Task：Three graphs show the annual expenditure of university students in three countries in 2003.
参考范文：
The three pie charts show how university students in three countries spent their money in the year 2003.
In general, students in country A spent slightly more than those in country B (US$ 5,000 and US$ 4,500 respectively). In comparison, student expenditure in country C was considerably lower, at only US$ 1,500 per year.
Accommodation and food were the two biggest items of expenditure. Altogether they constituted around 60% of the total students’ expenditure in all three countries. The difference is that in country A and B accommodation spending exceeded food spending while the reverse was true for country C.
The rest of the students’ spending was divided among leisure, book and “others”. Leisure spending constituted a larger percentage (around 20%) of student expenditure in both country A and B, while in country C more money was spent on book (21%) than on leisure (12%).
Overall, as wealth decreased, the percentage of students’ spending on nonessential items went down.
