[参考作文]
As can be seen in the table, there have been great changes in people's diet in the past five years. Grain used to be the Chinese main food, but now it is playing a less important role in people's diet, while the consumption of some high energy foods, such as milk and meat, has increased steadily.
What caused these changes? The changes in diet can be accounted for by a number of factors. I think the reasons are as follows: First, the open policy brings the people opportunities to earn a lot of money. People are much wealthier than before. With a higher income, they can afford to buy food that they want to eat. Second, people nowadays pay more attention to the structure of their diet. They are seeking the most reasonable diet structure, which will do good to their health. Finally, owing to the economic reform, meat and milk, which were scare in the past, are produced in large quantities.
To sum up, with the development of the country, the level of the Chinese people's life has changed in the past five years. I'm sure there will be greater changes in the future.
