We all know that regular physical exercise is good for a girl’s body, mind, and spirit ．Here are a few:

       Research shows that girls who play sports do better in school and are more likely to graduate than those who don’t．Exercise improves learning, memory, and concentration, which can give active girls an advantage when it comes to the classroom．

       Some benefits of sports are clear — like improving fitness and maintaining a healthy weight．Girls who play sports are also less likely to smoke．But girls who play sports in school also continue to see the benefits later in life, with reduced chances of getting breast cancer．Sure, you can get these benefits from any type of exercise．

       Working with coaches, trainers, and teammates to win games and achieve goals is great practice for the real world, where teamwork is a key to success．For years, boys learned these skills through sports while girls sat on the sidelines．But as more and more women hit the field, they’re joining boys in both the classroom and the boardroom．

       Girls involved in sports feel better about themselves, both physically and socially．Practicing, improving skills, and gradually achieving goals help to build confidence．

       Pressure is a big part of life．Playing sports can help you deal with it, since exercise is a natural mood lifter and a great way to reduce pressure．Plus, when you are on a team, you have friends who support you both on and off the field．

       Other benefits of doing sports include getting in shape, and making new friends．

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.

Adaptable glasses

Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透镜）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.

The wind-up radio

When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (发电机) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.

The Dyson cleaner

In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.

The Zapata fly-board

Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200.

So keep dreaming and inventing. One day you might get it right.
