【正文】 0。D.Shining colors as a sexual strategy【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】本文是一篇說(shuō)明文，介紹了彩虹色有助于生物隱藏。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被動(dòng)物用來(lái)通過(guò)逃離捕食者而活得更久，排除A；根據(jù)第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在這里我想指出的是，在某些物種中，尤其是那些表現(xiàn)出強(qiáng)烈兩性差異的物種，比如天堂鳥、孔雀，甚至在某些蝴蝶或魚類中，彩虹色的出現(xiàn)很可能是由性別選擇所驅(qū)動(dòng)的?？芍?jiǎng)游镉貌屎缟鹜榈淖⒁?，排除B；根據(jù)倒數(shù)第二段中的“The idea that eye173。catching colors could be used as a cover173。up isn39。t a new one.”引人注目的顏色可以用來(lái)偽裝，這種想法并不新鮮，排除C，故選D。 （2）考查細(xì)節(jié)理解。根據(jù)最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我們的目標(biāo)上驚人的彩虹表面在視覺(jué)上打破了原本可以辨認(rèn)的目標(biāo)形狀，這使得它們很難區(qū)分。故選C。 （3）考查推理判斷。根據(jù)最后一段說(shuō)研究人員目前正在對(duì)鳥類進(jìn)行實(shí)驗(yàn)，這些鳥類的飲食中經(jīng)常含有彩虹色的昆蟲。實(shí)驗(yàn)?zāi)康氖强纯带B類的視角是否能提供幫助。由此推斷接下來(lái)一段會(huì)談?wù)?為什么鳥類不受彩虹色昆蟲的影響，故選C。 （4）考查主旨大意。第一段中的“Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”有時(shí)，最好的偽裝其實(shí)是最耀眼的偽裝，因?yàn)檠芯勘砻?，閃光的金屬彩虹色能在視覺(jué)上迷惑捕食者，這讓五顏六色的獵物能夠再存活一天，是全文的主題句，結(jié)合全文內(nèi)容，可知這篇文章主要講了彩虹色有助于生物隱藏，故選B。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，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(shuō)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(wèn)題會(huì)被偶爾問(wèn)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(wèn)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
