The three most wonderful train journeys provide the natural beauty of China. Read on to see which line you want to start your journey with.

There’s nothing quite like falling sound asleep after a full day of work. Like people, animals need to rest after working hard. Some animals sleep in water. Others dig holes under the ground. Some even sleep high in trees or under leaves. But they all find a way to rest.

Some animals in the sea sleep in strange ways. Fish sleep with their eyes open. They seem to look ahead far into the sea while they rest. Sea otters sometimes sleep in beds of the plants that grow in the sea. This keeps them from moving away. Parrot fish blow something from their mouths when they are ready to sleep. Then a bubble (气泡) will be formed around them. The bubble protects them from harm while they sleep.

Some animals sleep under the ground. Chipmunks (花栗鼠) sleep curled up (蜷缩) in a ball. Their beds are made of leaves and grass. In winter, they sleep for two weeks and wake up to eat the stored food. Then they go back to sleep for another two weeks before waking up again. Some desert frogs dig underground holes during the hot, dry season. A frog may stay in its hole for months.

High above the ground, monkeys find leafy places in trees each evening before they sleep. The tall trees help to keep monkeys safe during the night. Some insects even sleep under the leaf that will be their next meal. A bee may climb down into a flower to rest. When it climbs out the next morning, it is rested and ready for work.

Energy is the ability to do work. Solar energy (太阳能) comes from the Sun. There is also energy that comes from wind and water.

But do you know that energy can come from people, too? When you pedal (踩踏板) a bike, you produce energy. You use your legs to push the pedals. Your energy is transferred (转移) to the bike. That makes the bike move.

Now imagine riding your bike to create enough power to run a computer. Some students at one school did just that! They jumped on bikes connected to generators (发电机) and pedaled in place. Soon they were producing electricity. This energy is needed to run their computers.

Here is how bicycle-powered energy works. When a student pedals the bike, the back wheel spins. The wheel spins the generator. The generator produces electricity. As long as a student pedals the bicycle, electricity moves through the generator. The electricity can be used right away. This energy can also be stored(存储)and used later.

People use bicycle-powered energy to run small devices (设备) such as small televisions and fans. They often use less than 100 watts (瓦特) per hour. However, it would be a mistake to use pedal power to run a fridge. This large machine often uses more than 700 watts per hour. The electricity for these machines comes from power lines overhead or underground.

Pedal power can be seen in schools, gyms, and homes. What a fun way to provide electricity!

    40     In the daytime, people can enjoy the performances such as a dragon lantern dance, a lion dance, a Yangge dance and beating drums. At night, except for the beautiful lanterns, fireworks（烟花）form a beautiful scene. Some local governments usually organize a fireworks party.

People enjoy themselves during the Lantern Festival.
