What two things did Kang Jian want to buy in America? Where were they made?The Difficult Search for American Goods in the US If you go to another country, what kinds of things would you buy? Would you buy a camera in Japan, some beautiful clothes in France, or a watch in Switzerland? No matter what you maybuy, you might think those products were made in those countries. However, you could be wrong. Kang Jian is a 17-year-old student from Shanghai. Last year he went to visit his aunt and uncle in San Francisco. He found it interesting that so many products in the local shops were made in China. “I wanted to buy a toy car for my cousin, but even though most of the toys were American brands, they were made in China.” Toys are not the only things made in China. “I wanted to buy a pair of basketball shoes,” he explains. “But I had to visit five or six stores before finding a pair made in America!” He realized that Americans can hardly avoid buying products made in China. “In fact,” he continues, “there were many other things there made in China footballs, handbags, pet food, mobile phones. Even American flags are madein China!” Kang Jian thinks its great that China is so good at making these everyday things. However, he wishes that in the future China will also get better at making high-technology products that people can buy in all parts of the world.1.

MOVING FROM GENERAL TO SPECIFICA general introduction of the topic is usually followed by specific details and examples.Beauty in Common Things Each different part of China has its own special forms of traditional art. These usually try to show the things that are important in life, such as love, beauty and family. The most common things, from paper to clay to bamboo, are turned into objects of beauty. According to Chinese history, sky lanterns were first used by Zhuge Kongming. He sent them out to ask for help when in trouble.Today, sky lanterns are used at festivals and other celebrations. They are made of bamboo and covered with paper. When the lanterns are lit, they slowly rise into the air like small hot-air balloons for all to see. They are seen as bright symbols of happiness and good wishes. Paper cutting has been around for over 1,500 years. Paper cutting sounds very easy but it can be difficult to do. The paper, usually red, is folded before it is cut with scissors. The most common pictures are flowers, animals,and things about Chinese history. During thespring festival, they are put on windows, doorsand walls as symbols of wishes for good luck and a happy new year.Chinese clay art is famous because the clay pieces are so small but they look very real. The pieces are usually cute children or lively characters from a Chinese fairy tale or historical story. The pieces are carefully shaped by hand from a very special kind ofclay and then allowed to air-dry. After drying, they are fired at a very high heat. They are then polished and painted. It takes several weeks to complete everything. These small pieces of clay art show the love that all Chinese people have for life and beauty.Traditional art form Materials used1. 2. 3. sky lanternsbamboo, paperpaper cuttingpaperChinese clay artclay 1.
