10、er the questions below each text by choosing A,B,C or D.Markyour answers on the ANSWER SHEET(40 points)Text 1How can Britains train operators possibly justify yet another increase to rail passenger fares?It has become agrimly reliable annual ritual:every January the cost of travelling by train rises
11、,imposing a significant extra burdenon those who have no option but to use the rail network to get to work or otherwise.This years rise an average of2.7 percent,maybe a faction lower than last years,but it is still well above the official Consumer Price Ind-er(CPI)measure of inflation.Successive gov
12、ernments have permitted such increases on the grounds that the cost of investing in and runningthe rail network.Should be borne by those who use it,rather than the general taxpayer.Why,the argument goes,should a car-driving pensioner from Lincoln-shire have to subscribe the daily commute of a stockb
13、roker fromsurvey?Equally,there is a sense that the travails of commuters in the south East,many of whom will face amongthe biggest rises,have received too much attention compared to those who must endure the relativity poorinfrastructure of the Mid lands and the North.However,over the past 12 months
14、,those commuters have also experienced some of the worst rail strikes inyears.It is all very well train operators trumpeting the improvements they are making to the network,butpassengers should be able to expect a basic level of service for the substantial sums they are now paying to travel.The resp
15、onsibility for the test wave of strikes rests on the wines.However,there is a strong case that those whohave been worst affected by industrial action should receive compensation for the disruption they have suffered.The Government has pledged to change the law to introduce a minimum service requirem
16、ent,so that evenwhen strikes occur services can continue to operate.This should from part of a wider package of measures toaddress the long-running problems on Britains railways.Yes,more investment is needed,but passengers will notbe willing to pay more indefinitely if they must also endure cramped,
17、unreliable services interrupted by regularchaos when time tables are changed,or planned maintenance is managed incompetently.They threat ofnationalization may have been seen off for now,but it will return with a vengeance if the justified anger ofpassengers is not addressed in short order.21.The aut

21、 Fares Arent SustainableText 2Last year marked the third year in a row that Indonesias bleak rate deforestation has slowed in pace.Onereason for the turnaround may be the country*s antipoverty program.In 2007,Indonesia started phasing in a program that gives money to its poorest residents under cert
22、ainconditions,such as requiring people to keep kids in school or get regular medical care.Called conditional cashtransfers or CCTs,these social assistance programs are designed to reduce inequality and break the cycle of poverty.They are already used in dozens of countries worldwide.In Indonesia,the
23、 programme has provided enough foodand medicine to substantially reduce severe growth problems among children.But the CCT programs dont generally consider effects on the environment.In fact,poverty alleviation andenvironmental protection are often viewed as conflicting goals,says Paul Ferraro,an eco
24、nomist at Johnns HopkinsUniversity.Thats because economic growth can be correlated with environmental degradation,while protecting theenvironment is sometimes correlated with greater poverty.However,those correlations don*t prove cause and effect,The only previous study analyzing causality,based on
25、an area in Mexico that had instituted CCTs,supported thetraditional view.There,as people got more money,some of them may have more cleared land for cattle to raise formeat,Ferraro says.Such programs do not have to negatively affect the environment,though.Ferraro wanted to see if Indonesiaspoverty-al
26、leviation program was affecting deforestation.Indonesia has the third-largest area of tropical forest in theworld and one of the highest deforestation rates.Ferraro analyzed satellite data showing annual forest loss from 2008 to 2012 including during Indonesiasphase in of the antipoverty program in
27、7,468 forested villages across 15 provinces.t4We see that the program isassociated with a 30 percent reduction in deforestation,Farrow says.Thats likely because the rural poor are using the money as makeshift insurance policies against inclementweather,Ferraro says.Typically,if rains are delayed,peo
28、ple may clear land to plant more rice to supplement theirharvest.With the CCTs,individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybodys guess.Farrow suggests the results may transfer toother parts of Asia,due to commonalities such as t
29、he importance of growing rice and market access.And regardlessof transferability,the study shows that whats good for people may also be good for the environment.Even if thisprogram didnt reduce poverty.Ferraro says,“the value of the avoided deforestation just for carbon dioxideemissions alone is mor

35、torians had fun and could,and did,laugh.They are noting that the Victorians suddenly seem to become more human as the hundred-or-so years thatseparate us fade away through our common experience of laughter.Of course,I need to concede that my collection of Smiling Victorians,makes up only a tiny perc
36、entage of thevast catalogue of photographic portraiture created between 1840 and 1900,the majority of which show sittersposing miserably and stiffly in front of painted backdrops,or staring absently into the middle distance.How do weexplain this trend?During the 1840s and 1850s,in the early days of
37、photography,exposure times were notoriously long:thedaguerreotype photographic method(producing an image on a silvered copper plate)could take several minutes tocomplete,resulting in blurred images as sitters shifted position or adjusted their limbs.The thought of holding afixed grin as the camera p
38、erformed its magical duties was too much to contemplate,and so a non-committal blankstare became the norm.But exposure times were much quicker by the 1 880s,and the introduction of the Box Brownie and otherportable cameras meant that,though slow by todays digital standards,the exposure was almost in
39、stantaneous.Spontaneous smiles were relatively easy to capture by the 1890s,so we must look elsewhere for an explanation ofwhy Victorians still hesitated to smile.One explanation might be the loss of dignity displayed through a cheesy grin.Nature gave us lips to concealour teeth.ran one popular Vict

47、power and incentive to favor affiliated websites overtheir rivals.Thats why there has been such a strong demand for rules that would prevent broadband providers frompicking winners and losers online,preserving the freedom and innovation from what have been the lifeblood of theInternet.Yet that deman
