were too many words that he didn't know. He saw that Pavel was already doing
the task on the text. It____________________ that he knew the words and the teacher had explained
them at the lessons. Andrey tried ____________________________ to remember when

He thought the same when he came to_________________________________on
the next

day and jumped up with surprise when Pavel___________________________________for
