We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flower exhibition. After visiting Perth we spent a day in the countryside. We sat down and had a rest near a path(小路) at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quickly as we could. There were about three hundred sheep coming towards us down the path.

The one-child policy has been carried out for about 20 years .Most Chinese families have only one child. By the year 2008,the number of only children in China had already been 330 million ,which was about the population of the United States .In the next twenty years ,the only-child generation (一代人) will become the main builders of our society .No one knows how much he or she will change the world .

Only children in families often receive the best care, sometimes ,even get a lot of indulgence .Parents always try their best to satisfy their children’s needs .Those children, who are called “little emperors” ,are in danger of too much love .

However these kids often fell lonely because neither their parents nor their classmates can take the place of a brother or a sister.

It seems that only children are still not ready to do their duty .some elder only children have already graduated from college .But they still depend on their parents .They need a longer time to change for their jobs, because they were brought up in a safe environment. When their parents get older, a couple of only children will have four parents and even more grandparents to look after. It will surely be the biggest problem if they don’t well prepare to face it.

 How____ is the population of the world?  

The population of the Earth is growing faster. It is important that we look after the Earth. We need it! The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.

In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.

         Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.

         So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!
