Radio host: Good evening, this is Star Talk. Today we invite our old friend Susan to share her story.

Susan: Good evening. Today I’d like to talk about a girl—Stella Green. She inspired (鼓舞) me most.

I organize camps and teach climbing in the camps. One morning at Dynamo Camp we were watching a video about climbing when Stella Green came. She opened the camp door sitting on a wheelchair (轮椅) and told me she wanted to go climbing. We didn’t understand why such a disabled girl came here. In fact her left leg was just hurt when she climbed mountains but she loved climbing.

At first, I was afraid Stella would feel sad. But she was so sure about what she was doing. I moved the wheelchair closer to the wall. When Stella stood up, she took the first climbing hold and began to put her feet on the other holds. I soon knew that those legs didn’t need me. They could finish the climbing themselves. And move after move, Stella made me surprised and cry. When reaching the top, she cried out happily.

From this experience, I know Stella and I have a great lesson—never give up, trust yourself and do all you can.

That’s all. Thank you.

Snacks are many people’s favorites, especially children and young women. Nowadays, more and more young people like to have snacks during the middle of the night. But a recent study shows that midnight snacks could bring some health problems. Namni Goel, lead scientist of the study, said “Midnight snacks will break your normal life habits. They will make you put on weight easily and make you get heart disease easily. Also they will greatly influence your feelings.”

This isn’t the first time a study has shown that midnight snacks could be bad for your health. The following four main problems were shown according to the common studies. It may surprise you a lot, but you should really make a right decision now. It will make a difference to your future life.

First, midnight snacks can influence your memory. The study found that midnight snacks are even bad for your cognitive functions (认知功能). Second, they can make you have weird dreams. The sugar in midnight snacks will excite your brain at night and make you feel nervous. Then you will probably have dreams which are not usual in your life. Third, midnight snacks make you get heart disease easily. Scientists have found that midnight snacks could make you have high blood pressure. As a result, you will have heart problems. Finally, midnight snacks can make you feel hungrier than usual when you wake up the next morning. So it’s high time that the young thought about their eating habit more. After all, having good health is what everyone wants most.

Most young people want to travel abroad (国外), but they don’t have enough money.

Volunteering abroad program!     16     It’s interesting and unusual, and it may be something you never thought of before.

Each summer, there are hundreds of volunteer work projects (项目) all over Europe and the United States. These projects give young travelers an exciting chance (机会) to spend two or four weeks. Volunteers usually work about 40 hours a week.     17     volunteers often live in a school or a church (教堂) and cook their own meals together.

    18     You have the chance to experience the life there when doing the volunteering work abroad. You can learn more about the culture and develop a real understanding of the culture. You can practice language and improve life skills. Also, you can meet people all over the world.     19    

Jimmy, a volunteer, said, “My working experience abroad was fantastic.     20     The work was difficult, but I enjoyed myself in it. I will never forget the meaningful experience.”
