ЛЕСНАЯ СКАЗКА
Это и вправду было как в сказке. Кленовый листья| повисли на нитка осенней паутины. Лес прощается с солнцем.А при прощании| Всё бывает особенно ласково. Светлые зайчики| играли на опавших листьях . Я выбрал зайчика покрупнее| и накрыл плащом. Получилась | мягкая постель.Присесть на такую постель после долгой ходьбы | - одно удовольствие!

Переводите текст English Children in the Past
Things changed little for children during the 18th century. Chil-dren from poor families had to work as soon as they were able. When they were not working children played simple games. Dis-cipline was very strict.
For many children in the early 19th century things grew worse! The industrial revolution created many jobs and needed child labour (труд). When children worked in textile factories they often worked for more than 12 hours a day. In 1833 the Parlia¬ment passed a law that didn’t allow children under 9 to work in textile factories. It said that children aged 9 to 13 must not work for more than 12 hours a day or 48 hours a week. It also said that children aged 13 to 18 must not work for more than 69 hours a week. Nobody under 18 was allowed to work at night (from 8.30 pm to 5.30 am). Children aged 9 to 13 had 2 hours of education a day. Conditions in coalmines were also terrible. Even children at the age of 5 worked underground. In 1842 a law didn’t allow children under 10 and women to work underground. In the 19th century boys had to climb up chimneys to clean them. This bar¬baric practice was ended by the law in 1875. Gradually the law protected children more and more. In the early 19th century the churches provided schools for poor children. From 1833 the government provided them with grants. There were also schools for girls. Usually women, who ran such schools, taught girls a lit-tle reading, writing, arithmetic, music and sewing. In 1880 school became compulsory for 5 to 10 year olds. Middle class boys went to grammar schools. Discipline in 19th century schools was very strict. Beating children was normal.
