::原文::
　　Some people eat to live, but there are others who live to eat. To live a long and
healthy life, we must learn to have a balanced diet. A balanced diet simply means a bit
of everything. A diet which includes meat, fish, vegetables and fruit is, of course,
ideal. If you watch your diet, then you won't have to suffer the pain of going on a diet.
