For over one hundred and fifty years, Americans of all social classes have worn blue jeans. 1. Whether they are worn for work or for fashion today, Strauss’ invention continues to be popular not only among Americans but also among people around the world.
Levi Strauss was born in Germany in 1829. 2. He grew up in Kentucky before moving to New York in 1847. Before becoming an American citizen and moving to the West in 1853, Strauss worked in his brother’s dry goods business. This gave him a chance to produce his famous invention. After the gold rush of 1849, Strauss decided to move to the West to seek his fortune.
Strauss did not want to be a person who searched an area for minerals. Instead, he knew he could make a good living by selling supplies to the miners. At first, he planned to sell sewing supplies and cloth. 3. When he heard miners complaining that their clothes were easily broken or they usually tore their pockets during mining, he decided to use a special fabric to make pants for the miners. These pants proved so popular that he quickly ran out of materials to make more.
In 1873, Strauss received a letter from a Jewish tailor named Jacob Davis who had invented a process of connecting pockets with copper rivets(铆钉). This made the pants last a long time. Because Davis did not have the money to patent his idea, he offered to share it with Strauss if Strauss would agree to pay for the patent. 4.
By the time Strauss died in 1902, he had made a great contribution to American fashion.
5. The business has been growing ever since and Levi Strauss' company is now one of the largest clothing companies in the world.
A．As a young boy, he moved with his family to the United States.
B．Nobody knew what kind of material was suitable.
C．He did and Levi jeans have been made with metal rivets ever since.
D．However, he did not get much business for those products.
E. He also made a great contribution to America's clothing industry.
F. Since they were invented by Levi Strauss, they have become a symbol of American consumer culture.
G. As the business grew, Strauss got much money from it.
Food safety will become the food industry’s key target as the nation tries to adopt international food standards. The National Development and Reform Commission, the Standardization Administration of China, the Ministry of Agriculture and six other departments announced their 2004-05 development programme for national food standards over the weekend.
China is conducting a rectification (整顿) within two years. Inspectors will search for all known banned materials in food production. To reduce trading barriers, China will raise the ratio of adopting international standards in the food industry to 55 percent from today’s 23 percent. “Safety is the first consideration for anything entering people’s mouth followed by its nutritious value,” said Hao Yu, secretary-general of the National Food Industry Standardization Technique Committee. He added the usage of food addictives (添加剂) will be a major field for consideration in setting the new standards. On-the-spot checks during the past two years have shown the abuse (滥用) or misuse of addictives in food production and processing has become the biggest threat to food safety. In one case, talcum (滑石粉) powder was found in flour products, which is outlawed according to national food standards.
“At present there are no methods or standards to test the content of talcum powder in flour,” said Shang Yan’e, an official with the national watchdog on grain and oil inspections. Under the guidelines, all banned addictives will be recorded as inspections increase, Relevant departments have allocated (分配) funds to conduct risk evaluations on current food addictives to fix the limits of their usage. China will adopt international advanced techniques and standards so as to find out the harmful materials in food within a shortest period.
1.China will raise the ratio of adopting international standards in the food industry by _____.
A．55% B．32% C．23% D．78%
2._________ is the second consideration for anything people eat according to the passage.
A．Safety B．Value C．Nutrition D．Addictives
3.What does the passage mainly talk about?
A．Addictives are dangerous to people’s health.
B．Chinese food will be as safe as foreign food.
C．New food safety standards are to be fixed.
D．Food safety is a major concern in present China.
Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.
1.What is the text mainly about?
A．The terrible conditions in the Antarctic.
B．A special fish living in freezing waters.
C．The ice shelf around Antarctica.
D．Protection of the Antarctic cod.
2.Why can the Antarctic cod live at the freezing temperature?
A．The seawater has a temperature of - l.88℃
B．It loves to live in the ice-salt mixture.
C．A special protein keeps it from freezing.
D．Its blood has a temperature lower than -2.05℃
3.What does the underlined word “it” in Paragraph 5 refer to?
A．A type of ice-salt mixture. B．A newly found protein
C．Fish blood. D．Sugar molecule.
4.What does “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?
A．sugar B．ice C．blood D．molecule
