Ⅰ.阅读理解
It doesn't take decades of life experience to have a great idea, as many of these young inventors have proved.
The Electronic Television
The electronic television was first designed by a 14yearold kid in 1920.Philo Taylor Farnsworth shared his concept of an image transmitting (影像传送) device, an early design of the electronic television, with his science teacher, drawing diagrams on several blackboards in class.
By the age of 21 Farnsworth had a working model which served as a basis to all later development and versions of electronic televisions. After discovering a collection of technology magazines in the attic (阁楼) of his family's new home, he developed a passion and interest in electronics, which led him to explore inventions in the field of, specifically, the image transmission.
In 1927, a few years out of high school, Farnsworth was the first inventor to transmit a television image of a dollar sign, composed of 60 horizontal lines.
Braille Language
Louis Braille suffered a serious eye injury when he was just 3 years old.Not only did the accident cause him blindness on that side, but the infection spread and blinded the other eye as well.After more than a decade of struggling with the slow system of tracing his finger over raised letters, Braille was 12 when he learned of a method of silent communication originally created for the French military.He simplified it, and in 1824 the Braille language was born.
Popsicles (冰棍)
A lot of kids are easily distracted (分散注意力)—and thanks to the short attention span of 11yearold Frank Epperson, we now have popsicles.In 1905, Epperson, a San Francisco native, was stirring powdered drink mix into a cup of water when something else caught his attention.The mixture was forgotten outside the door, and when Epperson rediscovered the drink in the morning, it was a deliciously portable frozen popsicle.After years of making the frozen treats for friends, and eventually his own children, Epperson filed for a patent in 1924.
[语篇解读] 本文是一篇应用文。文章主要介绍了三个由年轻男孩发明的东西。
1．Who contributed his intelligence to the invention of TV?
A．Philo Taylor Farnsworth.
B．Farnsworth's science teacher.
C．Louis Braille.
D．Epperson.
解析：细节理解题。根据The Electronic Television部分的“The electronic television was first designed by a 14yearold kid in 1920.Philo Taylor Farnsworth shared his concept of an image transmitting device, an early design of the electronic television (1920年，一个14岁的孩子首次设计了电子电视。Philo Taylor Farnsworth分享了他关于影像传送设备的概念，这是一个早期的电视设计)”和“In 1927，a few years out of high school，Farnsworth was the first inventor to transmit a television image of a dollar sign, composed of 60 horizontal lines.(1927年，高中毕业没几年，Farnsworth是第一个把美元符号传输到电视上的发明家)”可知，Philo Taylor Farnsworth致力于电视的发明。故选A项。
答案：A
2．Which invention was accidentally made because of poor concentration?
A．The Electronic Television.
B．The Braille Language.
C．Dollar Sign.
D．Popsicles.
解析：细节理解题。根据Popsicles部分的“A lot of kids are easily distracted—and thanks to the short attention span of 11yearold Frank Epperson，we now have popsicles.(很多孩子都容易分散注意力——由于11岁的Frank Epperson缺乏注意力，我们现在有了冰棍)”可知，冰棍是因为一个孩子缺乏注意力而产生的。故选D项。
答案：D
3．What do the three inventions have in common?
A．They were all designed for the sake of kids.
B．They were all made by young boys.
C．They were all made in the 20th century.
D．They were all created within a few years.
解析：细节理解题。根据The Electronic Television部分的“The electronic television was first designed by a 14yearold kid in 1920.(1920年，一个14岁的孩子首次设计了电子电视)”，Braille Language部分的“Braille was 12 when he learned of a method of silent communication originally created for the French military.He simplified it, and in 1824 the Braille language was born(直到12岁，他才学会了一种最初为法国军队发明的无声交流方法。他简化了它，1824年，布莱叶盲文诞生了)”和Popsicles部分的“A lot of kids are easily distracted—and thanks to the short attention span of 11yearold Frank Epperson，we now have popsicles.(很多孩子都容易分散注意力——由于11岁的Frank Epperson缺乏注意力，我们现在有了冰棍)”可知，这三项发明的共同之处是它们都是由年轻男孩发明的。故选B项。
答案：B
