【推荐2】It was a freezing cold winter night. Coming near the town to look for food, a very hungry wolf met a house dog. The wolf saw that the dog was fat and comfortable so he asked, “Cousin dog, do


you know where I can I find some food?”

“Oh, there is always food in my house,” said the dog. “My master gives me plenty of meat.”

“Master?” said the wolf, “What’s that?”

“The man I work for,” said the dog, “My job is easy. I bark and keep thieves away from the


house. It’s a good life. Why don’t you try it?”

“Yes,” said the wolf. “Your life sounds much better than living in the cold woods. I’d like a roof over my head. I’ll come with you and work for your master.”

As they ran toward the town together, the wolf saw a mark on the dog’s neck.

“What’s that?” he asked.

“Chain?” asked the wolf.” You mean that you are not free? You can’t go where you want to?”

not bad. And think of all the food I get! Where are you going?”

Why are dogs our best friends? Maybe because they can understand our words much better than we thought, according to a study in Hungary. It found that dogs understand not only what we say,but also how we say it.

"The results were very exciting and very surprising," said the researcher Attila Andies,from Eotvos Lorand University in Budapest.

For the study,the researchers first trained 13 dogs for months. The dogs had to sit quietly inside machines,so that the researchers could check their activity.

Then the researcher put headphones on dogs and played people's voices to them. There were four different voices. Some were positive words,such as "well down" , or neutral(不带感情色彩) words like "however". The words were also in different tones( 音调). Some were positive( 积极的) and some were neutral.

Brain scans( 扫描) showed that the dogs could recognize( 辨认) words,as well as the tone of words, much like people do. The positive words with a positive tone brought the stronger activity in their brain's reward centers(反应中枢).

"It shows that for dogs, a nice phrase can work very well as a prize, but it works best if both words and tones match, "said Andies.

They also found that dogs deal with meaningful words with the left side of the brain and tones with the right. Human brains work in the same way.

"It gave us a new understanding of language," said Andies. That is, not only do humans understand the meaning in words, other species(物种) do too.
