When the Farnsworth family moved to their new farm in 1919, eleven-year-old Philo was surprised to find it wired for electricity. This unusual circumstance contributed to his fate — to become an important inventor of the twentieth century.

    By thirteen, Farnsworth had become a self-taught electrical engineer. He was able to fix the farm’s generator(發(fā)電機(jī))when none of the adults could. In 1922, he read an article about a new idea of John Baird, a Scottish scientist, who had been working with the cathode ray tube (陰極射線(xiàn)管) for the transmission of electronic pictures and wanted to attempt it himself.

    Farnsworth studied everything he could find on the subject. Although many older engineers with money backers were already developing television, Farnsworth made a bold decision — he was going to perfect a working model of it before anybody else.

    In college, Farnsworth continued his research with cathode ray and vacuum tubes, but the death of his father, the only money maker in the family, forced him to give up this research and find a job. His first job was for George Everson, with whom Farnsworth discussed his dream of television. While acknowledging the achievements of those who came before, Farnsworth thought that he could get closer. Everson agreed to risk $6,000 for the research.

    Backers came in 1927 to see the first American television, one year after Baird’s. They were astonished to see the image of a single white line resolve itself on the screen before them, and agreed that this new invention was worth putting money into.

    In 1930, Farnsworth won a patent (專(zhuān)利權(quán)) for his all-electronic TV. By the time he died, he had earned over 300 American and foreign patents for electronic and mechanical devices.

1.When Farnsworth was at a young age, he _______

A. had to drop out of school to help on the family farm

B. was sent to school to study electrical engineering

C. wanted to be the first person to invent the television

D. had shown a surprising ability in the electrical field

2.What difficulty did Farnsworth meet when he first began his research on the television?

A. His parents didn’t support his work.

B. He didn’t have enough knowledge in this field.

C. He didn’t have enough money for his research.

D. No one was interested in this research.

3.How old was Philo Farnsworth when he invented the first American television?

A. 11.                 B. 13.        C. 19.       D. 22.

4.From the passage, we can learn that Farnsworth is ______.

A. the first person who worked for the transmission of electronic pictures

B. an inventor who improved on somebody else’s idea

C. an inventor who always came up with an original idea

D. a person who earned over 300 American patents for electronic devices

試題分析:他在少年時(shí)代就在電氣方面顯現(xiàn)出了不凡的才能,13歲就通過(guò)自學(xué)成為了電機(jī)工程師,這就是本文介紹的二十世紀(jì)最重要的發(fā)明家之一------費(fèi)羅•法恩斯沃斯。他是一名多產(chǎn)的發(fā)明家,除發(fā)明了第一臺(tái)能傳輸圖像的機(jī)械式電視機(jī)外,他還發(fā)明了一百多種裝置。

1.D推理判斷題。文章第二段提到他在13歲的時(shí)候通過(guò)自學(xué)成為了電機(jī)工程師,而且能夠修理農(nóng)場(chǎng)的發(fā)電機(jī),由此可知本段講述了法恩斯沃斯在少年時(shí)代就表現(xiàn)出的不凡才能,故答案選D。

2.C細(xì)節(jié)理解題。根據(jù)文章第四段可知當(dāng)他在研究改進(jìn)電視機(jī)時(shí),家里唯一掙錢(qián)的父親去世了,他沒(méi)錢(qián)進(jìn)行研究,所以正確答案為C。

3.C細(xì)節(jié)理解題。根據(jù)文章第一段When the Farnsworth family moved to their new farm in 1919, eleven-year-old Philo was surprised to find it wired for electricity. 和倒數(shù)第二段Backers came in 1927 to see the first American television,可以判斷當(dāng)他發(fā)明一臺(tái)美國(guó)電視機(jī)的時(shí)候是19歲,故答案選C。

4.B細(xì)節(jié)理解題。由文章第三段he was going to perfect a working model of it before anybody else.可知他是在別人研究的基礎(chǔ)上進(jìn)行了改進(jìn)完善,由此可知答案選B。

Many people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive (毀滅性的).

A series of such storms struck the US last month and caused very serious damage and human pain.

Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.

Predictions are improving. “We’ve gotten better over the years, especially the last few years,” says Phil Klotzback, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right,” Klotzback says.

    First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the air containing drops of water cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.

If wind speeds reach 40 miles per hour, the system is called a “ tropical storm”, and it gets a name. At 75 miles per hour, it becomes a hurricane. Hurricanes that hit the US start when a thunderstorm forms off the coast Africa. Storms also develop over tropical waters in other parts of the world.

On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or a bit higher.

The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September and October.

According to the text, hurricanes usually ________.

 A. form off the coast of Africa and America

 B. hit parts of the world in summer and autumn

 C. cause sea winds to rise and blow over the sea

 D. strike the US but cause no damage

The underlined word “evaporates” (in Paragraph 5) probably means “________ .”

   A. begins to move      B. gets lost      C. becomes hot   D. changes into a gas

Which of the following about the information of a hurricane is the correct order?

   a. The ocean water evaporates and goes into the air.

   b. Heat creates energy and causes winds to increase.

   c. The vapor cools.                        

d. The ocean water is warm enough.

   e. The vapor changes back into liquid.       

f. This course gives out heat.

   A. a, d, e, b, c, f       B. a, b, c, f, d, e      C. d, a, c, e, f, b     D. d, a, b, c, e, f
