     The summer I was ten, my mother decided to bring us to the world of art. My brother and I were

not very excited when we realized what my mother meant. What she meant was not that we could take

drawing classes or painting classes but that we would have to spend one afternoon a week with her at

the Fine Arts Museum. Before each visit to the museum, she made us read about artists and painting

styles(风格). It was almost as bad as being in school. Who wants to spend the summer thinking about

artists when you could be with your friends at the swimming pool?

     First we had to read about ancient Egyptians(古埃及人)and their strange way of painting faces and

then go to look at them at the museum. My 12-year-old brother  thought this was so funny, but I was not

interested. Later we had to learn about artists in the Middle Ages who painted people wearing strange

long clothing. We had to look at pictures of fat babies with wings and curly(髫曲)hair and with no clothes on flying around the edges of paintings. I certainly couldn't see what was so great about art.

     On our last visit to the museum, something happened when I saw a painting by a woman called Mary.

In it, a woman was reading to a child. The colors were soft and gentle, and you could tell by the mother's

expression how happy she was just to be with the child. I couldn't stop looking at this painting! I wanted

to see every painting Mary had ever made! It was really worth looking at so many paintings to find a

painter who could interest me so much.
