Ray Tomlinson was born in New York State. He sent the world’s f 1. email and let us have the use of the @ symbol in electronic communications. Tomlinson wrote a program in 1971 that a 2. messages to be exchanged between different computers. Before that time, electronic messages had only been exchanged between people using the s 3. main unit.

At the time of his invention, Tomlinson was researching possible uses for the ArpaNet—the US military (軍方) network that formed the base of the Internet, and showed an i 4. in improving the use of ArpaNet’s “mailbox(郵箱)”, which made users send messages to the mailboxes possible. In the past, people had to print out the message and p 5. it in the mailbox. This achievement made a great difference in people’s life.

Tomlinson also came up with the i 6. of using the “@” symbol to separate the name of the receiver from the name of the host, creating the standard still used today. Although it had a history of o 7. forty years, Tomlinson said email had not changed much since its invention.

Tomlinson studied electrical engineering at Rensselaer Polytechnic and t 8. got his masters (碩士學(xué)位) at Massachusetts Institute of Technology. He joined a company called Bolt, Beranek, and Newman in 1967, and stayed there the r 9. of his life. He died at the age of 74. The company was later acquired (收購) by Raytheon.

“A true technology pioneer and his work changed the w 10. the world communicates.” Ratheon said. “It is with great sadness we know the passing of our friend.”

Tuesday， Jan. 6， 9：50 p.m.

We were sitting in our warm living room. The TV was on， and everything was peaceful. Suddenly the light went on and off for a few times and then went out completely. Then the rain started， and everything went black. We found the flashlight and some candles and went to bed.

Wednesday， Jan. 7， 7：30 a.m.

My first thought after waking up was that it was pretty cold in my bedroom. Clearly， the power (電力供應(yīng)) didn’t come back. After I looked out of the window， I felt even sadder： it was still raining heavily. The room was becoming colder and colder. We had no idea when the power would come back， so my wife started a fire in the fireplace.

Thursday， Jan. 8， 12：30 p.m.

The snow started. The poor trees now had to carry the heavy snow. The storm seemed to last (持續(xù)) and we had nothing to do but stay at home.

Friday， Jan. 9， 6：00 p.m.

Still no power. Even though we lit (點燃) a few candles， it was still difficult to do anything in their weak light. I was sitting near several candles， but I had trouble reading.

Saturday， Jan. 10， 1：00 p.m.

The storm stopped this morning， and I drove my car to look for an open store. The trees along the roads were broken.

“Please take my penny,” said Maggie to old Dan, the fisherman, who sat on a bench repairing his nets.

Her brother Andrew drew her back, whispering, “Maggie, he is not a beggar (乞丐)!”

But Maggie paid no attention. “Please take it,” she said again. Old Dan smiled, and took it. “Thank you, little miss,” he said, “It is kindly meant.”

After that, Maggie went to the beach to gather shells. She never thought how fast the hours were passing until being tired, she sat down on a rock beside a little pool. Soon she was scared by a noise near her, and Dan’s large dog Rover jumped down from a rock!

He licked her hands and made a loud noise, and then began gently to pull her coat. “Rover wishes me to come away, I see,” she said, and she rose from the rock and began to go home. However, that was not so easy as she had expected. She found the places she had gone down easily very difficult to climb up, and as the tide (潮水) had been coming in for some time. She found some of the stones wet and smooth.

What could poor Maggie do? She felt sad and cried, but the waves made a much louder noise than she could make, and perhaps she would have been drowned (淹死) without good wise Rover.

Rover jumped upon a big stone and raised his loud bark until even the waves could not drown it.

The fisherman had taken his nets to the top of the cliffs (懸崖), and was laying them out in the sun when he heard the loud barking of a dog. He felt sure that it was Rover, and Rover in trouble, so, going to the edge of the cliffs, he looked over. There he saw it all—Rover barking for help, and the little child standing beside him.

“Bless her! It is the little one that was so kind-spoken to me this morning!” he cried, and he hurried to his sons’ home.

“Quick, boys, quick!” he said. “Get to the boat, and row fast to the bay (海灣). There is a poor child there just waiting to be drowned.” The fishermen lost no time, and soon little Maggie and Rover were rowed safely to land! Old Dan was waiting there to lift her out, and give her into her mother’s arms.

“It was the penny that did it, madam,” he said to Mrs. Weston later. “I saw Rover looking at her when she put the penny so kind-like into my hand—just as if he would have said, ‘Rover will be your friend now, little girl.’ And I am thinking he had been looking after her all the day, for he never came near me after that.”

Some years later, Rover came to Maggie’s home with a little note, in which was written— “Will Maggie help Rover?—his master is dead.”

1. Which word can best describe Maggie?

A. Funny. B. Helpful. C. Creative. D. Silly.

2.Who rowed Maggie to land safely?

C. Rover lived with Old Dan until his master died

D. Maggie became Rover’s master at once after she was saved

4. What can we learn from the passage?

A. One kind act brings another.

B. You should act and speak the same—kindly.

C. One person’s pleasure may be another’s pain.

D. People often forget what is really important in our lives.
