6.In Eastern Europe,blue jeans symbolize (象征) American culture and"the good life".In Spain they are known as"cowboys".In China,jeans are known as"niuzaiku",also,"cowboy trousers",which means they are connected with the American West cowboy culture and outdoor work.
Jeans are usually made from denim (粗布),but may also be made from other materials.The earliest known cloth for jeans was a thick cotton cloth from the Indians.At first they were working clothes.They became popular among teenagers in the 1950s.Today jeans are a very popular form of casual wear around the world and come in many styles and colors.
Jeans were first made in Genoa in Italy.The trousers were made for the Genoese navy (海军) because they needed trousers which could be worn wet or dry,and whose legs could be easily rolled up while the men were cleaning the ships.These jeans would be washed by pulling them in large fishing nets behind the ship,and the sea water would make them white.
In the 1850s Levi Strauss,a business man living in San Francisco,was selling blue jeans under the"Levi's"name to the coal workers of California.
During World War II,the coal workers liked jeans very much because they were strong and did not tear easily.In the 1950s,jeans became popular with young people in the United States.Wearing of blue jeans by teenagers was the symbol of rebels (反叛者) in TV programs and movies.Some cinemas and restaurants refused to let people in if they wore blue jeans.In the 1980s,jeans finally became high fashion clothing,when famous designers started making their own styles of jeans,with their own labels on them.Sales of jeans went up and up.

10.A few degrees can make a big difference when it comes to food storage.Foods can go bad if they get too warm.But for many of the world's poor,finding a good way to keep food cool is difficult.Refrigerators are costly and they need electricity.Yet spoiled (变质的)food not only creates health risks but also economic losses.Farmers lose money when they have to throw away products that they cannot sell quickly.
But in 1995a teacher in northern Nigeria named Mohammed Bah Abba found a solution.He developed the "Pot-in-Pot Preservation/Cooling System."It uses two round containers made of clay(粘土),A smaller pot is placed inside a larger one.The space between the two pots is filled with wet sand.The inner pot can be filled with fruit,vegetables or drinks.A wet cloth covers the whole cooling system.
Food stored in the smaller pot is kept from spoiling through a simple evaporation (蒸发)process.Water in the sand between the two pots evaporates through the surface of the larger pot,where drier outside air is moving.The evaporation process creates a drop in temperature of several degrees.This cools the inner pot and helps keep food safe from harmful bacteria.Some foods can be kept fresh this way for several weeks.
People throughout Nigeria began using the invention.And it became popular with farmers in other African countries.Mohammed Bah Abba personally financed (资助)the first five thousand pot-in-pot systems for his own community and five villages nearby.
In 2000,the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise(劳力士英才奖).This award recognizes people trying to develop projects aimed at improving human knowledge and well-being.
A committee considers projects in science and medicine,technology,exploration and discovery,the environment and cultural history.Winners receive financial assistance to help develop and extend their projects.The awards are given every two years.The next awards will be presented in late 2016.

A.are in great need of a way to keep food properly

5.There are many festivals in the United States and Canada,among which Thanksgiving Day is a quite special one.Families and friends gather to eat and give thanks for their blessing.
Thanksgiving Day is really a harvest festival.This is why it is celebrated in late fall,after the crops are in.But one of the first thanksgivings in America had nothing to do with a good harvest.On December 4,1619,the Pilgrims from England landed near what is now Charles City,Virginia.They knelt down and thanked God for their safe journey across the Atlantic.
The first New England Thanksgiving did celebrate a rich harvest.The Pilgrims landed at what is now Plymouth,Massachusetts,in 1620.They had a difficult time and the first winter was cruel.Many of the Pilgrims died.But the next year,they had a good harvest.So Governor Bradford declared a three-day feast(盛宴).The Pilgrims invited Indian friends to join them for their special feast.Everyone brought food.
In time,other colonies(殖民地)began to celebrate a day of thanksgiving.But it took years before there was a national Thanksgiving Day.During the Civil War,Sarah Josepha Hale persuaded Abraham Lincoln to do something about it.He declared the last Thursday of November 1863as a day of thanksgiving.Today,Americans celebrate this happy harvest festival on the fourth Thursday in November.Canadians celebrate Thanksgiving Day in much the same way as their American neighbors.But the Canadian thanks-giving Day falls on the second Monday in October.
