Light for the City
Edison and his assistants came to New York to set up an electric power system. They hoped it would provide enough electricity to light up a part of the great city.
They bought several machines with them. These were called generators, which produced electricity power for lamps in Edison’s building.
Soon there were lights for the building. Edison lived in a room facing the street and he often worked over night. The light burned brightly and steadily and he often worked over night. People often came and stopped their horse-drawn carriage to look. Everyone knew that Thomas Edison was in town.
First, the inventor and his assistants produced several large generators. A great deal of power would be needed to light up even a small part of the city.
Then the workers were busy digging deep trenches(沟) in the hard earth below the city streets, and Edison had fourteen miles of wire laid into the trenches. The wire connected each building to a generator.
Setting up an electric power system was not an easy job. It took a year and a half. In September, 1882, the job was finished.
A small group of men stood around Edison inside the power house. The big moment came at last. The inventor, taking a deep breath, pulled a switch. The electric lights flashed up.
“Very good! Very good!” a man nearby shouted to praise Edison for what he had done.
“Sir,” said Edison, “this is only the beginning!” And Edison was right. Soon Edison’s lamp were lighting up cities all over the world.                
【小题1】The generators they brought with them could produce as much as electricity as ______ needed.

Having said goodbye to his parents, Alvin, with his wife and one-year-old son, set off back home． 16 excited, Alvin and Clare talked and laughed happily． And even little Alax  17 from time to time． The family were   18 from trip．
But about three hours later things began to   19 ． It was starting to snow． Alvin sped up the car,   20 to arrive home before dark． But it was too dangerous to drive fast now． Because it was snowing more and more heavily． So Alvin had to   21 down． The snow on the  22 was getting deeper and deeper until it was hard to   23 on it． Their car slipped (滑落) off the way and got stuck in the deep snow   24 the engine refused to start again．
“The snow doesn’t seem to   25 ． Shall we stay in the car waiting to be frozen to death or walk ahead through the snow?” Alvin asked． Clare said she  26 to walk． So they got out of the car with their son and began walking． But   27 was to come． Soon they lost their  28  and had to walk aimlessly on and on．
Night came． They were not afraid of the dark． But they were  29 that poor Alax would die of cold． However, their faith to keep Alax   30 made them filled with courage, warmth and strength． They  31 and rested in turn and then continued their walk． They had countless falls but each time true love encouraged them to rise to their   32 again．
One, two, three, …seven days passed． On the eighth day,   33 at last came from Alvin’s parents, the police and local people． But the young   34 had to have their feet cut off because of the bad frost-bites(冻伤)． Fortunately, there was  35 seriously wrong with little Alax．

The strong fear of high school math is lost here among the blue light of computer screens and the sounds of typing keyboard．

    A fanfare （喇叭声） plays from a speaker as a student passes a chapter test．Nearby another student is watching a video lecture．Another works out a math problem in her notebook before clicking on a multiple-choice answer on her screen．

    Their teacher at Agoura High School, US, Russell Stephans, sits at the back of the room, watching as scores pop up in real time on his computer grade sheet．One student has passed a level, the data shows; another is retaking a quiz．

    "Whoever thought this up makes life so much easier," Stephans says．

    This textbook-free classroom is by no means the norm（常态）, but it may be someday．Slowly, but in increasing numbers, schools across the US are replacing the heavy and expensive textbook with its lighter and cheaper cousin: the digital textbook．

    A digital textbook can be downloaded, projected and printed, and can range from simple text to a course filled with multimedia and links to Internet content．Some versions （版本） must be purchased; others are "open source" —free and available online to anyone．

    Some praise the technology as a way to save schools' money, replace outdated books and better engage students．Others say most schools don't have the resources to join in, or they question the quality of open-source content．

    Paper books still hold the highest percentage of the US textbook market, with digital textbooks making up less than 5 percent, according to analyst Kathy Mickey of Simba Information, a market research group．

    But that is changing, as grade schools follow the lead of US universities and schools in other countries, including South Korea and Turkey．

    California made the largest embrace （拥抱） of digital textbooks this summer when it approved 10 free high school math and science titles developed by college professors．The state left the choice to use them up to individual schools．

    "The textbooks are outdated, as far as I'm concerned, and there's no reason why our schools should have our students pull around these old-fashioned and heavy and expensive books," Governor Arnold Schwarzenegger said this summer．

    But some disagree with the idea that digital textbooks will improve education quality．

    "Keep in mind that with open-source materials, you have to ask: 'Where are they coming from?'" said Jay Diskey, executive director of the Association of American Publishers' school division．"Is it a trusted source? Is it based on real research?"

    Diskey said traditional textbooks offer a comprehensive course, while some open-source texts provide only bits and pieces．"There can be quite a difference of content and accuracy," he said．"In many cases, you get what you pay for．"

A．explain how to use digital textbooks

B．predict the future of paper textbooks

C．describe the current use of digital textbooks and present arguments about it

D．explain the difference between paper textbooks and digital ones

A．He is against getting rid of them．

B．He wants to have them replaced with digital ones．

A．the government shouldn't strengthen the use of open-source digital texts

B．digital textbooks make up for the shortcomings of traditional textbooks．

C．paper textbooks and digital ones both have advantages

D．traditional textbooks have more reliable content
