Write your story
My grandma often tells me about life in the past. It was very different from today.
In the past, people traveled by foot or horse. There were no cars, buses, or trains. If they needed to go far, it took a long time, even years.
Today, transportation is much easier. We have taxis, cruise ships 邮轮, and electric cars. People can travel quickly and comfortably. Some even fly in airplanes to go to other countries in shorter time.
SAMPLE
Write your story
In the old days, people bought things from small local shops. They used paper money, coins or traded goods. There were no supermarkets or online shopping.
Nowadays, shopping is very convenient. We have big supermarkets with everything we need. We can also shop online and get things delivered to our homes. We can also pay money with our phones in a second. It’s much simpler than before.

Life has changed so much! We enjoy many things that people in the past could only dream of. I feel lucky to live in this modern world.

Sample
Over the past several years, my community has changed a lot. The biggest change is the development of new parks and green spaces.
Project
Sample
In the past, there were only a few small, old playgrounds in our community. They were not well-maintained and lacked facilities. However, in recent years, the local government has focused on improving the living environment. They built several new parks with modern playgrounds, walking paths, and beautiful gardens. These parks have become popular spots for families, elders, and young people.
Project
Sample
This change has brought many benefits. People now have better places to relax, exercise, and spend time with their families. The parks also help improve the air quality and make the community more attractive. I feel proud that our community has become a better place to live.
Project
Sample
Over the past ten years, my community has changed a lot. The biggest change I have noticed is the development of new shopping centers and businesses.
Project
Sample
In the past, there were only a few small shops and markets in our community. People had limited choices for shopping and often had to travel far to find what they needed. However, in recent years, several large shopping malls and supermarkets like Freshippo have been built. These new shopping centers offer a wide variety of goods, from groceries to clothing to electronics. They also have restaurants, cafes, and entertainment options.
Project
Sample
This change has made shopping much more convenient for residents. We no longer have to travel far to find what we need. The new businesses have also created job opportunities for people in the community. I feel proud that our community has become a better place to live.
