单选题 Elizabeth Blackwell was born in England in 1821, and emigrated (移民) to New York City when she was ten years old. One day she decided that she wanted to become a doctor. That was nearly impossible for a woman in the middle of the nineteenth century. After writing many letters to medical schools, she was finally accepted by a doctor in Philadelphia. She, taught in a school and gave music lessons to earn enough money for her tuition.
In 1849, after graduation from medical school, she decided to continue her education in Paris. She wanted to be a surgeon, but a serious eye illness forced her to give up the idea.
Upon returning to the U. S. , she found it difficult to start her own practice because she was a woman.
