    （1）　　 They stopped at a quieter area behind the library. "Strange， "I thought. "They must be up to something!" I watched them from behind a large tree and saw Jenna pass some money to Timothy.Timothy then passed the paper bag to Jenna.Both of them were smiling and seemed very happy.（2）　　Timothy must be selling answers to the holiday worksheets to Jenna!It made sense to me as Timothy was an excellent student and Jenna always needed help in her homework.I could not stop myself and jumped out from behind the tree.I cried， "(3)　　"

    Timothy and Jenna were surprised. "What is happening？" Jenna asked.After I told them what I had thought，they laughed.I turned out that in the bag was a special comic book bought by Timothy's brother.（4）　　 Once I heard the explanation，I turned red.I wished the ground would swallow（吞下） me then to save me from the shame.I said sorry for my mistake and quickly ran away.（5）
