【正文】 The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guiltproneness (內(nèi)疚傾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given $1, which they can choose to give to Player2. Any money given to Player 2 is then automatically increased to $. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a portion of the money to Player 1. The researchers found more guiltprone people were more likely to share the money with Player 1. Actually, in followup studies, guiltproneness predicted trustwor。 【點評】本題考點涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。第一段中的“A new study has found that there is a long history of interactions between ants and plants.”一項新的研究發(fā)現(xiàn)，螞蟻和植物之間的互動有著悠久的歷史。由此可知C選項描述正確，故選C。根據(jù)倒數(shù)第二段中的“But scientists weren39。由此可知，第二段主要講了植物和螞蟻如何互動，故選A。根據(jù)第二段中的“Plants make a number of different structures that are specific for ant use.”植物有許多不同的結(jié)構(gòu)，這些結(jié)構(gòu)是專門為螞蟻使用的；“Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds.”可知，有些螞蟻會偷取花蜜逃跑，但有些會留下來攻擊任何試圖傷害植物的東西。故選D。 （1）考查細(xì)節(jié)理解。s traditional views about plants.【答案】 （1）D（2）A（3）C（4）B 【解析】【分析】本文是一篇說明文，一項新的研究發(fā)現(xiàn)，螞蟻和植物之間的互動有著悠久的歷史。 interest in science research.D.To inform readers of a latest research finding.C.s purpose of writing the passage?

A.t sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chickenandegg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.t have to pete for resources.ll grow better, and since it39。 Plants are boring. They just sit there photosynthesizing (光合作用) while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant coevolution (協(xié)同進化) started with ants feeding on plants and plants evolving antfriendly features.7．閱讀短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項?？v觀全文可知，,作者提到無現(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,對待電子支付是客觀的,故選C。故選B。大多數(shù)金融公司都渴望放棄它,或者以高昂的費用勸阻老式客戶。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)金消失的一個重要原因就是諸如銀行和科技公司（在發(fā)達市場）和電信公司（在新興市場）之類的供應(yīng)商正在開發(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。故選C。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,數(shù)字支付從2012年占所有支付的4％上升到2017年的34％。故選D。根據(jù)第一段中的“Rich countries are racing to dematerialise payments.”可知, 富裕國家正競相將支付非物質(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.”在過去的十年中,瑞典的人均零售現(xiàn)金交易數(shù)量下降了80％?？偟膩碚f,無現(xiàn)金經(jīng)濟的未來是個好消息,但是對于電子支付人們也有一些擔(dān)憂。D.C.B.. A.s attitude towards digitalized payment is the infrastructure is developing at a high speed in developed marketsD.younger consumers are short of money to live their digital livesB.China is developing faster that those developed countries in digital payment（3）Cash is disappearing largely because that cash is still king across the worldC.. A.promote payment without paper money or coins（2）In paragraph 3, several countries are mentioned to show get rid of the sideeffects of cashC.. A. Yet set against these benefits are a couple of worries. Electronic payment systems may risk technical failures, power failure and cyberattacks. In a cashless economy the poor, the elderly and country folk may be left behind. And a digital system could let governments watch over people39。 Cash is dying out because of two forces. One is demand— younger consumers want payment systems that plug easily into their digital lives. But equally important is that suppliers such as banks and tech firms (in developed markets) and teles panies (in emerging ones) are developing fast, easytouse payment technologies from which they can pull data and pocket fees. There is a high cost to running the infrastructure behind the cash economy—ATMs, vans carrying notes, tellers who accept coins. Most financial firms are keen to abandon it, or discourage oldfashioned customers with heavy fees. For the past 3,000 years, when people thought of money they thought of cash. Over the past decade, however, digital payments have taken off— tapping your plastic on a terminal or swiping a smartphone has bee normal. Now this revolution is about to turn cash into an endangered species in some rich economies. That will make the economy more efficient—but it also causes new problems that could hold back the transition(轉(zhuǎn)型).6．閱讀理解 根據(jù)最后
