【正文】 wing might serve as the best title of the passage? A.A famous camouflage strategyB.Metallic iridescent as the best disguiseC.Colors unique to animalsD.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(niǎo)、孔雀，甚至在某些蝴蝶或魚(yú)類(lèi)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(niǎo)類(lèi)進(jìn)行實(shí)驗(yàn)，這些鳥(niǎo)類(lèi)的飲食中經(jīng)常含有彩虹色的昆蟲(chóng)。實(shí)驗(yàn)?zāi)康氖强纯带B(niǎo)類(lèi)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(niǎo)類(lèi)不受彩虹色昆蟲(chóng)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(lèi)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 A new study suggests a link between exposure to greenery and reduced desires for alcohol cigarette and junk food. The study is the first to investigate the possible relationships between exposure to nature and desires and negative emotions. Researchers at the University of Plymouth39。s School of Psychology surveyed 149 respondents (應(yīng)答者) aged 21 o 65 about the proportion( 比例 )of green space in their neighborhood, the presence of green views from their home, their access to a garden and how often they use public green space. The study also asked questions about experiences with depression and anxiety, as well as desires for things like caffeine, alcohol and nicotine. Participants rated the intensity( 強(qiáng)度), imagery, and intrusiveness(侵?jǐn)_性) of their desires on an 11point scale. Researchers found the presence of visible green space contributed to decreased desires for junk food. The effect was particularly noticeable when more than 25 percent of a respondent39。s view was greenery. Previous scholarship(學(xué)術(shù)研究) has dealt mostly with exercise in nature: A 2015 study out of the University of Michigan found 90 minute group nature walks were effective at batting depression and relieving other mood disorders. But for people who struggle with accessibility or don39。t have time for a 90minute walk, this new study suggests just looking out a window at a tree can help fight off a bad habit. It has been known for some time that being outdoors in nature is linked to a person39。s wellbeing, lead author Leanne Martin said in a statement. But for there to be a similar association with desires from simply being able to see green space adds a new dimension to the previous research. A 2018 study from Denmark39。s Aarhus University for example, found that. Having access to green space throughout childhood decreased a person39。s risk of developing mental health problems as an adult.（1）What does the second paragraph mainly talk about? results of the new study. purpose of the new study. significance of the new study. content of the new study.（2）What does the underlined word batting in paragraph 4 probably mean? ...（3）According to the passage, the new study _____. referred to exercise in nature enriched the previous research to some degree carried out by the University of Michigan exposure to greenery helped cure mental problems（4）n which section of a newspaper may this passage appear? World amp。Science【答案】 （1）D（2）A（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了一項(xiàng)新的研究成果多看綠色植物和吃垃圾食品這兩者看似風(fēng)馬牛不相及，可研究結(jié)構(gòu)卻表明它們之間存在著一種奇妙的關(guān)系：多看綠色植物能幫助人們克制吃垃圾食品的欲望。 （1）考查段落大意。根據(jù)第二段中的“Researchers …surveyed 149 respondents aged 21 o 65 about the proportion of green space in their neighborhood…”研究人員調(diào)查了年齡在21~65歲之間的149名參與者小區(qū)內(nèi)的綠植比例……；以及“The study also asked questions about experiences with depression and anxiety…”研究中還問(wèn)了與抑郁及焦慮有關(guān)的問(wèn)題……等可知，第二段主要介紹了新研究的調(diào)查內(nèi)容，故選D。 （2）考查詞義猜測(cè)。根據(jù)常識(shí)可知，在大自然中散步對(duì)人體有各種各樣的好處，再結(jié)合句中出現(xiàn)的“relieving other mood disorders(緩解其他情緒紊亂)”不難推斷出， batting depression應(yīng)表示“減輕抑郁”。故選A。 （3）考查細(xì)節(jié)理解。根據(jù)倒數(shù)第二段中的“…adds a new dimension(方面) to the previous research”為以前的研究增加了新的方面，可知，新的研究在某種程度上豐富了之前的研究成果。故選B。 （4）考查推理判斷。縱觀全文可知，本文介紹了一項(xiàng)科學(xué)研究的研究成果，所以該文章最有可能出現(xiàn)在“技術(shù)與科學(xué)”版塊。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)，推理判斷和段落大意四個(gè)題型的考查，是一篇科研類(lèi)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。8．閱讀短文，從每題所給的A、B、C和D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。 Moving smoothly and silently through Alibaba Group Holding Ltd39。s futuristic FlyZoo hotel, black discshaped robots about a metre in height deliver food and drop off fresh towels. The robots are part of a set of hightech tools that Alibaba says strongly cuts the hotel39。s cost of human labour and eliminates the need for guests to interact with other people. Formally opened to the public last month, the 290room FlyZoo is an incubator for technology Alibaba wants to sell to the hotel industry in the future and an opportunity to showcase its prowess in artificial intelligence. It is also an experiment that tests consumer fort levels with unmanned merce in China. Inside the hotel, softlylit white panelled walls bring to mind the interiors of Hollywood spaceships. Guests check in at podiums that scan their faces, as well as passports or other ID. Visitors with a Chinese national ID can scan their faces
