Americans are used to ordering things ranging from French fries to popcorn in small, medium or supersize. Now those same decision-making skills may become rueful in the bathroom, thanks to an innovative plumbing technology: dual-flush toilets. The new invention is the industry’s latest attempt to help reduce water usage, a movement that hasn’t always gone smoothly. The last big toilet makeover came more than a decade ago, when the U.S. government decreed that new toilets should use just 1.6 gallons of water per flush, down from the 3.5-gallon standard. But consumers complained that it often took two or more flushes to clear the bowl; so many people preferred the old toilets that some plumbers imported them illegally from Canada.

问答题Directions: In this part, there is 1 passage followed with 5 statements. Read the passage and decide which of the statements at the end of the passage are true and which are false. Remember to write the answers on the Answer Sheet. Questions 1 to 5 are based on the following passage. Enya was born in 1961, 17 May, and spent her childhood in Gweedore. There are nine brothers and sisters in the family, four other girls and four boys. All the family have won many competitions and are famous in national traditional music circles. Whilst at school, Enya studied the piano and classical music. Three of her brothers and sisters formed, together with their uncles, a folk music group (at first with a certain American feel and then more purely Irish, though influenced by jazz and by others such as Pentangle). The group was named Clannad, a contraction of “the family from Gweedore” in Irish. In 1980, at the suggestion of their manager, Fachtna O’Kelly, Enya became a member of the group. She performed with Clannad on many occasions, until, in February 1982, on completing a European tour, she left the group, no one really knowing why. It was also Fachtna O’Kelly who suggested to Enya after she left Clannad, that she devoted herself to composing for films. And so, in 1984, she approached her first important task. Roma Ryan had sent a cassette of Enya to film producer David Puttnam. Puttnam asked her to compose dreamy and romantic music with a sixties feel for the feature film The Frog Prince. Having a studio at her disposal, Enya worked almost always at home with the Roland Juno 60 synthesizer or the Kurzweil sampler, and then added piano and voice. Nicky Ryan recorded everything and helped to put the compositions into their final form. Enya’s first record subsequently climbed to number one in the Irish charts, which started the commercial rise of Enya. She collaborated with the singer Sinéad O’Connor reciting a short text on “Never Get Old” from her album The Lion And The Cobra. She signed with an important multinational, and had a resounding success with her second album Watermark, which has passed 10 million sales worldwide, and has gone platinum in 14 different countries, helped by the single “Orinoco Flow”, a No 1 hit in Britain. Then she repeated her world success with Shepherd Moons, which spent an amazing 199 weeks on the Billboard charts in the USA and has sold over 11 million copies. Statements: 1．All the family are well known in national traditional music circles. 2．Three of Enya’s brothers and sisters with their uncles formed a purely American folk music group at first. 3．It was Fachtna O’Kelly who suggested Enya join Clannad and then quit it. 4．Enya’s second album Watermark has been translated into different versions in 14 counties. 5．The single “Orinoco Flow” from Watermarkspent an amazing 199 weeks on the Billboard charts.

问答题Directions:In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in a maximum of 10 words. Remember to write the answers on the Answer Sheet. High Dropout Rate in US Many young people in the United States never finish high school. Exactly how many dropouts is another issue. Recent studies of dropout rates have had conflicting results. For one thing, schools define and measure their dropout rates differently. Some researchers say about fifteen to twenty parents of public school students do not complete their education. But many other experts and policymakers believe that for the past twenty years, the dropout rate has been around thirty percent. For Latino and black students, the numbers are even higher. Researchers say almost half of them leave school. At the same time, almost half the states let students leave school before the age of eighteen without informing their parents. Finding a good job without a high school education is more and more difficult. A Northeastern University study in 2002 found that almost half of all dropouts aged sixteen to twenty-four did not have a job. The lack of high school education can also lead to other problems. An estimated two-thirds of prisoners in the United States dropped out of high school. Recent studies have shown that the majority of students who drop out do not do it because they are failing. Many are bored with their classes or feel disconnected from their school and teachers. Some students feel that educators place low expectations on them. Teen pregnancies also add to the dropout problem. During the past twenty years, there have been efforts to increase graduation rate through education reforms. Some communities are working on dropout prevention programs. These include alternative high schools to meet special needs. Some programs, for example, provide free transportation and childcare to help young mothers and fathers finish school. Yet special programs can cost a lot, and many school systems have limited budgets. Federal spending on second-chance programs to help students finish school has decreased from the 1970s. This was shown in a report last year from the Educational Testing Service. Experts suggest early warning systems to help identify young schoolchildren at risk of dropping out of high school. They say schools also need to get parents more involved, especially if their children are missing school often. Questions: 1．What is the researchers’ estimated percentage of school dropouts among Latino and black students? 2．What efforts have been made to increase graduation rates? 3．What has been done to help young parents complete their education? 4．Who made a report about the decrease，of Federal spending on second-chance programs to help students finish school? 5．What do experts suggest setting up to help prevent students from dropping out of school?

