How to Be a Greener Person?

What does it mean to be a greener person? "Green" is more than just a 1   It also means taking special steps to protect the land, and the air we breathe. Why green? Plants are green, and 2    them the earth wouldn't be a lovely place. So here's a four-step guide：

Reduce！

When you use less of something，you do a good thing for the earth. For example，a 3    shower means you use less water, and less fuel (燃料)too. 4    your house uses fuel to run the water heater.

Reuse！

At times we want to throw things away and buy new things. Many times, if you don't need 5        any longer, someone else just might need it. For example,  if your baby grows out of 6       ，why not give them to another family who has a little kid?

Recycle！

Recycling has never been easier. Leave the things which you don't need right in front of your house and someone who needs them will7    them up. Tell your parents you'll become " Head of Recycling" for your house. That means you'll collect the recyclable things in your home and tell others  8   things can be recycled.

Enjoy！

It's true that 9    is a problem, but the earth is still a huge and beautiful place for you to live and study. You can start by 10    the naturally beautiful places in your hometown ― go for a hike,visit local nature centers and gardens, climb mountains and so on.
