Many people know the names Alexander Graham Bell and Thomas Edison. However, most people don’t know the name of the man who invented the television, Philo Farnsworth.
Philo Farnsworth was born in 1906 and grew up on a potato farm. As a boy, he loved to learn about science, and he read a lot of science books. When he was only thirteen years old, he drew a picture of a machine that could send pictures as radio sends sounds. He got the idea from the way the potatoes were planted in the field. The potatoes grew in long lines, side by side. This made a shape in Philo’s mind. This shape helped Philo think of a way to send the TV picture onto a piece of glass. But he was poor, so Philo could not try to make his idea into a machine at that time.
Later, Philo worked at many different jobs. He worked with trees. He worked on broken radios. He worked on trains. He also worked as a street cleaner. At last, two rich men heard about his idea for television, and they gave him the money to make it. On September 7th, 1927, they watched Philo test the machine he built. When Philo turned on the machine, a small line could be seen on the glass. Philo said, “There you have it, electric television.”
Later, a big company, RCA, said they had made the first television. Philo had to spend a lot of money on lawyers to fight them. Finally, he won. Then, World War Two started in 1939. During the war, Philo spent a lot of money helping the US army instead of building up his television company. After the war, other bigger, richer companies started making televisions. In the end, Philo had to sell his company.
【小題1】Why does the author mention Bell and Edison at the beginning of the text?

A.To remember both of them.B.To prove their wisdom.
C.To introduce the topic of the text.D.To explain their relationships.
【小題2】According to the text, how old was Philo when he finished his invention of TV?
A.27 years old.B.21 years old.C.33 years oldD.39 years old
【小題3】Philo Farnsworth got the idea for TV from ______.
A.the radioB.science booksC.potato fieldsD.a machine
【小題4】 The underlined part “building up” in the last paragraph probably means “______”.
A.startingB.sellingC.putting upD.making bigger
【小題5】Which is the correct order of the following events?
a. Two rich men gave Philo money to do experiments.
b. Philo sold his own company.
c. Philo beat RCA in law.
d. Philo fixed broken radios.
e. Philo showed his invention to others.
A.d, a, e, c, bB.e, d, c, b, aC.d, c, e, b, aD.a, c, b, d, e

In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about.  It is the story of someone who tried to look as rich as his neighbors.

The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $ 125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants. Momand and his wife also hired a servant and gave big parties for their new neighbors. 

It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They had to move back to an apartment in New York City. Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “Keeping up with the Joneses” because “Jones” is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with rich lifestyle of the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.

People never seem to get tired of keeping up with the Joneses. And there are “Joneses” in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.

Some people want to keep up with the Joneses because they ______.

A.want to be as rich as their neighbors

B.want others to know or to think that they are rich

C.don't want others to know they are rich

D.want to be happy

It can be inferred from the story that rich people like to ________. 

A.live outside New York City    B.live in New York City

  C.live in apartments            D.live with many neighbors

What's the author's attitude to keeping up with the Joneses?

A.Negative.                   B.Positive.

C.Supportive.                  D.Objective.

科目:高中英語 來源: 題型:閱讀理解

Thirty- two people watched Kitty Genovese being killed right below their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellowman?

  “Not so,”say scientists John Barley and Bib Fatane. These men went beyond the headlines to research into the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency(緊急情況). Suppose you see a middle-aged man fall to the side - walk. Is he having a heart attack? Is he in a coma(昏迷) from a headache? Or is he about to sleep off a drunk? Is the smoke coming into the room from a leak(漏洞)in the air conditioning? Is it “steam pipes”? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency. Second, and more important, the person faced with an emergency must feel personally responsible(負責任的). He must feel that he must help, or the person won’t get the help he needs.

  The researchers found that a lot depends on how many people are around. They had college students in to be “tested.”Some came alone. Some came with one or two others. And some came in large groups. The researchers started them off on the “tests.”Then they went into the next room. A curtain divided the “testing room”and the room into which they went. Soon the students heard a scream, the noise of bookshelves falling and a cry for help. All of this had been prerecorded on a tape recorder.

  Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.

  In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.

  Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were shocked, they sweated, and they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.

60. The purpose of this passage is ________.

 A. to explain why people fail to act in emergencies

 B. to explain when people will act in emergencies

 C. to explain what people will do in emergencies

D. to explain how people feel in emergencies

61. Which of the following is NOT true?

  A. When a person tries to help others, he must be clear that there is a real emergency.

  B. When a person tries to help others, he should know whether they are worth his help.

  C. A person must take the full responsibility for the safety of those in emergencies if he wants to help.

  D. A person with a heart attack needs the most.

62. The main reason why people fail to act when they stay together is that ________.

  A. they are afraid of emergencies

  B. they are not willing to get themselves involved

  C. others will act if they themselves hesitate

D. they do not have any direct responsibility for those who need help

63. The author suggests that ________.

  A. we shouldn’t blame a person if he fails to act in emergencies

  B. a person must feel guilty if he fails to help

  C. people should be responsible for themselves in emergencies

D. when you are in trouble, people will help you anyway
