提供幫助。 （3）考查推理判斷。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。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。catching colors could be used as a cover173。根據(jù)第一段中的“A good disguise keeps you hidden, right? 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。Shining colors as a sexual strategy【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】本文是一篇說明文，介紹了彩虹色有助于生物隱藏。Metallic iridescent as the best disguiseC.A famous camouflage strategyWhy birds are not effected by iridescent insects.D.Whether there are any differences between bees and birds.B.If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding itD.Bees can always tell the difference between a circle and an ovalB.D.catch the attention of their matesC.live a little longer by escaping their predator(捕食者)s173。s concealment？ s concealment39。Coloration in the Animal Kingdom, already in 1909, that 39。up isn39。 The idea that eye173。 And in our research group we are of course interested in why this vivid metallic color is so widespread in nature. 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. Shining iridescent color, which changes depending on the angle from which it39。6．犇犇閱讀理解 是一篇環(huán)境保護類閱讀，因此選C。 （4）考查推理判斷。根據(jù)最后一段中的“It39?？芍xB。根據(jù)第四段中的“Some are harmed visibly, stuck by abandoned things made of plastic.
