如何保护我们的世界更美丽 HOW TO MAKE OUR WORLD MORE BEAUTIFUL Taking care of our environment is our duty.But how we can do to make our environment more beautiful? At first,we must make ourselves clean.For example,we must wash our clothes when they are dirty.We should not litter waste things about,and draw on the wall.We mustn't spit in public or cut down trees. We should plant more trees around our neighbourhood.We should pick the rubbish up and throw them into the dustbin when we see them. We must make our world more and more beautiful,don't you think so? |
