Primary school children in the UK have little choice over what they eat for lunch. Either their parents pack their lunchbox, or they choose from only one or two options（选择，选项）on a hot dinner menu. However, secondary schools let students make their own meal choices freely.

In the past, this has led to problems. There is a 2004 survey called School Meals in Secondary Schools in England. It showed that many schools offered unhealthy menus. For example, on four or five days of the week, 76 percent of schools served chips and other potatoes cooked in oil, while 86 percent served high fat meals like burgers and fried chicken. And when offered such dishes, most students were picking them：48 percent chose high fat main dishes; 48 percent chose chips or similar and 24 percent chose cakes or muffins（松饼）. Fruit, fruit juice, vegetables and salads were the least popular choices.

In his 2005 television series Jamie’s School Diners, famous chef Jamie Oliver began working with school cooks on providing more healthy meals. At first, many students and parents were against the idea. But the tide began to turn and Jamie’s effort has led to a general improvement in nutritional standards（营养标准）for school meals.

More recently, online systems like “Parent Pay” give parents more control over what their children are eating at school. They can set daily spending limits and see exactly what their kids are buying each day.

Long long ago, there was a young man who made his living by making tofu. One day, the tofu was not sold out. In order to keep the tofu fresh, he cut the tofu into pieces and mixed some flavor (香料) in. Then he put it into a crock (瓦罐). A few days later, he opened the crock and found that the smell was terrible. Then he tasted a piece. To his surprise, the taste was nice. An idea came into his mind-maybe his smelly tofu (臭豆腐) would be a kind of special food. As expected, the smelly tofu became popular with local people. Soon it was well-known all over the whole nation.

Now smelly tofu is the most special food in Hunan. And it is recommended (推荐) to all the people around the world.
