[Q]: Article: The United States is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam." While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California. Los Angeles is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around Experts say one possible solution to the traffic problem in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car. One suggestion is to reduce the cost of riding the bus. People who usually drive their cars could save a lot of money on gas and parking costs. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car. Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of day when most people drive to work and home again. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also ,the money collected from these tolls could be used to improve the roads and public transportation system.

[Q]: Article: Myth: Skipping meals helps you lose weight fast. Truth: There's no truth in this advice. Not only will you lose weight by starving yourself, but according to Carol Ann Rinzler, this may actually cause you to gain weight. Rinzler reasons that missing a meal causes your metabolism to slow down so that you burn food more slowly. This only makes you feel hungrier and by the time you finally do reach the table you will probably eat more food. Strange as it may seem, studies show that eating several small meals and snacks throughout the day is a more healthy way to lose pounds. Myth: If you swallow gum ,it will stay inside your stomach for seven years. Truth: Actually, it takes just a few days for gum to make its exit---not seven years, says Nei Izenberg, M. D., editor of Kids Health Organization. But because gum is made of the same thing as rubber, it cannot be fully digested in your stomach--- so if you gum up the works on a regular basis, you might find yourself in a sticky situation. Myth: The best way to stop a nosebleed is to lift your head back. Truth: Now that's bad advice. Bloody noses are caused by broken blood vessels , so while lifting your head back might stop the fluid from rushing out of your nose, it won't stop the bleeding; you'll just end up swallowing lots of blood. Your best bet? "Rest quietly. Don't poke or pick, and the blood will naturally clot within a minute or two". Suggests Dr. Izenberg. Myth: Cutting your hair will make it grow long faster. Truth: That's not true. "Your hair isn't like a lawn or a rosebush, where cutting can stimulate fresh growth," says Phillip Kingsley. The length of your hair is genetically ( ) determined. When it reaches a certain length, it stops growing. When you clear up the dead split ends, this make your hair look healthier, but not necessarilylonger.
Answer: make you burning food more quickly

[Q]: Article: Amazingly, US crime figures have been falling for 20 years now. Of course, the big question is, why? And can any lessons be learnt? One reason could be the fall in the demand for the drug crack. During the 1980s, drug-related crimes soared, mostly caused by desperate crack users. However, according to professor Blumstein, co-author of The Crime Drop in America, news of the dangers of crack use caused its decrease and led to a fall in the number of drug-related crimes. Some say that the adoption of a zero-tolerance policy in many cities has helped lead to a fall in crime. In New York City, for example, mayor Rudy Giuliani imposed strict and automatic punishments for all crimes, including minor offences such as graffiti and littering. Many believe this has had a very strong deterrent effect. Another reason could be smarter policing strategies. Anti-theft measures and educating the community about car theft has helped see a drop in crimes in many areas. Also, the use of crime mapping schemes that can discover identify crime peaks in different parts of the city has helped police target hotspots. Another reason could be that more criminals are now behind bars. Sociologist John Conklin (from Tufts University) says a significant factor behind the fall in crime in the 1990s is the simple fact that many criminals are in jail. In his book Why Crime Rages Fell, he says sentencing was merciful in the 1960s and 1970s, when crime rose. But then more prisons were built and more offenders were imprisoned. Some have linked the fall in violent crime to a decline in children's exposure to lead in petrol. Jessica Wolpaw Reyes says, "Even low to moderate levels of exposure can lead to behavioral problems, reduced IQ, hyperactivity and youth crimes. You can link the decline in lead between 1975 and 1985 to a decline in violent crime 20 years later." Others say that the drop in crime has something to do with birth rates. According to statistics, birth rates peaked between 1957 and 1961, and the proportion of men in the US in their late teens and early 20s (the so-called "criminal age") was highest in the late 70s and early 80s. However, as time went on, the proportion of people in this age group decreased. Others claim that videogames have helped. A recent study has suggested that these games are keeping young people off the streets and therefore away from crime. Advocates of this argue that any effects the games may have in encouraging violent behavior is _ by the fact that the games keep potential criminals indoors and in front of the television. Some argue that the widespread use of camera phones makes some criminals think twice before committing a crime and getting filmed doing it. Also, many believe that the mass use of CCTV has also had an effect. Finally, some say that petty theft just isn't worth it any more. The resale value of second-hand goods such as televisions, cameras or clothes is now so low (or even non-existent) that most people see no point in stealing. So, what do you think?
