_____ and caught the mouse.

We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting.

Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed (抓伤). Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner.

We all like to cuddle (依偎) inside our bed, and cats do that thing, too. Much as little children like to wrap (用……缠绕) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace.

Usually the tip of the cat’s tail doesn’t draw our attention. But its particular position may also show the cat’s feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.

In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more.

 Birds don’t need lessons in building nests. Fish don’t need coaching to learn how to swim. All animals have instincts. They’re born with natural abilities to do certain things. Wild animals also learn by copying their parents and practicing. And pets learn through training.[来源:学#科#网]

But instincts and training aren’t the only keys to animals’ behavior. Scientists say animals’ thoughts and feelings also influence their actions. Animals often make choices, plans, and sensible changes. They can help others and solve problems. Some even make and use tools!

If animals could talk, what would they say about their thoughts and feelings? A gorilla (大猩猩) born in captivity (关在笼子里) has helped answer that question. Koko, a gorilla, was taught to use sign language. She has learned hundreds of words!

Koko once had a pet cat she named All Ball. “Koko love Ball,” she signed. “Soft good cat.” One time, she blamed the cat for biting her by signing “You bad dirty toilet!” When her pet died, Koko cried. “Sad for sleeping cat,” she signed.

Koko calls herself “fine animal gorilla”. She uses sign language to argue, joke, and ask and answer questions.

“Most animals can’t use words to tell us their thoughts,” says Dr. Jonathan Balcombe. “But Koko shows us that animals have their own ideas and feelings.” Dr. Balcombe is a scientist at the Humane Society of the United States. He says there’s even more to discover about animals through field studies. In field studies, people watch animals in their natural environment.

“Scientists who study animals’ natural behaviors learn how animals live and think,” Balcombe says. “That knowledge can help others respect every animal who shares the planet with us.”

1.The underlined word “instincts” in Paragraph 1 probably refers to the ability that ________.

2.The example of Koko shows that ________.

A. an animal likes to have its own pet    B. an animal can learn to speak through training

C. an animal has the natural ability to speak   D. an animal can speak its mind

3.According to Balcombe, learning how animals live and think can ________.

A. help people care for animals                   B. teach animals to use words

C. train animals to use tools                        D. train animals to be cleverer

4.What might be the best title for the passage?

A. Raising animals as pets                          B. Understanding animals

C. Training animals to speak                       D. Protecting animals from danger

Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new recipe of success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two-thirds of the homes interviewed reported a positive relationship between their cat and dog.

However, it wasn’t all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals were just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.

In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk ‘dog’, and dogs can learn how to talk ‘cat’.

What’s interesting is that both cats and dogs have appeared to develop their intelligence. They can learn how to read each other’s body signals, suggesting that the two may have more in common than we previously suspected. Once familiar with each other’s presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.

The significance of the research on cats and dogs may go beyond pets — to people who don’t get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

 A friend of mine was sitting in the living room one day when his cat dragged in a little “gift” in its mouth—a dead animal of some sort. Taking a closer look, he was surprised to  36 it as the bunny(小兔子) that  37 Mary, the young daughter of the family next door. My friend felt  38 , believing his cat had killed Mary’s bunny.
My quick-thinking friend came up with a plan.  39  from the cat’s mouth the dead animal, which by now was a     40 mess, he put it in the kitchen sink. With a little warm water and some shampoo, he tried to  41 the dead bunny as best he could. Then he took a hair dryer and blowdried the bunny  42 it looked pretty good.
Finally, under the cover of darkness, he crept into the next-door garden and placed it  43 in the cage. He managed to make the bunny look very  44 there in his little box.
The next morning, my friend looked out of the window and noticed a crowd of people  45 around the rabbit hutch(笼). Everyone seemed to be talking and pointing. My friend  46 to go over and act like any normal  47 neighbor and find out what was going on.
When he got there, Mary’s mother said to my friend, “You won’t believe this! It’s a(n)   48 thing! Mary’s bunny  49 a few days ago, and we buried that little bunny right over there…”
Have you ever tried to cover up one wrongdoing with another? Covering up only makes matters  50 .
When we get caught doing something  51 , for example, we may  52 to cover it up with a lie. But just like Mary’s bunny, the result is  53 what we expected. We  54 looking foolish. We would have been better off admitting we were wrong and accepting the  55 . What do you think of it?
