10、A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1How can the train operators possibly justify yet another increase to rail passenger fares? It has become a grimly reliable annual ritual: every January the cost of travelling by train rises, imposing a significant extra burden on
11、those who have no option but to use the rail network to get to work or otherwise. This years rise, an average of 2.7 percent, may be a fraction lower than last years, but it is still well above the official Consumer Price Index (CPI) measure of inflation.Successive governments have permitted such in
12、creases on the grounds that the cost of investing in and running the 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 Lincolnshire have to subsidise the daily commute of a stockbroker from Surrey? Equally,
13、 there is a sense that the travails of commuters in the South East, many of whom will face among the biggest rises, have received too much attention compared to those who must endure the relatively poor infrastructure of the Midlands and the North.However, over the past 12 months, those commuters ha
14、ve also experienced some of the worst rail strikes in years. It is all very well train operators trumpeting the improvements they are making to the network, but passengers should be able to expect a basic level of service for the substantial sums they are now paying to travel. The responsibility for
15、 the latest wave of strikes rests on the unions. However, there is a strong case that those who have 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 requirement so t
16、hat, even when strikes occur, services can continue to operate. This should form part of a wider package of measures to address the long-running problems on Britains railways. Yes, more investment is needed, but passengers will not be willing to pay more indefinitely if they must also endure cramped
17、, unreliable services, punctuated by regular chaos when timetables are changed, or planned maintenance is managed incompetently. The threat of nationalisation may have been seen off for now, but it will return with a vengeance if the justified anger of passengers is not addressed in short order.21.
18、The author holds that this years increase in rail passengers fares .A will ease train operations burden3- 3 -B has kept pace with inflationC is a big surprise to commutersD remains an unreasonable measure22. The stockbroker in paragraph 2 is used to stand for .A car driversB rail travellersC local i
19、nvestorsD ordinary tax payers23. It is indicated in paragraph 3 that train operators .A are offering compensations to commutersB are trying to repair relations with the unionsC have failed to provide an adequate sourceD have suffered huge losses owing to the strikes24. If unable to calm down passeng
20、ers, the railways may have to face .A the loss of investmentB the collapse of operationsC a reduction of revenueD a change of ownership25. Which of the following would be the best title for the text?A Who Are to Blame for the Strikes?B Constant Complaining Doesnt WorkC Can Nationalization Bring Hope
21、?D Ever-rising Fares Arent SustainableText 2Last year marked the third year in a row of when Indonesias bleak rate of deforestation has slowed in pace. One reason for the turnaround may be the countrys antipoverty program.In 2007, Indonesia started phasing in a program that gives money to its poores
22、t residents under certain conditions, such as requiring people to keep kids in school or get regular medical care. Called conditional cash transfers or CCTs, these social assistance programs are designed to reduce inequality and break the cycle of poverty. Theyre already used in dozens of countries
23、worldwide. In Indonesia, the program has provided enough food and medicine to substantially reduce severe growth problems among children.But CCT programs dont generally consider effects on the environment. In fact, poverty alleviation and environmental protection are often viewed as conflicting goal
24、s, says Paul Ferraro, an economist at Johns Hopkins University.Thats because economic growth can be correlated with environmental degradation, while protecting the environment is sometimes correlated with greater poverty. However, those correlations dont prove cause and effect. The only previous stu
25、dy analyzing causality, based on an area in Mexico that had instituted CCTs, supported the traditional view. There, as people got more money, some of them may have more cleared land for cattle to raise for meat, Ferraro says.Such programs do not have to negatively affect the environment, though. Fer
26、raro wanted to see if Indonesias poverty-alleviation program was affecting deforestation. Indonesia has the third- largest area of tropical forest in the world and one of the highest deforestation rates.Ferraro analyzed satellite data showing annual forest loss from 2008 to 2012including during Indo
27、nesias phase-in of the antipoverty programin 7,468 forested villages across 15 provinces and multiple islands. The duo separated the effects of the CCT program on forest loss from other factors, like weather and macroeconomic changes, which were also affecting forest loss. With that, “we see that th
28、e program is associated with a 30 percent reduction in deforestation,” Ferraro says.Thats likely because the rural poor are using the money as makeshift insurance policies against inclement weather, Ferraro says. Typically, if rains are delayed, people may clear land to plant more rice to supplement
