he Importance of Electricity
When you go to work in the morning and find that traffic lights don’t
work,the traffic jam will certainly happen.A patient needs to be operated on at
once.What will happen if the operation cannot be made because of the
electricity.Without electricity,we can neither watch TV,listen to the tape,nor
chat on line.Electricity is closely related to our daily life.
