“四菜一汤”的来历据说与哪位皇帝有关？

     I'm Joan Croft. I must have to say that I came into nursing by chance. I didn't really like my first job,

which was office work. It was all right-but that's just about all you can say about it. I stayed in the same

place with the same people around me all day and every day. Then I became a singer, which I enjoyed

very much. But after a while the singing group broke up (解散) and I had to start looking for something

else.

     Some girls have wanted to be nursed ever since they were children, but it never entered my head until

I saw an advertisement in a paper. I wrote in and thought. "Oh, well, I will give it a try." One thing I liked

about it was going away from home.

     The training itself is very interesting and most of it is just on the wards (病房), so that you very

quickly begin nursing real patients.

     I lived in the nurses' home when I arrived and I had my own room, which was very nice.

     I like nursing more than I ever thought I would. I'll always carry on nursing. I have got a boy friend,

who is a doctor, so I hope to get married sometime, but wherever I live there's sure to be a hospital in

the place and there is always a job for a nurse.
