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．

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．

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．
