答案：
1. year's—years

3. 删掉an.admission是不可数名词。
4. Therefore—So.此处隐藏着一个so...that...结构
5. 删掉in.teach school为固定搭配，教书
6. until—after.据时间顺序，她是1849年从医学院毕业后决定去巴黎深造。
7. farther—further.farther只能做副词，further既可以做副词也可以做动词，此处就是further做动词，并带有宾语her education。
8. 在difficult前加it.it做形式宾语，替代不定式to start her own practice。
