Пожалуйста переведите на русский!
A woman met me in Lowood school. She took my things and we walked to a big house. We went into the house. A teacher came and took me by the hand. The woman went away with my things and the teacher took me into a long room with a lot of large tables round it. Girls of nine to twelve years old sat on benches round the tables. They all had brown dresses on. It was dark and cold in the room.
"Sit down on one of the benches," said the teacher. "The girls are learning their lessons for tomorrow. They will soon finish and you will have supper. Then you will go to bed."
For supper we had a piece of bread and some water. After that we marched to the bedroom. It was a large room with many beds. Two girls slept in each bed. In ten minutes the teacher took away the light.
The night passed quickly. In the morning it was very cold in the room. We washed our faces in water with ice. Then we marched to the cold schoolroom where lessons began. We read the Bible and did exercises in our exercise-books. This lasted for an hour. Then we marched to another room for breakfast. After breakfast there was reading, writing, history and geography. Before dinner we went into the cold, windy garden for an hour. -
For dinner we had some bad meat and potatoes. I ate what I could. Then we marched back to the school-room and had our lessons till five o'clock.
The next day began as before, but we could not wash. The water in the wash-room was ice.
During January, February and March there was much snow in the garden. We had no boots and could not walk far. The rooms were very cold. The food was bad and in spring many of the pupils were ill with typhus. In May Lowood school was a hospital. Forty-five girls out of eighty were ill. We had no lessons. Many pupils went home and died there. Some girls died in the school.
