In the summer holiday, the weather was hot and my parents persuade me to take swimming lessons. I still remember the first day clearly. Before jumped into the water, I thought I had learnt the. teacher's instructions, and once I was in the water, my mind went blank. I forgot that he had taught me. The teacher repeated the word, “Hold your breath!” “Move legs quickly!” “Pushing the water!” I was so much nervous that I moved my hands and legs aimlessly. Exhausted, I felt my body sinking slowly. Luckily, the teacher took me back on time. A few minutes later, he gave me a carefully explanation once again. What unforgettable day!
