　　Our bodies also use energy．Do you want to know how much energy you use every day? A special machine at the exhibition can tell you．Type in some information about your weight, height, age and job．Then the machine gives you your answer．According to the exhibition, a person usually uses 9.3 liters(升)of oil worth of energy a day．

　　Visitors can also learn about some advanced technologies(高科技)for getting energy．For example, they can use some technology for exploring the deep sea and finding oil．
