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.

1.Some cats and dogs may fight when ________.

A. they misunderstood each other's signals

B. they look away from each other

C. they are cold to each other

D. they are introduced at an early age

2.What is found surprising about cats and dogs?

A. They eat and sleep each other.

B. They learn to speak each other's language.

C. They observe each other's behaviors.

D. They know something from each other's voices.

3.It is suggested in Paragraph 4 that cats and dogs ________.

A. have common interests

B. have a common body language

C. are less different than was thought

D. are less intelligent than was expected

4.What can we human beings learn from cats and dogs?

A. We should live in peace with animals.

B. We should know more about animals.

C. We should learn to live in harmony.

D. We should learn more body languages.

Many people think of the brain as a mystery.They don’t know much about intelligence and how it works. When they do think about what intelligence is，many people believe that a person is born smart，average，or dumb—and stays that way in the whole life.But new research shows that the brain is more like a muscle—it changes and gets stronger when you use it.And scientists have been able to show just how the brain grows and gets stronger when you learn.

Everyone knows that when you lift weights，your muscles get bigger and you get stronger.A person who can’t lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time.That’s because the muscles become larger and stronger with exercise.And when you stop exercising，the muscles shrink and you get weaker.That’s why people say “Use it or lose it！”

But most people don’t know that when they practice and learn new things，parts of their brain change and get larger a lot like muscles do when they exercise.Inside the cortex (皮层)　 of the brain are billions of tiny nerve cells，called neurons.The nerve cells have branches connecting them to other cells in a complicated network.Communication between these brain cells is what allows us to think and solve problems.When you learn new things，these tiny connections in the brain actually multiply and get stronger.The more you challenge your mind to learn，the more your brain cells grow.Then，things that you once found very hard or even impossible to do—like speaking a foreign language or doing algebra (代数)—seem to become easy after learning them for a period of time.The result is a stronger，smarter brain.

Scientists started thinking that the human brain could develop and change when they studied animals’ brains.They found out that animals that lived in a challenging environment were more “perspicacious”—they were better at solving problems and learning new things.

1.According to the first paragraph，________.

A．the function of our brain is like that of the muscle

B．until now it’s impossible to explain the brain’s mystery

C．many people believe one’s intelligence is naturally determined

D．one’s brain grows stronger as the age increases

2.Training muscles is compared to________.

A．using the brain

B．connecting things in your brain

C．lifting weights

D．doing research about the brain

3.What does the underlined word “perspicacious” in the last paragraph probably mean?

A．Strong.    B．Smart.

C．Popular.    D．Active.

4.The following paragraph will most probably talk about________.

A．the differences between animals’ brains and humans’ brains

B．the relation between human brains and muscles

C．scientists’ findings about animals’ brains

D．how to make your brain smarter through self­development
