April 22nd is World Earth Day—a day to remind people to protect the earth. So on that day, our family held an activity “bottle of trash challenge”. That means the trash needs to be put in a 600ml bottle. We decided to challenge ________ and produce as little trash as possible.

My father worked online all day, so he didn’t produce any paper waste except paper napkins. He made the ________ trash in our family. My mother cooked and produced plenty of ________ waste, such as vegetable leaves, eggshells and food bags. What’s worse, we couldn’t eat up all the food of the dinner that day. So leftovers(残羹冷炙) couldn’t be ________. It was not easy for mom to ________ all the trash, but she found a way to put it all into the bottle. How ________!   My sister, a 16-year-old student, was busy preparing for her exams. She had to use paper to work out math or physics problems. She used only one side of the paper in the past. But that day, she tried to use ________ sides of the paper ________ she realized we were challenging ourselves. She did a good job!

I was different from my sister. I love snacks and drinks. So my trash was almost from them. I was highly alert( 警觉的) that I must produce less waste. I ________ had snacks or drinks. It was too difficult, but I did it! I have learnt a lot ________ this activity. I realize that everyone can produce less trash. We should start with small actions to protect the earth!

As we all know, too much trash is a big problem for our environment. A woman in Indonesia’s Java island has come up with a great idea—lending books to children in exchange for trash.

Raden Roro Hendarti, nearly 50 years old, is a librarian in Muntang village. She started a “trash library”, hoping to make children read more as well as make them realize the importance of environment protection. Each weekday, Raden puts all kinds of books on the back of her three-whoceler (三轮车) and rides to Muntang village. There, chıldren line up to exchange plastic cups, bags and other trash for books from Raden’s mobile library. After finishing the exchange, Raden carries back all the trash.

In the library where Raden works, there are thousands of books. Every time she shows up, children run to her “trash library”. They all carry trash bags, and Raden’s three-wheeler quickly fills with trash as the books fly out. Raden collects about 100kg of trash each week. It is then sorted out(分类) and sent for recycling or sale. She is happy that children spend less time on online games because of the books.

Raden plans to take the mobile library service to neighboring areas as well. She says,“We all should take care of our trash in order to fight climate (气候) change and save the earth.”

Have you ever thought of what life is like for older people, especially for those who live alone? Can they get help when they need it? Six grade-10 students from Beijing 101 Middle School looked deeper at this question and wrote a proposal to the China Youth Model Chinese People’s Political Consultative Conference(全国青少年模拟政协活动). They advised to build more seniors’ service stations (服务站) in communities. They also gave suggestions for how governments, neighborhoods, hospitals and companies can work together to make this happen.

A seniors’ service station is different from a nursing home. It offers things like daytime care, cooking, cleaning and friendship to seniors who live in their own homes. The students surveyed more than 1,100 people, about 90 percent of whom said they enjoy using the stations’ services rather than moving into a nursing home. However, there are not enough of these service stations, and many are not run very well.

The six students came up with a solution after reading more than 60 related studies, interviewing 108 people and visiting 25 different organizations. Their proposal beat out almost 100 others to win the Best Proposat award in 2021.

“This experience allows me to understand the responsibilities of us young people. Also I see the light and potential in us,” said Xu Wanqing, one of the students.

“Participating in the China Youth Model CPPCC has been good for students,” agreed their teacher and adviser Li Jie. “They’ve gotten more confidence in our society”

The students did a ________ about more than 1,100 people. Most of them like their idea. They wrote a proposal to the China Youth Model Chinese People’s Political Consultative Conference and this proposal ________ the Best Proposal award in 2021. The experience allows young people ________ the responsibilities. They ________ more confidence
