Today I want to tell about Flora in USA Great Britain and Kazahstan.At first sight(с первого взгляда) , I thought that there are practically no Flora.But I was mistaken.There are a lot of Flora there.I will name some.
In Usa there are a lot  of berrys, some dwarf willows and there are birchs.
And some cereals
In Great Britain there are a lot of forests and beautiful flowers.For example wild daffodil, lilies, purple orchids and primroses. 
In Kazahstan there are a lot of forests too.But Flora is not very big because half a countrie is sand.Also there are some flowers.
Thank you for you attention!

Man has always been a builder.The kind of house he built in the beginning depended on the climate, on his enemies and on the building material at hand. The ancient Egyptians built very simple houses by present standards.Having dried the bricks in the sun they put up four walls and above these they placed a flat roof. The roof was flat because there was very little rain in Egypt.Their pyramids and monuments, sphinxes and palaces arouse our wonder to this day.In our country architecture flourished for the first time in Kiev Russ.The churches of the time were strong buildings with thick walls and small windows.They often had to serve as fortresses during enemy invasions. At present, the building industry is the largest in Belarus and it holds an important place in the National Economy of our country.Builders use many new materials such as reinforced concrete, precast concrete, light weight concrete, gas concrete, many decorative materials, oil paints, wall paper. Synthetics are among them.The assembly method is developing into the main method of apartment and industrial construction.Transport brings a complete flat to the prepared foundations of a building. A powerful gantry-crane lifts the 18 – 20 ton flat and carefully sets it on the foundation.
