四、案例分析

以下是一篇雅思写作7分的范文：

Task 1：Line Graph

The line graph illustrates the percentage of students who attend three different types of schools in a city over a period of 20 years. The graph shows that the number of students attending private schools increased significantly from 15% in 1980 to 35% in 2000. During the same period, the number of students attending state schools decreased from 70% to 50%, while the number of students attending religious schools remained stable at 15%.

The reasons for these changes can be attributed to several factors. Firstly, the rise in the number of students attending private schools can be attributed to the increasing wealth of families in the city. As more families can afford to pay for private education, the demand for private schools has increased. Secondly, the decline in the number of students attending state schools can be attributed to the decreasing quality of education in these schools. Many parents believe that private schools offer a better education for their children. Lastly, the stability of the number of students attending religious schools can be attributed to the religious beliefs of the families in the city.

In conclusion, the line graph clearly shows that the percentage of students attending private schools has increased significantly over the past 20 years, while the number of students attending state schools has decreased. This trend is likely to continue in the future.
