生命中最美好的事物都是免費的，次美好的事物都很貴。
2、作文（供參考）
The life consumption level of people is increasing year by year. Maybe it takes you a year to save up for a new car. You perhaps use one third of your salary to buy a bracelet. Pursuiting of luxury seems like a trend nowadays because luxury is a symbol of fashion, wealth and even status.
However, do you find that the best things in life are free? They are families, friends, hugs, smiles, sleep and so on. I felt very comfortable when I saw this picture. When your life is tough, you are still rich because all of these free things belong to you. As a result, you are not broke forever even though there are only several cents in your pocket.
