Помогите пожалуйста перевести правильно!!!

Marie Curie was born in Warsaw on 7 th of November 1867. Her father was a
teacher of science and mathematics in a school in the town, and from him little Maria
Sklodovska - which was her Polish name - learned her first lessons in science.
Maria’s wish was to study at the Sorbonne in Paris and after many years of waiting
she finally left her native land in 1891.
Once in Paris Maria began a course of hard study and simple living. She decided
to work for two Master’s degrees-one in Physics, the other in Mathematics. Thus she
had to work twice as hard as the ordinary student.
Yet she had not enough money to live on. She lived in a bare attic in the poorest
quarter of Paris. Night after night, after her hard day’s work at the University, she
climbed to her poorly furnished room and worked at her books for hours. Though she
had been weak and ill under this hard mode of life, she worked in this way for four
years. She chose her course and nothing could turn her from it.
Among the many scientists Maria met and worked with in Paris was Pierre Curie.
Pierre Curie, born in 1859 in Paris, was the son of a doctor, and from childhood he
liked science. At sixteen, he was a Bachelor of Science and he took his Master’s
degree in Physics when he was eighteen. When he met Maria Sklodovska he was
thirty five years old and famous throughout Europe for his discoveries in magnetism.
But in spite of the honour he brought to France by his discoveries, the French
Government could only spare him a very meagre salary as a reward, and the
University of Paris refused him a laboratory of his own for his researches.
Loving science more than anything else, Pierre Curie and Maria Sklodovska very
soon became the closest friends. They worked together constantly and discussed
many problems of their researches. After little more than a year they fell in love with
each other, and in 1895 Maria Sklodovska became Mme. Curie. Their marriage was
not only to be a very happy one but also one of the greatest scientific partnerships.
