Древесина является самым древним строительным материалом. По сравнению со стальным брусом он легче, дешевле, проще в обработке, а его механические свойства хорошие. С другой стороны, древесина имеет определенные недостатки. Во-первых, он горит и поэтому не подходит для огнестойких зданий. Во-вторых, он разлагается.
Сеголня количество древесины используется для огромного числа целей. В строительстве также используется древесина.
Древесина - это название, применяемое к материалу, полученному из деревьев. Древесина, используемая для строительных целей, делится на две группы: хвойные и лиственные. Древесина лиственных пород используется главным образом в декоративных целях, например, для облицовки мебели, а некоторые из них выбраны для структурного использования из-за их высокой прочности и долговечности. В современном строительстве древесина часто используется для оконных и дверных рам, напольных покрытий, заборов и ворот, настенных панелей, для временных построек и неокрашенных внутренних деревянных конструкций.
Древесина не может быть использована ни для работы плотников, ни для столярных работ сразу же после ее вырубки из-за большого количества сока, который в ней содержится. Устранение этой влаги увеличивает прочность, долговечность и упругость древесины.
English educational system is quite different from what we have in Russia. It is class-divided. There some state schools and some private ones.
State schools are infant, junior or secondary. British boys and girls begin to go to school at the age of 5. They draw pictures, sing songs, listen to the stories and tales. British children begin to read and write when they enter the infant schools. Young children are divided into two groups, according to their mental abilities. Children leave infant schools when they are 7. Then they go to study at junior schools where they learn to write, read and do mathematics. Their school subjects are History, English, Geography, Arithmetic, Arts, Music, Swimming and some others. When the pupils enter the junior schools they pass abilities test. According to the results of the test and thus their intellectual potential they are divided into three groups. Boys and girls spend four years studying at junior schools.
Then they pass examinations again and enter the secondary schools. There different types of secondary schools in Britain. They are: grammar schools, modern schools and comprehensive schools. English boys and girls attend secondary schools from 11 till 16. They don't go to schools on Saturdays and Sundays. In the modern schools pupils do not learn foreign languages. In grammar schools pupils receive better theoretical education. And the other school type is comprehensive schools. Almost all secondary pupils ( around 90 per cent ) go there.
There are also private schools in England. Boys and girls do not study together there. It is common that aristocracy sons go to these schools and parents pay a lot of money for their education. These schools are called public. Independent and preparatory schools are private ones too. They prepare children for public schools and take money for the training. The teachers of the private schools can pay more attention to each of the pupils personally. It is possible to enter the best English universities after leaving public schools. After finishing grammar schools pupils have good knowledge and may continue studying in colleges and universities.
English pupils wear school uniform. It is one of the oldest country's traditions. A boy's uniform includes a school cap, a tie and a blazer. A girl's uniform consists of a hat, a coat, a skirt and a blouse. The uniforms vary from school to school. Usually, they are dark.
