四、閱讀測驗          Sometimes you may hear that someone did a random act of kindness, which means doing something kind or thoughtful for someone that you may not even know. But do you know why he or she wanted to do that? One likely reason may be to make both the giver and recipient (接受者) happy.          Random acts of kindness are not just abstract (抽象的) ideas. They can be done easily in our daily lives. For example, you can help an old man safely cross a busy street, open the door for another person, or simply smile at someone who looks sad.          In a world where we often learn bad news in the newspapers or on TV, random acts of kindness play an important part in individuals (個人) and society (社會). For individuals, it helps the recipient have a positive view on life by knowing there is good in the world. In addition, carrying out a kind act will make the giver happy as well as the recipient. Through random acts of kindness, warmth and kindness can spread through society and make our world better.        Next time you see someone who looks sad or needs help, try to do something nice to make him or her feel better. You’ll be glad when he or she gives you a smile.
