Empathy(同情心) lets us feel another person’s pain and drives us to help. Do any other animals feel empathy? Scientists recently found that rats(老鼠) do, too.

Most people don’t like rats. In many people’s eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other’s pain.

Scientists placed pairs of rats in plastic cages(籠子) for two weeks. During this time they got to know each other. Then they put one of the rats from each pair into a small container(容器) in the cages. The small container had a door. It was so designed as to fall to the side when the free rat touched it. Many of the trapped(困住的) rats squeaked(吱吱叫) to show their discomfort. The other rats of the pairs could see their suffering friends clearly.

In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats’ favorite chocolate in the cages, but the rats didn’t eat it until they had saved their friends successfully. Scientists also found that female rats seemed to act more empathetic than male rats.

“The results are the first to show that rats take action in response to another’s trouble,” Decety said. “Monkeys and chimpanzees have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural.”

1. A person with empathy is often _____.

A. kind-hearted B. clever C. active D. strong

2. What does the underline word mean in Chinese?

A.休息的 B.睡著的 C.死亡的 D.受苦的

3.Why didn’t the free rats eat the chocolate at first?

A. Because they were full at that time.

B. Because chocolate was not their favorite food.

C. Because they wanted to save the trapped rats first.

D. Because they were afraid that the chocolate was bad.

4.Which of the following animals were NOT mentioned in the passage?

A. Monkeys. B. Cats. C. Rats. D. Chimpanzees.

5.What does the passage mainly tell us?

A. Rats can feel other animals’ pain.

B. Chocolate is rats’ favorite food.

C. Female rats are more empathetic than male rats.

D. Rats are empathetic and can feel each other’s pain.

An elephant and a monkey lived together in the forest. They were good friends, but one day they quarreled with each other. The elephant was very proud because he was very strong; however, the monkey was also proud because he was very quick — he could climb up very quickly.

The elephant said, “It is better to be strong than to be quick.”

“No,” the monkey said, “it is better to be quick than to be strong.”

So they went to a clever owl (貓頭鷹) and asked, “Which is better, to be strong or to be quick?”

The owl said, “Do you see that tall tree with the golden fruit on the other side of the river? You must go and pick the fruit and bring it to me, and then I will tell you.”

So the elephant and the monkey set out. Soon they came to the river. The monkey was afraid of the deep water, and he had to climb up on the elephant’s back. After a while they found the tree. It was very tall and its golden fruit hung high over their heads. The elephant twisted (扭動) his long trunk (象鼻) around the tree and tried to pull it down, but he failed. Then the monkey climbed quickly up the tree. He picked the big golden fruit and threw it down to the ground. The elephant picked up the fruit.

Can you tell, then, which is better, to be strong or to be quick? It took both the elephant’s strength and the monkey’s quickness to get the fruit.

1.Where did the monkey and the elephant live?

___________________________________________________________________________

2.Why did the monkey and the elephant quarrel with each other?

___________________________________________________________________________

3.Who did the monkey and the elephant go to ask?

___________________________________________________________________________
