Shouldn't We KnowWho Invented the Windshield Wiper

We know the famousones一the Thomas Edison andthe Alexander Graham Bells一but what about the lessfamous inventors?What about the people who invented the traffic

light and thewindshield wiper（雨刷器）?Shouldn't we know who they are?

Joan Mclean thinksso.In fact,Mclean,a professor of physics at Mountain Universityin Range,feels so strongly about this matter that she's developed a course onthe topic.In

addition tolearning" who"invented"what",however,Mclean also likes herstudents to learn the answers to the"why"and"how"questions.According to Mclean,"whenstudents

learn the answers tothese questions,they are better prepared to recognize opportunities forinventing and more motivated to give inventing a try".

Her studentsagree.One young man with a patent for an unbreakable umbrella is walking proofof McLean's statement."If I had not heardof the story of the windshield wiper's

invention,"saidTommy Lee,a senior physics major,"I never would have dreamed of turning mybad experience during a rainstorm into something so constructive."Lee is

currentlynegotiating to sell his patent to an umbrella producer.

So,just what is thestory behind the windshield wiper? Well,Mary Anderson came up with the idea in1902 after a visit to New York City.The day was cold and stormy,but

Anderson still wanted to see the sights,so she jumpedaboard a streetcar. Noticing that the driver was struggling to see through thesnow covering the windshield,she found

herself wonderingwhy there couldn't be a built-in device for cleaning the window. Stillwondering about this when she returned home to Birmingham,Alabama,Anderson

started drafting outsolutions. One of her ideas,a lever（操作杆）on the inside of a vehicle that would control an arm on theoutside,became the first windshield wiper.

Today we benefitfrom countless inventions and innovations,It's hard to imagine driving withoutGarrett A.Morgan's traffic light. It'5equally impossible to picture a world

without Katherine J.Blodgett's innovation that makes glass invisible.Can you picture life withoutclear windows and eyeglasses?Which of thefollowing is NOT true?

A.The firstwindshield wiper was invented in New York City.

B.Mary made a visitto New York City.

C.When Andersonreturned home,she still remembered her inspirations on the way.

D.Mary Andersoninvented a lever on the inside of a vehicle that became the first windshieldwiper.
