听力原文： Cats have been popular pets for thousands of years. The ancient Egyptians are thought to have been the first to keep cats in their homes. Today, people like cats for many reasons. Cats are easy to care for. They are soft and beautiful and they can catch mice!

A cat is a natural hunter. It has a good sense of hearing. Its sense of smell is well developed, too. Its eyes can detect the smallest movements. With its powerful legs it can run after its prey and jump to catch it.

A pet cat that is fed every day does net need to hunt for food. But it may go after a mouse anyway. This is because hunting is an instinct in cats. They are born with this ability.

Cats have other instincts as well. They purr when they are happy. They arch their backs and puff up their fur when they are afraid. Cats also scratch objects with their front claws. Some people think cats scratch to sharpen their claws. Others think this action helps exercise their legs and feet. Both reasons may be true.

There are many breeds of cats. Some have long hair, others have short hair. Their coats can have different colors and patterns. Cats have different personalities, too. Some use their voices a lot. Others are silent. Some are shy, while others are friendly. Many people enjoy having these animals as companions.

听力原文：Most dogs can be taught to tolerate cats if their owners are willing to be patien

听力原文： Most dogs can be taught to tolerate cats if their owners are willing to be patient and consistent. Some dogs take longer to train than others and the difference is usually due to the dog's level of "prey drive".

Nature designed the predators to chase and catch smaller animals for food. Although dogs have been domesticated for thousands of years, they still act upon the instincts nature gave them. Through generations of selective breeding, people have modified these instincts. By decreasing the effects of some and enhancing the effects of others, we've been able to develop a wide variety of different breeds of dogs, each meant to serve a different purpose or perform. a certain function.

A dog's instinct to chase and catch something is called his prey drive. Throw a stuffed toy to a puppy and watch his prey drive in action as he chases it, catches it, and then shakes it to pieces. Breeds and individual dogs vary in the intensity of their prey drives. Some breeds are created specifically for killing other animals. Most terriers, for example, are intended to kill rats and they have very high prey drives.

In other breeds, the prey drive can be altered to suit an entirely different purpose. Therefore, there must be effective ways to train a dog with a high prey drive to live peacefully with cats and other small pets. For example, by giving the dog extra attention and even special treats when the cat is in the room, the dog soon learns that having the cat around means very good things are going to happen to him! He will be happy to get along with the cat harmoniously and his prey drive will be lowered.

听力原文：Dr. Williams in New York carried out a study of cats, which had fallen out of win

听力原文： Dr. Williams in New York carried out a study of cats, which had fallen out of windows of apartment blocks. Nine out of ten survived a fall of two storeys or more. One cat fell from a flat on the thirty- second floor and only lost a tooth. Interestingly, the cats were most at risk from injury or death if they fell from the seventh floor. Falling from either a lesser or greater height gave them a better chance of survival.

What is the significance of the seventh floor？ The study shows that this is the distance cats take to reach their terminal speed, i.e., the final speed that does not change once it is reached. After the seventh floor, it may be that they relax and spread out their legs like a flying squirrel. This would slow them down and allow their muscles to absorb more of the force of impact, which would reduce the damage.

Cats also have a very well-developed sense of balance. They can change position while falling so that they land on their feet. This has the advantage of spreading the force of impact with the ground over four legs and so does less damage to each leg.

(33)

A．Nine out of ten.

B．One third.

C．Elven out of thirty.

D．One fourth.
