【文章內(nèi)容簡介】 A. clearing up the space will actually cost littleB. small rockets also do harm to the atmosphereC. only robots can clear up the space pletelyD. it is still difficult for us to clear up the space【解析】選D。推理判斷題。從倒數(shù)第二段的內(nèi)容可知, 清理太空垃圾不是一件非常容易的事情, 故選D項(xiàng)。8. What is the text mainly about? A. Space junk threatens earth’s orbital environment. B. Scientists use different methods to clear up space junk. C. Spacecrafts will meet with a lot of space junk in the future. D. Marco es up with many methods to deal with space junk. 【解析】選A。主旨大意題。本文主要講的是太空中存在著許多垃圾, 這些垃圾慢慢會對地球及以后發(fā)射的太空飛船構(gòu)成威脅, 科學(xué)家們正在研究如何清理它們。故選A項(xiàng)。【技巧點(diǎn)撥】 推理判斷題往往是針對文中某一句話, 也可能是某幾句話, 從文章的表面含義挖出所隱藏的內(nèi)容, 最終推出答案。本文第2小題, 從第三段的“The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles. ”可知, 如果太空中形成了垃圾云層, 那以后發(fā)射的太空飛船就會遇到危險(xiǎn)了, 可知現(xiàn)在科學(xué)家最擔(dān)心太空垃圾會危害未來空間飛行器, A項(xiàng)正確。Ⅱ. 閱讀填句　　根據(jù)短文內(nèi)容, 從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。A New Trend of Micro MuseumsIs Making Science Portable　　Science museums are amazing. You can see large dinosaur bones from the huge creatures that disappeared thousands of years ago or take a look at cells under a microscope. 　1　. You can learn so much at a science museum if living close enough to one. However, for those who don’t live in a city, getting a chance to visit science museums is not easy. “　2　, their influence is limited. There just aren’t enough science museums, ” said Charles Philipp. “And due to the high costs, it’s unlikely that we’ll be seeing a bunch of new traditional science museums popping up all over the country anytime soon. ”Philipp and his partner Amanda Schochet have decided to reinvent science museums by getting them small. They founded MICRO, a nonprofit organization that builds tiny 6foottall science museums, which are portable and replicable (可復(fù)制的). 　3　. They can get access to it for free in such places as waiting rooms of hospitals, libraries, airports, and even shopping malls. 　4　, they made it with the help of a team of engineers, storytellers, and designers. Each of the micro museums has a scientific topic. The first museum is the Smallest Mollusk (軟體動物) Museum showing the world of mollusks, which has won great popularity as the only museum devoted just to mollusks. A second museum is the Perpetual Motion Museum that focuses on physics and engineering and will officially open next year. It asks why things move, and why they stop. 　5　Hopefully one will e to a neighborhood near you soon. A. Science museums are beneficialB. While the content is vitally importantC. Although it costs nothing to visit museumsD. The plan is to get people of all ages connected with scienceE. Even though making the tiny museums a reality was difficultF. Such new museums allow people to explore fun scientific topicsG. You can also learn to think like an engineer by building a model ship【文章大意】本文介紹了一種只有6英尺高的便捷式可復(fù)制的微型科學(xué)博物館, 它使人們更容易接觸科學(xué)博物館和學(xué)習(xí)新的科學(xué)知識。1. 【解析】選G。根據(jù)前一句“You can see large dinosaur bones from the huge creatures that disappeared thousands of years ago or take a look at cells under a microscope”和下文中的“You can learn so much at a science museum . . . one”可知, 此處應(yīng)是舉例你可以在科學(xué)博物館做的事情, 故G項(xiàng)符合語境。2. 【解析】選B。結(jié)合上文中提及博物館的好處以及下文講到“their influence is limited. There just aren’t enough science museums”可知, 空處與后半句有轉(zhuǎn)折關(guān)系, 故B項(xiàng)合適, 此處意為“盡管科學(xué)博物館的內(nèi)容非常重要, 但是它們產(chǎn)生的影響有限”。3. 【解析】選D。上文提到了Charles Philipp和Amanda Schochet決定建造微型科學(xué)博物館, 空處說明了他們建造微型科學(xué)博物館的目的, 是對前一句的進(jìn)一步闡述。4. 【解析】選E。根據(jù)上文對微型科學(xué)博物館的描述及下文“they made it with the help of a team of engineers, storytellers, and designers”可知, 建造這樣的科學(xué)博物館絕非易事, 但他們成功了, 故E項(xiàng)符合語境。5. 【解析】選F。上文主要介紹了兩種主題的微型科學(xué)博物館, 第一種以軟體動物為主題, 第二種則關(guān)注物理學(xué)和工程學(xué), 這些新型科學(xué)博物館能夠使人們了解科學(xué)方面的知識, 故F項(xiàng)符合語境。話題寫作素養(yǎng)升級描述太空生活經(jīng)歷　　假如現(xiàn)在是2050年, 你剛參加過學(xué)校組織的一次火星旅游, 請根據(jù)提示寫一篇80詞左右的短文。要點(diǎn)如下: 1. 出行方式及路線(乘航天飛機(jī)到達(dá)太空站再到達(dá)火星)。 2. 所見所聞, 如外星人(alien)。 3. 你的感受。 　　It is 2050. Our school organized a trip from the Earth to Mars. Firstly, we reached a space station by a spacecraft after a oneday journey from Earth. After a short break and then two hours later, we landed on Mars. The aliens on Mars are very kind and friendly, and what surprised us is that they speak English much better than us. There are lots of other amazing things. We even came across a talking stone. The living environment of aliens is really fortable. This is much bet
