Passage Two Questions 27 to 31 are based on the following passage.
Sixteen-year-old Karlos Dearman’s future is looking much brighter than he might previously have imagined. “I’ve always been into bikes, but never thought I’d end up working with them,” he says. “This scheme has changed my life.”
Karlos is learning to refurbish (翻新) old bicycles in the workshop of ReCycle Bikes, a local community charity in Sheffield, which has a contract with the city council to provide training opportunities for young people aged 14 to 16, particularly those struggling in mainstream education or excluded from school.
“It’s about engaging youngsters with education and youth training by teaching them work and life skills,” explains Des Pearce, workshop training manager. “These young people have so much potential, but often don’t realize it.”
Established in 2001, ReCycle Bikes repairs bicycles donated by the public, which, once restored, are sold for ￡20. Abandoned bikes supplied by the council ensure a steady flow of bikes, but a recently formed partnership with Sheffield University should improve further the prospects of the young mechanics.
“The student population presents a large and ready market,” says Pearce. “So we approached the university last year and offered to host bike sales on the campus. They thought it was a great idea, and agreed to supplement our council funding. This means we can train youngsters to repair extra 500 bikes over three years, and fund Karlos’s apprenticeship.”
Having set up ReCycle Bikes on his own, Pearce now has the staff and resources to track the career development of those who have passed through his workshop.
“At the moment we depend on anecdotal evidence from the schools,” he says. “But we are planning exit interviews with the young people to ascertain what they plan to do, and these will allow us to check on their progress.”
That most of the teenagers enjoy the work is, according to Pearce, easily explained. “Most kids have ridden a bike and know how to oil a chain or mend a puncture. As low-cost transport, cycling gives the young and old a sense of freedom and independence, and the impact on their well-being is immense. Add to that a growing concern for the environment, and it’s no surprise that bike sales are on the increase.”
第27题：What do we know about ReCycle Bikes？
A) It is a popular brand of bikes which are sold in Sheffield.
B) It is a local community charity that provides training opportunities for young people.
C) It is a contract signed between a local community charity and the city council.
D) It is a training program offered by the city council to those excluded from school.

根据以下材料，回答题
Better Solar Energy Systems: More Heat， More Light
Solar photovoltaic thermal energy systems， or PVTs， generate both heat and electricity， but__________ （51） now they haven"t been very good at the heat-generating part compared to a stand-alone solar thermal collector. That"s because they operate at low temperatures to cool crystalline silicon solar cells，__________ （52） lets the silicon generate more electricity but isn"t a very efficient way to gather heat.
That"s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower__________（53）. And it"s also a space problem: photovoltaic cells can__________ （54） up all the space on the roof， leaving little room for thermal applications.
In a pair of studies， Joshua Pearce， an associate professor of materials science and engineering，has devised a__________ （55） in the form. of a better PVT made with a different kind of silicon.
His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen"s University， Canada.
Most solar panels are made with crystalline silicon， but you can also make solar cells out of amorphous silicon， commonly known__________ （56） thin-film silicon. They don"t create as much electricity， but they are lighter， flexible， and cheaper. And， because they__________ （57） much less silicon， they have a greener footprint. __________ （58）， thin-film silicon solar cells are vulnerable to some bad-news physics in the form. of the Staebler-Wronski effect.
"That means that their efficiency drops when you __________（59） them to light——pretty much the worst possible effect for a solar cell，" Pearce explains， which is one of the__________ （60） thin-film solar panels make up only a small fraction of the market.
However， Pearce and his team found a __________（61） to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new __________（62） of PVT. You don"t have to cool down thin-film silicon to make it work. In fact， Pearce"s group discovered that by heating it to solar-thermal operating temperatures， near the boiling__________ （63） of water， they could make thicker cells that largely __________（64） the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector， they also found that by baking the cell once a day， they__________ （65） the solar cell"s electrical efficiency by over 10 percent.
