Elizabeth Blackwell was the first woman doctor in the United States. Her success opened the way for other women who wanted to do more than nursing. She was born in England in 1821 and her family moved to America when she was eleven years old.

    The Blackwell girls received the same education as their brothers. This was most unusual in those days. Their father died young and they had very little money to live on. Elizabeth and her sisters taught at school. Then a woman dying of cancer urged Elizabeth to study medicine, saying that a woman doctor would have saved her from her worst sufferings. Nearly everyone said a girl should not go to medical school, but she managed to enter Geneva College in New York State. She graduated in 1849 at the head of her class and received the first medical degree ever given to a woman.

    Next, Dr. Blackwell went to Paris. Her only chance of training was in a hospital where women came to have their babies. Four months later, while she was working in the French hospital, her left eye became dangerously infected (感染). She lost the eye. She was very disappointed. But she was soon back at work again, this time in London, England. There she met many famous scientists.

    In 1859, Elizabeth Blackwell was officially recognized as a doctor in Great Britain — the first woman to be honored. She was the inspiration of Elizabeth Garrett, who began the women's medical movement in England. Florence Nightingale, founder of the practice of nursing by women, was another of her friends.

    Dr. Blackwell died in 1910 at the age of 89.

    What Theresa Loe is doing proves that a large farm isn't a prerequisite for a modern grow-your-own lifestyle. On a mere 1/10 of an acre in Los Angeles, Loe and her family grow, can(装罐)and preserve much of the food they consume.

    Loe is a master food preserver, gardener and canning expert. She also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control what's on their plate.

Loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “I got into cooking my own food and started growing my own herbs (香草) and foods for that fresh flavor,” she said. Engineer by day, Loe learned cooking at night school. She ultimately purchased a small piece of land with her husband and began growing their own foods.

    “I teach people how to live farm-fresh without a farm,” Loe said. Through her website Loe emphasizes that “anybody can do this anywhere.” Got an apartment with a balcony （阳台）? Plant some herbs. A window? Perfect spot for growing. Start with herbs, she recommends, because “they're very forgiving.” Just a little of the herbs “can take your regular cooking to a whole new level,” she added. “I think it's a great place to start.” “Then? Try growing something from a seed, she said, like a tomato or some tea.”

    Canning is a natural extension of the planting she does. With every planted food. Loe noted, there's a moment when it's bursting with its absolute peak flavor. “I try and keep it in a time capsule in a canning jar,” Loe said. “Canning for me is about knowing what's in your food, knowing where it comes from.”

    In addition to being more in touch with the food she's eating, another joy comes from passing this knowledge and this desire for good food to her children: “Influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture,” she said, “that if we don't take care of the earth, no one will.”
