阅读下面短文，并按照题目要求回答问题。（注意题目里词数的要求） [1] Everyone knows how to spend money, but not many people know how to spend it wisely. When you learn to spend wisely, you are learning the art of saving money. [2] Spending money wisely does not mean buying cheap goods. A pair of shoes that costs two hundred dollars is probably better than a pair of shoes that costs twenty dollars. How do you know which pair of shoes is better? For one thing, you can consider how long the shoes are going to last. If the pair of two­hundred­dollar shoes can last (for) five years，the average cost of the shoes per year is just forty dollars. Besides, the pair of shoes that costs two hundred dollars will be more comfortable than cheaper shoes. The pair of cheaper shoes may last only a few months and cause your legs to suffer. Why should you spend money buying pain and suffering? However, some shoes that last a very long time are very cheap. If you can find this kind of shoes, you are getting very good value for your money. [3] When you spend money on junk food, you are using your money to buy sickness and early death. No matter how much the cost of the meal is, spending money on junk food is foolish. You will spend more money on medical services later on in life. Investing (投资) in your health means you can save money on medical costs. Many people, who live more than a hundred years old, live happily in the pink. They seldom suffer from serious illnesses. They are the ones who invest in their health and save money on medical costs. [4] When you can treat any spending as an investment, that means you are spending money wisely. It will produce returns for you in the future. Whenever you need to buy something, please ask the question, “Is this an investment or just spending？” 小题1:What's mainly talked about in the text?
