    My dentist had just pulled out one of my tooth and had told me to rest for while. My mouth was full with cotton wool. He knew I collected bird eggs and asks me whether my collection was growing. He then asked me a lot of other question. In answer to these questions, I could neither nod nor make strange noises. Meanwhile, my tongue was busy search out the hole where the tooth had been. I suddenly felt very worried, so couldn't say everything. When the dentist at last removed the cotton wool, I was able to tell him of that he had pulled out the wrong tooth.

    I always wanted to be great scientist. I had these dreams of discovering a new drug that would save the life of hundreds of people. Unfortunate, I was never very good at chemistry at school and the teacher used to getting very angry with me. After a while, I decided I would become an inventor and designed an only product which would become a household name. My parents were quite encouraged, but told me to be a little more realistic. A few weeks late, I had a clever idea for a pen that would write with upside down. To my disappointment, a friend of me pointed out it was not a new discovery.

    If we often question whether that we are told is true, we can find the correct answer and learn more. Several days ago, our teacher offered us an answer to a difficulty math problem in class. Although an answer seemed a little strange, but only I doubted it. I thought of his answer might be wrong, I carefully considered the problem and tried to work them out in a different way. Half an hour late, I finally managed to find the correct answer. When I showed the answer to him, the teacher praised me for my independence thinking.

    From this experience I had already come to the conclusion that questioning can serve as a bridge where helps us find the truth.

    Now I'd like to tell you something that took place in my school yesterday. In the afternoon we had held a grown­up ceremony for our come 18­year­old birthday. At first we made an promise that as grown­up we should have a sense of duty for our society from now on. Then we expressed our thanks to our parents they had gone through hardships to bring us up and our teachers who had been educating us patient. And our teachers also gave them cards expressing their good wishes. Finally we put on wonderfully performances, singing or dancing. We learned a lot from the activity. I think it is of great important for us. I will never forget that day in my life.
