Joan worked in a hospital as a nurse. One evening there was a big dance at the hospital. Most of the doctors and nurses would be there, but of course somebody had to be left to look after the sick children, and Joan was not of the lucky ones. She liked dancing very much, so when she had to start work that evening while her friends were getting ready to go to the dance, she felt very sorry for herself.
She went to each sick child one after another and said good-night, until she came to one little boy, Nick. He was eleven years old, but he was already able to talk like an adult. Poor Nick was badly ill, and now he was not able to move any part of his body except his hands. Joan knew he would never get any better, but he was always happy and always thinking about other people instead of about himself.
Nick knew that Joan loved dancing, so now when she came to say good-night to him, he greeted her with the words, “I’m very sorry that you have to miss the dance because of us. But we are going to have a party for you. If you look in my drawer, you’ll find a piece of cake. I saved it from my supper today, so it’s quite fresh. And there is also a dollar there, you can buy something to drink with that. And I’d get up and dance with you myself if I was able to.”
Suddenly the hospital dance seemed very far away and not at all important to Joan.
【小题1】Joan felt unlucky that evening mainly because______.

Driving a car at a high speed along a highway seems to be fun. You only need to follow the bright traffic signs beside the highway and it will take you where you wish to go.
But to a London taxi driver, driving is not an easy job. A taxi driver needs to have not only good driving skills but also a good knowledge of the city of London, from the loneliest street to the most popular restaurant around. He has to be at the service of all kinds of passengers at all times.
A London taxi driver said the following about his job.
During the night it is usual for him to stop two or three times for some food. He said," I never drink when I am driving, or I would lose my license."
He normally goes home between two and three o'clock in the morning. There are times he has to stay longer and try to make more runs. He said, “That's the worst thing about working for yourself. If you don't make money, no one is gong to give it to you."
London taxi drivers not only "take" but also "give". Every summer hundreds of poor children from London go for a day at the sea-by taxi. Their rides are paid by the taxi drivers. At the sea, they are met by the mayor(市长),and a lunch party is also held for the taxi drivers and the children. After a happy day's running around the beaches and visiting the market there, the children go home again by taxi, free of charge of course.
