Poets,songwriters and politicians hate the idea,but for decades opinion-poll evidence has been clear:money buys happiness and the richer you are,the more likely you are to express satisfaction with your life.Until now,a survey of43 countries 1 on October 30th by the Pew Research Centre of Washington,DC,shows that people in 2 markeis are expressing almost the same level of satisfaction as people in rich countries.It is the biggest 3 to the standard view of happiness and income seen 4.The Pew poll asks respondents to 5,on a scale from zero to ten,how good their lives are.(Those who say between seven and ten are counted as 6.)In 2007,57%of respondents in rich countries put themselves in the top four tiers;in emerging markets the 7 was 33%;in poor countries only 16%-a classic 8 0f the standard view.But in 2014,540/o of rich-country respondents counted themselves as happy,whereas in emerging markets the percentage 9 t0 51%.This was happening just at a time when emerging markets'chances of converging economically 10 the West seemed to be 11.Rich countries did not experience 12 declines in happiness.The decreases in America and Britain were tiny(a single percentage point),13 the share of h8ppy Gennans rose 13 points.A large drop in formerly joyful Spain ensured a modest overaU decline for the rich.14 the convcrgence happened 15 huge improvements in countries such as Indonesia and Pakistan.In 12 of the 24 emerging markets,half or more people 16 their life satisfaction in the top tiers of the ladder.This is not t0 17 the link between income and satrsfaction has been snapped.Poor countries still 18:only a quarter of the people there are in the happy tiers-half the level of the other'two groups.There is 19 a clear link between happiness and income growth.China's GDP rose at an annual average rate of 10%in 2007-2014 and its happiness level rose 26 points.20 countries,richer people express more satisfaction than their poorer neighbours.13选?

Text 3 Olivia Pedersen thought the Nissan Leaf parked outside her favourite lunch spot near Emory University,must be hers.But she could not open the door.Nor could she open the door of the identical Leaf behind it.Cautiously,she tried the third Leaf in line and happily drove away.More than 14,000 electric vehicles are now registered in Georgia;California is Lhe only state with more.But the juicy state incentives for buying ihem are coming under aUack.Residents can claim an income-tax credit for 20%of the cost of leasing or purchasing an electric vehicle,up to$5,000.Combined with a possible federal tax incentive worth$7,500,savvy Georgians are driving all the way to the bank in nearly-free electric cars.Nissan sells more of its Leaf models in Adanta than in any other city,according to Don Francis from Georgia,which promotes the use of cars like these.Such trends motivated Chuck Martin,a representative in Georgia's House,to sponsor a bill to end state incentives for electric vehicles.He argues that the income-tax credit costs too much-about$13.6m in 2013-and