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 fortable 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？”

(答案→)How to spend money wisely.
解析：每个人都知道怎样花钱，但不是每个人都知道怎样花钱才明智。把每一笔消费都看做是一次投资，它们在将来会为你带来回报，这样花钱才是明智的。
【小题1】根据第一句“Everyone knows how to spend money, but not many people know how to spend it wisely.”可知，文章讲的是如何明智消费，故填How to spend money wisely.
【小题2】根据第二段“For one thing, you can consider how long the shoes are going to last. ...Besides, the pair of shoes that costs two hundred dollars will be more fortable than cheaper shoes.”可知，决定一双鞋子质量的是穿的时间和是否舒适，故填The length of lasting and the fort of wearing.
【小题3】根据第二段“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?”可知，便宜的鞋子可能穿不了很长时间，还会让脚不舒服，甚至带来疼痛，故填They may not last long and may be unfortable.
【小题4】根据第三段“You will spend more money on medical services later on in life.”可知，买垃圾食品是不明智的，因为，你不得不为垃圾食品带来的疾病医治买单，故填Because you will spend more money on medical services later.
【小题5】根据第四段“When you can treat any spending as an investment, that means you are spending money wisely.”可知，把每一笔消费都看做是一次投资，这样花钱是明智的。故填By treating any spending as an investment.
