【正文】 根據第四。故選C。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到另一個點。我們可能很快就再也不用擔心數據安全問題了。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。D.How should you avoid information hackersC.s the best title of the passage? A.Its safety performance needs improving.D.Its core technology is controlled in foreign countries.B.It is a more apparent explanation of its safety.（3）What39。It tells of a kind of scientific appearance.C. words in the paper? A.Because it doesn39。t able to pass through sunlight.C.Because it is only data base located in space, which cannot be touched.B.s a testament(見證)to China39。 This Chinese experiment is a quite remarkable technological achievement, Artur Ekert, a professor of quantum physics at the University of Oxford, told BBC News. Despite these small issues, the scientific munity across the world has reacted positively to China39。 However, the technology does have a few limitations. For example, the process only works at night, as the information isn39。 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.re forever hearing about hackers leaking(泄露) s, passwords and other important personal information.8．閱讀理解 通讀全文可知，文章主要講述了海底噪音對海洋生物的影響以及如何降低海底噪音的問題，故選B。故選C。根據最后一段中的”And thanks to his work, we can better understand the effects of subsea sound pollution.“由于他的工作，我們可以更好地了解海底聲音污染的影響。故選A。s also possible to slow ships down to 18 km/h or less, which is less likely to seriously injure a whale.“也有可能將船只減速到每小時18公里或更少，這樣就不太可能嚴重傷害鯨魚。 （2）考查細節(jié)理解。故可知劃線部分單詞意思為“遲鈍的”。 （1）考查詞義猜測。D.Noise in the sea.C.Uncaring.（4）What is the text mainly about? A.Positive.Disapproving.Doubtful.To give the injured animals timely treatment.（3）What is the author39。To reduce the number of ships.C.s one way to solve the problem according to the text? A.D.C.B. The ocean is not our world, ments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.（1）What does the underlined word desensitised in Paragraph 2 mean? A. As for dealing with the root cause of the problem, the UN39。 What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It39。 It was not an easy task. Sound waves don39。 The whales had bee desensitised to the noise of approaching boats and were being struck by them, often seriously. We never thought that this could be something that could kill, recalls (回憶) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.7．閱讀理解 performance ”可知，機器人目前還在華盛頓州立大學的智能屋里進行測試，故選B?？v觀全文可知，本文介紹了一款由美國華盛頓州立大學的科學家們研發(fā)的機器人。根據最后一段中的“ While we are still in an early stage of development, our initial results with RAS have been promising”可知，Minor對這款機器人的未來發(fā)展充滿信心、非常樂觀，故選C。 performance…”可知，這臺機器人的表現還要經過進一步的測，說明正在測試階段，故選B。 （2）考查推理判斷。 （1）考查細節(jié)理解。D.RAS, the first robot to make home smart.B.Uncertain.（4）What can be a suitable title for the text? A.C.Negative.s attitude toward the future of RAS? A.It can cook for owners on its own.（3）What39。Its function remains to be tested.C.It is the first robot used in daily life.D.Through objects.C. performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.（1）How does RAS serve elderly people? A. RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently. The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.RAS bines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected, said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.6．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。根據最后一段中的“It39?？芍xB。根據第四段中的“Some are harmed visibly, stuck by abandoned things made of plastic.
