【正文】 0。C.objectiveD.indifferent【答案】 （1）D（2）C（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，富裕國(guó)家正在減少現(xiàn)金支付,現(xiàn)金正在因?yàn)樾枨蟮仍蛳??？偟膩?lái)說(shuō),無(wú)現(xiàn)金經(jīng)濟(jì)的未來(lái)是個(gè)好消息,但是對(duì)于電子支付人們也有一些擔(dān)憂。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“Rich countries are racing to dematerialise payments.”可知, 富裕國(guó)家正競(jìng)相將支付非物質(zhì)化；再根據(jù)第三段中的“In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years.”在過(guò)去的十年中,瑞典的人均零售現(xiàn)金交易數(shù)量下降了80％。結(jié)合上下文,可知某些富裕國(guó)家比如瑞典正在減少現(xiàn)金支付,推廣不用紙幣或硬幣的支付方式,也就是電子支付方式。故選D。 （2）考查推理判斷。根據(jù)第三段中的“In Sweden the number of retail cash transaction per person has fallen by 80% in the past ten years.”可知在過(guò)去的十年中,瑞典的人均零售現(xiàn)金交易數(shù)量下降了80％；再根據(jù)“In China digital payments rose from 4% of all payments in 2012 to 34% in 2017.”可知在中國(guó),數(shù)字支付從2012年占所有支付的4％上升到2017年的34％。瑞典和中國(guó)的共同點(diǎn)是現(xiàn)金支付減少,電子支付比例上升,由此可推斷作者提到瑞典和中國(guó)是為了說(shuō)明數(shù)字支付正成為一種不可阻擋的趨勢(shì)。故選C。 （3）考查推理判斷。根據(jù)第四段中的 “But equally important is that suppliers such as banks and tech firms (in developed markets)... Most financial firms are keen to abandon it, or discourage oldfashioned customers with heavy fees.”可知現(xiàn)金消失的一個(gè)重要原因就是諸如銀行和科技公司（在發(fā)達(dá)市場(chǎng)）和電信公司（在新興市場(chǎng)）之類(lèi)的供應(yīng)商正在開(kāi)發(fā)快速,易于使用的支付技術(shù),他們可以從中提取數(shù)據(jù)和小費(fèi)。運(yùn)行現(xiàn)金經(jīng)濟(jì)背后的基礎(chǔ)架構(gòu)需要付出高昂的成本,這些基礎(chǔ)設(shè)施包括自動(dòng)取款機(jī),載有紙幣的貨車(chē),接受硬幣的出納員。大多數(shù)金融公司都渴望放棄它,或者以高昂的費(fèi)用勸阻老式客戶(hù)。也就是供應(yīng)商為了減少成本,獲取數(shù)據(jù)和小費(fèi),開(kāi)發(fā)了更便捷的支付方式,導(dǎo)致現(xiàn)金支付的減少。故選B。 （4）考查推理判斷?？v觀全文可知，,作者提到無(wú)現(xiàn)金支付即電子支付的好處,也提到電子支付引起的擔(dān)憂,對(duì)待電子支付是客觀的,故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科技類(lèi)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。7．閱讀理解 Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。re being eaten alive within minutes of stepping outdoors. If this is you, you39。re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 mouths water? A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can39。t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆蟲(chóng)學(xué)) at the University of Florida in the US, told NBC it39。s not plicated. The two most important reasons a mosquito is attracted to you have to do with sight and smell. Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻擊對(duì)象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That39。s why you monly find them in crowded streets and parks. Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (濃度). As a result, people who simply exhale (呼出) more of the gas over time – generally, larger people – have been shown to attract more mosquitoes than others. This is why kids don39。t get bitten as much ... as adults, US professor Ted Rosen told Science Alert. This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren39。t pregnant. In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting mosquitoes. According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (視覺(jué)), people wearing dark colors are more likely to bee targets. Being bitten by mosquitoes is annoying, but don39。t worry. Some simple tips can help ward them off. Scientists remend that we use insect repellent (驅(qū)蟲(chóng)劑) and wear lightcolored clothing.（1）How do mosquitoes locate their targets, according to the article? seeking out bright clothes. identifying different blood types. sensing an increase of carbon dioxide. following bigger crowds.（2）Why are pregnant women more likely to be bitten by mosquitoes? larger size helps mosquitoes to see them. breathe out more CO2. are more likely to sweat. body temperatures are higher.（3）How does the article advise you to avoid mosquitoes? regularly. lightcolored clothing. your skin dry and clean. indoors in the evening.（4）What39。s the article mainly about? new finding about mosquitoes. people can avoid mosquito bites. popular myth about mosquitoes. some people are more attractive to mosquitoes than others.【答案】 （1）C（2）B（3）B（4）D 【解析】【分析】本文是一篇說(shuō)明文，介紹了為什么有些人可以整個(gè)夏天坐在戶(hù)外乘涼卻不被蚊子叮咬，而有些人一出門(mén)就好像要被蚊子吃掉一樣。 （1）考查細(xì)節(jié)理解。根據(jù)第四段中的“While flying along, they use their sense of smell to find possible targets. They find victims by smelling the carbon dioxide (CO2) breathed out by humans and animals. ”飛的時(shí)候，它們用嗅覺(jué)發(fā)現(xiàn)目標(biāo)。它們通過(guò)聞人和動(dòng)物呼出的二氧化碳來(lái)鎖定目標(biāo)；以及第五段中的“Mosquitoes start orienting themselves to carbon dioxide and keep flying upwind as they sense higher concentrations”蚊子開(kāi)始飛向有二氧化碳的地方，當(dāng)它們感知到高濃度的二氧化碳時(shí)，就保持逆流飛行，可知，蚊子通過(guò)感知二氧化碳的增加來(lái)鎖定目標(biāo)。故選C。 （2）考查細(xì)節(jié)理解。根據(jù)第七段“This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren39。t pregnant.”對(duì)二氧化碳的喜歡使得孕婦很容易被蚊子咬，因?yàn)樗齻儽日Ｏ嗤挲g，相同體型的人呼出多余21%的二氧化碳，可知，孕婦呼出更多的二氧化碳，所以更招蚊子咬。故選B。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段中的“Scientists remend that we use insect repellent and wear lightcolored clothing.”科學(xué)家建議我們使用驅(qū)蟲(chóng)劑或者穿淺顏色的衣服?？芍?，文章建議我們可以通過(guò)穿淺色衣服來(lái)避免蚊子叮咬。故選B。 （4）考查主旨大意。根據(jù)第二段中的“According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 mouths water?”根據(jù)Smithsonian雜志，世界上大約20%的人容易招蚊子咬。為什么這些人非常吸引蚊子呢？可知，本文探討的話題是：為什么一些人比其他人更容易招蚊子。故選D。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和主旨大意兩個(gè)題型的考查，是一篇科研類(lèi)閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行概括和歸納，從而選出正確答案。8．閱讀理解 Benefits and Problems of Genetic Engineering Plant breeding is the science of changing the characteristics of plants in order to produce desired ones. Genes in a plant are what determine what type of characteristics it will have. Plant breeders try to create a specific oute of plants and potentially new plant varieties by changing the genes of the plants through breeding, which is making new plants from parents of different varieties or species. Actually, plant breeding has been practiced for thousa
