阅读理解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!
