Chinese cuisine（菜肴）is widely known and enjoyed in the world. But there is one interesting concept concerning Chinese food which is almost unheard of in the West, and which is becoming increasingly ignored by the youth of the East - the ancient custom of “tonic food.”
Tonic food is food which is consumed to improve one’s well-being, or stave off sickness, particularly at times when one is more likely to fall ill. For instance, it was once the custom for new mothers to eat a sesame-oil hot pot every day for the first month after giving birth. It was believed that this dish would benefit the muscles, reduce pain, improve circulation, stimulate sweating, and warm the body.
In fact, some Western theories of health are similar to the beliefs in Chinese tonic food, although each takes a different path toward the very same goal. Western medicine actually recommends some of the exact same ingredients that make up tonic foods. Sesame oil can provide lots of calories, and chicken meat is particularly high in protein. Any Western doctor should be happy to suggest such a Chinese dish after childbirth.
The elderly, weak, and young can also benefit greatly from tonic foods, especially during the winter. Some foods, such as goat meat and spinach, are seen as “hot,” while others, such as Chinese cabbage and radish, are seen as “cold.” One should be careful not to eat too much of either “hot” or “cold” food. However, how much “hot” or “cold” food one should eat depends on the time of the year, how the food is prepared and what it is prepared with, and the individual’s health.
“Warm” or “cool” tonic foods are strongly recommended. The choices for “warm” and “cool” foods range from simple sea cucumber to the delicacy of bird’s nest soup, depending on the individual’s economic circumstances.
The concept of tonic food is far from losing credibility, either with Westerners or practitioners of modern medicine. For example, up until two years ago, tonic foods were added to the meals served at a renowned hospital.

American public education has changed in recent years. One change is that increasing numbers of American parents and teachers are starting independent public schools called charter schools.
In 1991, there were no charter schools in the Unite States. Today, more than 2300 charter schools operate in 34 states and the District of Columbia. 575000 students attend these schools. The students are from 5 years of age through 18 or older.
A charter school is created by groups of parents, teachers and community members. It is similar in some ways to a traditional public school. It receives tax money to operate a number of students. The charter school must prove to local or state governments that its students are learning. These governments provide the school with the agreement, or charter that permits it to operate.
Unlike a traditional public school, however, the charter school does not have to obey most laws governing public schools. Local, state or federal governments cannot tell it what to teach.
Each school can choose its own goals and decide the ways it wants to reach those goals. Class sizes are usually smaller than in many traditional public schools. Many students and parents say teachers in charter schools can be more creative.
However, state education agencies, local education-governing committees and unions often oppose charter schools. They say these schools may receive money badly needed by traditional public schools. Experts say some charter schools are doing well while others are struggling.
Congress provided 200 million dollars for establishing charter schools in the 2006 federal budget. But, often the schools say they lack enough money for programs. Many also lack needed space. District officials say they have provided 14 former school buildings for charter education. Yet charter school supporters say officials should try harder to find more space.

Japan's 24-hour convenience stores, already struggling with lagging sales and growth, may soon face yet another threat - moves to limit business hours and close the stores late at night. The district of Saitama, which borders Tokyo, may follow in the footsteps of the western city of Kyoto and urge convenience stores to close during late night hours in an effort to limit carbon dioxide（二氧化碳）emissions, Japanese media reported.
Kyoto, a former capital, wants to persuade convenience and other 24-hour stores to close late at night so as to improve evening views of the city and cut down on energy use. The Nikkei business daily said closures could last from 11 p.m. to 7 a.m. The move is strongly opposed by the industry, which fears a bad impact on an already troubled sector also grappling with the specter of a higher tobacco tax, which could hit overall sales.
"Even if we only operate the stores for 16 hours, we can't stop the refrigerators," said Toshiro Yamaguchi, the president of Seven-Eleven Japan Co, which is owned by Seven & I Holdings Co Ltd, at a news conference in Saitama on Tuesday. He said such cuts in operating hours would reduce each store's profit by 20 percent. "If this happens, our current business model will lose its foundation."
Analysts said that while it is difficult to estimate the potential impact of the move without a concrete plan, their overall impression was that it was likely to be negative. "This could cut profits and lead to less efficient operations and the increased loss of opportunities," said Masafumi Shoda, an analyst at Nomura Securities. "But it depends on the store -- urban stores do better than others. There are some in the countryside that are inefficient."
Some have suggested that if governments were sincere about reducing carbon emissions there were much more efficient methods, such as cutting back on the huge number of automatic vending machines（自动售货机）
