【简答题】
If you have no special plans for your holidays, why not spend your time helping others?Don’t believe those people who say that young people today often think only of themselves. It’s not true at all. More and more young people in the USA volunteer to spend their school holidays working for others. And they don’t do it for money. Here are some of their stories. Alice, 17 I’m going to help the Forest Center build new hiking paths in the mountains. It’s going to be great fun — I’ll spend the whole summer living in a forest and breathing the clean mountain air. I’m going to sleep under the moon and stars. It will be a nice sport, and I’ll be able to do something good at the same time! Jason , 18 This summer, I’m going to volunteer with Special House Program. They build good, less expensive houses and sell them to families that are not very rich. They’ll teach me what to do, so I’ll help people and also have a chance to learn how to build houses. Trish , 16 I’m going to teach children who have trouble in reading. I’ll work for a program called Reading for Life. Every day, I’m going to help them choose and read books that they like. I want to be a teacher, and I love children and reading, so this is going to be a great experience for me. 小题1:What does Alice plan to work for others in summer? A.To sleep under the moon and stars.
