B
Imagine you are living in a moving house. Inside the house, there is a kitchen, a bathroom and a bedroom. Although they are much smaller than those at your home, they are easy for you to use.
Now you can see these moving houses on the road in China. They are called recreational vehicles (RVs). People call them "houses on roads". When it's holiday time, the whole family will get into the small home and hit the road for a trip across the country.
Compared to a real house, this "home" on the road is useful for a family. The best thing is that you can do everything you like freely. You can drive as long as you like without worrying about finding hotels and restaurants. Or you can just stop somewhere nice and stay for a few weeks. You may also meet other families that are on road trips. Together, you put up your tents. It's camping time with lots of talk and laughter.
However, RVs are not always convenient. They can sometimes break down and don't work. You have to spend time fixing them. But many people still like this kind of vehicle because they can go anywhere they want whenever they want.

The monkey and the dolphin
One day long ago, some sailors(水手) set out to sea in their sailing ship. One of them brought his pet monkey along for the long journey.
When they were far out at sea, a terrible storm overturned (推翻) their ship. Everyone fell into the sea, and the monkey was sure that he would drown (溺死). Suddenly a dolphin appeared and picked him up.
They soon reached the island(岛) and the monkey came down from the dolphin's back. The dolphin asked the monkey, "Do you know this place?"
The monkey replied, "Yes, I do. In fact, the king of the island is my best friend. Do you know that I am actually a prince(王子)?"
Knowing that no one lived on the island, the dolphin said, "Well, well, so you are a prince! Now you can be a king!"
The monkey asked, "How can I be a king?"
As the dolphin started swimming away, he answered, "That is easy. As you are the only creature(生物) on this island, you will naturally(自然地) be the king!"
Those who lie and boast(自吹自擂) may end up in trouble.
