Passage One
We know that we have to pay for what we get. If we buy food, we know there will be a bill to pay. These are private bills. But there are also public bills that must be paid. Public bills are paid for by the government. In turn, we get these services through taxes. What would happen if everyone in the city stopped paying taxes? The water supply would stop. Water might even become unclean and impure. The streets might not be cleaned. [26]There would be no police force to protect people and property. Schools would be closed. People would become sick and diseases might spread. We should not want to live in such a city. We all want pure water and food, clean streets and good schools. We want police to prevent us from crime. The chief duty for every government is to protect persons and property. More than three quarters of the money spent by our government is used for this purpose. [27]The next large 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 all the public officials. Also, a large amount of public funds is spent on roads.
The greatest part of the needed funds is raised by taxes. A tax is money that we all must pay to support the government. [28]The law orders us to pay taxes. We have no choice in the matter. Almost everyone pays some taxes in one form or another.

答案解析：
26. According to the speaker, what will happen if the citizens stop paying taxes?
[C]解析：文中叙述了一系列市民不纳税的后果，其中就有提到“没有警察保护人民安全和财产”。故C为正确答案。A、B两项跟原文表述相反；D项与问题没有直接因果关联。
27. In what way is the next large amount of public money used?
[D]解析：原文说第二大项公款 是用来教育和培训市民。故D正确。符合“听到什么选什么”原则。A、B、C项都是利用原文中的schools，roads，police等制造的干扰项。
28. What message does the speaker want to convey in this talk?
[C]解析：全文都提到了taxes一词，且详细分析了纳税的重要性和这些税款如何取之于民用之于民，文章末尾还提到了“法律规定我们要纳税，我们别无选择”。故C为最佳选项。
