Question 2: Last Sunday Jenny went to the circus with Eddy and Willy to spend their school holiday. First, they saw the seals performance. The seals balanced themselves on tires and rolled round the ring. A seal balanced on a stool with an umbrella on its nose. After that, the trainer fed them fish. The next item was knife-throwing act.

Everyone held their breath when the lion trainer put his head into the lion’s mouth. Finally, it was the clown’s act. Jenny and her brother liked the clown’s act best. They looked funny with their painted faces and baggy costumes. One of them swung a pail at Jenny. She screamed! Scraps of paper flew out of the pail and audience laughed.
