Last September, my family visited a turtle centre in Kemaman, Malaysia. It is famous for its clear beach and it is home to Green and Hawksbill turtles. The centre saves them by keeping their eggs safe and helping the baby turtles return to the sea safely.
When we arrived at the centre, we met the workers. One of them told us a sad story. He found a nest with about 100 turtle eggs in it, but they didn't hatch(孵化) because of a deadly fungus. Sadly, there is also another danger to the turtle eggs from the ghost crabs because the ghost crabs love to eat turtle eggs. Besides, some eggs don't develop properly. When such an egg hatches, the turtle even has two heads! These turtles have problems living in the world.
Later, the worker showed us the turtle eggs in the hatchery. That day, we saw some baby turtles hatch from their eggs. It was amazing to watch them break out of their shells and start crawling(爬).
As night fell, the worker took the baby turtles to the beach. They used the red lights to help us see the turtles better. Turtles can't see the red light very well. So it wouldn't affect them very much. The baby turtles moved quickly as they headed into the dark sea. Welcome to the start of your long journey into the wild, little turtles!

①Do you do sports every day? Which sports do you like best? Or do you enjoy taking a walk just like me?
②Walking is an easy exercise and a good way to improve health. During this exercise, your body uses fat for energy. It is a good way to burn calories and control your weight.

What's more, studies have shown that walking can strengthen people's brains. Walking can make blood flow to the brain faster. This helps people remember and learn things better. The exercise also gives teenagers stronger bodies.
