10 What did the examination reveal? PAST SIMPLE
There is a great number of people who believe that robot pets will take place of real dogs and cats, while others believe that they always be human’s companions. I agree with the first point of view. In the future robots will replace pets. Firstly, you do not have to clean up after them and feed them. Secondly, they do not need a veterinarian. You will save a lot of time and money if you have a robot pet. However, there are people who believe that real pets will never be replaced by robots. Robots do not have emotions. They cannot love you for real, while real pets despite their minuses can show true emotions. People get pets when they feel lonely when they want to have a soul around, not a piece of metal. Real dogs also can protect you from burglars by catching them or barking. I cannot totally agree with that opinion because robot pets are already able to show you affection and technologies will develop more
There is also no danger that your pet will spoil your furniture or harm your children, which happens with animals. As for protection, robots can be more effective than barking dogs. They can send a signal or even a video of intruders directly to the police. To conclude, I would like to say that in the future pets will be replaced by robots because of their obvious advantages. Even now they begin to compete with animals for human’s companion place.
