We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily: reduce, reuse and recycle.

Reduce

Reduce means “use less”. Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish. Turn off the lights when you do not need them. Before you buy something new, think whether it is really necessary because maybe the old one is just as good!

Reuse

Reuse means “use again”. Use things for as long as possible. Look after them so that they will last. Repair them if possible. Do not throw them away and buy new ones. Do not use paper cups or paper bags.

Recycle

Recycle means “change things into something else to be reused”. We throw tons of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber（橡胶）.Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.

Sometimes the world may feel like an unhappy place. However, you can make a difference. If you make even a person smile today, you can help make this world a better place. Here is a list of ideas to help you.

In this age where everything is sent by email, it is a shock to receive a letter through the post. Writing a few words on paper to a friend is an easy way to make one smile. Even a postcard with a couple of sentences could really make someone’s day—all for the price of a stamp!

Volunteering is one of the nicest things you can do. It requires（需要）some time and research to find the perfect project before volunteering. Whether you volunteer at your local youth group or take dogs from the shelters for a walk, the simple fact that you are giving up your time to help someone else is unbelievable. There are so many chances, so you are sure to find one that is right for you. And it doesn’t necessarily have to take up all your time—it could be once a week or a couple of times a year.

Whether you’re creative or not, taking time to make something for someone else shows how much you appreciate（感激）them. Even if you think you are not creative, the receiver will feel lucky to get such a special gift that you put your time into. Some ideas could include a card, painting, drawing, song, poem or cake!

It can be anyone—a family member or a friend. You don’t even have to say “I love you”. Perhaps you can tell friend that you appreciate all they are to you, or remind your mum that you love her. Sometimes, in our busy lives, we forget to take a moment to tell people what they mean to us.

Asking people to a party is an art. You must think about what kind of party you’re going to have first. If it is a small party, you can just give a call to your friends and ask them to the party. You can even e-mail them or just leave a message for them.

Now, calling someone is an art, too. First, give a call to your friends, and then begin the talk by asking them about their life and family. Then ask them about their schedules (日程表) on the day of the party. If they say they are free, you can ask them to the party directly (直接地). If they are not free, then ask him to try to find time for your party.

If you’re going to have a big party, and need to ask lots of people to your party, you must decide how many people you want at your party. Then you can write a list of them and send them beautiful invitation cards, because you may not have so much time to give them a call each. You must send the cards a few days before the party so that they can have enough time to prepare for it.
