Money in the economy /ɪˈkɒnəmi/ n. 经济、经济制度 /ˌiːkəˈnɒmɪks/ n. 经济学 Lisa is reading an article about money in the economy. Before we read Read the title of the article. What do you think the article will explain? Read Have you ever wished everything to be free? Imagine being able to walk into your favourite shop and take whatever you want without having to pay for it. It sounds amazing, doesn’t it? But have you ever stopped to think about why everything isn’t free? Read According to economists, our society depends on trading goods and services for money. People use their time and talents to produce goods and services for the exchange of money so that our society can keep running smoothly. If everything is free, people won’t get paid for their work. Think about it: farmers grow the food. When you buy it, they get paid for their hard work. If the food is free, farmers won’t have the money to keep growing crops and then you won’t have the chance to see and value their hard work. /iˈkɒnəmɪsts/ n. 经济学家 /ˈtreɪdɪŋ/ n. 贸易 trade v. 做买卖 /ˈsɜːvɪsɪz/ n. 服务 /ˈtælənts/ n. 天赋 /ˈtælənts/ n. 天赋 /ˈsmuːðli/ adj. 顺利地、平稳地 因... 获得报酬 /væljuː/ v. 重视、诊视 Although most things aren’t free, you may still come across free things from time to time. For example, many shops offer free samples of food and other products. You can also find free events and activities in shopping centres, such as concerts, festivals and films. But are these things really free? Economists will say no! In fact, they will probably reply with a well-known saying: “There’s no such thing as a free lunch.” According to them, when something is offered for free, there is still a hidden cost even if it’s not in the form of money. Read 偶然遇见 /ˈɒfə/ v. 主动提供 /ˈsɑːmplz/ n. 样品 /ˈprɒdʌkts/ n. 产品 /ɪˈvɛnts/ n. 公开活动、比赛项目 /ˈkɒnsəts/ n. 音乐会 /rɪˈplaɪ/ v. 答复 /ˈhɪdn/ adj. 隐藏的 Read It might be exciting to imagine a world where everything is free. However, economists will tell you it is impossible to have a completely “free lunch”. Instead of trying to get everything for free, you might find it more valuable to appreciate the hard work of others and make better choices in your life. /kəmˈpliːtli/ adv. 完全地、彻底地 /ˈvæljuəbl/ adj. 宝贵的、很值钱的 /əˈpriːʃieɪt/ v. 感谢、理解、欣赏、重视 General understanding Skimming for main idea What is the writer’s answer to the question “Is there such a thing as a free lunch?” No, there isn’t. Because when something is offered for free, there is still a hidden cost even if it’s not in the form of money. General understanding What kind of article is it? It is an argumentative essay. It’s a type of writing where you present your point of view on a topic. An argumentative essay is like having a discussion with your friends about something important.

Further thinking This makes sense to me now after reading. Instead of looking for free things, it’s better to understand and appreciate the value of hard work behind every product or service we enjoy. Read again and think: If everything is free, what may happen to our society and the economy? Update my to-do list If everything is free, our society and economy would face significant challenges.
