The speed, danger and excitement of motor racing have been with us for more than a century. For over a hundred years, drivers have pushed their machines to the limit. Everyone in motor racing has a simple dream: to go faster!

    In the early days, a small number of people raced each other driving unsafe machines on ordinary roads. Today, motor racing is a huge moneymaking industry. Thousands of people are involved. Drivers, mechanics, designers, engineers and technicians work hard in the search for extra speed.

    Cars race along twisting roads or on round tracks. They race across ice and snow, as well as sandy deserts. Mud, dust, grass and steep hills are all part of today's range of racing events. Hundreds of thousands of people turn up to watch races. Millions more people watch the events on television. Top drivers are celebrities and earn huge amounts of money.

    Of course, these drivers don't get to the top overnight. Everyone has to start somewhere. Most drivers learn to race in go-carts when they are young. All drivers must learn about their cars and their engines. They must also be familiar with race rules and what to do in an emergency. Formula Ford is one of the race classes for beginners. Many top Formula I world champions like Nigel Mansell, Michael Schumacher and Mika Hakkinen began by Formula Ford racing.

    The Italian company Ferrari makes some of the world's best racing cars, all painted in its world-famous red colour. Ferrari is the most successful builder of Formula 1 cars. Ferrari has also had some famous Formula 1 champions such as Michael Schumacher. Ferrari prides itself on building the whole machine—the body as well as the engine. Some companies, such as Honda, only make engines for Formula 1 racing.

    Motor racing is expensive. Racing teams need huge amounts of money to keep their cars on the racetrack. Sponsorship is an important way of making money for racing teams. The logos of the sponsors are all over racing cars. The bigger the logo, the more the company will have to pay to the racing team.

    Mike was a good and well-trained boy. His parents loved him very much. He did everything well, but Mike had one bad habit. He ate a lot of sweets and chocolates. Those were his favorite. He just couldn't give up. His mother always told him, "Mike doesn't eat so many sweets. You will get toothaches."

    His mother used to keep all the sweets in a glass jar (罐子). One day when his mother went to the market, Mike saw that his father was asleep. So he walked carefully and slowly to the kitchen and got the sweet jar. Finally, he opened it and put his hand in narrow mouth. Mike picked a fist (拳头) full of sweets. But when he tried to pull his hand out, it got stuck (卡) in the jar.

    Mike's father was awake and watching. He said to Mike, "You have picked up too many sweets in your fist. It's more than your little hand can keep. Your fist cannot come out of the jar. Let go off the sweets and pick only one sweet in your two fingers and you can pull your hand out easily. Always take as much as you can control."

    Mike pulled out his hand from the jar easily and he learned a lesson for his life, too.

    Sleep plays an important role in brain (大脑) development. Children should get enough sleep.

    {#blank#}1{#/blank#} A study says that because of being short of sleep, it is much harder for children to do something carefully. And also they become forgetful and easy to make mistakes. Another study shows that the right amount of night—time sleep is just as important for children's development as healthy eating and taking exercise.

    {#blank#}2{#/blank#} In general a younger child needs more sleep than an older one. Children at the age of 5-11 will need 10-12 hours of sleep a night while children at the age of more than 11 will need less hours.

    In fact, many parents don't know how to help their children get enough sleep. Here is something you can do. For children at the age of 5-11, a 30-40 minutes' routine (常规) before sleep is helpful.{#blank#}3{#/blank#} In the activities, children relax and enjoy themselves a lot, and they will go to sleep more easily.

    Children at the age of more than II may go to bed late in the evening, talking with friends online, playing games or watching TV. {#blank#}4{#/blank#}  And even they will be tired during the day.
