it's easy to do the homewoek. it's difficult to do the job. it's important to finish the work. it's helpful to take a walk. it's useful to read the newspaper. it's happy to hold a party. i didn't sleep until mum came home. i didn't go home until it was dark. i didn't cry until i felt it hurt. we didn't go for a picnic until it cleared. you didn't leave until you finished the work. you didn't go away until the teacher came.
