A Day in the Life of Simon Carrot
Task I: read & comprehend the following story.
At 12: 30 pm was time for lunch. I was very hungry! I sat down at the table feeling very happy because the Latin lessons were over. And then I saw what was for lunch: meat pie, boiled potatoes and cabbage. I hate vegetables! But I ate a little, because I was so hungry.
Then I went into the playground with my friends Pete Sharp and John Ford and we played football.
After lunch we had a history lesson. I don’t usually like history, but I liked this lesson very much. We learned about the Battle of Hastings in 1066. We were on holiday in Hastings last summer. I said I would bring some photographs of our holiday to school the next week.
At three o’clock it was time for my favourite lesson of the week: games. We played a very exciting game of football but it ended in a draw.
After school at four o’clock, Pete and I bought some sweets and I went to his house to listen to music.
Mum was angry because I didn’t arrive home till half past seven. She doesn`t like when I come home late. My supper was cold.
I did my French homework but I didn’t do my history homework. There was an interesting programme on television.
