A young man worked very hard at his lessons. He was too busy to have a rest. At last, he became ill, so he couldn't go to sleep. Every night, when he went to bed, he closed his eyes and tried to sleep. But he always stayed awake and couldn't fall asleep.

    After some days, he decided to see a doctor.” I just can't go to sleep at night. What should I do? Could you please help me?”

    “I have a suggestion(建议)，”said the doctor. “Try counting numbers. By the time you reach one thousand, you'll be asleep. I'm sure of it.”

    The next day the man returned to the doctor's office. “Well,” said the doctor, how are you today? Did you try my suggestion?”

    The man still looked tired. “Yes,” he said, “I tried counting one, two, three-up to one thousand. But when I reached five hundred and sixty-nine, I began to feel sleepy. I had to get up and drink some tea so that I could go on counting up to one thousand. But then I still couldn't fall asleep.”

    Once there was a parrot on sale in a pet store. It was a beautiful red and blue bird.  It sat on a perch in the middle of the store so that everyone could see it when they came in. The owner was very proud of it and asked a high price for it.

    One day a man went into the store. "That's a beautiful bird," he said to the pet store owner. "But why is it so expensive? Is it an unusual bird?"

    "No, it's not very unusual. It's expensive because it can talk," the pet store owner said.

    "I see. How can I make it talk?" the man asked.

    The pet store owner asked him, "Do you see those strings tied to each of the bird's legs?"

    "Yes," the man answered.

    "Well, you pull those strings," the pet store owner told him."That will make the parrot talk."

    The man asked, "Do you mind if I try?"

    "Not at all," the pet store owner said.

    The man walked up to the parrot and pulled the string on its left leg. The parrot said, "Good morning."

    The man pulled the string on the parrot's right leg. This time the parrot said, "How are you today?"

    "That's not very interesting," said the man."Any parrot could do that." Then he laughed, "But what would happen if I pulled both strings at the same time?"

    "I'll fall off my perch, you fool!"the parrot said.

    In the 1920s, the airlines were just beginning. It was unusual for people to travel by air because it was expensive and dangerous. In those days, there were no flight attendants (服务生) to look after the passengers. Young men, or “stewards” helped the passengers onto the airplane and carried the passengers' bags but they did not provide food and drinks. But then in 1930, a woman called Ellen Church invented the “stewardess”.

    Ellen Church was born in 1904 on a farm in Iowa. She was a different child. She didn't want to work on a farm or marry a farmer. She wanted a more adventurous (冒险的) life. Ellen studied to be a nurse at the University of Minnesota and then got a job in a hospital. For the next few years she stayed at the hospital and at the same time took flying lessons and got her pilot's license.

    Ellen was 25 years old when she first got in touch with BAT (Boeing Air Transport). She loved flying but she understood that airlines were a man's world. Though women like Emelia Earheart were becoming famous, she realized it was impossible for a woman to have a career as a pilot. But she had another idea. Most people were afraid of flying because flying was still not a very safe way to travel. There were often delays (延误), many crashes and the bad weather made many passengers sick. Ellen thought nurses could take care of passengers during flights and BAT agreed.

    The young woman from Iowa and seven other nurses became the first air stewardesses.

    At first pilots were unhappy because they did not want stewardesses on airplanes, but passengers loved the stewardesses. In 1940 there were around 1000 of them working for different airlines. The early “stewardesses” had to be under twenty-five-year-old, single and slim. When a woman joined an airline, she had to promise not to get married or have children. It was a hard job and not well paid. They worked long hours and was paid $1 an hour.

    In the 1970s, stewardesses were unhappy in their job and airlines had to make some changes. Since the 1970s, “stewardesses” have been called flight attendants. They are well paid and work fewer hours than in the past.

    For years I wanted a flower garden. I'd spend hours thinking of different things I could plant that would look nice together.

    But then we had Matthew, and Marvin, and the twins, Alisa, and Alan, and then Helen. Five children. I was too busy raising them to grow a garden.

    Money was tight (拮据的), as well as time. Often when my children were little, one of them would want something that cost too much, and I'd have to say, "Do you see a money tree in the yard？Money doesn't grow on trees, you know."

    Finally, all five got through high school and college and were off on their own. I started thinking again about having a garden.

    Then, one spring morning, on Mother's Day, I was working in my kitchen. Suddenly, I looked out of the window and there was a new tree, planted right in my yard. I thought it must be a weeping willow (垂柳), because I saw things blowing around on all its branches. Then I put my glasses on — and I couldn't believe what I saw.

    There was a money tree in my yard!

    I went to have a look. It was true! There were dollar bills, one hundred of them, taped all over that tree. There was also a note among them, "Thank you for your time, Mom. We love you."

    Later, my children bought me tools, a sunflower stepping stone and gardening books.

    That was three years ago. My garden's now very pretty, just like I wanted. When I go out and take care of my flowers, I don't seem to miss my children as much as I once did. It feels like they're right there with me.

    I live in a city where winters are long and cold, and summers are too short. But every year now, when winter sets in, I look out of my window and think of the flowers, I'll see next spring in my little garden. I think about what my children did for me, and I get tears in my eyes— every time.

    I'm still not sure that money grows on trees. But I know love does!

    Tom is an eight-year-old student in Grade Three. He is not interested in his lessons. He spends most of his time playing basketball. At night, he doesn't sleep until very late in order to play. In the morning, he usually gets up late and hurries to school.

    Tom's father is worried about his poor schoolwork. He tries to make him work harder. One day, his father said to him, "My boy, if you get one hundred marks in the exam, I'll buy a new basketball for you." The boy was very happy to hear that.

    The next day Tom came running home. “Oh, Dad, I got one hundred." He shouted, “I got forty in English this morning and sixty in Chinese this afternoon!”
