I can only 　2　 myself—it’s like losing a family member. My daughter didn’t sleep for three days. She just thought her pet was 　3　.  My family had almost lost 　4　 until Erica decided to offer her services. She uses a drone (无人机) to help find lost dogs. Equipped with a hi-tech thermal imaging (热成像) camera, the drone can detect heat 　5　 from 250 feet in the air. 　6　, when asked to help out in a search for a 　7　, Erica simply turns up to the dog’s last known 　8　 and sets up the drone. Having found more than 160 dogs, it’s proved pretty 　9　.  And it’s easy to see why. Can you 　10　 Chester running around these woods? To the naked eye (肉眼), it’s virtually impossible, but pop the thermal image up and he jumps out, 　11　 his owner to bring him safely back home.  Having saved hundreds of dogs, the method is clearly 　12　. Erica doesn’t 　13　 for her services and instead does it for the pleasure of seeing the owners 　14　 with their dogs.  Erica’s drone has helped create countless happy 　15　 and is sure to make many more in the future.  (　)1.A.concerned 　　　B.annoyed C.scared D.confused (　)2.A.speak for B.focus on C.turn to D.adapt to (　)3.A.sick B.gone C.injured D.stuck (　)4.A.attitude B.contact C.track D.hope (　)5.A.impressions B.signals C.experiments D.behaviours (　)6.A.Besides B.However C.Therefore D.Otherwise (　)7.A.family B.job C.chance D.dog (　)8.A.location B.company C.adventure D.arrangement (　)9.A.particular B.familiar C.successful D.suitable (　)10.A.spot B.explore C.concentrate D.rescue (　)11.A.forbidding B.allowing C.ordering D.warning (　)12.A.challenging B.improving C.working D.surviving (　)13.A.apply B.wish C.answer D.charge (　)14.A.reunited B.recognised C.requested D.admired (　)15.A.destinations B.solutions C.goals D.endings ●Ⅵ 阅读七选五(每小题2.5分,满分12.5分) Scientists make amazing paint using ideas from nature The colour in most paint comes from pigments (颜料)—coloured things such as minerals, metals or chemicals. But nature has another way to create colour, called “structural colour”. Structural colour comes from tiny shapes on the surfaces of things like wings, feathers or shells. 1.　　　　 Now scientists have used nanotechnology (纳米技术) to make paint with structural colour.  2.　　　　 They were trying to create a special mirrored surface. But they found super-small clumps of aluminum atoms (铝原子团块) on the surface. The researchers were upset because these small clumps messed up the mirror. Then they realised that the clumps made colour when light hit them. They decided to turn their discovery into paint.  All the colour in the new paint comes from aluminum. There are tiny aluminum pieces and then even smaller nanoparticles (纳米颗粒) that create the colour. The nanoparticles don’t really produce the colour. They simply reflect back single colour. 3.　　　  Because the new paint doesn’t have pigments, the paint is so light that it could reduce the amount of fuel used by planes and cars. 4.　　　　 It would only take 1.3kg of structural paint to do the same job.  5.　　　　 In regular paint, pigments break down and fade over time. That’s not true for structural colour. Once we paint something with structural colour, it should stay for centuries. What’s more, the new paint doesn’t heat up like regular paint. That’s true even for darker colour. The new paint can keep surfaces up to 16.6℃ cooler than normal paint. Using the paint on buildings in cities could help cool cities and reduce the electricity spent on air conditioning.  A.The new paint has several other advantages. B.Structural paint could save as much money as possible. C.Researchers weren’t really planning on making paint.　 D.The size of them determines which colour gets reflected. E.Generally, it takes about 500kg of paint to cover an airplane. F.Normally, we never see the shapes because they’re so small. G.It will probably be a while before you can use structural colour. ●Ⅶ 语法填空(每小题1.5分,满分15分) China’s state-run news agency Xinhua introduced two newest members of its newsroom at the 1.　　　　　　(five) World Internet Conference in Wuzhen. The groundbreaking AI news anchors (节目主持人), one speaking Chinese and 2.　　　　 other English, are the world’s first news anchors based 3.　　　　 the latest AI technology.  Chinese viewers are greeted with a digital version of a regular Xinhua news anchor 4.　　　　(name) Qin Hao. The anchor, 5.　　　　　　(wear) a red tie and blue suit, nods his head in emphasis, raising his eyebrows (眉毛) slightly. “Not only can I accompany (陪伴) you 24 hours a day, 365 days a year, 6.　　　　　 I can be endlessly copied and present at different scenes,” he said.  The English-speaking AI anchor adds, “The development of the media industry calls for 7.　　　　　　　　　(continue) creation and deep 8.　　　　　　　　　(combine) with the international advanced technologies. I look forward to bringing you brand new (崭新的) news experiences.”  The AI anchors 9.　　　　　　　　(join) the daily news reporting team already, reporting news on the agency’s social media platforms (平台). There is no doubt 10.　　　　 they have immeasurable prospects for the future news reporting as they can reduce production costs and improve accuracy and efficiency.  学科网（北京）股份有限公司 $ Period Four　Lesson 3 Internet and Friendships (Reading) Ⅰ.1.hug　2.shallow　3.maintain　4.opinions 5.authority　6.percent Ⅱ.1.concentration　2.briefly　3.creative　4.harmful 5.argument　6.rewarding　7.limiting　8.additional 9.replacement　10.basically Ⅲ.1.In addition　2.focus/concentrate on　3.was concerned with　4.stays/keeps in touch with　5.on the basis of Ⅳ.1.think it necessary to hold such an activity regularly　2.It was your help that　3.No matter what challenges you face 4.hidden behind her shyness Ⅴ.【文章大意】 本文是一篇记叙文。文章主要讲述了作者的狗失踪了,后来Erica用无人机把它找了回来。 1.C　根据上文“Suddenly, two dogs appeared, attacking him.”可知,Chester被别的狗攻击,所以它是害怕了。故选C。concerned担忧的;annoyed恼怒的;scared害怕的;confused困惑的。 2.A　根据空后的myself以及下文“…it’s like losing a family member.”可知,此处指作者说的话仅代表自己,表示宠物狗在自身生活中的重要性。故选A。speak for代表……发言;focus on专注于;turn to转向;adapt to适应。 3.B　根据上文“He got…and ran off in an unfamiliar direction.

But they found super-small clumps of aluminum atoms (铝原子团块) on the surface. The researchers were upset because these small clumps messed up the mirror. Then they realised that the clumps made colour when light hit them. They decided to turn their discovery into paint.”可知,本段主要是讲发现油漆的过程。C选项(研究人员并没有真正打算制造油漆。)能引起下文,且承接上文“Now scientists have used nanotechnology(纳米技术)to make paint with structural colour.”。故选C。 3.D　由上文“The nanoparticles don’t really produce the colour. They simply reflect back single colour.”可知,下面要说与“反射”有关的内容,D选项(它们的大小决定了反射的颜色。)能承接上文,符合文意。D项中的reflected与空前的reflect相对应。故选D。 4.E　由上文“Because the new paint doesn’t have pigments, the paint is so light that it could reduce the amount of fuel used by planes and cars.”以及下文内容可知,E选项(一般来说,覆盖一架飞机需要大约500公斤的油漆。)能承接上文,与下文形成对比,符合文意。E项中的airplane与空前的planes相对应。故选E。 5.A　由下文“Once we paint something with structural colour, it should stay for centuries.
