听力原文： We use all sort of services without thinking how we get them. But such services cost money. We pay them through taxes. What would happen if everyone in a city stopped paying taxes？ The street might not be cleaned. There would be no police force to protect people and property. The chief duty of every government is to protect people and property. More than three-fourths of the money spent by our government is used for this purpose. The next largest amount of public money goes to teach and train our citizens. Billions of dollars each year are spent on schools and libraries. Public money is used to pay the teachers and other public officials. Years ago the government made money from the sale of public lands. But most of the best public lands has now been sold. The money raised was used to help pay the cost of government. There are still some public lands that contain oil, coal, gas, and other natural resources. They could be sold, but we want to save them for future years. So we all must pay our share for the services that make our lives comfortable.
