One evening ， Daisy said， "I'm going to buy a packet of sweets． Does anyone want anything？"
Benny， Daisy's brother， replied， "Can you get me a packet of electricity？"
"Yes， I can，" said Daisy． Then she went out． Benny laughed ，"She can't buy electricity in packets like sweets! She "ll look foolish． " Mum said，" You mustn't say that， Benny!" "What do you know about electricity， Benny？"Dad asked．
"Electricity gives us power． It flows through wires． It's like water， in a way．" said Benny．
"You're right! Electricity comes into our flat through wires． These are connected to cables under the street，" Dad added．
"What are the cables connected to ？" asked Benny．
"They're connected to a power station，" answered Dad．
A moment later， Daisy came back．
"May I have my packet of electricity？"Benny asked．
"Here you are!" said Daisy．
