Be a Green Child

What does it mean to be green? “Green” is more than just a color.__1__ Why green? Plants are green, and without them the Earth wouldn't be such a lovely home for us human beings.What can we do? Here's a four-step guide to being green.

Reduce It!

__2__For instance, a shorter shower means you used less water and less fuel since your house uses fuel to run the water heater that warmed up the water.

Reuse It!

Sometimes people call ours a“throwaway society”．It means that we're a little too willing to throw away old stuff (东西) and buy new stuff. __3__

For instance, if your baby brother becomes older and loses interest in his plastic basketball hoop (篮圈), why not give it to another family who has a little kid?

Recycle It!

Recycling has never been easier.Many communities will pick it up right in front of your house and some towns even require it.Recycled goods go to a recycling center, where they can be turned into new cans, bottles, and paper.

Enjoy It!

It's true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that's ready for you to explore. __4__ Go for a hike, visit local nature centers and gardens, and climb up mountains.

But before you travel the globe, take a look at your own backyard.Is there a spot where you could plant a tree or put in a little fruit or vegetable garden? __5__

A．It also means taking special steps to protect the environment.

B．Many times, even if you no longer need something, someone else just might. C．You can start locally by visiting the naturally beautiful spots in your city.

D．Turn off the water when you're brushing your teeth. E．Get out there and get your hands dirty.
