If it doesn't rain, the plants don't grow, If you don't study, you get bad grades, If we are not hunfry, we don't eat, If my mom doesn't work, we don't have money, If we don't have trees, we don't have oxygen, If you don't wear warm clothes in winter, you get a cold, If you don't do exercise, you get fat,
