Question: Article: Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs , teachers find students' posture and attention improve. Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning. The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico and Japan," says Witt, " Research shows that sitting on the balls makes them sit up straighter . You can slouch on a ball," says Witt, "but it feels bad." Because the students are moving, their blood increases. That carries more oxygen( ) to the brain , so the kids have more energy and can pay attention longer. "Besides, they're fun." says Pownall.

Question: Article: New Orleans, Louisiana, was established as part of the French Empire in 1718. Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France, and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it, and the Americans under General Andrew Jackson. The riverbed of the Mississippi is constantly silting and the river is now actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river. Although New Orleans has been a part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which, for many years, was its only law. New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The Jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting surface of yesteryear is a busy industrial and port city. Grain and coal come from the Midwest and foreign goods are unloaded here. New Orleans is no longer a sleepy Southern town----but it's still fun to visit.

Question: Article: People express their personalities in their clothes, their cars, and their homes. Our diets can also show our personalities because we might choose certain food to tell people something about us. For example, some people mainly enjoy high quality food, such as caviar and lobster , and they eat only in expensive restaurants - never in cafeterias or bars. They know about the "better things in life". Some people choose not to eat meat. Vegetarians often have more in common than just their diet. Their personalities might be similar too. For instance, vegetarians in the United States and Canada may be creative people, and they might not enjoy competitive sports or jobs. They worry about the health of the world, and they are probably strongly against the war. Some people eat mostly fast food. One study shows that many fast-food eaters have a lot in common, but they are very different from vegetarians. They are competitive and good at business. They are also usually in a hurry. Many fast-food eaters might not agree with this description of their personalities, but it is a common picture of them. Some people also believe that people of the same astrological sign have similar food personalities. Aries (born under the sign of Aries, between March 21 and April 20) usually like spicy foods, with a lot of onions and pepper. People with the sign of Taurus (April 21 to May 22) prefer healthful fruits and vegetables, but they often eat too much. Sagittarius (November 22 to December.22) like traditional food from many different countries. What is your food personality?
