Pathways to Research:Problem-solving
1.Pittsburgh's many hills aren't kind to bikers.Anyone hoping to pedal to work there has to contend with steep streets like Canton Avenue,which famously climbs at a nearly 40-degree angle.As a result,some residents avoid biking altogether.
2.But University of Pittsburgh graduate Micah Toll,23,and a few friends recently launched an invention that they hope will, increase the city's pedal power:An electric bike called a Pulse PEVO.AM super-strong battery powers the bicycle.Able to hit nearly 20 miles per hour without pedaling,it zips up the city' s most daunting（令人却步的）hills.Toll hopes it will persuade people in Pittsburgh and elsewhere to get out of their cars and onto bikes.
3.If it sounds like Toll has a knack（窍门）for fixing problems,that's because he does.In high school,he designed a new type of construction beam.It weighs no more than a feather pillow but can be used to build sturdy（坚固的）homes for refugees fleeing war or natural disaster.For his work , Toll was invited to attend the Intel International Science and Engineering Fair(ISEF）-twice,in 2006 and 2007.The annual competition for young researchers is a program of Society for Science&the Public(that's the parent organization of Science News for Kids).Toll says that when it comes to science,he keeps it simple:"You see a problem and say,‘How could I solve that?’",
4.He's not the only one to take that approach.Many young researchers get their start by trying to solve a problem or fulfill a need in their own communities.When students dedicate themselves to finding a solution that may benefit their community , " a passion is ignited,（点燃）,"says Wendy Hawkins , executive director of the Intel Foundation,which sponsors Intel ISEF."Finding that passion and fostering it can be the key to many students'future success."she says.
选项 Many young researchers are finding solutions to problems that may______.
A:a nearly 40-degree angle
B:get on bikes
C:a feather pillow
D:fix more problems
E:a super-strong battery
F:benefit their community
答案F
解析第一段表明，匹兹堡多山，而且街道的坡度很陡，因此许多人不骑自行车出行。由此可知，第一段主要讲的是人们在匹兹堡不骑自行车的原因。
第二段主要表明，Toll发明的超能电池能够为自行车提供更强的动力，可鼓励匹兹堡的人骑自行车出行。由此可知，本段主要讲的是一项能够增强自行车动力的发明。
第三段的主题句是第一句，紧接着列举Toll在高中设计新型建筑横梁的例子，主要表明 Toll有解决问题的窍门和热情。
第四段表明，只要能使他们的集体受益，年轻的研究者们对解决问题非常有激情。由第三句中的passion一词也可知C项正确。
根据第二段第二句可知，为Pulse PEVO提供动力的是一种超强电池。
由第二段最后一句可知，Toll希望Pulse PEVO能鼓励匹兹堡和其他地方的人骑自行车。encourage是persuade的同义转换。
由第三段第二、三句可知，Toll设计的建筑横梁与羽毛枕头差不多重。
由第四段第三句“…that may benefit their community…”可知，本题应该选择F项。
