AI is not a threat to human being In this era of Artificial Intelligence, big data and cloud server become the hottest words. However, some people are afraid of developing AI. They believe that scientists are creating "Skynet", and robots are going to govern the world. Based on my observations, I want to stand up for the research in AI. Whenever our ancestors overcome their dread of fire, they could have a cooked meal. Whenever people embrace electricity, our cities could shine as stars at night. Fear is an inhibitor to progress. Whenever we harness the power of AI, our world will be totally different. AI is not a formidable competitor who will reduce our working opportunities. Instead, I think it reminds us that the cognitive and emotional skills are the priceless treasures of the human beings. Besides, it can be our credible helper who always gives us calm and accurate judgements. ==== I want to improve my use of words~ Thanks for any correction!

The Sharing Economy Nowadays, more and more people join the so-called "sharing economy". That is to say, they rent something, use it, and return it instead of owning it. While some people argue that laws and rules are not yet prepared to regularize these business behaviors, I've always believed that it's a great idea. Firstly, people can save a lot of money by sharing things. For example, we can call Uber instead of owning a car, and we can share a nice tuxedo instead of purchasing it. Last summer, I wanted to go camping with my friends, but camping equipment is very expensive. Surprisingly, I found someone who had a set of camping equipment. He was willing to share with us at a low price because he didn't need it at that time. As a result, we had a nice trip and saved a lot of money. Secondly, people are willing to try new things because the concept of sharing can reduce the cost of wrong choices. For example, when I was a student, I wanted to use a quadcopter in the final project of a course, but quadcopters are expensive. Besides, I was a beginner and I was not familiar with various kinds of drones, so it's hard to decide which one to buy. In order to make sure I can accomplish my project, I gave up this idea and just wrote a report instead. If I could have found someone who can have shared a quadcopter with me at that time, I could do better. So that's why I stand up for developing the sharing economy. Thanks for any correction!

My favorite comic book is "Attack on Titan" There are many interesting comics, but my favorite one is "Attack on Titan". That's because I believe that life is a struggle, and this comics impressively depicts how people deal with the difficulties in their lives. The story happened in an imaginary world. People dwell in cities behind the protection of three huge walls to save them from Titan - a group of relentless monsters. My favorite scene is when Titan destroyed the first wall, people were all escaping. But a rich businessman put his carriages in front of the gate and no one could escape from that gate. What a selfish person. At this moment, my favorite character- Mikasa - showed up. She was not afraid of the power of the businessman and asked him to remove his carriage with a threat of her knife. I really admire her bravery and her attitude toward difficulties in her life. So that's why I love the comics - "Attack on Titan". Thanks for any correction!
