1 I go to the seaside once a year
My teacher often speaks about the USA
He writes a dictation twice a month
I put my books on the shelf every day
2 I studied at a medical school two years ago
He spoke English at the last lesson
My mother liked my cake yesterday
She put her bag on the table an hour ago
