共用题干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
Paragraph 1______A:Intel International Science and Engineering FairB:The Enthusiasm for Solving ProblemsC:The Young Researchers'PassionD:An Invention Increasing Pedal PowerE:Why People Avoid Biking in Pittsburgh F:The Cause of National Disaster
答案
E
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。
