增肥 Put On Weight

Though there are many people want to lose weight, I want to put on weight. I am ten years old and my weight is about 20kg. The children around me all treat me as the small sister. I am already ten years old, but they treat me as a child. And sometimes I want to help my mother to clean the dishes, but she always rejects me because I too small to catch the desk. If I can put on some weight, everything will be different.
虽然很多人想减肥，但我却想增肥。我十岁，而我体重只有20公斤左右。我周围的小孩都把我当成小妹妹。我已经十岁了，但他们还是像小孩一样对我。有时我想帮妈妈洗碗，但她总是拒绝我，因为我太小了够不着桌子。如果我能够增肥点，应该就会不一样了吧。
