英文小作文：

Aggregate demand is the total amount of goods and services that consumers are willing to buy at a given price level. It is influenced by many factors, including government policies, economic conditions, and consumer behavior. When aggregate demand increases, prices tend to rise and production expands. Conversely, when aggregate demand falls, prices tend to fall and production contracts. Understanding aggregate demand is crucial for forecasting economic trends and formulating effective policy measures.
