Did you know, for example, that each Bic ballpoint pen can produce at least 2 kilometers ( miles) of ink before it begins to run out? In fact, in 2018, 7,250 kilometers (4,505 miles) of writing tests on such pens were carried out on ballpoint pens, gel pens(中性筆), and rollers to make sure they worked to the highest standard.That39。s website, under their FAQs (frequently asked questions), it quite clearly states: The reason that some BIC174。 s one of those things that e up from time to time, like what would happen if you attack Yellowstone with a nuclear weapon (not much, as it turns out).t choke to death.

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。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。 （1）考查推理判斷。A science report.【答案】 （1）B（2）C（3）D（4）D 【解析】【分析】本文是一篇說(shuō)明文，登山者報(bào)告說(shuō)看到一只長(zhǎng)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。A travel brochure.A climbing guide.A science fiction.Whether they are willing to wear backpacks and face masks.D.Whether they have super hearts and lungs.B.The geese could live through the lowest concentration of oxygen.D.It was carried out at very high altitude.B.To observe them flying through the wind tunnel.D.To test the flying height and speed of them.B. 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。 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。 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.6．閱讀理解 故選D。 （4）考查推理判斷。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(yáng)能熱燃料(STF)，以前就已經(jīng)被開(kāi)發(fā)出來(lái)了，可知，STF是以化學(xué)反應(yīng)為基礎(chǔ)。故選D。 （2）考查細(xì)節(jié)理解。或者，再想象一下車的擋風(fēng)玻璃可以儲(chǔ)存太陽(yáng)的能量，然后釋放熱量使擋風(fēng)玻璃上的冰消失)可推測(cè)，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(lái)吸引對(duì)著對(duì)本文的興趣。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。 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(shuō)明文，介紹了一種新型材料，它可以通過(guò)自身吸熱并儲(chǔ)存熱量，之后能夠根據(jù)需要釋放熱。 The key to enabling longterm, stable storage of solar heat, the team said, is to store it in the form of a chemical 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.Solar energy is only available about half the time we need it — during daylight. For the sun to bee a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun39。 s energy and then releases it as heat to make the ice on the windshield disappear. 5．閱讀理解 故選D。根據(jù)最后一段中的”If Mr Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind. “如果霍華德和其他人如愿以償，那么讓AI軟件開(kāi)發(fā)變得更容易將會(huì)催生出一批新的不同的果實(shí)。故選A。僅需要中學(xué)數(shù)學(xué)知識(shí)。讓任何想學(xué)習(xí)編寫(xiě)AI軟件的人都能學(xué)習(xí)這門技術(shù)。根據(jù)五段中的”To make it accessible to anyone who wants to learn …He says school mathematics is sufficient.“可知讓深度學(xué)習(xí)不再神秘是杰里米也就是說(shuō)fast. ai是一個(gè)提供深度學(xué)習(xí)課程的組織，故選C。根據(jù)第四段中的”Last month fast. ai, a nonprofit education organization based in San Francisco, kicked off the thir
