Ответ:
I was ill 1 month ago.
We were doing housework when dad came home.
I called a friend, but the line was busy (линия была занята).
I was so happy to see you!
My homework wasn't difficult.
We were surprised by the teacher's recovery (выздоровление).
He was only 5 years old when I last saw him.
He was ready for anything.
They did the test before me.
Yesterday you were alone at home, so only you could break the vase.
He was very upset about the bad notes.
She was a very troubled child.
