It’s International Whale Shark Day on August 30th, so let’s find out about these fantastic fish. Whale sharks are the world’s largest fish. It can be 12 meters long, as big as a bus! They live in tropical (热带的) and warm seas around the world. Every shark’s spots and stripes are different from each other. They can help scientists know who they are. Although they are really huge, whale sharks can’t bite or chew (咬和嚼)! They just open their mouth widely when swimming, and let lots of water come through their gills (鳃) to catch small shrimp and fish for food. Being slow swimmers, whale sharks hardly travel more than 5 kilometers per hour, but they sometimes go on great migrations (迁徙) that are hundreds of kilometers long. Surprisingly, they can live to be more than 100 years old. Wow!

There are many kinds of amazing animals in the world. Have you ever watched one of them Canada geese(雁)? They can teach us a lesson about teamwork.

In autumn, Canada geese have to fly to the warm south to get away from Canada’s cold winter. When they leave the ground and rise into the air, they fly in no order. Then they quickly form a V shape, with one bird leading the group.

The V shape allows Canada geese to save energy(精力). The head bird moves its wings(翅膀) up and down. The resulting force of the air helps lift the next bird. Each bird will do so until they get to the southern part. The bird at the head of the group has the hardest job. When it gets tired, another bird moves to the front and takes its place(代替它). By sharing this job, the group can travel great distances.

Canada geese flying in a V shape can fly seventy percent farther without having a rest than the birds flying alone.

During the long flying journey, Canada geese communicate with one another. They honk(鸣叫) to encourage the birds up front to keep up the speed. They also cheer one another up while working toward the same destination(目的地).

What have we learned from the lovely Canada geese’s experience and skills? Work together! Whether in our personal lives or our jobs, we need the spirit of teamwork!

There are two mice. They are called John and Mike. They are good friends. One mouse lives in the country, the other mouse lives in the city. On a sunny day, they met in the street.

Mike: Hi, John! Have a look at my house in the country. I’m sure you can enjoy yourself.

John: I’d love to. But I hear that the food is not delicious, and your house is not good. Is that true?

Mike: No, that’s not true. Go and see!

Then John goes to the countryside with Mike.

John: Why do you live in a hole in the field? You should come and live in the city, You would live in a nice house made of stone. You can have better food to eat. You must come and see me at my house in the city.

Mike: Thanks! Maybe you are right. I’ll visit your house one day.

Several days later, Mike went to John’s house in the city. The house was big and beautiful. They sat in the living room, having a big dinner comfortably. Suddenly, there was a big noise.

John: Run! Run! The cat is coming!

Mike: Oh, no! It’s terrible! Both the house and the food are nice, but I do not like living in the city. I enjoy living in my hole in the field, for it is better to be poor but happy than to be rich but afraid.

John: But each day is exciting, right?
