     "2 didn't French seem so interesting before?" I asked myself.

    But I knew the answer. It was my last French lesson, and I regretted not studying hard before. I 3 to listen very carefully. Mr. Hamel was trying to teach us everything he knew. He had never taught a lesson so well before.

    The grammar lesson finished, and then we started 4. I had never seen so many hardworking students before. Everyone had their 5 down, and the sound of pens on paper was the only sound to be heard.

     I looked at Mr. Hamel. He was sitting still in his chair. The only things he 7 were his eyes. He looked carefully at one thing in the classroom for a while 8 looking at the next thing. For forty years, the only classroom was like his 9, and now it was being taken from him.
