    John is an American boy. His family is in China now. John likes chocolates (巧克力) very much. But his mother doesn't give him any. They are not good for him, she thinks. But John has a very nice grandfather. The old man loves him very much, and sometimes he buys John some chocolates. Then his mother lets John eat them. She wants to make the old man happy. One Sunday evening John says in his room, "Please, God. Make them give me a big box of chocolates tomorrow. It's my birthday." His mother says, "God can't hear you, my boy." "I know, but my grandfather is in the next room. He can hear."

    It was a rainy night in New Orleans, US. At a bus station, I watched a young girl cry as her baggage(行李) was taken down. It seemed she'd lost her ticket. She begged the bus driver not to leave her behind.

    “Losing your ticket is like losing money,” the bus driver said, and left her in the rain.

    But then an old man stood up and blocked the driver's way. “How can you leave that girl out there? You know she had a ticket. You can't just leave her here. You can't leave her in a city where she doesn't have a friend. You will meet your schedule(日程安排), but she might meet her end.”

    The driver showed no sign that he'd heard or even cared about the young girl's problem, or how her travels went.

    So the old gentleman said: “I'll pay for her ticket. I'll give her a little money to help her on her way.”

    He went and bought a ticket for the girl. “How can I repay the kindness you've shown tonight?” she asked. “We're strangers who won't meet again. A mere ‘thank you' doesn't seem right.”

    The old man said: “What goes around comes around. I've learned this with time. What you give, you always get back. Always be helpful to others and give what you can spare(分让).”

    Andrew Holleman, a 12-year-old boy, loved playing in the open land near his home. The land was wet and forested, and made a home for birds, other animals and many different plants.

    It made the perfect place for him to study and get to know nature. He had seen some red-tail hawks, red foxes, wood turtles and other animals. He also found special native flowers.

    Suddenly it was reported that the "empty" land would be improved by a lot of houses on it. The plants would be removed, the animals would run away and most would probably die. Then the wet soil would be covered with extra grounds.

    When he heard about the news, he was not happy. He was very worried that the land and water would be polluted. Andrew wrote down clearly all the research he had done about the area, and how the houses would affect(影响)the local environment. He sent letters to members of local government and television reporters. He also called on his neighbors to oppose the building of the houses.

    Although he was only 12 years old, he had the courage and wisdom of a person much older.

    Andrew's teachers described him as a gentle, shy and active. His classmates also admired how much he knew about local animals and plants, and the environment. Each day after school, Andrew went door-to-door, to ask the people to sign(签字), who did not want the houses to be built. In only one month, he got the signatures of 250 people.

    In the end, the land remained a safe place for birds, animals and plants that belonged there.

    Andrew won many prizes for his brave and great work to stop the houses being built, and he helped save the environment.

One evening, I invited a group of my friends to my house, {#blank#}1{#/blank#}them that I need their help for a study and it would take only a few minutes. 

They all sat down nervously (紧张地) when they saw a recorder （录音器）in my{#blank#}2{#/blank#}. Seeing that, I told a "lie" that there was only one small task (任务) for them—ｔhat was just to count from one to twenty. 

Then each of them in turn counted from one to twenty. {#blank#}3{#/blank#}it was over, I pretended (假装) to turn the recorder off and brought some drinks for them. Enjoying the drinks, we started to talk and joke{#blank#}4{#/blank#}.

Well, my{#blank#}5{#/blank#} task began—to record each one's speech （发言）for a study. 

It happens every spring. Flowers come out everywhere on the same day. But how do plants "know" when to flower?

For years, it has been a difficult question for scientists. But a US research group may have finally answered it—the secret lies in a protein(蛋白质)called FKF1. This helps plants to know when the days become long and when they get short. Then they can tell the seasons(季节)are changing.

Researchers found the FKF1 protein when they were studying a plant called Arabidopsis. It is sensitive(敏感的)to sunlight, and can be made active by sunlight.

Plants produce this protein every day in the late afternoon all year. If there is no light at this time, for example, in winter when the sun goes down early, the protein won't be active. But when spring comes and the days get longer, the FKF1 protein can be made active by day light and the plants "know" it is time to flower. " If there is light in the late afternoon, plants will know that the days are getting longer and that it is the best time for flowers to come out,"explained Takato Imaizumi, leader of study. But when conditions are poor for growing, such as during autumn or winter when the weather is cold and days are short, plants won' t flower.

Although researchers have only studied how the FKF1 protein works in the Arabidopsis, they believe that it is the same with many other plants, including crops such as rice and wheat.

"If we can control when flowers come out, we might be able to increase crop production," Imaizumi said.
