During the past year at high school, I had many experiences 【小题1】 were unforgettable. One of them was when our class 【小题2】 (prepare) for a group singing competition. In order to win the competition, we went all out for it. During the week before the competition, we practiced 【小题3】  (sing) in our free time. Although it was 【小题4】 hard job, every participant took it 【小题5】 (serious) and did their best. Thanks to our effort, we won the 【小题6】  (one) prize. Hearing the 【小题7】  (excite) news, we were all wild 【小题8】 joy. The moment we got the prize, an old saying hit 【小题9】  (me) mind----No pains, no gains. It was hard work, but during the course of preparation, we developed friendship,【小题10】 (confident) as well as understanding.
