【正文】 change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (觸發(fā))by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process. imagination. interest readers in the passage. introduce a new kind of material.（2）According to the passage, what can the polymer film do? can be made into window glass. can make necessary electricity. can store energy and release sunshine. can absorb sunshine and give off heat.（3）According to the passage, what is STF based on? chemical reaction. movement of heat. form of electricity. physical reaction.（4）What is the advantage of the molecular configuration? is less expensive. is very powerful. is easily available. is less changeable.【答案】 （1）C（2）D（3）A（4）D 【解析】【分析】本文是一篇說明文，介紹了一種新型材料，它可以通過自身吸熱并儲(chǔ)存熱量，之后能夠根據(jù)需要釋放熱。根據(jù)第一段“Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay fortable in a cooler room. Or, picture a car windshield that stores the sun39。或者，再想象一下車的擋風(fēng)玻璃可以儲(chǔ)存太陽的能量，然后釋放熱量使擋風(fēng)玻璃上的冰消失)可推測，本段以衣服和騎車擋風(fēng)玻璃為例，提到了如果衣服能夠吸熱和放熱、汽車的擋風(fēng)玻璃能夠吸熱和自動(dòng)除冰那該是多么好的事，以此來吸引對(duì)著對(duì)本文的興趣。 （2）考查細(xì)節(jié)理解。故選D。根據(jù)最后一段中的“Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. ”這種以化學(xué)反應(yīng)為基礎(chǔ)的儲(chǔ)存材料，即太陽能熱燃料(STF)，以前就已經(jīng)被開發(fā)出來了，可知，STF是以化學(xué)反應(yīng)為基礎(chǔ)。 （4）考查推理判斷。故選D。6．閱讀理解 The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模擬)10w, medium, and highaltitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel. The wind tunnel experiments showed that when the concentration of oxygen was at its lowestlike the 7% found on top of Mount Everest versus 21% at sea level—the geese39。 Although well trained, the birds were only willing to stay in the air a few minutesor less when wearing their backpacks and flying at 6ihigh altitudes. So it39。To test the flying height and speed of them.B.To observe them flying through the wind tunnel.D.It was carried out at very high altitude.B.The geese could live through the lowest concentration of oxygen.D.Whether they have super hearts and lungs.B.Whether they are willing to wear backpacks and face masks.D.A science fiction.A climbing guide.A travel brochure.A science report.【答案】 （1）B（2）C（3）D（4）D 【解析】【分析】本文是一篇說明文，登山者報(bào)告說看到一只長頸鵝翱翔在珠穆朗瑪峰的頂峰，為了確認(rèn)其真實(shí)性，研究人員養(yǎng)了18只這種鵝，在大型風(fēng)洞中訓(xùn)練它們飛行。 （1）考查推理判斷。人們認(rèn)為這是不可能的；以及 Now researchers who raised 19 of the geesenamed for the black stripes on the backs of their headshave shown the birds really fly so high.現(xiàn)在研究人員飼養(yǎng)了這種鵝，他們發(fā)現(xiàn)這些鵝真的飛得很高。s not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.但是否能讓這種鵝飛8小時(shí)爬上珠穆朗瑪峰尚不清楚。故選B。根據(jù)第四段中的The wind tunnel experiments showed that when the concentration of oxygen ...the geese39。研究人員今天在《伊利費(fèi)》雜志上報(bào)道說，...這種降溫可能有助于補(bǔ)償空氣的稀??；第五段中的Although well trained, the birds were only willing to stay in the air a few minutesor less ... 盡管訓(xùn)練有素，但這些鳥只愿意在空中呆上幾分鐘。故選C。根據(jù)最后一段中的So it39。故選D。第一段中提到登山者報(bào)告說看到一只長頸鵝翱翔在珠穆朗瑪峰的頂峰。結(jié)果發(fā)現(xiàn)這種鵝可以在氧氣極低的情況下飛行，但停留時(shí)間只有幾分鐘，因此能否飛過珠峰尚不明確。故選D。7．閱讀理解 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. Various panies have plans to send thousands of new satellites into lowEarth orbit, already the most crowded area. s Surrey Space Center and includes Airbus, Airbusowned Surrey Satellite Technology Ltd. and France39。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 experiment was exciting, but he cautioned against over publicizing it. 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.Imitating a developing technique.C.Symbolizing great progress in space.（2）How does the RemoveDEBRlS satellite work? A.By fastening it to the main satellite tightly.C.By targeting large pieces of junk carefully.（3）What does the underlined word sponsor in the last paragraph probably mean? A.B.C.D.s the best title for the text?
