It is small and open, with one roof over the stage where singers perform and another roof over part of the audience. This opera house in the mountain is one of the best in the country, which may seem surprising because performances are only given during the seven weeks in summer, and because Santa Fe is a very small city.One reason why the Santa Fe Opera is so good is that it attracts many excellent young singers. They all hope to sing in famous opera houses like Metropolitan Opera House in New York City someday, and they work hard to become well known during the summer. The musicians and directors are experts who come from the best orchestras(管弦乐队) and operas in the country during their vacations. They enjoy working there because they like to live in Santa Fe, which is near both the mountains and the desert. It is very beautiful there in summer.The state government of New Mexico advertises the Santa Fe Opera in the newspapers all over the country, and a great many tourists come to New Mexico because of the opera. Still, most of the audience does come from Santa Fe and other nearby cities, and all the seats in the theatre are sold for every show.There is only one thing that some people do not like about the Santa Fe Opera, and that is the cold weather. Because the theatre is open, performances cannot start before it gets dark at nine oclock in the evening, and then the mountain air becomes very cool. Sometimes people complain about the cold air, but because the operas are good, these people come back again wearing warm coats.1This passage mainly introduces _.Aa mountain cityByoung musiciansCan opera houseDthe tourism in Santa Fe2Yong singers come to perform in Santa Fe Opera because _.Athe music quality is highBthey enjoy the climate thereCthey want to be famousDthey like the scenery there3It seems surprising that Santa Fe becomes famous because _.Ait is only a very small placeBit is between the mountains and the desertCall the seats are sold for every showDmusicians there are from the best orchestras4From the passage, we can learn that _.Athe opera house is open without any roofsBmusicians always spend vacations in Santa FeCthe government advertises to attract more musiciansDperformances are held in Santa Fe Opera only after it is dark(二)All around the world, shoppers flock to WalMart to buy everything.In Texas, they come for another reason: to see the wind turbine(涡轮机), which supplies 5% of the stores electricity.It along with other facilities, such as exterior walls coated with heatreflective paint, makes this WalMart a green giant.The laws of economics suggest that WalMart, with 5, 200 stores worldwide, influences everything including the prices of all kinds of goods.It throws its weight behind environmental responsibility, and the impact could be amazing.“One little change in product packaging could save 1, 500 trees，” says WalMarts former CEO Lee Scott.“If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day they have made a huge difference.”Scott wants WalMart to do its part too.He has promised to cut the existing greenhouse gas emissions(排放物) over the next few years and promised to construct new stores that are more efficient.He wants WalMarts fleet(车队) of more than 7, 000 trucks to get twice as many miles per gallon by 2015.Factories that show WalMart theyre cutting air pollution will get preferential treatment in the supply chain.WalMart says its working with consumerproduct manufacturers to reduce their packaging and will reward them if they do so.Some people may doubt it is a bid to attract attention from WalMarts controversial labour and health insurance practices.But its not just window dressing, because WalMart sees profits in going green.Scott says，“This_is_a_business_philosophy,_not_a_social_philosophy.We dont go where we dont think theres great interest in change.”Like Bill Gates, who started his charitable foundation, Scott happens to be promoting WalMarts image at a time when his companys reputation is declining.He acknowledges that he launched the plan partly to shield(保护) WalMart from bad press about its contribution to global warming.“By doing what were doing today, we avoid the headline risks that are going to come for people who did not do anything，” he says.“At some point businesses will be held responsible for the action they take.”Meanwhile, should WalMart succeed in shrinking its environmental footprint and lowering prices for green products, both the planet and the company would profit.5We can infer from the passage that _.ALee Scott is WalMarts present CEOBthere are 5, 200 stores in the worldCWalMart has a great influence o
