The pie charts demonstrate the changes in annual expenditure of five
categories, namely Insurance, Teachers’ salaries, Furniture and equipment,
Resources (e.g. books) and Other workers’ salaries by a certain UK school
in 1981, 1991 and 2001.
Overall, Teachers’ salaries represented the prime part of all spending. In
addition, Insurance and Other workers’ salaries underwent a consistent
trend (upward and downward respectively) while the others fluctuated
Teachers’ salaries accounted for 40% or higher, with 40% in 1981, 50% in
1991 and 45% in 2001. Insurance experienced a significant rise, with the
figure of 2001 was fourfold that of 1981 (8% in comparison to 2%). In
contrast, Other workers’ salaries encountered a plummet, with the figure of
2001 was just over a half of that of 1981 (15% in comparison to 28%).
Regarding Furniture and equipment, before reaching 23% in 2001, it
decreased dramatically to 5% from initial point (15%). As far as Resources
(e.g. books) is concerned, it climbed from 15% to 20%, then fell sharly to
approximately a half, with 9%.
P/S: could you share with me some more other words/ phrases to describe a
trend which occurred in the past. I just know some words such as
experienced, underwent (encountered: I am not sure)?
