One day after school, I went to the teacher's office to see my teacher, but nobody was there. As I was about to leave, I noticed a piece of paper on the floor. I picked it up and saw the words "FINAL-TERM EXAMINATION" at the top. I put the paper into my school bag secretly and ran out of the room. After I came back home, I took out the paper quickly. It was the exam paper of my worst subject, History. I felt excited. My heart beat fast. I took out my History book and started working on the answer. I had never answered any questions so seriously. On the day of the History exam, I went into the exam hall confidently. When the paper was sent to me, I dreamt of getting the highest mark in the whole grade and could not help smiling. "My History teacher always encouraged me to work hard and get better grades, but I let him down time and time again. This time I will give him a big urprise," I thought. When the teacher said we could start, I turned the paper over. To my

C
Making a good job choice is almost as good as choosing a good life. So, choosing a job is one of the most important decisions to make in life. For my job, there are three important things that I will consider:
The first one － that I must work in an area I like － is most important to me. Someone once said if you find a job that you enjoy, then you won't have to work another day. I would like to work in an area where I can be more creative. I would like to be the most valuable member there. All this is possible only if I like what I do. The second one is that the area of my work must lead me to solve some new and hard problems. I would like to stay in the same area for a long time. In order for this to happen, the work must provide enough problems. More than just working to live, I enjoy making a difference and trying my best for the whole progress. I would also like to be well remunerated for my hard work, so I can lead a comfortable life with this hard-won money. Then I can provide the best for my family. The third important thing is that I would like to work in an area that would help other people. The work in my mind is in fields such as the army, training or management. In such areas, I can help to develop the abilities of others and bring out their best. It would be a most satisfying job to help young people to become the best that they can be. When I become old, I would like to look back with a great sense of satisfaction that thousands of people have become better persons through my work.
I accept the idea that no one should make a choice of a job suddenly or quickly. He should decide what he wants to be in the long run. Then, he should decide how he works towards it. He should study the proper courses, read the books and speak to knowledgeable persons in that field before making a job choice. A good choice will most probably lead to a better life.
