Do you know the whales in the sea? There are many relatives(亲属) in the whale family and they always live together with whales.
Few people know dolphins(海豚) are part of the whale family. Dolphins are not fish. They are mammals(哺乳动物). They breathe air, and they have babies and feed them with milk. Dolphins are famous for their wonderful shows. They can jump high out of the water and show turns in the air. These jumps give the dolphins time to breathe.
Porpoises(鼠海豚) are also in the whale family and are quite like dolphins. But they are different in the size and shape of the mouth. The dolphin's mouth is long and thin, but the porpoise's is short and thick. Dolphins are also more talkative than porpoises. Dolphins make sounds to talk with each other under water. But porpoises do not do this. Both of them are smart and friendly to humans.
Not all the members of the whale family are friendly. Big whales are much easier to be angry than smaller dolphins or porpoises. An angry whale can be dangerous. Perhaps this helped to create the story of Moby Dick that sank (使下沉) a ship and made all the people on it die in the sea.

There are so many traffic accidents now. Many people are killed or hurt everyday on roads. It's becoming a more and more serious problem. Why?
Sometimes drivers drive too fast or don't drive carefully enough. They talk or answer the cellphone during the driving. Some drivers drive against the red lights. What's worse(更糟的是), some drive on the road after drinking alcohol(酒) too much. Now ①“No driving after drinking; No drinking before driving” is very popular.
Many people think the main reason of traffic accidents are from drivers. Is it true?
A survey(调查) shows that the pedestrians(行 人) can also cause the traffic accidents. Some of them often walk in the roads instead of on the walkways. They get into or out of cars in the middle of the road. They walk or run in front of the fast cars. They even walk across the roads against the red lights.
Some people think that too many people cause too many accidents. However, the traffic in Tokyo shows that it is wrong. ② Tokyo(东 京) is one of the world's largest and busiest cities. The police there are strict, the drivers there are careful, the pedestrians follow the traffic rules. There are very few accidents happening there.
