  The word, “photography”, was first used in 1839. It comes from the Greek words that mean “to write with light”. But photography could only give people static pictures. So scientists were trying hard to find ways to make pictures that can move. They made lots of experiments, but failed again and again. It was Eadweard Muybridge who finally succeeded. He was the first photographer to try this successfully. But how did he make it? It was an interesting story.

Back in 1872, people didn’t know exactly (确切地) whether all four of a horse’s hooves (蹄) left the ground at the same time when it was running. A gentleman called Leland Stanford made a bet with his friend about it. Most people believed that a horse always had one hoof on the ground, or it would fall over. But Stanford didn’t think so.

At that time, it was hard to know who could win the bet, because a horse’s legs move so fast that it is impossible to tell just by looking. So they needed a way to record the movement of a running horse. Then Stanford offered $25,000 to the famous photographer, Muybridge, to help find the answer. In the beginning, Muybridge failed to get clear images, but he didn’t give up. He continued to improve his cameras. In 1878, after many experiments, he managed to get a sequence (连续) of 12 photos. One of them clearly showed that all four of the horse’s hooves were off the ground at the same time. And when the photos moved fast, people could see a horse running.

Though is usually considered as the person who created the first movie in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison’s invention.

53. The underlined word “static” in Paragraph 1 most probably means _______.

A. pretty            B. dark             C. moving          D. still

54. What did Leland Stanford make a bet with his friend about?

  A. Whose horse ran faster.

  B. whether a horse would fall over while running.

  C. whether it was possible for scientists to make moving pictures.

  D.Whether a horse’s hooves all left the ground at the same time while running.

55. Muybridge finally found the exact answer to the bet in _______.

  A. 1839            B. 1872            C. 1878          D. 1889

56. The passage mainly tells us _______.

  A. that Thomas Edison created the first movie .

  B. that Eadweard Muybridge created the first static pictures

  C. how photography helped people know more about animals

  D. how Eadweard Muybridge got pictures of motion (移动) successfully

  People have always wanted to speak with animals.There are many books about this, especially children books.Now there are also movies, such as Dr.Doolittle.When you watch animals, it seems clear that they can communicate with each other.Many people wonder why people can’t also communicate with them.

  Scientists know how some animals communicate.Bees, for example, use their bodies.They do a kind of dance to give information about food.Birds, on the other hand, share information with sounds.They use certain sounds to protect their homes and to stay together when they fly.Some male(雄性)birds use lovely songs to attract a female(雌性).Other animals communicate with both body movements and sounds.For example, dogs wag(摇摆)their tails(尾巴)when they are happy, and they bark(吠)when they are excited.

  People used to think it was possible to teach human language to animals.Parrots and other birds, for example, can learn to say words.But the birds just repeat the words.They don’t understand them.Some American scientists tried to teach English to chimpanzees, close relatives of human beings.However, this was impossible.Chimpanzees can’t move their mouths the right way.They could never learn to speak like people.

  Then scientists tried to teach human language to chimpanzees in other ways.Some tried with American Sign Language(ASL).Others tried with a simple computer.But chimpanzees could only learn to use a few words.They could never learn to use grammar.Their brains are very different from the brains of human beings.

  Now some scientists are studying the same points between human and animal language.In fact, some animals use sounds like people do.Dogs, for example, use an unpleasant, low sound to tell other dogs to stay away.People, too, use that kind of voice to say the same things.A dog’s noisy bark communicates that something is happening.People use the same high tone when they shout,“Watch out!”

  Scientists want to understand the language of other animals, such as whales and bears.To do this, they go out to the animals’ natural homes.They watch the animals for days or even years.They take pictures and make tapes recordings and share the information with other scientists.In this way, they hope to learn more about the way animals communicate, and maybe someday we’ll be able to communicate better with them.

(1)

[  ]

A.

but they don’t really know the meaning

B.

and they make up new words, too

C.

and they use grammar, too

D.

[  ]

A.

Which of the following is TRUE?

[  ]

A.

Bees communicate by making a noise

B.

Dogs wag their tails when they are angry.

C.

Chimpanzees can learn to use some grammar.

D.

Birds use sounds to stay together

(4)

  One day, a lawyer's wife fell ill and he went to get a doctor. The doctor was glad to come to see the woman and to do what he could for her. But before he went into the house he stopped. He knew it was known to all that the lawyer would not pay others when he should. So he said to the man, “But if I do cure your wife, I'm afraid you won't pay me.”
