Anderson worked in a small college．One afternoon, he was told to go to the station to meet a history professor named J．Maurice, who would be giving lectures in his college．Anderson had never met a professor coming from a university so far away．

　　When Anderson looked at the station clock it was ten to two．The train was already twenty minutes late．Walking up and down the platform（站台），he became more and more impatient（不耐烦）．

　　The train came at last, just when Anderson decided to leave the station．Only two people got out-an old farmer with his dog, and a young woman．

　　Anderson said to himself that obviously Professor J．Maurice had missed the train．Just as he was leaving the station, someone stopped him．He was surprised to see the young woman who had just got out of the train．

　　“Are you Mr Anderson?” she asked．

　　“Why, yes, ” he answered．

　　“I'm Jane Maurice．I'm sorry to have kept you waiting so long．I was told you would be here to meet me．”

Batteries can power anything from small sensors to large systems．While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves．University of Missouri（MU） researchers are developing a nuclear energy source that is smaller, lighter and more efficient．

“To provide enough power, we need certain methods with high energy density（密度）”，said Jae Kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope（放射性同位素） battery can provide power density that is much higher than chemical batteries．”

Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems （M/NEMS）．Although nuclear batteries can cause concerns, Kwon said they are safe．

“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems．”

His new idea is not only in the battery’s size, but also in its semiconductor（半导体）．Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor．

“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure（晶体结构） of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem．”

Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery’s power, shrink its size and try with various other materials．Kwon said that battery could be thinner than the thickness of human hair．

1.Jae Kwon gave examples in Paragraph 4_________．

A．to show chemical batteries are widely applied．

B．to introduce nuclear batteries can be safely used．

C．to describe a nuclear-powered system．

D．to introduce various energy sources．

2.According to Jae Kwon, his nuclear battery _______．

A．uses a solid semiconductor                B．will soon replace the present ones．

C．could be extremely thin                  D．has passed the final test．

3.The text is most probably a ________．

A．science news report                     B．book review

C．newspaper ad                          D．science fiction

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 think 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.”

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 invention

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

4.

Which 0f the following can best serve as the title of this passage?

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?  

William Henry Bragg was born at Westward，Cumberland，on July 2,1862.He was educated at Market Harboroagh Grammar School and afterwards at King William’s College，Isle of Man.Elected as a minor scholar of Trinity College，Cambridge，in 1881，he studied mathematics under the well?known teacher，Dr E．J.Routh.He studied physics in the Cavendish Laboratory during a part of 1885，and at the end of that year he was elected to the Professorship of Mathematics and Physics in the University of Adelaide，South Australia.

His research interests dealt with a great many fields and he was skilled at picking up a subject，almost casually，making an important contribution，and then dropping it again.However，the work of Bragg and his son Lawrence in 1913～1914 founded a new branch of science of the greatest importance and significance，the analysis of the crystal structure by means of X?rays.It is true that the use of X?rays as an instrument for the systematic revelation of the way in which crystals are built was entirely due to the Braggs.This was recognized by the award of the Nobel Prize jointly to father and son in 1915.

He was an honorary Doctor of some sixteen universities，and a member of the leading foreign societies.Many other medals and awards were bestowed upon him among which may be mentioned the Rumford Medal in 1916 and the Copley Medal (its premier award) in 1930.

He was the author of many books，including Studies in Radioactivity，X?Rays and Crystal Structure，The World of Sound，Concerning the Nature of Things，Old Trades and New Knowledge，An Introduction to Crystal Analysis，and The Universe of Light.His favorite hobby was golf.After a life of astonishing productiveness，Sir William Bragg died on March 10,1942.
