One day, Jack’s parents told him that his grandpa would retire (退休) after working for forty years. Jack said in surprise, “I’m only seven, so it means Grandpa has been … err… A really long time!”
His parents said, “Yes. That’s why we are going to have a surprise party for him.”
Jack loved his Grandpa and wanted to do something special for him. He remembered the business card his grandpa had given him two years before. He knew that his grandpa would no longer have the position (职位) on that card, so he decided to build a new one for his grandpa.
When the big day came, Jack was ready. But he didn’t want to put his gift together with others’. He carried it around with him the whole evening.
When all the other people left, he took his grandpa’s hand and brought him over to a chair and gave him the gift.
His grandpa smiled, “Well, it must be a beautiful gift. May I open it now?”“Sure!” Jack said excitedly.
As Grandpa opened the gift, tears came into his eyes. Jack gave him the greatest gift he had ever got! They were business cards with his new position: FULL-TIME GRANDPA! Jack said, “Now your full-time job is my grandpa!”
“Well, how much do I get paid?” his grandpa asked, smiling. “As many hugs (拥抱) as you want!” With these words, Jack gave Grandpa a hug. “Well, I guess that means I’m the richest man in the world!” said Grandpa.

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.

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!
