As is shown in the table， there have been great changes in people"s diet between 1986 and 1990. From 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. And the same goes for fruit and vegetables. On the other hand， the consumption of highnutrition food such milk and meat has increased rapidly.
What has caused these changes？ There are mainly three reasons(主题句). First， people are much wealthier than before. With higher income， they can afford to buy nutritious foods. Second， people have realized the importance of a balanced diet to their health. Lack of certain amount of meat or milk， for example， will result in poor health. Finally， owing to the economic reform， meat and milk， which were scarce in the past， are produced in large quantities.
Although milk and meat are important to one"s health， eating too much rich food may result in obesity and may other diseases. 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.
II. Direction： Study the following chart carefully and write an essay in which you should 1. describe the chart； 2. account for the fact revealed in the chart； 3. You should write about 160-200 words nearly on ANSWER SHEET 2．
The Number of scholars returning from overseas over the past years范文：
As is vividly betrayed in the chart above， the number of scholars returning from the overseas has been climbing over the past years and rocketed to over 50 thousand in the year of 2004. People may wonder what is behind the amazing figure.
The foremost reasons for the tremendous increase which is clearly revealed in the chart above can be illustrated as follows. To begin with， a set of preferential policies has contributed to the increase of the number. To attract the students studying overseas to return， our government has set up a suite of preferential policies in terms of salaries， residing place， housing， choice of jobs， and children"s education. Without the preferential policies， the increase of the number is out of the question.
What"s more， the rapid development of our motherland has led to the increase of the number of scholars returning from overseas. Since 1978， China has carried out Opening-up and Reform， which has greatly improved the growth of China"s economy. The robust economy has laid a solid foundation for the rapid development of scientific field， which makes P.R.China a most inviting country to both Chinese at home and abroad and foreigners. Therefore， without the great leap of our motherland over the past years， the increase of the scholars returning from overseas would be impossible.
In one word， our preferential policies and rapid development of our motherland are the foundation of the increase revealed in the chart above.

This bar chart describes significant changes in the ownership of houses in a big city in China. It can be seen from the chart that a very noticeable trend from 1990 to 2000 was the dramatic increase in the private ownership of houses as opposed to the huge drop in the state ownership of houses. In 1990， three out of four houses were stateowned. However， by 2000， the percentage of the ownership of private houses has soared to 80%.
The above chart reveals that the huge expansion in the private house ownership has been accompanied by a corresponding fall in the state ownership of houses in a span of a decade. (1990-2000)
As is suggested (unfolded／demonstrated／illustrated／mirrored)in the above chart， with the sharp rise in the private ownership of houses， the state ownership of houses has dramatically (substantially／alarmingly) dropped in a passage of a decade. (1990-2000)
According to the above chart， there has been a drastic growth in the private ownership of houses， while the state ownership of houses has shrunk steeply over the past decade. (1990-2000)
From the above chart， we can see distinctly that the private ownership of houses has witnessed an huge rise as distinct from (as opposed to／in contrast to／in comparison with) the drastic decrease in the state ownership of houses in a matter of a decade.(1990-2000)
