What isthe hardest sport in the world? Some people say it's boxing (拳击), because boxing is dangerousand boxers have to be strong and fast. Other people say the hardest sport issoccer.

    However,most people say the hardest sport is the triathlon (三项全能运动). A triathlon is a race thatincludes three sports. First, racers swim. After that they ride bicycles andfinally they run. In the most common triathlon, racers swim 1.5kilometres, bike40 kilometres, and run 10 kilometres. The winner is the person who finishes therace first.

    There isanother kind of triathlon too. It is called the "Ironman Triathlon (铁人三项)". This triathlon is muchlonger. People who finish this triathlon are called "ironmen" or"ironwomen". This is because these people are so strong that theirbodies are just like iron (铁).

    In thepast, there were other races including three sports. However, they didn't usethe word "triathlon". That word was first used to describe a race inCalifornia in 1974.

    Triathlonracers have to train very hard for their races. Many of them swim and run. Alot of people also do things like yoga (瑜伽). They have many different ways to prepare, but they all have thesame goal. They want to be in perfect shape.

    To be anironman or an ironwoman, you have to be strong and smart. You should know howto save energy during the race.

"Early to bed and early to rise makes a man healthy, wealthy and wise." This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we will be healthy. We will also be rich and clever. 

Is this true? Perhaps it is. The body must have enough sleep. Children of your age need eight hours' sleep every night. If you go to bed late, you can't have enough sleep. Then you can't think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!

Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong. 

Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!

Our bodies also need air to breathe. Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.

Our school will hold an English Week. We can communicate with others about the English learning methods there. What's more, we're sure they will help you learn English more easily and with more fun!

Happiness is important for everyone. Most people want to be happy, but few know how to find happiness. Money and {#blank#}1{#/blank#} alone do not bring lasting happiness. Happiness {#blank#}2{#/blank#} on ourselves.

The {#blank#}3{#/blank#} secret of happiness is to enjoy the simple things in life. You should enjoy life's simple pleasure such as reading a good book, listening to your favorite music or spending time with close friends. People who have several good friends tend to live {#blank#}4{#/blank#} and happier fives. I

The second secret to {#blank#}5{#/blank#} a happy life is to be active. Many people experience this by dancing, or playing a sport. You can forget about your problems, and only think about the activity.

Finally, many people find happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. So if you want to feel happier, just try to help others.
