When we want to sleep
When we want to cook dinner
When my sister wants to wash her clothes
When the carpet is clean
When we need to dry our hair
When the food is warm enough
When I want to wash up the dishes
When I want to read before sleeping
I switch on the lamp
we turn on the gas cooker
I switch off the microwave oven
my brother switches off the vacuum cleaner
we switch off the lamp.
we turn on the hair dryer
she switches on the washing machine
I switch on the dishwasher.
