Last Saturday I went to the library as usually. At about noon, I was enjoying my reading near a lake while suddenly I hear someone crying for help. I went up to see what was happened. I was shocking to find a little child struggling in the water in the distance while many peoples were standing by without doing anything. Without any hesitation, I had pushed through the crowd as I took off my coat, but jumped into the water quickly. I managed to reach him and carried him back to safety. To his great relief, the kid was saved.

I am proud what I did. I hope everyone can give a hand when someone else is in need.

The other day, I take part in the National English Debating Competition. I have a lot to share with you. At first, I feel really delighted what I’ve won the first prize in the competition, which makes me understood the true meaning of the proverb ＂no pains, no gains.＂ Furthermore, in the five-days competition, I established a closely friendship with students from all over the country, from who I’ve learned a great deal. More importantly, taking this competition have enabled me overcome my fear of speaking in the public, thus developing my self-confidence. Additionally, I owe many thanks for my teacher and the judges, without whose help, I couldn’t have done such an excellent job.
