11. We know the famous inventors—the Thomas Edison and the Alexander Graham Bells—but what about the less famous ones What about the people who invented the traffic light and the windshield wiper (雨刮器) Shouldn't we know who they are
Joan McLean thinks so. In fact, McLean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she's developed a course on the topic. In addition to learning "who" invented "what", however, McLean also likes her students to learn the answers to the "why" and "how" questions. According to McLean, "When students learn the answers to these questions, they are better prepared to recognise opportunities for inventing and more motivated to give inventing a try."
Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement. "If I had not heard the story of the windshield wiper's invention," said Tommy Lee a senior physics major, "I never would have dreamed of turning my bad experience during a rainstorm into something so constructive." Lee is currently negotiating to sell his patent to an umbrella producer.
So, just what is the story behind the windshield wiper Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn't be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever(操作杆) on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.
Today we benefit from countless inventions and innovations. It's hard to imagine driving without Garrett A. Morgan's traffic light. It's equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses
1.By mentioning "traffic light" and "windshield wiper", the author indicates that countless inventions are _________.
A.beneficial, because their inventors are famous
B.beneficial, though their inventors are less famous
C.not useful, because their inventors are less famous
D.not useful, though their inventors are famous
2.Professor Joan McLean's course aims to ________.
A.add colour and variety to students' campus life
B.inform students of the windshield wiper's invention
C.carry out the requirements by Mountain University
D.prepare students to try their own inventions
3.Tommy Lee's invention of the unbreakable umbrella was ________.
A.not eventually accepted by the umbrella producer
B.inspired by the story behind the windshield wiper
C.due to his dream of being caught in a rainstorm
D.not related to Professor Joan McLean's lectures
答案以及解析

解析：① 这是一个简单句,of invention作定语。
② 这是一个复合句,when引导定语从句,修饰golden ages。
11.答案：1-3.BDB
解析：1.解析:根据第一段内容并结合下文可推断,作者提到交通信号灯、雨刮器等发明是想说无数的发明对人类十分有益,虽然它们的发明者没有太大的名气。
2.解析:根据第二段最后一句可知,Joan Mclean教授开设这门课程的目的就是让学生有足够的准备去尝试自己发明东西。
3.解析:根据第三段的内容可知, Tommy Lee发明“不会折断的雨伞”就是受到了雨刮器背后的故事的激励。
