满分范文

There are many different kinds of inventions in the world. Now, let me tell you something about one of my inventions.

My invention is called the “Flying Bike”. It has two wheels and two wings, so it looks like a bird. You can ride it on the ground like a normal bike, and it can also fly in the sky. It can even take pictures and talk with you! My bike is very fast. Best of all, it uses solar power, so it’s very good for the environment.

However, it still has some problems. First, its wings are too big, so it’s sometimes hard to park. Second, when it’s cloudy, it doesn’t have enough power to fly for a long time. I hope I can make it smaller and find a better way to store energy.

满分范文

The invention of DeepSeek has made AI a hot topic among people in our society. It has become an important part of our life.

In some ways, AI is good for us. It makes our life more convenient and comfortable. For example, we can gain knowledge on every subject from it in a few seconds. What’s more, AI can help us to do some dangerous and hard jobs.

However, it also brings us some problems. Students can’t think by themselves with the help of AI and they can’t study carefully in class. Moreover, AI will take the place of humans in some jobs, increasing the risk of unemployment.

In my opinion, every coin has two sides. We should use AI wisely and view it as a helper to improve our life.
