题目内容

  In 1931, it was discovered that some unknown substance present only in certain foods was necessary for good health. This substance was what is now called “Vitamin A”.

  Vitamin A's biggest job is to keep the eyes going. Without it, people and animals get “night blindness” and eye problems. Lack of Vitamin A for a long time can even cause total blindness, particularly among children. This had a chance to be tested in Denmark during World Was I. Because of food shortage, many children had to eat man-made butter and skim milk(脱脂奶), which contains no Vitamin A. Soon, they developed eye diseases. It was after they were given real butter and whole milk that they had no eye problems.

  After Vitamin A was discovered, it took more than thirty years of experiments for scientists to be able to get a small amount of pure Vitamin A. Vitamin A is manufactured and is used successfully to treat a number of diseases. You can easily get enough Vitamin A by eating a variety of food. Good sources of Vitamin A are liver(肝脏) from some animals and dairy products such as milk and cream. Not only many vegetables contain carotene(胡萝卜素), from which your liver can make its own Vitamin A, some fruits also provide carotene which helps your liver to supply Vitamin A. As long as you are getting Vitamin A from food you won't need to take any extra in the form of liquid or pills.

(1)According to the passage, if Vitamin A is not provided enough, which of the following are likely to be affected most se riously?

[  ]

A.Adults.
B.Animals
C.Children.
D.Plants.

(2) Vitamin A is a very. important substance mainly because it _______.

[  ]

A.is hard to made

B.helps to keep one's eyes healthy

C.can make butter more delicious

D.can not be produced in large quantity

(3) What made the children in Denmark get eye diseases during World War I?

[  ]

A.The war they experienced.

B.Their poor housing conditions.

C.The experiments on food.

D.The lack of Vitamin A in their food.

(4) According to the text, the following are all good sources of Vitamin A except _______.

[  ]

A.animal liver
B.flour
C.vegetables
D.milk

(5) Which of the following could be the best title of the passage?

[  ]

A.The Discovery of Vitamin A.
B.Some Unknown Substance.
C.Sources for Vitamin A.
D.Vitamin A.
答案:C;B;D;B;D
解析:

1. C  由第二段的“Lack of Vitamin A for a long time can even cause total blindness, particularly among children.”

2. B  由第二段中的第一句可知。

3. D  由第二段可得知。

4. B  由第三自然段,可知维生素A来自动物的肝脏、奶制品、蔬菜和水果,未提到粮食,利用排除法,故选B项。

5.D  该题为主旨大意题。短文从头到尾都是谈Vitamin A。因此D为最佳选项。

  Thomas Alva Edison lit up the world with his invention of the electric light. Without him, the world might still be a dark place. However, the electric light was not his only invention. He also invented the phonograph, the motion picture camera, and over 1,200 other things. About every two weeks he created something new.

  Thomas A. Edison was born in Milan, Ohio, on February 11,1847, His family moved to Port Huron, Michigan, when he was seven years old. Surprisingly, he attended school for only two months. His mother, a former teacher, taught him a few things, but Thomas was mostly self - educated. His natural curiosity led him to start experimenting at a young age with electrical and mechanical things at home.

  When he was 12 years old, he got his first job. He became a newsboy on a train that ran between Port Huron and Detroit. He set up a laboratory in a baggage car of the train so that he could continue his experiments in his spare time. Unfortunately, his first work experience did not end well. Thomas was fired when he accidentally set fire to the floor of the baggage car. Thomas then worked for five years as a telegraph operator, but he continued to spend much of his time on the job conducting experiments. He got his first patent in 1868 for a vote recorder run by electricity. However, the vote recorder was not a success. In 1870, he sold another invention, a stock - ticker, for $ 40,000.A stock - ticker is a machine that automatically prints stock prices on a tape. He was then able to build his first shop in Newark, New Jersey.

  Thomas Edison was totally deaf in one ear and hard of hearing in the other, but thought of his deafness as a blessing in many ways. It kept conversations short, so that he could have more time for work. He called himself a “two - shift man” because he worked 16 out of every 24 hours. Sometimes he worked so intensely that his wife had to remind him to sleep and eat.

  Thomas Edison died at the age of 84 on October 18, 1931, at his estate in West Orange, New Jersey. He left numerous inventions that improved the quality of life all over the world.

  Dior was born in Normandy in 1905, and his family's original plans for him included a career in the diplomatic service, but by the time he was twenty-three, with his parents' money, he opened a small art gallery in Paris.By 1931, the money had been used up.Dior's friends in the art gallery , asked him to draw and he took his first step at designing and drawing.His first job was with Lucien Lelong from whom Dior learned his craft(手艺).

  In February, 1947, Dior started the New Look in his first major Paris collection.He was backed by a famous textile producer, Boussac , who looked after the dollars, while Dior looked after the fashions.Dior knew nothing about cutting and sewing, but he was good at fashion design.

  The New Look started an entirely different look to costume, with a tiny waist, a rounded shoulder and a shapely bust(胸围), usually with a low-cut neckline and a long full skirt.To women who had lived through the war years, the femaleness of the New Look was a great success , for people were tired of extremely plain, wartime restrictive fashions.

  It is said that dresses by Dior were "constructed like buildings", but young people were attracted to his design, and all over the western world, manufacturers plunged(投入)into the production of his new style.Dior's revolutionary designs lighted up a whole cycle of fashion , rounded, gentle, feminine, a delight in elegance.A New Look House of Dior opened in 1948followed by one in London.Considered as King of Couture(women's clothing)for years, the Diorempire grew until it covered every country in the western world, and included furs, hosiery , jewelry, perfumes, men's wear and on and on.More than 1, 000 people worked at the Paris headquarters then.

  His sudden death in 1957 when he was 53 years old did not stop the growth of the House of Dior.Even now, so many years after his death, his name is closely connected with fashion throughout the world, and indeed is one of the most recognized names in the world.His first, great New Look, with its long skirts was an expression of freedom in the late 1940s.
