Deep in the rainforest of Borneo, there is a special kind of tree called the “walking tree”. Its roots grow above the ground and slowly move the tree over many years. Scientists have found that some walking trees can “walk” up to two or three centimetres per year. They move towards sunlight or better soil.
A young scientist named Maya studied these trees for five years. She placed markers around several trees and measured their positions every month. She found that the trees moved faster during the rainy season when the ground was wet and soft. One tree moved nearly five centimetres in a single year.
“It’s amazing to see how living things adapt,” Maya said. “These trees don’t give up when conditions are bad. They find a way to survive.”
However, the rainforest is disappearing because of logging and farming. Many walking trees are losing their homes. Maya is now working with local people to protect the remaining forest. She believes that if people understand how special these trees are, they will help save them.
( ) 1. Why are they called “walking trees”
A. Because they have feet like animals. B. Because their roots slowly move them.
C. Because they walk to find water. D. Because they move very fast.
( ) 2. When do the trees move faster
A. In the dry season. B. In the cold season.
C. In the rainy season. D. In the windy season.
( ) 3. What is Maya doing to help the walking trees
A. She is planting more trees.
B. She is moving them to a safer place.
C. She is working with local people to protect the forest.
D. She is studying how fast they walk.
( ) 4. What is the main idea of the passage
A. Trees can walk faster than animals.
