【正文】 tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.s diameter increases as it grows, just as a person39。 t been much data on whether city trees grow, die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out. As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burningof fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe. 8．閱讀理解 故選D。它象征著解決太空垃圾這一關(guān)鍵問題的第一步。 （4）考查主旨大意。”可知，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，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?？芍瑃he 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.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. 7．閱讀理解 進(jìn)行培訓(xùn)是為了得到專業(yè)技能,由此推斷作者會(huì)給出一直提升人們的專業(yè)技能的建議,故選D。 （4）考查推理判斷。排除A；再根據(jù)第四段中的“as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors.”可知需要情感的工作,例如老師,保姆和醫(yī)生也不大可能被取代,因此排除C和D。人工智能不可能像科學(xué)家,小說家和藝術(shù)家那樣進(jìn)行發(fā)明創(chuàng)造。根據(jù)第三段中的“First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can.”可知四種類型的工作完全沒有風(fēng)險(xiǎn)。結(jié)合下文推斷人工智能能夠具有取代人類的工作是因?yàn)锳I在日常任務(wù)中表現(xiàn)超過了人類,劃線詞的意思是勝過,超過,故選A。 （2）考查詞義猜測(cè)。而后文主要與人工智能有關(guān),由此推斷作者寫第一段的目的是引出人工智能這個(gè)話題。但是,他不會(huì)說法語。根據(jù)第一段可知一個(gè)名叫奈杰爾因此,在人工智能時(shí)代人類仍然會(huì)有工作,關(guān)鍵必須是對(duì)勞動(dòng)力進(jìn)行再培訓(xùn),這樣人們才能從事這些工作。Upgrade people39。Get more support from the government.C.The psychologist.（4）Which of the following suggestions can the author give about job replacement of AI?

A.Be similar toBe inferior toBe superior toTo stress the importance of good memory.D.To mention Nigel39。So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.（1）What is the main purpose of paragraph 1? A. Are you worried that these three types of jobs won39。 But not every job will be replaced by AI. In fact impressive feat is a useful example to show how artificial intelligence works—real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.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?？v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)器人的未來發(fā)展充滿信心、非常樂觀，故選C。 performance…”可知，這臺(tái)機(jī)器人的表現(xiàn)還要經(jīng)過進(jìn)一步的測(cè)，說明正在測(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?
