In most situations, light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution. It prevents our view of some of life’s most striking sights: stars, planets, and even galaxies.
“When I was a little boy, I loved the night sky. I remember looking up and the sky was filled with stars. I became an astronomer because I was amazed by their beauty,” says Robert gent, “Now in most big cities kids can’t see the stars like I did.”
Normally, about 2,500 individual stars are visible to the naked eye without using any special equipment. But because of light pollution, you actually see just 200 to 300 and fewer than a dozen from some cities. Only one in three Americans can see our own galaxy (星系) with the naked eye. Those people live far away from the lights of big cities, office building, and shopping malls.
Fortunately, there’s an inexpensive and useful way. If we shine lights down at the ground instead of up into the sky, and use lower brightness levels, we can save big amounts of energy and keep the beauty of the night skies. Many cities and towns have passed laws limiting lights at night, making sure enough shine for safety without creating much light pollution.
Light pollution affects more than our view of the heavens and can harm wildlife. Migrating (迁移) birds sometimes fly over cities and become confused by the brightness, flying in circles until they drop from exhaustion. Sea turtles need dark beaches for nesting and won’t approach bright lights. Too much light at night may even affect human health. For all these reasons, researchers are working on ways to use light only when and where they are truly needed. Everyone deserves to look up at the sky.

High school students are some of the busiest people in the world. To get the most from all you do, you must be in control of your time. Otherwise decision that affect how well you play the game, what position you play and when you get to play will be decided for you. Your success in high school depends on your use of time. Here are some important things to remember.
·Begin each term by filling in a master plan. First fill in things you must do (classes, work, practice, etc. that you can’t change.) Then find the most effective use for these times.

·Use daylight hours to study whenever possible. For most people for every hour of study done in daylight hours, it will take them one and a half hours to do the same task at night.
·Take breaks. Don’t plan marathon study time. Have a short rest before you study again.

·If possible, plan study time with a partner. Choose your partner wisely however. Make sure you study, not socialize.
·Do the most difficult tasks for times when you are active. (For example, when you’re energetic, it will become easier to solve maths questions; when you’re tired, it will be impossible!)
