名校课堂系列答案
Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out.” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine –one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father's warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the center of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen:
“ENTER NAMES
VOYAGER 1: …
VOYAGER 2: …”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED（自动回收程序已启动）.”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow (光芒), until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
“TRANSPORT SUCCESSFUL. DESTINATION（目的地）: MARS. RETRIEVE DATE: 2025.”

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(发电机), 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 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.
