To help save the planet for posterity, you need to start small. For example, to save electricity. To do this, buy energy-saving light bulbs instead of ordinary light bulbs. Unplug computers at night. Install a voltage stabilizer in the house, which equalizes the energy entering the house to the required 220 V, will allow household appliances to work normally. By the way, try to upgrade appliances to new configurations that are more economical in the use of electricity. Save water. Replace the bathtub with a shower in your home. Monitor the condition of the taps in the apartment. Install water meters. Wash dishes with a thin stream of water.

Every person has his own idea of a perfect house.

Since the time immemorial people always wanted to make their dwelling a place, where one feels comfortable and cosy, where one always wants to come back to.

A dwelling of my dream is not a flat but a two-storeyed mansion. And as a real hostess I’d like to arrange everything in the house according to my taste. Now, let me tell you about my house. When you come to me, you push a big wooden front door, wiping your feet on the door-mat, and enter the hall. The floor is covered with a fitted carpet, the wallpaper is light and has a small pattern. There’s a seat and a small table near the wall and a huge mirror above it.

Then you enter the living-room. The bright full-length curtains are drawn back, and sunshine fills the room. The living-room suite, consisting of a sideboard, a bookcase, a sofa, an elegant coffee table and three armchairs, is arranged around three walls. There’s a video system near the window.

On the ground floor there’s also a kitchen and a bathroom. The kitchen is a very large room with a big window. There is a gas cooker with a hood, two wall-cupboards and a sink unit there. Near the opposite wall there is a dishwasher, a refrigerator and a table.

Let’s go upstairs and have a look at the bedroom. This is a very cosy and warm room. The bedroom suite consists of a bed, two bedside tables and a wardrobe. The window overlooks the back yard. In my house there is also a terrace, a garage and a garden and so many other things I’d like to have; at least, in my dream house.
