    Many of us enjoy watching animals in the world. But do you know they can teach us?

    Geese(雁), for example, teach a very good lesson about 1. In the fall, Canada geese fly to the warm south to 2 Canada's cold winter. They lift off in no order. Yet 3 they form a V shape, with one bird leading the group.

    This V shape allows geese to 4 energy. When the front bird moves its wings up and down, the resulting force of the air lifts the next one. This continues down the line. The bird 5 has the hardest job. When it gets6 , it moves behind, and another bird moves into the lead. By sharing the role, the group can travel great distances. Geese flying in a V shape can fly 70 per cent farther without 7 than birds flying alone. During the long flying journey, geese communicate with one another. They honk(鸣叫) to 8 the birds up front to keep up the speed. They also cheer each other up 9 working toward a common goal.

    What have we learned from the lovely geese's experience and skills?

    10 together! Whether it is our personal lives or our jobs, we need other people. We need the spirit of teamwork!

    There are many wetlands in China and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home to many different kinds of animals. The world's largest Milu Deer Nature Reserve is in them. More than 700 Milu deer live freely there. There are not many red- crowned cranes in the world, but every winter you can see some in the Red-crowned Crane Nature Reserve in the Yellow Sea Wetlands.

    The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine too. They are really good places for wildlife. Offering(提供) food and home to some special kinds of animals is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and less space for wildlife.

    Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.

    Bridges are built for many reasons. Some bridges are built so that cars can cross over rivers.        are made for trains to use.  In Washington State, there is a very        (usual) bridge. It was built for squirrels(松鼠). The town of Longview has a very busy street. Many cars pass        every day. When squirrels tried to cross the street, they       (kill).  Amos Peters wanted         (protect) these small and lovely animals, so he built a bridge for them--one that would let them pass above the traffic.

    The bridge        (be) a symbol of the town for over 40 years since then. And every Christmas, the local people add a small Christmas tree to the centre of the bridge.        lovely!

    A few years ago, the local people created        squirrel festival and they raised money        (build) two more bridges for these lovely animals. For years, because of the bridges, the squirrels in the town have been able to cross        (safe) from one side of the street to the other.
