Directions: Read the following passage. Complete the diagram by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer. As we all know, all the governments in the world collect taxes(税), but what are they and what are they used for? Some people may not know about them. There are two kinds of taxes. One of the most important taxes is income-taxes which a person pays according to the amount of his income. Whatever he is, he must pay tax if income is more than a certain amount. This is called a “direct” tax, because it is paid in money directly to the government. Another tax is paid on goods. When they are brought into a country, such a tax is paid as part of the price of these goods if they are later sold in shops. We call it “indirect” tax, because it is paid indirectly through the shopkeepers. People usually complain about having to pay taxes, but they forget that the money is spent on what they need. On one hand, we need policemen and soldiers to protect us from danger. Meanwhile, we also need schools and teachers for our children. On the other hand, we need officials and workers to serve us. Above all, we need money to develop our nation. Taxes, therefore, can’t be avoided. We have no real reason to complain when we are asked to supply money to be spent for the good of ourselves and for our fellow-citizens. Title: 小题1: are necessary in our life
