I went through the test for many times but I could only answer three out from the twenty questions. I did not want to fail the exam. Then , I put my book under my desk, opening it and started looking for the answer. The teacher wasn’t looking at me ,but I copied something. Suddenly, I felt a hand in my shoulder!
