Changes in People's Diet
As can be seen from the table, great changes have been taking place in people's diet in the past five years. Grain, as the main food of most Chinese, is now playing a less important role, while the proportion of some high-energy foods, such as milk and meat, has increased.
What has caused these changes? I think there are two reasons. First, people now have more money. The price of meat and milk is much higher than that of grain, so in the old days people couldn't afford them. Now they have enough money to buy both meat and milk. Second, people nowadys pay more attention to the elements of their diet. They look for a well-balanced diet that will be good for their health.
In short, there have been changes in people's diet in the past five years because of financial and health reasons, and there will be further changes in the future.
教材16页：Population of a Small Island State
饼状图：
Population of a Small Island State
Directions: Write a composition based on the following graph. The composition should be entitled "Population of a Small Island State."
From the diagram, we can see that between 1900 and 1950, the population of the state remained a little less than 200,000. Since 1951 it has been increasing rapidly. In the past four decades, the population has gone up by over three times.
There are several reasons for the increase. Firstly, the open policy being carried out in the state has enabled many foreign labourers to work there. Secondly, the beautiful scenery of the small island has attracted many tourists and some of them have been permitted to settle there. In addition, the government may not have realized the necessity of controlling population.
If this trend continues, it is no doubt that the small state will suffer from various kinds of problems caused by overpopultion, such as lack of land resources, food shortage and traffic congestion. Therefore, actions should be taken to control the increase of the population.

Spending Summer Vacation

(1) state the changes briefly
(2) give possible reasons for the changes
(3) predict the trend of changes
College Students' Ways of Spending Summer Vacation
A. staying at home
B. traveling
C. doing social investigation
D. other ways
From the two charts, we can see that in the past ten years the number of students who go travelling or do social investigation during summer vacation has increased greatly while that of those who stay at home has decreased a lot.
There are several reasons for the changes. Firstly, with the development of economy, many people have become rich. Students can get financial support from their parents for travelling. Secondly, tourism has greatly developed over the past ten years. Many new scenic spots have been built. In addition, the open policy has brought in from some other countries some harmful ideas on politics and thus aroused among college students some false opinions about China, so the government has been encouraging college students to do investigations on the rapid development in both urban and rural areas.
From the changes in the charts, we can predict that more and more college students will make their summer vacation interesting and meaningful by going to the outside world instead of staying at home.
