When I was a child, I was always dreaming of what I could become when I grew up. Become a singer? Become a painter? Become an actor? These are some glamorous professions, and what I want to be the most is an inventor.

Although the inventor is a behind-the-scenes worker, he can make a great contribution to human development. It can make people's lives less tired and make people happier every day.

If I were an inventor, I would invent many things that would be convenient for people to live on. Start with people's housing starts! If I were an inventor, I would invent a very advanced door. The shape of this door is not different from the ordinary one, but it has many functions. First of all, when the noise coming from the corridor, the door can be according to the master's voice as he opened the door ahead of time, when the owner came to the door it say: "master, welcome home!" Then the door closes. The advantage of this design is that the owners no longer have to go out with keys. Second, if there is a bad guy to destroy the door, the door have a security alarm system, can let the neighbors know there is a thief, the thief will soon be away. And the door will also send the information to the owner's mobile phone for the first time, telling the host that there is a bad guy and need to deal with it as soon as possible. Finally, the door has the function of weather forecasting. At seven o 'clock in the morning, it will report on time and report the weather and the situation of the day. If the weather forecast says it's going to rain, the door will offer an umbrella before its owner goes out, and if it's a big summer it will also offer a sunblock and sunscreen. The invention guarantees home safety, improves living standards and makes people's lives more comfortable.

If I were an inventor, I wanted to invent a medicine that would delay people's life slightly. Because I know that it is impossible to live forever, and if you can live forever, there will be more and more people in the world. A slight delay is the ability to make a person's life a little longer. The invention is mainly used for the immediate death of the hospital, but to the people who want to see the last of their loved ones. Or people who are in a car accident or other sudden death. Because of this invention, they can be able to see the last part of their family, leaving them with the words they want to say, without regret.

If I were an inventor, I would invent an emotional robot. Scientists say robots are mechanical, unemotional and can't understand what people really need. And I'm going to invent this robot, which has its own personality, apart from being able to do the housework, the laundry, the cooking. Owners can choose robots with different personalities.

There are gentle, considerate, or tyrants. The charm value of the robot can be acquired by itself. At that time, the robot is more than just a machine, it can be your family, your friends, more like your child. He's hungry and needs you to feed him. When you are sad it will hug you, stand beside you and comfort you and tell you jokes. When you're nervous, it encourages you and tells you it's ok. When you are happy, it will give you all kinds of celebrations, standing next to you and dancing, more than you are happy. But the baby robot also dies, for example, when it dies of starvation, or parts that are too long and die. But you can rest assured that the life of the robot baby is usually a hundred years old, enough to accompany you forever.

If I am the inventor, I would also like to invent a lot of things to benefit mankind, I'm not in order to let everyone thank me, let me earn a lot of money, but in order to let people all over the world have a safe, happy, happy, carefree, so I am very satisfied. I would like to be an inventor. For this dream, I must study hard and go to a good university in the future. I can get rid of the word "if" and realize my dream.
