Do dogs understand us?

Be careful what you say around your dog. It might understand more than you think.

A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee.

In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

The correct object was chosen in seven out of ten tests, suggesting that the dog had worked

out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.

Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品種)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

1. From paragraph 2 we know that __        .

A. animals are as clever as human beings

B. chimpanzees have very good word-learning skills

C. dogs are smarter than parrots and chimpanzees

D. dogs have similar learning abilities as 3-year-old children

2.Both experiments show that             .

A. Rico is smart enough to get all commands right

B. Rico can recognize different things including toys

C. Rico has developed the ability of learning mathematics

D. Rico won't forget the names of objects once recognizing them

3. Which of the following statements is true?

A. Rico has a better memory partly because of its proper early training.

B. The purpose of the experiments is to show the border collie's mental abilities.

C. The border collie is world-famous for recognizing objects.

D. Rico is born to understand its owner's commands.

4.What does the writer want to tell us?

A. To train your dog.                  B. To talk to your dog.

C. To be careful with your dog.        D. To be friendly to your dog.

I want to tell you a story that changed my life many years ago. We were living in College Station, Texas and my wife and I were on our way home from Houston, Texas one Saturday morning. We decided to stop at a local restaurant to get something to eat since we had enough time. When we finished, we got back into our car and before I started it, we noticed a homeless man standing in front of the building. His clothes were worn and it looked as though he didn’t have any money. It was cold and I was sure he wanted something warm to drink; however, it was not this that I remember, because that is not what "moved" me. A dog was also walking up to the front of the building. Being a dog owner, I knew that the dog was a mother, and that she had just had some pups (小狗). She was hungry and weak and I felt bad for her. I knew if she didn’t eat soon, she and her pups would not live. People walking by didn’t even notice her. She was not as pretty and clean as most dogs, but she still deserved (值得) better. We still did not do anything, but someone else did. The homeless man, who I thought could not afford anything to eat, went into the store and bought dog food with all the money he had.

B.The homeless man wore worn clothes on cold days.
C.The homeless man bought food for a dog with all his money.

【小題4】What can we conclude(得出結論) from the passage?
A.The author was so hungry that he went into the local restaurant to eat.
B.The author didn’t understand what the homeless man did.
C.The dog shouldn’t be taken care of carefully because it looked ugly.
