The back door of the ambulance(救护车) was suddenly shut and the driver ran to the front, jumped into his seat, and started the engine. Inside were the1 parents, Mr. and Mrs. Green, the mother holding their baby daughter Ally. The little girl had 2 food stuck in her throat and could hardly breathe.

    The driver, Mr. White, 3 his siren (报警器) and flashing light, and started speeding towards the nearest hospital, fighting against4. The cars ahead of him pulled out of the way as he drove through the 5from the back of the 6 the parents were shouting at him to    7 , since Ally had almost stopped breathing. In front of him he saw some traffic lights, with the red "STOP" light shining. Mr. White knew that he had no time to 8 , so he drove straight past the traffic lights, looking to his left and right as he did so.

    Coming towards him from his right was a taxi. The driver had the windows 9, since the car was air-conditioned, and he was playing his radio. He did not10the ambulance. The lights were green, so he drove straight on into the path of the ambulance.

    Mr. White tried to stop his ambulance but it was too late. It hit the taxi. Everybody was shaken but no one was hurt. Mr. White looked to see how little Ally was. He was astonished to see relief instead of 11on the faces of the parents.

    "Look!" cried Mrs. Green. "She is 12again."

    "It must have been the crash." said her husband. "It 13 the food out of her throat." The baby's color was turning to14 , and she was crying in a loud but healthy 15.

    They were all joyful, and quite forgot about the accident, the taxi, and the lines of cars all around them.

There's nothing better than having a sweet sleep after a full day of tiring work. Like people, animals need to rest after working hard, too. Some animals sleep in water while others dig holes under the ground. Some even sleep high in trees or under the leaves. Although they sleep in different ways, all of them find ways to have a good rest. 

Some animals in the sea sleep in strange ways. For example, fish sleep with their eyes open. They seem to look ahead far into the sea when they take breaks. Sea otters（海獭）sometimes sleep in beds of the plants that grow in the sea. This keeps them from moving away. Parrotfish（鹦嘴鱼）blow something from their mouths when they are ready to sleep. Then a bubble（气泡）will be formed around them. The bubble protects them from danger while they sleep. 

Some animals sleep under the ground. Chipmunks（花栗鼠）sleep curled up（蜷缩）in a ball. Their beds are made of leaves and grass. In winter, they sleep for two weeks and wake up to eat the food. Then they go back to sleep for another two weeks before waking up again. Some desert frogs（青蛙）dig underground holes during the hot and dry season. A frog may stay in its hole for months. 

High above the ground, monkeys find places in trees each evening before they sleep. The tall trees help to keep monkeys safe during the night. Some insects（昆虫）even sleep under the leaves that will be their next meal. A bee may climb down into a flower to rest. When it climbs out the next morning, it rests well and is ready for work.

"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 (悬崖), 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 (海湾). 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."
