One evening, Daisy said, ‘I’m going to buy a packet of sweets .Does anyone want anything?’

Benny, Daisy’s brother, said, ‘Yes, Can you get me a packet of electricity, please?’

Daisy said, ‘Ok,’ and went out. Benny laughed, ‘Ha! Ha! I’ve tricked Daisy at last. She doesn’t even know what electricity is. She thinks that she can buy it in packets, like sweets! She’ll really look foolish.’

Mum said, ‘Do you know what electricity is?’

Benny said, ‘Yes. Electricity flows through a wire. A meter measures the amount you use, and you get a bill for it monthly. It’s like water, in a way.’

‘That’s not a bad explanation,’ said Dad, ‘although electricity is much more dangerous than water. Electricity is a good servant, but a dangerous one. You must always be careful with it. Can you tell me what it looks like?’

“这个解释还可以。”爸爸说，“但是电比水危险多了。电就好似一个优秀的仆人，但是同时又很危险。你必须对它保持警惕。你能告诉我电视什么样子的吗？”

Dad said, ‘Nobody’s ever seen electricity. It’s invisible. But we can change it into different forms of energy that we can see, hear or feel. Can you think of an example?’

Benny said, ‘Light! The light in a light bulb.’

Mum said, ‘That’s right. Do you know where electricity comes from?’

Benny said, ‘Well, it comes into our flat through thin wires, and these are connected to thick wires that buried under the street.’

‘We call the thick wires cables,’ said Dad. ‘What are they connected to?’

“我们把那些粗的电线叫做电缆。”爸爸说，“它们连接到什么？”

‘A power station, ‘said Benny.

“发电站。”本尼说。

Daisy then came back. Benny asked politely, ‘May I have my packet of electricity, please?’There was a grin on his face.

‘Yes, you may,’ said Daisy. ‘Here it is. ’Benny said, ‘But these are batteries!’Daisy said, ‘That’s right.’

“当然”黛西说，“给你。”本尼说：“可是这只是电池！”黛西说：“对啊。”

‘But…but…,’ said Benny.

“但是……但是……”本尼支支吾吾。

‘Daisy’s right,’ said Dad. ‘They’re packets that contain electricity. The chemicals inside produce electricity. ’

“黛西做的不错，”爸爸说，“这里面也包含电量了。电池里的化学物质会制造电能。”

Daisy asked, ‘Didn’t you know that, Benny?’

Mum said, ‘who’s looking foolish now, Benny?’
