CHAPTER FOUR  READING

[00:04.18]A dangerous sevant.

[00:10.74]One evening,Daisy said 'I'm going to the shop to buy a packet of sweets.

[00:19.10]Does anyone want anything? 'Benny,Daisy's brother said,'Yes.

[00:28.24]Can you get me a packet of electricity,please?'Daisy said,

[00:35.60]'Right,'and went out.Benny laughed,'Ha!Ha!I've tricked Daisy at last.

[00:45.45]She doesn't even know what electricity is.

[00:50.60]She thinks you can buy it in packets,like sweets!She'll really look foolish.'

[00:59.38]Mum said,'Do you know what electricity is?'

[01:05.93]Benny said,'Yes.Electricity flows through a wire.

[01:12.39]A meter measures the amount you use,and you get a bill for it monthly 1.

[01:20.04]It's like water,in a way.''That's not a bad explanation,'said Dad,

[01:28.82]'although electricity is much more dangerous than water.

[01:35.37]Electricity is a good servant,but a dangerous one.

[01:42.64]You must always be careful with it.

[01:47.68]Can you tell me what it looks like?'Benny scratched 2 his head.

[01:55.85]Dad said,'Nobody's ever seen electricity.It's invisible 3.

[02:04.50]But we can change it into forms of energy that we can see,hear or feel.

[02:13.46]Can you think of an example?' Benny said,'Light!

[02:21.22]The light in a light bulb. Mum said,'That's right.

[02:28.77]Do you know where electricity comes from?'Benny said,

[02:35.92]'Well,it comes into our flat through thin wires,

[02:41.99]and these are connected to thick wires that are buried under the street.'

[02:49.93]'We call the thick wires cables,'said Dad

[02:58.47]'What are they connected to?''A reservoir 4?'asked Benny.

[03:07.30]'No.You're thinking of water,' said Dad.'They're connected to a power station.

[03:18.66]That's where we make electricity.'Daisy came back.

[03:27.02]Benny said politely,'May I have my packet of electricity?'

[03:34.88]There was a grin 5 on his face'Yes,you may,'said Daisy.'Here it is.'

[03:45.23]Benny said,'But these are batteries 6!'Daisy said,'That's right.'

[03:56.56]'But...but...,'said Benny.

[04:02.23]'Daisy's right,'said Dad.'They're packets that contain electricity.

[04:11.90]The chemicals inside produce electricity.'Daisy said,

[04:20.73]'Didn't you know that,Benny?'Mum said,'Who's looking foolish now, Benny?'

[04:30.16]LISTENING
