Do you know what the White House is? Perhaps some of you do，while others don't.

    The White House is a house in Washington. The president of the U.S.A. lives in it. It's really white. But do you know why the White House is white? The story happened in 1812. That year England was at war with America. The British army got to Washington and set the president's house on fire. In 1814，in order to hide the marks of the fire，the stone walls of the president's house were painted white and it has been the “White House” ever since.

    In Europe, small cars have always been more popular than large cars. In the United States, large cars and midsize cars are more popular than smaller cars. As a result, European automakers used to make different kinds of small cars while American automakers used to build bigger, heavier cars. However, these days, automakers in both America and Europe produce cars of different sizes. This is because most automakers export their cars all over the world.

    The price of gasoline (汽油)is one reason for differences in car choices. Since gasoline is more expensive in Europe, many Europeans want smaller, lighter cars that will travel a long way on a gallon（加仑）of gasoline.

    Other reasons also enter into the big or little car decision. Many European cities have narrow, winding（弯曲的） streets. In these cities a small car is easier to control than a large one.

    For a long time, few Americans bought small cars. Instead they chose large cars, because these roomy cars were more comfortable for large families and long trips. Some people also liked the powerful engines（发动机） that large cars had. Since gasoline was cheap, drivers did not mind that the large cars used a lot of gasoline.

    But in the 1970s, there were gasoline shortages in the United States. The price of gasoline went up. Though large cars were still more popular than smaller cars, sales of small cars increased. Some people also bought small cars because these cars caused less air pollution than larger cars.

    Today, Americans' car preferences are still changing. Though Americans are still buying many small cars, the fastest growing sales are for certain kinds of large cars. These types of cars are called minivans and sport utility vehicles(SUV). They are very popular today. But of course, that could change tomorrow.

    English is becoming more and more popular in China. It can be used in every field, such as on some signs and restaurant menus. But there are some problems when people use it. Perhaps you've seen the English letters "WC" in your city. They show public toilets. But do you know it is far from native(地道的) English？In fact, foreigners from English﹣speaking countries seldom use the letters.

    Workers in our city are changing "WC" signs all over the city. The government is spending much money changing all the bad English on signs and restaurant menus. Many other places in China are following our steps.

    "WC, or water closet, is old﹣fashioned English. It sounds dirty to me. "says Nancy, a young woman from the US. The old sign will become "Gents/Men" and "Ladies/Women". "I see much poor English in everyday life, and not only on signs, "she says, "I know what they mean, but they are Chinglish, not real English. For example, when someone says to me "My hometown is Guizhou Province", I know he or she should say "My hometown is in Guizhou Province". Hometown is a smaller place in a province. The common mistakes that Nancy picked up include "Not Entry", which should be "No Entry", "Direction of Airport" should be changed to "To the Airport". And it is "Room Rate", not "Room Price". And remember to "Keep off the Grass" rather than "Care of the Green".

    The next time you walk on the street or eat in the restaurant, you can go and see if the expressions are right.

    A well—known poem by the Tang Dynasty's poet Du Mu tells a sad scene in early April, Rain falls heavily as Qingming comes, and passersby with low spirits go."

    This scene takes place on Tomb Sweeping Day, also known as the Qingming Festival. Tomb Sweeping Day is a traditional Chinese festival. It began in the Zhou Dynasty, over 2,500 years ago Chinese people celebrate it to remember and honor their ancestors(祖先). This year, it falls on April 4. Tomb Sweeping Day became a public holiday on the Chinese mainland in 2008. People have one day off for that day.

    On this day, families bring flowers, food and wine to the gravesites(墓地) of their ancestors. They place cakes, fruit in front of the graves and some may burn joss paper, as money for the dead. After that, they sweep the tombs and cherish(怀念) the memories of their dead family members

Tomb Sweeping Day gives us a chance to show respect to our ancestors and family members who have passed away and show that we miss them. This tradition shows that family values are an important part of Chinese culture.

    Tomb Sweeping Day is also the beginning of the time for gardening and outdoor active China. Families often get together for outings or to fly kites.
