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.

    Today, a man talked very loud on his phone on a train between Malvern and Reading, making many passengers upset. I wonder how he would react if I were to read my newspaperoutloudonthetrain, Ihave never had the courage to do it, though.

    Why not give it a try? Perhaps you should take lessons on a

    musical instrument. The late musician Dennis Brian is said to have

    asked a fellow train passenger to turn off his radio. When his

    request was refused, he took out his French horn(号) and started to practice.

    I don't see how musical instruments can help improve manners in public. Don't do to others what you wouldn't like to be done to yourself. Once, a passenger next to me talked out loud on his mobile phone. I left my seat quietly, giving him some privacy to finish his conversation. He realized this and apologised to me. When his phone rang again later, he left his seat to answer it. You see, a bit of respect and cooperation can do the job better.

    I did read my newspaper out loud on a train, and it turned out well. The guy took it in good part, and we chatted happily all the way to Edinburgh.

    I have not tried reading my newspaper out loud on a train, but ,several years ago, I read some chapters from Harry Porter to my bored and noisy children. Several passengers seemed to appreciate what I did.

Dear Mom and Dad,

    I'm afraid I have some very bad news for you. I have been very naughty and the school master is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer. The trouble started last night when I was smoking a cigarette in bed. As I was smoking, I heard footsteps coming towards the room .I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste--paper basket. It caught fire.

    There was a curtain near the waste --paper basket. It caught fire too. Soon the whole room was burning. The master phoned the fire brigade. The school is a long way from the town and before the fire brigade arrived, the whole school was on fire. The master said that the fire was all my fault and I must pay for the damage. She will send you a bill for about a million dollars.

    I'm very sorry for this.

    Much love

Sarah

    Many of us love July because it's the month when nature's berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia's fields are little powerhouses of nutritional protection.

    Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

    When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat "ice cream". For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

    If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a "soft-serve" creamy dessert, to be eaten right away. This makes a fun activity for a children's party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity (湿度).

    In very cold climates, there is a constant danger of developing hypothermia, which is a life-threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

    In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life-threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.
