练习1：Directions: For this part, you are allowed thirty minutes to write a composition of no less than 120 words on Changes in People’s Diet. Study the following table carefully and your composition must be based on the information given in the table. Write three paragraphs to:
1. state the changes in people’s diet (饮食) in the past five years;
2. give possible reasons for the changes;
3. draw your own conclusions.
You should quote as few figures as possible.
⑴As is shown in the table, there have been great changes in people's diet between 1986 and 1990. ⑵From the table, we can find that grain, formerly the main food of most Chinese people, is now playing a less important role in people's diet. ⑶And the same goes for fruit and vegetables. ⑷On the other hand, the consumption of high-nutrition food such milk and meat has increased rapidly.
⑸What has caused these changes? There are mainly three reasons (主题句). (6) First, people are much wealthier than before. (7) With higher income, they can afford to buy nutritious foods.
(8) Second, people have realized the importance of a balanced diet to their health. (9) Lack of certain amount of meat or milk, for example, will result in poor health. (10) Finally, owing to the economic reform, meat and milk, which were scarce in the past, are produced in large quantities.
(11) Although milk and meat are important to one's health, eating too much rich food may result in obesity and may other diseases. (12)Therefore, people should not only eat a lot of milk and meat, but also enough grain, fruit and vegetable for the sake of their health.
