You always have to understand what you are good at, and what you are not good at. Or if you are interested in something you always have to master it first.

When I was ten, I came over to my cousin’s house, and that was pain because he lived in New York and I lived in Miami. So I came over every summer break by myself, of course I had my parents’ permission to go that far.

One day, We decided to head to the forest. I was looking forward to this trip because I knew that my cousin was an expert on tree climbing while I was not. So, as we walked closer and closer to the forest, I became jealous because I did not possess the ability to climb trees. When he started climbing a tree I was upset but I joined him hoping not to break my neck. Last Summer break he invited me to his house. I was afraid of climbing to the tree so I gave up. But this time I tried climbing the tree. While I was climbing I was so scared like I was about to die at any moment. But when I was about to climb on the other branch I lost my balance. Luckily I got hold on one of the bottom branches. My cousin suddenly started climbing down and tried to help me. After he put me on the ground, he ran to get some help. The pain was just killing me, I lost a lot of blood and I knew that I have to be awake to survive.

We always read reports about costs of oil going up and we will think this is our most valuable material. However, water is the most valuable resource(資源). People in the Middle East are more worried about this than oil. Maybe the next war will be about water.

In the future, to control the quality and quantity(數(shù)量), you will use different water for different usages. The water used to wash your car, water your flowers or wash your clothes doesn’t need to be as clean as the water you drink.

One in five people live in countries without enough fresh water and in 25 years, the number is believed to be one in every three people. Our world population is increasing. What do you suppose this will suggest for us in the future? Population control?

Britain and France have already taken measures to successfully improve their water industries. All the water services in Britain have been provided by private(私有的) companies since 1991. Since then, improvement has been made in the rules for their water quality and pricing.
