Task 1. Read the story and fill in the gaps with the words from the box.
I'm a great art lover. I look at beautiful paintings and sculptures and wish I could be artistic. I can't draw
or paint to save my life. I wonder why some people are so talented and can create amazing pictures, when other
people, like me, can't even draw good matchstick figures. I would like to fill my house with art from all over
the world. It's interesting to see how different culture have different kinds of art. There's nothing better than
visiting art galleries when you go to another country. I prefer more traditional art. I don't really understand a lot
of modern art. I look at an exhibit of a pile of bricks in a museum but can't see how it's art. I always laugh
when my children say, "Daddy, I can do better than that!" I often think they can.
Answer Yes or No
1. I love art
2. I wanted to be an artist
3. I bored while visiting art gallery

5. I like to fill my house with art from all over the world
