【正文】 理解。根據第四段中的”Last month fast. ai, a nonprofit education organization based in San Francisco, kicked off the third year of its course in deep learning.“可知。上月，位于舊金山的非營利性教育機構 進入了它開辦深度學習課程的第三年。也就是說fast. ai是一個提供深度學習課程的組織，故選C。 （3）考查句義猜測。根據五段中的”To make it accessible to anyone who wants to learn …He says school mathematics is sufficient.“可知讓深度學習不再神秘是杰里米霍華德的目標，為此，他和數(shù)學家雷切爾，讓任何想學習編寫AI軟件的人都能學習這門技術?；羧A德說有中學數(shù)學知識就足夠了。，僅需要中學數(shù)學知識。因此霍華德說No. Greek. Letters”沒有，希臘，字母“是想說fast, ai的深度學習課程很簡單。故選A。 （4）考查推理判斷。根據最后一段中的”If Mr Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind. “如果霍華德和其他人如愿以償，那么讓AI軟件開發(fā)變得更容易將會催生出一批新的不同的果實。由此推斷簡化軟件開發(fā)可能會導致意料之外的結果。故選D。 【點評】本題考點涉及細節(jié)理解，句義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，要求考生準確掌握細節(jié)信息，同時根據上下文的邏輯關系，進行分析，推理，從而選出正確答案。7．閱讀理解 When it es to modern munication, security is a big concern. It seems like we39。re forever hearing about hackers leaking(泄露) s, passwords and other important personal information. 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. Micius is the first satellite of its kind to use quantum key distribution(量子密匙分發(fā)), which uses particles (粒子) that transmit(傳輸) light to transfer information from one point to another. Currently, it can municate with two base stations(基站), both of which are located high up in the mountains in two different areas of Tibet, around 1,200 kilometers apart. Data is sent between the satellite and one of the base stations in the form of a ray of light. This makes it almost impossible for data sent and received using quantum satellite technology to be stolen, as the connection will be broken if someone tries to hack it. Any eavesdropper(偷聽者) on the quantum channel attempting to gain information … can be found by the municating users, the scientists wrote in the paper. However, the technology does have a few limitations. For example, the process only works at night, as the information isn39。t able to pass through sunlight. Despite these small issues, the scientific munity across the world has reacted positively to China39。s achievements in this groundbreaking project. This Chinese experiment is a quite remarkable technological achievement, Artur Ekert, a professor of quantum physics at the University of Oxford, told BBC News. And Karl Ziemelis, an editor for Nature, told Xinhua, It39。s a testament(見證)to China39。s investments and significant efforts in the physical sciences that this group has been able to push research in practical quantum munication technologies to such an astronomical(天文學的)height.（1）According to the passage, why Micius is safe for transporting messages? A.Because it is only data base located in space, which cannot be touched.B.Because it only works at night, as the information isn39。t able to pass through sunlight.C.Because it uses particles that transmit light to transfer information from one to another.D.Because it doesn39。t score any important private information like passwords and s.（2）Which of the following can best describe scientists39。 words in the paper? A.It gave out the working principle of Micius.B.It tells of a kind of scientific appearance.C.It warned hackers not to steal information from Micius.D.It is a more apparent explanation of its safety.（3）What39。s the main problem of Micius? A.Its core technology is controlled in foreign countries.B.Light is a must in its working process.C.Its safety performance needs improving.D.Sunlight has a deadly influence on its working.（4）What39。s the best title of the passage? A.Leaping into an age of secure dataB.How should you avoid information hackersC.Old Problem, New ApproachesD.Taking on data theft【答案】 （1）C（2）B（3）D（4）A 【解析】【分析】本文主要講述了對于現(xiàn)代通信，安全是一個大問題。似乎我們總是聽到黑客泄露電子郵件、密碼和其他重要的個人信息。最近中國發(fā)射了一顆名為墨子號的衛(wèi)星，它使用尖端技術來發(fā)送和接收信息。我們可能很快就再也不用擔心數(shù)據安全問題了。 （1）推理判斷題。根據第三段第一句Micius is the first satellite of its kind to use quantum key distribution(量子密匙分發(fā)), which uses particles (粒子) that transmit(傳輸) light to transfer information from one point to another.（墨子號是第一顆使用量子密鑰分配（quantum key distribution，量子密鑰分配）的衛(wèi)星，它使用傳輸光的粒子將信息從一個點傳輸?shù)搅硪粋€點。）可知，因為使用量子來傳輸，所以不會泄露重要的個人信息。故選C。 （2）推理判斷題。根據第四段Any eavesdropper on the quantum channel attempting to gain information … can be found by the municating users, the scientists wrote in the paper.（科學家們在論文中寫道：任何試圖獲取信息的量子信道竊聽者……都可以被正在通信的用戶發(fā)現(xiàn)。）可知，科學家在論文中的表述講述了一種科學現(xiàn)象。故選B。 （3）推理判斷題。根據第五段中For example, the process only works at night, as the information isn39。t able to pass through sunlight.（例如，這個過程只在晚上進行，因為信息無法通過陽光。）可知，墨子號衛(wèi)星的主要問題是陽光對它的工作有致命的影響。故選D。 （4）主旨大意題。根據文章主要內容為介紹中國墨子號的衛(wèi)星，它使用尖端技術來發(fā)送和接收信息，從而保護人們的信息安全。預示著我們將會進入數(shù)據安全時代。故選A。 【點評】考查閱讀理解。本文涉及推理判斷題和主旨大意題兩種常考題型。推理判斷題根據結合上下文進行合理的推斷，不主觀臆斷。主旨大意題把握文章的首尾段和關鍵詞。8．閱讀短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 The world39。s insects are going down the path of extinction, threatening a catastrophic collapse of nature39。s ecosystems, according to the first global scientific review. More than 40％of insect species are declining and third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. It should be of huge concern to all of us, for insects are at the heart of every food web. They pollinate (授粉) the large majority of plant species, keep the soil healthy, recycle nutrients, control pests, and much more. Love them or 1oathe them, we humans cannot survive without insects, said Prof Dave Goulson at the University of Sussex in the UK. The analysis, published in the journal Biological Conservation, says intensive (集約型) agriculture is the main driver of the declines, particularly the heavy use of pesticides. Urbanisation and climate change are also significant factors. If insect species losses cannot be stopped, this will have catastrophic consequences for both the planet39。s ecosystems and for the survival of mankind. It is very rapid. In 10 years you will have a quart