问答题Fuel Cells: 21st Century Electricity The 21st century’s leading energy source may very well depend on the development of a technology that was first discovered in 1839. Indeed, many experts believe that the future of electricity generation will not come from further refinement of solar, wind, coal or nuclear energy, but from fuel cells. Among the various types of fuel cells, the ceramic or solid oxide fuel cell promises to achieve the greatest efficiency of conversion of fossil fuels such as gas and coal to electricity while producing only very low levels of pollutants. To this end, a consortium comprising five leading organizations has established Ceramic Fuels Ltd, initially to expand fuel cell research and development and secondly, to bring the technology to commercial application. Ceramic fuel cells are electrochemical devices that directly convert fuels such as gasified coal or natural gas into electricity without the limitation of the Carnot cycle (an ideal thermodynamic cycle in which heat is taken onto a working fluid at a constant upper temperature and rejected at a constant lower temperature). In many respects, fuel cells work like batteries. As long as they are constantly supplied with fuel and oxidant, fuel cells can continuously produce power, removing the need for recharging. Fuel cells offer several advantages over traditional thermal power plants. The major difference between these two power generators is that the chemical energy of the fuel cell is converted directly to electrical power without intermediate conversion first to heat. The efficiency of a coal-fired thermal plant is typically in the range of 30%-35%. In a combined cycle gas turbine system running on natural gas, the maximum efficiency is in the range 45%-50%. Many experts believe high temperature fuel cells could reach efficiencies of 80%-85%. Ceramic fuel cells thus offer a more efficient and less polluting alternative to current power generation technologies. By-products from fuel cells are high quality heat, carbon dioxide and steam. The temperature of the exhaust gases is well above 500℃, meaning that solid oxide fuel cells are very attractive for electricity and heat generation as, in addition to supplying electricity, the leftover amounts of heat created during the process could be used to produce heat for industries, provide hot water supplies or warm buildings. Fuel cell technology is not new. In fact, the principles of fuel cell operation were first reported by British scientist Sir William Grove in 1839. His prototype used dilute sulphuric acid and operated at room temperature. Ceramic fuel cells developed much later, with the first one operating at 1000°C in 1937. Ceramic fuel cells offer many advantages over other energy systems: ● they have the potential to produce electricity efficient from several fuel sources ● they can generate large amounts of electricity ● they are relatively quick to install Fuel cell research and development is extremely competitive worldwide, with the USA, Japan and some European countries leading the charge to commercialize this promising technology. For instance, a Dutch Belgian company has developed a fuel cell for a Volkswagen van and is also working on a larger unit to power a bus. Additionally, a German company is working on a fuel cell for the European space shuttle program and for submarines, while a Canadian company is evaluating a fuel cell to be used in small buses. Recent reports point to promising large international markets for ceramic fuel cells. Prospects for fuel cells in South East Asian markets appear good. Several countries, including Indonesia, Thailand and The Philippines are expected to demonstrate high rates of growth in demand for power an encouraging situation for those countries quick enough to develop and commercialize fuel cell technology. Energy is a vital component of a technology-based society and the growing need for electricity generation by the most efficient method will ensure a promising future for ceramic fuel cell technology. The Ceramic Fuel Cells Ltd initiative represents a major collaborative venture between public and private sectors. It is envisaged that this venture will go a long way towards achieving a greater efficiency of energy use worldwide. Do the following statements reflect the claims of the writer in the Reading Passage? YES if the statement reflects the claims of the writer NO if the statement contradicts the claims of the writer NOT GIVEN if it is impossible to say what the writer thinks about this Statements: 1．Sir William Grove was a physicist. 2．Future transport vehicles may be powered by fuel cells. 3．European companies were first in the race to develop fuel cell technology. 4．Some rapidly developing South East Asian countries will soon market fuel cells. 5．Cooperation between private companies and governments will encourage wider use of efficient energy sources.
