If the weather is fine, I'll go to the park
If I have enough money, I'll buy a new car
If she study hard, she'll pass the exams
If you have free time, we'll watch the film
If they get up early, they won't be late
water boils if the temperature is 100 degrees
she wears the glasses if she reads
the car is clean if you washes it
she will have time for reading if she comes home early
people wear hot clothes if it's cold
