I’m in 2035 now. Great changes have taken place in China. When I was 7 years old, I got a serious illness. Since then, I have dreamed of becoming a doctor when I grow up. Now my dream has come true. I work in a hospital every day to save people’s lives. There are more cutting-edge (前沿的) medical services. Doctors can do operations (手术) even when they’re far away from patients. This is because the Internet is faster now. We have 8G and robots that are smart enough.

China now is one of the most developed countries in the world. Every car on the streets is a self-driving car. They use electricity and won’t pollute the air. Robots are also widely used in every home. They can do all of the housework. When you return home, your house is clean and tidy. We’re living a comfortable life.

Travelling to the moon has become popular. I know it’s hard for you to imagine, but it’s true. People between the ages of 18 and 60 are able to travel to the moon. I just bought a ticket and I’m going to travel to the moon soon. How exciting!

In 2035, everything is fantastic. But this is because people back in 2021 were working hard. Dear Mary, work hard and create your own bright future!

Yours,

Mary from 2035

Usually schools and teachers set the class rules for students. But a Wuhan school recently tried a different way. This year, classroom rules have been made by themselves-all 46 students. During the first days of this school year, the teacher asked each student to give a list of rules to help make their class a good learning environment. The whole class shared and discussed the lists. The rule-making activity lasted a month. Finally the class had 30 rules.

Then, rule-making students were asked to sign up on the rule list—their promise to follow the rules. A poster（海报）with all the rules was put up beside the blackboard. Most of the rules are about what they should or shouldn't do. “No mobile phone calls or text messages in class” and “No loud noise in the classroom” are two examples.

Some of the rules are strict with the students who break the rules. If a student is late for class above a certain number of times, he or she will lose the chance to be an honor student（优等生）. Students say the rules work well in the classroom. “We are the rule-makers, so we have to follow the rules that we agreed to,” said one of the students.

Most of your textbooks are single-use. After leaving school, old textbooks are thrown away, which is a big waste of money and paper.

According to a study, students across the country buy 2.8 billion new textbooks every year. If the following year’s students could reuse these textbooks, it would save 20 billion yuan every year. That’s enough money to build 40, 000 primary schools.

Primary and middle school students in several Chinese cities are reusing music, arts, science and IT textbooks. That’s because students don’t have to take notes in their textbooks for these subjects, which makes them good for recycling（回收利用）.

However, these books are only a small part of the total number of textbooks. As there is no good way for redistributing（再分配）second-hand textbooks, most textbooks still end up as waste.

Changes in curricula also make it hard to reuse textbooks. “I’m among the first group of students to take classes after the changes of subjects, so I have to buy new textbooks that students didn’t use.”Sun Run, a high school student from Hangzhou said.
