My sister was going to have a birthday party. She was very fond of clowns, so I had an idea to invite a clown for entertainment. Unfortunately, the man who usually acts as a clown was sick. I didn't know what to do since I didn't want to disappoint my sister. I had told her that I would present a clown on her party. After thinking for a while, I decided to be the clown. I watched You Tube about a clown's performance and irita ed it. Actually it was difficult to act like a clown, but I enjoyed it. Then, the day arrived. Several hours before the party. I wore a clown costume and made up my face, helped by my cousin. I looked at the mirro.. What a very funny face! A face with a thick make up! I welcomed the guests and entertained them. They smiled and laughed at me. Several of them took photograph with me. It was time for cutting the birthday cake. To my surprisc, my sister approached me and gave me a piece of her cake. She stared at me with glistening eyes. 17. What is the text about? A. A predictable event. B. A surprising moment. C. A memorable experience. D. An tiring occurrence. 18.
