【推荐1】A little battery puts out a little bit of electricity, so you can use it safely for your experiments. But the electricity that comes through the wires in your house or school is much more powerful.     1     .

Inside the walls where you live or study, there are big wires that carry electricity. When you plug in a light or radio or other electrical appliance, you are putting the light or radio in the path way of the electricity. You have heard adults warn, “     2    ，‘ Now do you know why? If you did, you would become part of the electrical path way.

    3     The electrical current coming through the wires to the wall plug is so strong that it would hurt a lot if you stuck your finger in the plug. Put your finger in there and it could be you, rather than the light bulb, that becomes part of the electrical path way. And that would hurt!

What if you held a piece of metal, like a fork or knife, and stuck it into the wall plug? Don't do it. Why? It's because metals also conduct electricity.     4    

Don't touch any electrical appliance when you are wet. Can you think why? It's because water is a good conductor of electricity. When your hands are wet or when your body is in a bathtub full of water, the electricity could flow right through you and give you an awful shock, or even kill you.

Electricity is very useful, but it can be dangerous.     5    If so, electricity can better serve you, instead of hurting you.

【推荐3】Have you ever forgotten to lock the door of your house? Or, have you ever forgotten to switch off the TV or computer? These kinds of things happen to us all the time, waste resources, and can sometimes lead to problems. However, in the not-too-distant future, we will be living in smart homes that will lock the door for us when we are away and remember to switch off the TV when we forget.     1    

Intelligent Controls

Today, we have to use switches for our lights, knobs for our appliances, and remote controls for our TVs and air conditioners.    2    The future home will use integrated sensors to tell when you leave home each morning, and then go into an energy-efficient mode all by itself. You will no longer have to think about turning switches on and off yourself. Your home will also learn your daily routine and preferences, so everything will be ready for you when you get home each evening. Your lights will come on the instant you enter thedoor along with your favourite musie or TV programmes, and you will find your dinner already prepared for you. All controls will respond to voice commands, so if you want to change your routine, you just say aloud what you want and the home system will obey.

Regular Health Checks

In addition, your smart home will be monitoring your health for you every day. Your bed, for example, will record how well you sleep every night. It will also be checking your body weight. If you start to have sleep or weight problems, it will send a warming to your phone. It will also give you suggestions on a healthier diet and how to sleep better.     3    They can warn you early if there is something abnormal or if you have a critical illness, such as cancer, and potentially save your life.

No More Disasters

Smart homes will be able to prevent serious damage from accidents. For example, if a water pipe starts leaking, or if there is a short in the electrical wiring, your smart home will detect it and provide you with the relevant information.     4    

This smart technology is not a fantasy.     5    In this sense, the home of tomorrow is already the home of today. Nevertheless, it will take some years before most new homes begin to use this new technology.
