【正文】 antage of the device? A.s a growing need for that now. In large public areas, it39。2．犇犇閱讀理解根據(jù)第三段中的“The calving of A68 provides us with a unique opportunity to study marine life...”可知A68冰山的形成為科學家提供了研究海洋生物的獨一無二的機會，所以Professor David Vaughan認為科學家要果敢地抓住這次機會，故this one指的是A68冰山和它下面的生態(tài)系統(tǒng)。The ice sheets in Greenland and Antarctica are melting at a steady rate.C.Climate change in Antarctica.C. Professor David Vaughan, science director at the BAs, said, We need to be bold (大膽的) on this one. Larsen C is a long way south and there39。To explore a new way to prevent climate change.D.It will disappear in a very short time.D.根據(jù)第二段中的“Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light.”可知，科學家著急趕去世界最大的冰山是為了在其受到光照影響之前研究這座冰山下面的海洋生態(tài)系統(tǒng)。根據(jù)最后一段中的“…At the current rate, the world39。 The peerreviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online. Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes, researchers said.（1）What does paragraph 3 talk about? A.B.It protects personal information from being disturbed.（3）Why did the researchers study the device according to Yingying Chen? A.To make full use of WiFi.C.B.根據(jù)第四段中的“noting its design can inspect bags or luggage without being an exposure to privacy.”可知，不用打開和檢查人們的個人物品，避免了侵犯隱私，可知選D。 【點評】本題考點涉及細節(jié)理解，詞義猜測，推理判斷和段落大意四個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)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。on effect on other areas of policy making.

A.t effected much.【答案】 （1）C（2）B（3）A 【解析】【分析】本文是一篇說明文，介紹了營養(yǎng)指南對地球也有利。 （2）考查詞義猜測。根據(jù)第三段中的“A third of the ice173。 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. Coloration in the Animal Kingdom, already in 1909, that 39。s173。catch the attention of their matesC.Whether there are any differences between bees and birds.B.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。 （3）考查推理判斷。t need to waste energy making immune cells to fight off tomorrow39。organs will speed up metabolic processes to answer itC. study? A. （1）考查推理判斷。 （3）考查推理判斷。 【點評】本題考點涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要根據(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。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.故選C。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。t tell what your blood type is from a faraway place.

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(yīng)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。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。 re happy, but to slow down dramatically when we39。因此，當我們的身體需要額外的能量時，（我們的身體）會去找免疫系統(tǒng)。Our ancestors evolved their immune systems in fighting against fierce animals.C.B.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______.
