题目内容
5.At this year's Technology Forum,speakers include world-famous people,such as Steve Wozniak,co-founder of Apple Computer,and lesser-known individuals with great ideas to change the world.One of the latter is Jonny Cohen,a high school senior,green businessman and creator of GreenShields.Since Cohen was a child,he has been innovating and inventing.When he was 12 and took science classes at Northwestern University,he saw a school bus and had an idea:what if the shape of school bus was improved to make it more fuel efficient?This would greatly reduce the amount of pollution it produced.He set about making a wind tunnel in his parents'garage and placed small metal plates or shields on toy school buses to test them.The result:his shields redirected the airflow over and around the bus,decreased wing drag,and produced better fuel economy and less pollution.
Cohen went through various experiments to improve his GreenShields invention.With the help of MIT and Cook-Illinois Bus Company,which donated a full-sized bus for Cohen's experiments,he now has a shield model that is inexpensive and easy to attach,enabling widespread adoption.
How much of an impact can these shields have on climate change?Fuel consumption for the average US school bus is seven miles per gallon.GreenShields increases fuel efficiency by 10-20%,saving about 600 per bus per year,and costs only 30 to attach.Cohen and his partners are now trying to persuade the government to put GreenShields on all school buses.
With almost half-a-million school buses in America using nearly 2.5 billion of fuel per year,a consumption reduction of 10-20% would make a big difference in pollution.Not to mention the roughly 285 million in annual savings on fuel.
28.What can we learn about Jonny Cohen from the text?D
A.He has produced GreenShields independently.
B.He has been employed to improve school buses.
C.He is a world-famous businessman and inventor.
D.He has a talent for finding and solving problems.
29.How does GreenShields make a bus more fuel efficient?A
A.By reducing the amount of wind drag.
B.By improving the quality of fuel used.
C.By providing a wind tunnel for the bus.
D.By changing the shape of the bus engine.
30.Where did Cohen begin testing his shields?B
A.At Northwestern University.
B.In his parents'garage.
C.At a local bus company.
D.In an MIT lab.
31.What's the intended benefit of Cohen's invention?D
A.To provide school buses with cheaper fuel.
B.To reduce the cost of producing school buses.
C.To increase the profits of the school bus industry.
D.To make school buses more environmentally-friendly.
