【正文】 s initial attitude towards tidal power? ....（3）What are the locks。The tidal power station has been built there.D.The tidal range there is about 15 meters.B. But there would be nothing old fashioned about Mr Rainey39。 Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306 521) per MWh of electricity by 2025, pared with ￡58 75 for seagoing wind turbines (輪機(jī)) and ￡55 76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.7．閱讀理解 故選D。它象征著解決太空垃圾這一關(guān)鍵問(wèn)題的第一步。 （4）考查主旨大意?！笨芍?，劃線詞的意思是“支持”。根據(jù)最后一段中的”Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.“Aglietti說(shuō)，他希望清理碎片的工作每年能進(jìn)行幾次，目標(biāo)是最擁擠軌道上最大的垃圾碎片。故選A。它可以瞄準(zhǔn)大塊的垃圾，包括長(zhǎng)達(dá)10米的報(bào)廢衛(wèi)星。 （2）考查推理判斷。可知，the RemoveDEBRIS衛(wèi)星的用途是收集太空中存在的廢物。 （1）考查細(xì)節(jié)理解。Satellite Collects Space Junk for the First Time【答案】 （1）C（2）A（3）B（4）D 【解析】【分析】本文是一篇說(shuō)明文，介紹了“衛(wèi)星首次收集太空垃圾。How RemoveDEBRIS Is Invented in the LabC.s the best title for the text? A.D.C.B.By targeting large pieces of junk carefully.（3）What does the underlined word sponsor in the last paragraph probably mean? A.By fastening it to the main satellite tightly.C.Symbolizing great progress in space.（2）How does the RemoveDEBRlS satellite work? A.Imitating a developing technique.C.Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said The challenge will lie in persuading the relevant authorities to sponsor these tasks. Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.（1）What is the use of the RemoveDEBRIS satellite? A. s experiment was exciting, but he cautioned against over publicizing it. Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.s Surrey Space Center and includes Airbus, Airbusowned Surrey Satellite Technology Ltd. and France39。 Various panies have plans to send thousands of new satellites into lowEarth orbit, already the most crowded area. The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space. 6．閱讀理解 performance ”可知，機(jī)器人目前還在華盛頓州立大學(xué)的智能屋里進(jìn)行測(cè)試，故選B。縱觀全文可知，本文介紹了一款由美國(guó)華盛頓州立大學(xué)的科學(xué)家們研發(fā)的機(jī)器人。根據(jù)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(duì)這款機(jī)器人的未來(lái)發(fā)展充滿信心、非常樂(lè)觀，故選C。 performance…”可知，這臺(tái)機(jī)器人的表現(xiàn)還要經(jīng)過(guò)進(jìn)一步的測(cè)，說(shuō)明正在測(cè)試階段，故選B。 （2）考查推理判斷。 （1）考查細(xì)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. 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.5．閱讀理解 You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup ”你能在全世界買(mǎi)Bird Friendly 認(rèn)證的咖啡，每杯都保護(hù)野生動(dòng)物和棲息地，故選C。 （4）考查推理判斷。根據(jù)第三段中的“ The wood and fruit trees on shade coffee farms provide farmers with additional ine.故選A。根據(jù)第二段中的“ 根據(jù)第一段中的“ In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification. ”可知，科學(xué)家們重視咖啡生長(zhǎng)地的問(wèn)題，并以想出應(yīng)對(duì)辦法，故選D。Donate to coffee farmers.【答案】 （1）D（2）A（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，為了應(yīng)對(duì)嚴(yán)重的遷徙鳥(niǎo)類的數(shù)量和棲息地?fù)p失，史密森尼的科學(xué)家創(chuàng)造了 the Bird Friendly certification 。Order coffee online.C.Consume less coffee.D.By selling fruits and wood from trees.C.They are grown on unpolluted land.（3）How can Bird Friendly farmers earn more money?
