With more and more cars on the road, the traffic jam will happen. How do we see it and how can we solve the problem?

    We know that the traffic jam(堵塞)happens in many places, especially in big cities. What are reasons for the problem? On one hand, some people think that they should have a car when they have enough money, and then it's easy to go out and they can feel comfortable. On the other hand, a growing number of people hope to use their cars to show off (炫耀). What's more, years of research has shown that one of other reasons for the traffic jam is the driving habit. For example, many young people enjoy driving very fast, so they can feel excited. At last, most of them hardly care about the speed rules.

    Many governments are working at how to make the traffic better. In my opinion, firstly, the governments should educate those people who have cars or plan to buy cars. The governments must make them know that the traffic jam is very serious, and set up a much more perfect traffic system (体系)to solve the traffic pressure.

Nature is amazing! Take a close look at the world of insects, and you'll discover many unbelievable things. Consider butterflies (蝴蝶), for example. They have beautiful wings and magical flying skills. On summer days, you always see them flying freely over flower gardens and wild fields.

But did you know how butterflies become the flying insects? It is one of the wonders of nature. In the beginning, the mother lays a small and colourful egg on a leaf or stem of a plant. It is hard to believe that the egg will become something completely different in a few days. It becomes a walking insect. This insect is called a caterpillar. It now has legs, eyes and a large body. A new life begins. The caterpillar can eat, walk and see. But it is still not a butterfly.

Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket (保护层) and goes to sleep. This is known as the "pupa (蛹)" stage. After some time, the blanket breaks and a wet butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the beautiful butterfly spreads (张开) its wings and flies away. After a few weeks, this butterfly lays her eggs, and the cycle (循环) begins all over again.

This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things.

Around the world，many wild（野生的）animals are in dangerof extinction（灭绝）because they have no place. to live in. Endangered （濒危的） wild animals live all over the world and you may find some in your hometown. Here are some steps for protecting endangered animals. 

Step 1:Find out what, animals are in danger. Spend some, time. learning about animals and what their favorite places are. 

Step2： Do something for nature reserves（自然保护区）. Nature reserves are good places to help protect endangered animals. You can give some money to nature reserves or spend your time helping the nature reserves to protect endangered animals. 

Step 3: Never buy anything that are made from endangered animals. Don't do harm to endangered animals or their living places. Instead, we should try our bestto protect them. 

Step 4： Join an endangered animal protection organization（组织）. You can save animals through these organizations by planting more trees and calling for more people to protect animals. 

If everyone works hard to protect endangered animals, we'll get a more beautiful world. Let's take actions from now on!
