Cutting television time to less than two hours a day can add one point four years to life. The human body is designed to move. The fact is just the opposite.

Sitting is something we do all the time. On average, Americans sit for four and a half to five hours a day. But that does not make sitting good for us.

Even if you exercise for 30 minutes a day, what goes on in the other 23 and a half hours a day is also very important. Changes are coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk". It is an exercise machine that lets you walk slowly in one place. Even some U.S. schools begin to experiment with desks that are part bicycle to keep children moving. Many companies may not buy a standing desk for everybody. However, they may get five standing desks or a treadmill desk for their employees and put them in a certain place where people can go for an hour a day to answer their emails or talk on the phone. Experts suggest some other activities: take a walk at lunchtime; walk to the offices and talk directly instead of emailing colleagues. All these activities may help you live longer. Question: Why should people stand up according to the new research? - They should touch their toes. - Standing more can cure some diseases. - Sitting less does people good and may help people live longer. - They spend too much time watching TV.

Read the following article and select the best answer. Article: The work of railroad pioneers in America became the basis for a great surge of railroad building halfway though the nineteenth century that linked the nation together as never before. Railroads eventually became the nation's number one transportation system, and remained so until the construction of the interstate highway system halfway through the twentieth century. They were of great importance stimulating economic expansion,but their influence reached beyond the economy and was strong in American society at large. By 1804, English as American inventors had experimented with steam engines for moving land vehicles. In 1820,John Stevens ran a locomotive and cars around in a circular track on his New Jersey estate,which the public saw as amusing toy. And in 1825, after opening a short length of track, the Stockton to Darlington Railroad in England became the first line to carry general traffic. American businesspeople, especially those in the Atlanic coastal region who looked for better communication with the West, quickly became interested in the English experiment. The first company in America to begin actual operations was the Baltimore and Ohio,wich opened a thirteen-mile length of track in 1830. It used a team of horses to pull a trainof passenger carriages and freight wagons along the track. Steam locomotive power didn't come into regular service until two years later. However, for the first decade or more, there was not yet a true railroad system. Even the longest of the lines was ly short in the 1830's, and most of them served simply to connect water routes to each other, not to link one railroad to another. Even when two lines did connect, the tracks often differed in width, so cars from one line couldn't fit onto tracks of the next line. Schedules were unreliable and wrecks were frequent. Significantly, however, some important developments during the 1830's and 1840's included the introduction of heavier iron rails, more flexible and powerful locomotives, and passenger cars were redesigned to...

Read the following article and select the best answer. Article: Dear Michelle, My mother is not a good example for me and my sister. She smokes, stays out late, and she curses. I love her but I am ashamed of her. I do not want to bring home my friends because she does not act like any of the other mothers. She says I am a loser because I sit at home and I study. I wish I could live in another family that is normal, but that will not be for another 5 years when I am 18 and legal. What am I supposed to do until then? Prisoner of a Crazy House Dear 7th Grade, I am glad that you love your mother because the rest of your feelings about her may change as you mature and get older. While it is true that your mother's smoking, partying and cursing bring you shame, the fact that you want to stay separate from her doing is notable and very smart. It shows that you are a winner, not a loser. I am guessing, therefore, that you do not bring shame to yourself, and that is a good thing. So, keep it that way and keep away from your mother's habits. In the meantime, get the best grades as possible and join clubs and after-school activities. Offer social service on weekends and visit with your friends at their homes. Unfortunately, you are not alone. Many teens live in homes with immature, misguided, selfish parents. Those kids often feel lonely and separate from the rest of their friends because of their parents' terrible deeds. Yet, despite this, some of these very teens grow up to be just fine. They develop good friendships with nice kids, do well in school, and often find a teacher of guidance advisor who makes all the difference! Do it, Miss Winning 13-year-old, and keep looking forward to your own fine future. Maybe by then your mother may even see the light and realize how surprising you really are. Best luck!
