Task 1. Read the composition and answer the questions.

A. The person who has taught me the most about life is my grandmother. My parents did a lot of
travelling when I was younger so I spent most of my school holidays with her. She was more than just a grandmother to me and when she died a few years ago I felt I’d lost a really good friend.
B. She always looked really good for her age. She had wavy grey hair and a big round face. She
was always smiling. She wasn’t very tall and she was a little plump.
C. She was such considerable person. She knew how much I missed my parents so she did
everything she could to make me feel at home. She was also really imaginative and spent hours
telling me stories that she had made up. I’m sure it was because of her that I became a writer.
D. But as well as keeping a young boy entertained, she taught me so many important things. I
was very impatient when I was a child and she taught me that good things happened if you could
wait for them. She was such a positive person and she also taught me how to look for the good in
everything.
