二 阅读短文，完成任务。
We live on Earth. Earth is our home. We can help Earth in many useful ways. Three great ways are: Reduce! Reuse! Recycle! We throw away(扔掉) too many things and make too much rubbish(垃圾). Now let's stop and think: Can we reduce them? Can we reuse them? Can we recycle them?

Reduce!
• Reduce paper use. Always use both sides of the paper for writing and drawing—we need to save trees!
• Reduce the use of plastic bags. 1.
• Reduce energy use. Walk or ride a bike often.
Reuse!
• Don't throw away old bottles and cans. Wash them if they are dirty, and use them again.
• 2. Give them to people in need.

• Don't throw away coloured paper from gifts. Be careful to open gifts and use the paper again!
Recycle!
• We make new bottles and jars from old glass.
• 3.
• Don't throw away anything that you can recycle. If you throw some things, use the right bin!
It's important to take care of "our home". When we use "3R" rules, we are helping Earth keep green and healthy.
