A、happy life and a meaningful life are not the same. Leading a happy life is associated with being a “taker”, while leading a meaningful life corresponding with being a “giver”. Happiness is about feeling good and getting what we want. People who are happy tend to think that life is easy. They are in good physical health and able to buy the things that they need often associated with selfish behavior.Animals have needs and desires and they can feel happy too. What sets human beings apart from animals is not the pursuit of happiness, but the pursuit of meaning, which is unique to humans. We can often find meaning in helping others or making a sacrifice(牺牲) for a “greater good”. Meaning often comes at the expense of happiness. When people have invested themselves in something bigger than themselves, they worry more and higher levels of stress and anxiety in their lives than happy people. Volunteering(做义工) in rural schools, for example, is meaningful but also involves hardship. Happiness, like any emotion, is felt in the here and now--it eventually fades away. However, meaning is enduring. It connects the past to the future. From Paragraph 3 we know that_____. A、helping others can make our life meaningful B.meaning comes together with happiness C.happy people have higher levels of anxiety D.volunteering in rural schools makes a happy life
