Electricity
Electricity is energy.Just like we eat hamburgers and chocolate to keep us going,machines “eat” electricity to keep them going.In our homes,electricity runs the lights,televisions,toys and other things.It’s hard to imagine what our lives would be like without electricity.
However,if electricity is used unsafely,it can cause a fire or make someone dead.But why is electricity a danger?
A conductor(导体) is something that electricity can go through easily.Water is a great conductor.In fact,our bodies are mostly water.It means electricity can also travel easily through us.
The electricity that reaches our homes travels in a line.The energy is provided by power plants.(发电厂) Then the power lines carry the electricity to our homes.There lines are great electric conductors.So it is dangerous to touch them.
Ever when a small electric current(电流) passes through our body,we will feel painful.Electricity current can burn our skin and cause a problem for heartbeat,possibly leading to death.
Electricity is necessary and helpful in our daily life.We can’t live without it but we must use it carefully and safely.
