My mom is pretty cool. She is always trying to come up with ways to give the environment a helping hand. One day, she brought a green 1 to work. At lunch, she shared the cake 2 friends. Everyone liked it. They were all surprised how she made it.
The story goes back a few weeks. Our city 3 a new recycling program—families were supposed to separate food rubbish from the other kitchen waste.
My 4 loves fruit. My father especially loves watermelons. He 5 a lot of them in the summer. The skin (果皮) always ends up in the rubbish. That's almost half the weight of a watermelon!
After a lot of thinking, my mom found a 6 way to use all the melon skins. She brought out the blender (搅拌器) and cut the melon skins into small pieces. 7 she blended them, she got a whole cup of green watermelon juice. Then, she mixed the juice with flour (面粉). From there, she 8 made her delicious GREEN cake.
What a great product of the melon eating! And it was nature friendly too. From now on, my mom doesn't need to 9 the heavy waste from eating melons. And everyone always wants more of her 10 cake.
