AI is still no match for human qualities.可知，人工智能仍無法與人類素質(zhì)相匹敵，由此可知，在不久的將來，人工智能新聞主播不會取代人類新聞主播，故選C。 The idea that eye173。A famous camouflage strategyt 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。D.D.根據(jù)第四段中的“The fact that the particles landed in the ocean, instead of on land, means larger pieces may have survived and can be studied.”可知，科學(xué)家更喜歡在海洋中尋找流星是因為他們可能會發(fā)現(xiàn)更大的巖石顆粒。d never have seen these responses if the park hadn39。To introduce how wolves behave in the wild.B.根據(jù)第五段中的“To learn more about just how wolves are beneficial, a short documentary from Quest explains how the presence of wolves influences the behavior of deer, which eventually makes entire ecosystems more biologically diverse and healthy.”可知，拍攝紀錄片的目的是了解狼是如何對生態(tài)有益的。But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life. 人們要用智慧來決定做什么才是最好的。 （1）考查詞義猜測。 Yellowstone National Park is a typical example of just how wolves can help repair an ecosystem. An October 2018 study analyzed 40 years of research on large animals inside the park. （2）考查推理判斷。To examine creatures of the explored ocean.（2）What mainly caused the start of the search in the sea? A.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。Whether there are any differences between bees and birds.B.s173。 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. （3）考查推理判斷。This technology is very perfect so farB. Both the technologies used to make Xin39。 News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world39。故選D。 （3）考查細節(jié)理解。The condition of animal species in Antarctica.（3）What can we learn about the A68 iceberg from the text? A. The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change, she said. It is important that we get there quickly before the undersea environment changes as sunlight enters the water. A team of international scientists is due to set off for the world39。To study how the iceberg was formed.B.冰山下面顯現(xiàn)的新的海洋生態(tài)系統(tǒng)為科學(xué)家提供了研究未知的海洋生物的機會。s measurement bodies achieve at the meeting held in Versailles? will e up with seven new SI units. will set May 20th as a new international festival. will redefine four SI units including the kilogram. will decide on a new measure used in the laboratory.【答案】 （1）B（2）D（3）A（4）C 【解析】【分析】本文是一篇說明文，法國凡爾賽宮舉辦的國際計量大會，將對目前使用的國際單位制中的四個基本單位進行重新定義，其中包括對千克的重新定義。根據(jù)最后一段中的“At a meeting in Versailles, France, on November 16th, 2018, the world39。 To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro electric motors behind her face move to make her expressions seem more human. （1）考查詞義猜測。 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. Those surprising results appear in the journal Scientific Reports.brilliantly changeable or metallic colors are among the strongest factors in an animal39。conceal themselves when in danger根據(jù)最后一段說研究人員目前正在對鳥類進行實驗，這些鳥類的飲食中經(jīng)常含有彩虹色的昆蟲。To observe movements of the universe.C.They like to explore strange sea areas.Describe the process of the search.【答案】 （1）C（2）A（3）B（4）B 【解析】【分析】本文是一篇說明文，科學(xué)家們發(fā)現(xiàn)了他們認為是去年墜落地球的流星碎片。 【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(zhǔn)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。It helps prove the importance of protecting wolves.C.故選B。 how real people behave and react, as against how one would like them to behave and react. One can read and hear lot of idealistic stuff about how to make the world a better place, which would be found if it was based on an accurate observation of human nature, but which is basically a waste of time because it is not.（1）According to the writer, the great discoveries made by Albert Ei
