17.We know the famous ones--the Thomas Edisons and the Alexander Graham Bells--but what about the less famous inventors?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 recognize 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 rain storm 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 1902after 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 (操作桿) 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?
4.By mentioning"traffic light"and"windshield wiper",the author indicates that countless inventions areB.
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
5.Professor Joan McLean's course aims toD.
A.a(chǎn)dd color 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 invention
6.Tommy Lee's invention of the unbreakable umbrella wasB.
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
7.Which of the following can best serve as the title of this passage?C
A.How to Help Students to Sell Their Inventions to Producers?
B.How to Design a Built-in Device for Cleaning the Window?
C.Shouldn't We Know Who Invented the Windshield Wiper?
D.Shouldn't We Develop Invention Courses in Universities?
分析 一位物理學教授通過自己獨特的課程不但讓學生們了解了一些"小"發(fā)明家,同時也激發(fā)了學生們搞發(fā)明的潛能.
解答 4-7 BDBC
4題答案:B考查細節(jié)推理,根據(jù)第一段中的"…but what about the less famous inventors?"(但是那些不是很著名的發(fā)明家呢?)和文章末段首句"Today we benefit from countless…"(今天我們受益于無數(shù)的…)可推知,作者認為相對愛迪生和貝爾來說,雖然發(fā)明家知名度低,但這些發(fā)明是有益的;故本題答案為B選項.
5題答案:D考查細節(jié)推理,根據(jù)第二段末句"…they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try."(他們能夠更好地準備認識發(fā)明的機會而且更有動力去嘗試發(fā)明). 可知,讓學生做好準備去嘗試自己的發(fā)明是課程的宗旨;故本題答案為D選項.
6題答案:B考查細節(jié)推理,根據(jù)第三段中的虛擬語氣句"If I had not heard the story of the windshield wiper's invention""I never would have dreamed of turning my bad experience during a rainstorm into something so constructive."(如果我沒有聽說過刮雨器的發(fā)明,我永遠都不可能想著要把暴風雨中糟糕的經(jīng)歷變?yōu)槿绱擞薪ㄔO性的東西).可知,雨刷器發(fā)明的故事正是他靈感的源泉;可知本題答案為B選項.
7題答案:C考查主旨大意,文章圍繞"雨刷器發(fā)明的故事"展開,結(jié)合第一段末句"Shouldn't we know who they are?"(難道我們不應該知道他們是誰嗎?)可知,本題答案為C選項.
點評 本文是一篇科教類閱讀,題目涉及多道細節(jié)理解題,做題時結(jié)合原文和題目有針對 性找出相關語句進行仔細分析,結(jié)合選項選出正確答案.推理判斷也是要在抓住關鍵句子的基礎上合理的分析才能得出正確的答案.
