turn the lights on or off. You can also operate the systems from outside the house. You can turn on the heating so that the house is warm when you return. You can open and close curtains and turn on lights so that people think you are at home. The system can call your mobile to tell you that you’ve had a visitor or received mail and you can let visitors into your house if you want to. What’s more, the systems could be connected to other buildings. The security system could be connected to the police station, so that it alerts the police if you have an intruder. The fridge could be linked to the local supermarket, so that it can order products, which will be waiting for you when you get home. So, let’s look at this house in the diagram. First of all, as the family arrives home, they activate the systems inside the house from inside the car – if they haven’t already done so previously, of course. Above the garage here, there’s a motion detector. This will detect any movement outside the house, whether it’s an approaching vehicle or a person. When you are inside the house, you will know that you have a visitor well before they arrive. Outside the house, you can see that there are various external systems. External systems can check and maintain the temperature and cleanliness of a swimming pool or irrigate the garden, for example. Now, as you come round the front door here, there are security panels in the entrance area. These would be more sophisticated than conventional alarms – panels like these have an alarm, but also digital cameras and mechanisms for activating locks. Now, inside the house, there would be various
areas where parts of the system would function from. In this house, the master control is downstairs on the ground floor – the master control is the central part of the system – rather like a server to a system of computers. Upstairs, at the top of the house is the multimedia connection. This connects all the other systems to television screens and smaller computer screens around the house. In this house, the telephone connection is in a different location, but, of course, that could also be part of the multimedia apparatus in another house. OK, now, down in the kitchen – personally, I think some of the kitchen features are the most interesting to talk about. Take the fridge, for example …

and blown into shape inside a mould. It emerges as a brand new glass bottle or jar. Each container is rigorously checked in a series of quality controls.
Extract 2 Voice: The thermostat takes all the guesswork out of ironing. The user can preset the exact required temperature on the dial depending on the fabric being ironed. He or she can be confident that the correct heat is being maintained and that there is no risk of burning. A heat-sensitive contact cuts the supply as soon as a selected temperature is reached. When the iron cools, the current is resumed.
Extract 3 Voice: Brighton is a city on the south coast. It has many attractions that young visitors can enjoy. It’s more or less directly south of London and is about an hour by train. Eastbourne and Hastings are smaller seaside resorts to the east of Brighton. Hastings is the larger of the two and has more in the way of leisure facilities. Another seaside town – this time further west in Dorset – is Bournemouth. Bournemouth is a large town popular with holidaymakers …
Extract 4 Voice: Early dwellings in Pompeii were built around an atrium, a large open main hall. There was usually a small opening in the ceiling, the compluvium, through which light and air were filtered. The impluvium was a hole in the floor which collected rainwater when it entered through the compluvium.
Extract 5 Voice: There are four chambers, two superior atria and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The right ventricle discharges into the lungs to oxygenate the blood. The left ventricle discharges blood that circulates around the rest of the body via the aorta.
Extract 6 Voice: The biggest leap in the number of female smokers was between 1992 and 1993 when 30,000 more women smoked. By 1993, there were more female than male smokers. For three years, the number of women smoking remained fairly constant, but then between 1996 and 1997, there was another increase.
