    Today is July 5, my birthday, the first day of our trip. It's 2:30 p. m. I'm riding a bike with my parents and my little brother Bob in Beihai Park. We are singing, listening to birds, and having a lot of fun.

    Today is July 6. It's the second day of our trip. We plan to visit the Great Wall. There area lot of people along the way. I feel a little tired, but I'm happy! While we are climbing the mountain, I talk about my future (将来的) job with my parents. What do I want to be? Ha! Maybe a teacher or a singer.

    My parents are visiting their old friend, a famous writer, at her place. I am having lunch with Bob and watching a show in Deyunshe. The food isn't so delicious but the show ... Well, it's so humorous and interesting. I really like it.

    It is the fourth day of our trip. We're going back home at 6:00 p. m. It's 10:00 a m. now. We are visiting the famous Chocolate Factory and making chocolate by ourselves happily. We are really having a great time here! Sweet Kiwi! I love you!

Her name is Maria Smith. She is from England. She is thirteen years old. Maria and I are new students at No. 2 Middle School. We like our Chinese class.

    It was a sunny morning. A poor(贫穷的) young man with1 right hand came to Mrs. Brown's door. He asked her for some2.

Mrs. Brown3, "You see, young man. There are some bricks(砖头) behind my house. If you help me4 them to the front, I'll pay you twenty dollars."

    "Can't you see that I lost my right hand?5 can I do it?" The old lady smiled, put one of her hands behind her body6 then picked up one brick with7. Seeing this, the young man didn't say a word and started to work right away.

    After he did the work, the young man8 with the money from Mrs. Brown and he looked a little different.

    Two years later, the young man came again with some gifts. "Thank you for9 that day. I know you didn't need me to do the work. You just wanted to make me feel better. I learnt that I could make money by working hard, too. And now I have a pancake store and a beautiful wife."

    How would you use a radio or a telephone ifyou had no electricity or batteries? These1bothered (使烦恼) British inventor Trevor Baylis. So in 1996 he2awind-up (装有发条的) radio. It doesn't need electricity orbatteries. You wind it up3hand. It plays for about an hour. Then,you wind it up4.

    Baylis also invented a mobile phone that ispowered by5. The shoes contain (含有) a small battery that is powered when you6.This battery is connected to a mobile phone. These two simple inventions canbring modern7to all parts of the world.

    Baylis didn't have a university degree inengineering. In8, he left high school before graduating(毕业). He just loved9thingsto help people. He never knew10ideas would come to him.The idea for the phone came to him in a dream.

The 24-year-old volunteer, who is known online as Danni recorded(记录) happy times with her students on her phone. Each of the videos attracts thousands of Chinese netizens who are interested in her volunteer experiences.

After finishing university in 2020, Danni chose to work in Africa for a year and then traveled to seven countries. Finally, she stopped in Uganda because of a primary school. She taught children from Grade One to Grade Four. Danni set up different kinds of classes for her students, such as Chinese language learning and cooking.

Sometimes Danni would cook traditional Chinese food for her students, and she also taught them to speak Putonghua. "Their smiling faces gave me energy(能量) and I enjoyed staying with them," she said.

In 2022, Danni arrived in Lebanon and became a voluntary teacher at a local school. This time she taught arts and crafts(手工艺). At the school, Danni built beautiful friendships with the children. They would run to give her hugs(拥抱) or small presents every morning, and would invite her to their homes.

She had some interesting activities in her teaching such as paper cutting and the making of paper ice cream. Some of her students were good at these and could finish the handicraft works quickly, while some needed a bit of help. The good thing was that they all worked hard.

When Grace Berbig was 7 years old, her mom became ill. Every day, Grace and her two younger sisters would write letters 1 of messages of love. These letters brought joy to their mom.2 their mother passed away three years later. After that, their father often reminded them that3 was a choice, and that it was their job to turn the heartbreaking(令人心碎的) event into4 positive(积极的). 

When Grace got into high school, she5 many organizations to offer help to others, but she6 felt like she was doing enough. "I want to7 a special way for people to help. Everyone can be a part of it, no matter 8 they have money or not. "

In October, 2018, Grace9 a club named Letters of Love at her high school to support children in fighting serious illnesses 10 letter-writing and craft-making. 

To her surprise, more than 100 students11 at the first club meeting. Letters of Love grew so fast that Grace had to raise money online to help cover the 12 of craft-making materials the next year. 

Now, Letters of Love has grown to more than 25 13 with over 1, 000 members. They 14 support for more than 60, 000 patients in children's hospitals around the world. 

Grace took a gap year(间隔年)before she started college so that she could focus on Letters of Love and15 other projects, including publishing a children's book. 

"The goal of the book is to tell children that they are never too young to change the world, "Grace said.
