星期天，丽丽和冬冬没事儿干，看到墙上有一大片空白，就决定在墙上画画。冬冬在墙上画了一轮金灿灿的太阳，又画了一只可爱的小鸡，最后画了丽丽手上的布娃娃。冬冬自豪地说：“你看，我画得漂亮吧？”丽丽高兴地拍着手说：“太漂亮了！太漂亮了！”
On Sunday, Lili and Dongdong had nothing to do. Seeing a large blank on the wall, they decided to draw on the wall. Dong Dong drew a golden sun on the wall, a cute chicken, and finally a doll on Lili"s hand. Dongdong said proudly, "look, I"m pretty, aren"t I?" Lily clapped her hands happily and said, "it"s so beautiful! It"s beautiful! "
这时，一位大姐姐恰巧从这儿路过，她看了看墙上的画，问道：“是你们画的吗？”冬冬点了点头。大姐姐又温和地对冬冬说：“虽然你们画的很漂亮，但是不应该在公共场所的墙上乱画。”然后冬冬惭愧地地下了头。大姐姐说：“要不我们那抹布一起把墙上的画擦掉吧。”
At this time, a big sister happened to pass by. She looked at the pictures on the wall and asked, "did you draw them?" Dongdong nods. The elder sister said gently to Dongdong, "although you are very beautiful, you should not scribble on the walls of public places." Then winter and winter went down in shame. The elder sister said, "let"s wipe off the painting on the wall together with our rags."
于是，大姐姐帮冬冬把墙上的画擦掉了。然后东东说：“我以后一定要爱护环境，我还要告诉我的小伙伴们也要爱护环境。
So, big sister helped Dong Dong to erase the picture on the wall. Then Dongdong said, "I must take good care of the environment in the future, and I also want to tell my friends to take ()good care of the environment.