29、 their harvests. With the CCTs, individuals instead can use the money to supplement their harvests.Whether this research translates elsewhere is anybodys guess. Ferraro suggests the results may transfer to other parts of Asia, due to commonalities such as the importance of growing rice and market ac
30、cess. And regardless of transferability, the study shows that whats good for people may also be good for the environment. Even if this program didnt reduce poverty. Ferraro says, “the value of the avoided deforestation just for carbon dioxide emissions alone is more than the program costs.”26. Accor
31、ding to the first two paragraphs, CCT programs aim to .A facilitate health care reformB help poor families get better offC improve local education systemsD lower deforestation rates27. The study based on an area in Mexico is cited to show that .A cattle rearing has been a major means of livelihood f
32、or the poorB CCT programs have helped preserve traditional lifestylesC antipoverty efforts require the participation of local farmersD economic growth tends to cause environmental degradation28. In his study about Indonesia, Ferraro intends to find out .A its acceptance level of CCTsB its annual rat
33、e of poverty alleviationC the relation of CCTs to its forest lossD the role of its forests in climate change29. According to Ferraro, the CCT program in Indonesia is most valuable in that .A it will benefit other Asian countriesB it will reduce regional inequalityC it can protect the environmentD it
34、 can boost grain production30. What is the text centered on?A The effects of a program.B The debates over a program.C The process of a study.D The transferability of a study.Text 3As a historian, whos always searching for the text or the image that makes us re-evaluate the past. Ive become preoccupi
35、ed with looking for photographs that show our Victorian ancestors smiling (what better way to shatter the image of 19th-century prudery?). Ive found quite a few, andsince I started posting them on Twitterthey have been causing quite a stir. People have been surprised to see evidence that Victorians
36、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 that separate 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 perce
37、ntage of the vast catalogue of photographic portraiture created between 1840 and 1900, the majority of which show sitters posing miserably and stiffly in front of painted backdrops, or staring absently into the middle distance. How do we explain this trend?During the 1840s and 1850s, in the early da
38、ys of photography, exposure times were notoriously long: the daguerreotype photographic method (producing an image on a silvered copper plate) could take several minutes to complete, resulting in blurred images as sitters shifted position or adjusted their limbs. The thought of holding a fixed grin
39、as the camera performed its magical duties was too much to contemplate, and so a non-committal blank stare became the norm.17- 17 -But exposure times were much quicker by the 1880s, and the introduction of the Box Brownie and other portable cameras meant that, though slow by todays digital standards
40、, the exposure was almost instantaneous. Spontaneous smiles were relatively easy to capture by the 1890s, so we must look elsewhere for an explanation of why Victorians still hesitated to smile.One explanation might be the loss of dignity displayed through a cheesy grin. “Nature gave us lips to conc
41、eal our teeth,” ran one popular Victorian maxim, alluding to the fact that before the birth of proper dentistry, mouths were often in a shocking state of hygiene. A flashing set of healthy and clean, regular “pearly whites” was a rare sight in Victorian society, the preserve of the super-rich (and e
42、ven then, dental hygiene was not guaranteed).A toothy grin (especially when there were gaps or blackened gnashers) lacked class: drunks, tramps, prostitutes and buffoonish music hall performers might gurn and grin with a smile as wide as Lewis Carrolls gum-exposing Cheshire Cat, but it was not a bec
43、oming look for properly bred persons. Even Mark Twain, a man who enjoyed a hearty laugh, said that when it came to photographic portraits there could be “nothing more damning than a silly, foolish smile fixed forever”.31. According to Paragraph 1, the authors posts on Twitter .A illustrated the deve
44、lopment of Victorian photographyB highlighted social medias role in Victorian studiesC re-evaluated the Victorians notion of public imageD changed peoples impression of the Victorians32. What does the author say about the Victorian portraits he has collected?A They are rare among photographs of that
45、 age.B They show effects of different exposure times.C They mirror 19th-century social conventions.D They are in popular use among historians.33. What might have kept the Victorians from smiling for pictures in the 1890s?A Their inherent social sensitiveness.B Their tension before the camera.C Their
46、 distrust of new inventions.D Their unhealthy dental condition.34. Mark Twain is quoted to show that the disapproval of smiles in pictures was .A a deep-root beliefB a misguided attitudeC a controversial viewD a thought-provoking idea35. Which of the following questions does the text answer?A Why did m
