This book is that one.

The man is my uncle and he is my Maths teacher.

    In some science fiction films, people in the future have their own robots. These robots are just like humans. They help with the housework and do the most1 jobs.

    Some scientists believe that there will be such robots in the future. However, they agree it may take hundreds of years, Scientists are now trying to make robots look like people and2 the same things as us. Japanese companies have already made robots walk and dance. This kind of robot will also be fun to watch.

    But robot scientist James White disagrees. He thinks that it will be3 for a robot to do the same things as a person. For example, it's easy for a child to4and know where he or she is. Mr White thinks that robots won't be able to do this. But other scientists disagree. They think that robots will be able to talk to people.525 to 50 years.

    Robot scientists are not just trying to make robots look like people. For example, there are already robots 6 in factories. These robots look more like huge arms. They do simple jobs over and over again. People don't like to do such jobs and will get bored, But robots will7 get bored.

    In the future, there will be more robots everywhere, and humans will have8 work to do. New robots will have many different9. Some will look like humans, and others might look like10 ， After an earthquake, a snake robot can help look for people under buildings. That may not seem possible now, but computers, space rockets and even electric toothbrushes seemed impossible a hundred years ago. We never know what will happen in the future!

    A new camera made by a company named Netatmo has facial recognition software(面部识别软件). It can tell parents at work that their children have returned from school, or that a package has been taken to their home. It can also tell them if a stranger has entered their home.

    Janina Mattausch is the product marketing manager for Netatmo.

    "The common security(安全)camera at present are not that smart. They can tell if something is moving but they don't necessarily know if it's a human being or, ah, if it's your kids. They don't know the difference, so they will warn you all the time."

    When family members enter a home, the new camera "recognizes(识别)" them and sends information to the owner's smartphone. The owner can choose to see the video then or later. But if an unknown person enters a home, the camera will send the warning that will cause an alarm to sound on the owner's smartphone.

    That is what happened recently to an owner of the smart camera named Damien, He lives in Paris.

    "On a Friday I was at work, attending(出席) a big monthly meeting when my phone warned. At first I told myself, 'Oh, it must be a mistake, maybe I have to set the system again.' But the notice on my phone was telling me that there was a movement in my flat and also a face that the software did not recognize."

    He watched the video and was very surprised by what he saw. "I was watching it live on video. So I felt totally unbelievable and frozen. I asked a workmate to take me back home as fast as possible and I called the police on the way."

    With the help of the video, the police found the intruder(闯A者) later that day.
