We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live a green life.
Remember these three words: reduce, reuse and recycle.
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle means “change things into something else”. Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

Teeth are important. Strong, healthy teeth help you chew foods that help you grow. They help you speak clearly. And, they help you look your best. Here are some advice for you to take care of your teeth.
● Brush your teeth the right way.
Brush your teeth at least twice a day after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks（快餐）, too.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
Brush all your teeth, not just the front ones. Spend time brushing teeth along the sides and back of your mouth. Brush away from your gums（齒齦）, too.
Spend at least three minutes each time you brush. Play a song you like to help pass the time.
Get a new toothbrush every three months. When you buy your tooth brush, be sure it has soft bristles（鬃毛）.
● Learn how to floss your teeth.
Flossing is a very important way to keep your teeth healthy. Food may hide in places where a toothbrush cannot get to, like the space between the teeth. Flossing can help get rid of it. Carefully move the floss between two teeth, up and down. You need to floss your teeth at least once a day.
● Have good eating habits.
You need to be careful about what you eat and drink. Eating sugar is a major cause of tooth decay（腐朽）. Eating sugar before you go to bed can make things even worse. Eat lots of fruit and vegetables and drink water instead of soda.

What makes 15,000 men and women run for hours, and what makes them run through the streets on a cold day without coats? I was one of those runners.  The race is called marathon (馬拉松).
I had never run more than eight miles before, and here I was training.  Since the race is in April, I had to run throughout the winter, and in Boston, winters are cold. For most people, just putting on their shirts, sweaters, jackets, and hats is exercise enough. I found myself out on the dark streets, running along ice sidewalks (人行道). Even in gloves, my fingers got so cold that they looked like red carrots. My nose didn’t get warm until lunchtime !
Finally, the big day arrived. The weather was cold, with ice and rain. Bang! The gun sounded, and we started. I didn’t go anywhere at first because I was standing behind so many people. I had to wait for them to move.
At first, the running was easy.  The other runners just seemed to pull me along. Somewhere around the 20-mile mark I even said to myself, "This is nothing, why did I train so hard?"
Then I hit "the wall". "The wall" is what marathon runners call the special point. I knew my body reached the point and I thought I couldn’t go any more. I was out of breath and my legs turned into pieces of wood.  I was almost falling down.  I can’t remember anything about the last five miles of the race.
I kept running though. At last, I heard a voice at the finishing line.
"You look good," my friend Ted said. "How did it feel?"
"Wonderful !" I replied.
For everything, if you devote yourself into it, there will be a way. I finished the race, at least, in my heart, I was the winner.
小題1:Which one best describes the weather on the race day?
A．Cold and rainy.B．Cold and sunny.C．Dry and cloudy.D．Wet and foggy.
小題2: How did the writer feel about the race during the first 20 miles?
A．Difficult.B．Boring.C．Easy.D．Interesting.
小題3: According to the article, what must someone do to prepare for a marathon?
A．One must eat certain food and get plenty of sleep.
B．One must be willing to eat, sleep, and train twenty-four hours a day.
C．One must run along ice sidewalks every day.
D．One must be willing to train a lot and doesn’t give up easily.
小題4:Then I hit "the wall". What do you think "hit the wall" means here?
A．撞擊墻壁B．到達極限C．抵達終點D．中途加速
