Robot

  "1+1=2," a robot beeped. Have you ever imagined your teacher being a robot? Do you think our teachers should be robots? I do for the following reasons: It can defend a whole school, teach easily, and work harder than teachers.

  First, it can defend a whole school from emergencies. Many intruders come to schools. Teachers can't call the cops fast enough. They might harm us. People die when murderers attack them. The cops would take sometime to get to the school. The intruder might have left the school by the time the cops come. Even if the intruders have left, cops risk their lives. A robot, can scare an intruder away by moving towards an intruder with a weapon. Bullets can barely affect a robot. However, it can kill an intruder.

  Next, it can teach easily. A lot of class time gets wasted. Teachers might need to turn the TV on, and it might be on the other side of the room. They might need to search in the internet to show students something. They might need to turn the projector on. Teachers have to move from place to place. This wastes a lot of time. Robots can connect themselves to the TV, internet, and projector all at once. The robot can show preschoolers something like this: 1 + 1 = 2. They can repeat it again and again. It can teach people things way faster than teachers can.

  Lastly, robots can work harder than a teacher can. During the school year, students make teachers tired. Teachers get tired, so they don't correct homework. Since robots never get tired, they can work 24 hours a day. A teacher can get tired. They can work 6-8 hours a day. Robots can finish correcting things, such as tests, homework, classwork, and other types of work.

As you can see, robots can defend a whole school, teach easily, and work harder than teachers. Therefore, robots should replace teachers.
