If it doesn't rain today,
If Sam doesn't water the plants,
If they have a toothache,
If eat too much candy,
If I feel sick,
If you study hard,
If you eat healthy,
If we don't sleep well,
you get a stomachache.
we feel very tired on the next day.
you get good grades at school.
they go to the dentist.
they die.
we can play in the park.
you stay in good shape.
I don't go to school.
