When I walked into the classroom, the teacher was handing         in the tests. I was feeling very nervous. I had not studied       at all at the weekend as I had thought it would be easy test.     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  on my shoulder! The teacher caught me cheating. I don"t           know what to say. Luckily, the teacher did not punish for         cheating but instead gave me the second chance.	1______ 2______ 3______ 4______                                        5______ 6______ 7______ 8______ 9______ 10______