that only urban types benefit from these sorts of cars.Mr Martin's bill was voted down in committee in February,but seems to be still breathing.Another House bill,mostly to finance transport projects,would reduce the credits;it is now before the Senate.Fans of electric vehicles say Ceorgia now leads the country in clean transport.Local power companies have helped by offering off-peak prices of l.3 cents per kilowatt hour for charging the cars at night.And the sales tax levied on this power stays in the state,whereas cash spent on petrol largely goes elsewhere,says Jeff Cohen,founder of the Atlanta Electric Vehicle Development Coalition.Cutting the credits alLogether might also harm Georgia in other ways.A study by Keybridge Public Policy Economics,a consultancy,says the stale could lose$252m by 2030 if they disap-pear and people buy gas-guzzlers instead.That is because drivers will spend$714m on petrol to get around(in contrast with the$261m they would have paid in electricity bills),and will no longer fritter away their savings from the federal electric-vehicle tax crediL in Georgia's shops.But the state's incentives may be safe in the legislature after all;the president of the Senate drives an electric car himself.A study suggests that cutting the credits in Georgia might______

动物震前预兆知识 蒋锦昌 一个大地震前往往会有多种动物出现异常行为反应,其中,鸡、狗、猫、猪、兔、羊、牛、马、鼠和鱼等较为多见,蛙、蛇和鼬等也有不少的震例记载,这也许与人们生活关系的密切性有关。地震前的动物异常行为以惊恐性行为反应为主,是物种进化过程中为逃避灾难性事件所获得的非特异性本能行为。因此,地震、火山、海啸和风暴等灾难性自然事件之前,某些动物所出现的异常行为模式是基本相似的。同时,天气变化、污染、天敌和人为扰动,及其自身的机能状态的变化,如发病、求偶、怀孕、哺乳和恶习发作等,也同样可出现类似的行为活动。地震,尤其强烈地震是小概率事件,不可能由自然选择的方式,形成某种专门对地震敏感的物种或个体,乃至某种感知地震前兆信息的特异性检测系统,更不可能产生某种反射性学习或某种经验的积累。因此,科学地排除干扰和识别真假异常是极其重要的,既可避免不必要的惊慌,也可不失去有用的前兆现象。我们之所以说地震前动物异常行为事件与地震有关,是指相当数量异常事件的统计概念,并非指某一起异常事件。换言之,地震前动物异常行为事件出现时间和地区的分布、反应强度与未来地震的三要素(发震时间、地点和震级)之间,具有一定的统计关系,这已被许多震例资料所证实。其中,在前兆时间里,动物异常行为事件是地震的一种短临前兆现象.即主要或集中出现在地震前一天之内,也有短至几分钟的,长至数天或十几天的。 当然有一些特殊现象是否与地震有关,还是巧合,尚待进一步观察研究。例如,1976年7月28日唐山大地震前,抚宁县坟坨公社徐庄大队。7月25日上午10时许,20余人目睹黄鼠狼成群结队从村北一堵古墙里跑出来,向村里大转移。当晚8时许,无处藏身的十余只黄鼬,绕核桃树乱转,当场被打死五只。夜间,这批转移到村里的黄鼬号叫不息。7月26日27日,这批黄鼬又从村里向村外树林里转移。这一现象在当时曾引起村里人的纷纷议论。 事实上,唐山大地震中,有些幸存者是得到宏观异常现象的警示而逃生,并进行自救的。据震后考察,唐山地震前出现异常现象的动物有30余种,2202起异常事件。其中,有45起目睹者看到动物异常现象后认为可能要发生地震,有的采取了一定的防震措施,如搬出屋外、转告邻居或上报有关单位等。例如,丰南县一家,主人曾经历过1970年云南通海7.7级地震,知道一点地震前动物异常现象,7月27日夜间屋里顶棚上老鼠多而乱串,感觉不对,叫醒家人随即跑到户外,没多久大地震发生,全家人幸免于难。有115起目睹者发现动物异常现象后,感到疑惑不解,在观望中或在追赶动物的过程中发生地震。但是约80%的动物异常现象未能引起目睹者的注意,震后才醒悟到与地震有关。例如,丰南县稻地村一妇女在大地震时受重伤,临终前诉说,7月27日晚上孩子见到院内老鼠乱跑,说可能有地震,要搬出屋外住,自己没有理睬,反而责怪孩子乱说,大地震时孩子不幸遇难。这充分表明,普及地震知识具有十分重要的意义,一念之差就可能会危及到生命。 1976年松潘7.2级地震,与汶川同属于龙门山地震带。但是松潘地震前,动物异常等宏观前兆现象,在空间展布上,沿龙门山断裂带“三起三落”,逐步向震中迁移。宏观异常的三次高潮期分别为6月5日至7月3日主要在该断裂带南端的大邑、天全和宝兴一带,7月4日至28日主要在该断裂带中部的灌县、绵竹一带,8月2日至8月14日北移至震中附近的北川、江油等地。这不仅为松潘地震的成功预报提供了一定的依据,并有利于提高地震区广大群众抗震防震的警觉性。下列表述中,不符合文意的一项是( )
A.我们所说的地震前动物异常行为事件与地震有关,是指相当数量异常事件的统计概念,也即从大量的“偶然事件”中总结出的“一般规律”,并非指某一起异常事件。
B.地震的短临前兆现象,指的是动物异常行为事件在前兆时间里主要或集中出现在地震前一天之内,也有短至几分钟的,长至数天或十几天的。
C.1976年7月28日唐山大地震前一些动物出现的异常行为现象完全与地震有关,不是巧合,不需要进一步观察研究。
D.发现动物异常现象后,不是积极采取一定的防震措施,而是感到疑惑不解,在观望或在追赶动物的过程中消极等待地震发生,是由于缺乏动物震前预兆知识造成的。
