birds and animals can break into them and they smell.
Washing
There is a washing line for every flat in the garden next to the car park.Please only dry your
washing on these lines so it does not disturb (干扰) people in the ground floor flats.
Cleaning
The main stairs are cleaned twice a week by the Association, so please try to keep them tidy
and clean and do not leave furniture or bags on the stairs or in the hallways.
Lights
The main lights are on a timer and they stay on for five minutes when you press them.Please
tell the Association if any lights are not working.
Noise
Residents are asked to keep noise to a minimum.Loud music, etc.can disturb other people and
the Association will get in touch with you if you make too much noise.
Safety
Make sure the main outside door is always locked and do not let anyone in to the main
building unless you know who they are.Sometimes people try to get in to the main stairs and then
break into flats, so do not let people in unless they are coming to see you.
Parking
Each flat has one car parking space.These are numbered and are at the back of the
building.Do not use another resident's space.If you have more than one car you will have to park it
on the road.Do not park where you are blocking entrances.
Problems
If you have any problems or questions, please call the Association at 0800 096 9000.

My Lowcarbon Life
It's
our
duty
to protect
the
environment.
As we all know, with the global warming and energy consumption, the environment is
becoming worse and worse.It is very important for us to start with a lowcarbon lifestyle.But how
can we live a low carbon life? Here are my ideas.
Firstly, it is a very good idea for us to go to school on foot instead of by car.It is good for the
environment and our health as well.Secondly, remember to turn off the lights, fans and computers
when we leave the classrooms.Thirdly, it is important for us to turn off the tap when we finish
using the water.We can reuse water, too.For example, we can reuse the water to water the flowers
or trees.At last, try to use the cloth shopping bags instead of plastic bags when we go shopping.(In
addition, it is important for us to use fewer fast food boxes or chopsticks so that we can reduce the
white pollution.)
I believe our life will become better and better if we can do these things.
Lower
carbon,
happier
life.Let's
take
action.
