On the day of the interview, I got up at 6:00 in the morning. I got to the interview place without having1. l was the 24th interviewee(应聘者) and the 22nd was a short ordinary- looking girl. I greeted her by2my head. I asked her where she graduated. She told me in a low3, "I graduated from a junior college， the only one without getting a bachelor' s degree(学士学位) among the 50 interviewees.

    After a while, a worker came in and8me a bottle of milk and a piece of bread. It was certain that they were bought by the girl. I felt9all over my heart because I hadn't imagined she would be so nice to help me- her rival(竞争对手).

Luckily, I got the job. The first day I went to work, I was10to see the girl there. She also got the job. Later I asked her why she got the job. She said11a smile, "That day when I bought you the12, an interviewer went to the toilet with papers in hands. He asked me13I could help him to copy those papers while he was in the toilet. I helped him. After I came back to him, he asked me why I took the food in hands. I told him the14. Then I got the job." At that moment, I came to know that when the girl helped me and the interviewer, she also helped15.

    Air pollution influences our health in many ways. No air means death. Though we can't see it, there is air around us. Air is everywhere and it gives a life to every living things. But bad air makes people ill. In the city, there are a great many people and there are too many cars running on the road. The cars send out bad gases (气体). There are many factories too. From the chimneys (烟卤) of these factories, we get the smoke usually in black colour. Every day we breathe it in and out. This makes us feel sick. When people talk about air pollution, they are usually thinking about outdoor air pollution. But a lot of air pollution comes from indoor activities such as smoking and cooking. Indoor air pollution can hurt people's eyes, noses and throats. So air pollution, both indoor and outdoor, can also lead to lung cancer (肺癌) and heart disease.

    Everyone should help fight against pollution. In order to keep us healthy, we have to go out to the countryside to breathe more fresh air. Or we can climb up hills to get more fresh air.

Taking Root.

How many kinds of plants are there in the world? Lucy Braun wondered that as a child. She showed great interest in plants at a young age. She often had energetic walks with her family through the nearby woods. Some plants and wildflowers seemed to shout at her with their wildcolours. Others hid behind rocks.

Lucy looked at the shapes of leaves as she walked in the woods. She kept a record of what she saw. She also learnt to draw what she saw. Then she could compare all kinds of plants. Later, Lucy grew more and more interested in botany, the study of plants.

Branching Out

At university, Lucy took classes in geology, or the study of rocks and minerals. Her work with geologists changed how she looked at the natural world. She continued her studies in botany as well. Lucy also took classes in ecology (生态学). Lucy believed that plant life in some are as was able to move to other places over time.

In Full Bloom

In 1917, Lucy began to teach botany at a university. She lived in a house near the woods. Lucy collected plants from all around the country. She took many photos of them, too. Colour photography was still new then. Because of that, people enjoyed her lessons and photos a lot.

The    ▲     of Labour (劳动)

Later in her life, Lucy wrote many field guides. In 1950, she published her most important guide. It describes the plants in the forests across the country. Ecologists still use it to study changes in the forests over time.

Today, Lucy has a few plants named after her. One of them is Lucy Braun's snakeroot, which is now in danger. Lucy's work in the protection of nature may help prevent its disappearance.

Lucy Braun lived to be 81. In her years as a botanist, Lucy collected nearly 12,000 plants!

What's your dream? What do you want to be when you grow up? Three girls shared their thoughts with us.
