【正文】 兩處綜合推斷出，鵝可以在最低濃度的氧氣中生存。故選C。 （3）考查推理判斷。根據(jù)最后一段中的So it39。s not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. 可知，目前尚不清楚的是，只有這些適應(yīng)性變化能否可以飛行8小時(shí)爬上珠穆朗瑪峰。故選D。 （4）考查推理判斷。第一段中提到登山者報(bào)告說看到一只長(zhǎng)頸鵝翱翔在珠穆朗瑪峰的頂峰。為了證實(shí)是否可能，研究人員養(yǎng)了18只這種鵝，并在大型風(fēng)洞中訓(xùn)練它們飛行。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。由此可知本文屬于科普文章。故選D。 【點(diǎn)評(píng)】本題考點(diǎn)涉及推理判斷題型的考查，是一篇科研類閱讀，要求考生根據(jù)上下文進(jìn)行分邏輯推理，從而選出正確答案。7．閱讀理解 Some things should just be mon knowledge by now. The Earth isn39。t flat. Nope, your hair and nails don39。t grow after you die. The holes at the top of Bic biro pens are there so that, if you swallow one accidentally, you can still breathe and won39。t choke to death. It39。s debatable whether that last one there is mon knowledge or not. A quick Google search of the fact, rewritten as a question, shows articles addressing this point going back several years, with the latest (re)appearing just this week over on ScienceAlert. We suppose it39。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). If you jump over to Bic39。s website, under their FAQs (frequently asked questions), it quite clearly states: The reason that some BIC174。 pens have a hole in their cap is to prevent the cap from pletely obstructing the airway if accidentally breathed in. This is requested by the international safety standards ISO11540, except for in cases where the cap is considered too large to be a choking risk. That39。s rather lovely of them. In appreciation of their want to not kill off their more clumsy customers, we thought we39。d share a few more random facts about Bic that are probably going to e up in a pub quiz one day. 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. The best part of the Bic site, however, is this rather curious fact: 100 percent of pen balls are made through a highlycontrolled process. As opposed to a highly uncontrolled process, involving explosions and bouncy castles and total chaos, we suppose.（1）Why does the author mention the case of Yellowstone? A.To list the facts.B.To prove his point.C.To pare the two situations.D.To emphasize the importance of safety.（2）What does the underlined word obstructing in paragraph 2 mean? A.Block.B.Open.C.Transform.D.Narrow.（3）Why were the writing tests on pens carried out? A.To work out their lifespan.B.To assure their good quality.C.To prove some random facts.D.To pare different pens with each other.（4）In what tone does the author develop the text? A.Critical.B.Acid.C.Humorous.D.Serious.【答案】 （1）B（2）A（3）B（4）C 【解析】【分析】本文是一篇說明文，畢克筆的筆帽上有一個(gè)小孔是為了防止那些粗心的使用者不小心吞下而窒息死亡。這真是粗心使用者的生命通道。 （1）考查推理判斷。畢克筆的筆帽上留一個(gè)小孔的原因，且這個(gè)問題會(huì)被偶爾問到，就像如果你用核武器攻擊黃石公園會(huì)發(fā)生什么事這個(gè)問題一樣，作者是在舉例證明他的觀點(diǎn)，故選B。 （2）考查詞義猜測(cè)。此處意為當(dāng)使用者不慎把筆帽吞下時(shí)，筆帽上的小孔就是為了阻止筆帽完全阻塞氣管而引起窒息，故選A。 （3）考查細(xì)節(jié)理解。根據(jù)第三段中的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.可知，舉行書寫測(cè)試的目的是為了確保筆能夠達(dá)到最高的標(biāo)準(zhǔn)，故選B。 （4）考查推理判斷。根據(jù)第一段中的Some things should just be mon knowledge by now. The Earth isn39。t flat. Nope, your hair and nails don39。t grow after you die. 和第三段中的That39。s rather lovely of them. In appreciation of their want to not kill off their more clumsy customers等作者的行文措辭可知，作者筆調(diào)輕松幽默，故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和推理判斷三個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。8．閱讀理解 It is the ideal way for traveler to ensure they wake up with the perfect view — a portable Ecocapsule that can be set up anywhere in the world. The eggshaped pod (獨(dú)立艙) ensures travelers can camp in the most extreme corners with all the luxury of a hotel room. Looking like something in a scifi movie, the pod is equipped with solar panels, which guarantee solar energy as its power. In this way the tiny home can let you live fortably wherever you travel. It even has its own shower and toilet, sleeping area for two, and a small kitchen. The 3,306 ib pods can be transported in a seacontainer, meaning the possibilities are endless. Bratislavabased Nice Architects are behind the extraordinary Ecocapsules and said they initially designed them for people who stay in the nature for a long time. However, it quickly became apparent that they could be opened up to the wider public and even used in urban areas to fight against high rent and placed on roofs for studio space or living quarters. The Ecocapsule can serve as a cottage, a popup hotel or even as a charging station for electric cars.The Ecocapsules could even be quickly imported for housing for emergency teams who have been quickly arranged to help with natural disasters.
