【正文】 of Greenland today. measure the changing temperatures by directly examining mud. holds enough ice that might one day threaten life in coastal cities.（4）Which do you think is the best title of the passage? Used to Be Much Greener Once Experienced Warm Periods Cities Warned of Coming Disasters Greenland, A Perfect Destination【答案】 （1）C（2）B（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹了在古代沉積物中發(fā)現(xiàn)的一條微小線索揭開了格陵蘭島過去和未來氣候的大秘密。就在廣闊的格陵蘭冰原的西北邊緣，研究人員發(fā)現(xiàn)了在最后一個冰河時代幸存下來的湖泥。現(xiàn)在研究人員認為，格陵蘭北部的冰蓋經(jīng)歷了比之前認為的更強烈的變暖。 （1）考查推理判斷。根據(jù)第一段中的“The mud, and remains of mon flies in it, record two interglacial periods（間冰期）in northwest Greenland.”在格陵蘭島西北部，泥漿和常見蒼蠅的殘骸記錄了兩次間冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”盡管研究人員很早就知道這兩個時期——全新世早期和最后一次間冰期——在北極經(jīng)歷了變暖，但混合的蠅類表明格陵蘭島甚至比之前認為的還要熱。可知，在前兩段中提到蒼蠅的殘骸是為了證明格陵蘭島的溫度比之前認為的要高得多。故選C。 （2）考查細節(jié)理解。根據(jù)第三段中的“This new information could help researchers better measure Greenland39。s sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. ”可知，這些新信息可以幫助研究人員更好地測量格陵蘭島對氣候變暖的敏感性。故選B。 （3）考查細節(jié)理解。根據(jù)第三段中的“After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’” 可知，格陵蘭島覆蓋了這個北極國家的80%，擁有相當(dāng)于全球海平面20英尺的冰。“格陵蘭西北部可能真的感覺很遙遠，但冰蓋的變化將關(guān)系到世界上每個沿海城市的每個人。”故選D。 （4）考查主旨大意。本文通過最新的發(fā)現(xiàn)——最后一個冰河時代幸存下來的湖泥及湖泥中的蒼蠅殘骸及其相關(guān)研究說明格陵蘭島之前可能更暖和。因此，本文的最佳標題應(yīng)為“格陵蘭島曾經(jīng)更加綠色”。故選A。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，概括歸納，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小孔的原因，且這個問題會被偶爾問到，就像如果你用核武器攻擊黃石公園會發(fā)生什么事這個問題一樣，作者是在舉例證明他的觀點，故選B。 （2）考查詞義猜測。此處意為當(dāng)使用者不慎把筆帽吞下時，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，舉行書寫測試的目的是為了確保筆能夠達到最高的標準，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。 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科普類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，
