Write a composition, what is the paragraph, about 300 words.

Not long ago, at my strong request, my mother spent 2000 yuan to enroll me in a two-month self-swimming training class at Xinfeng Swimming Pool. Originally, I thought my dream would set sail from here. However, unexpectedly, the hardships began here.

I remember the first day of the training class, the coach said to us with a straight face and a loud voice, "I am the coach of your training class, and I will only give you two months." After two months, every student must pass the freestyle exam. Did you hear that? "Oh, my God, it's been two months! This is a fantasy for me who has never been in the water. " Listen, listen ... I hear you. "My heart can't help but tremble. I realized that I met a hurdle in my life, but now that I have chosen, I have to cross it!

The coach taught us to practice stuffy water that day. I saw the coach take a deep breath, dive into the water and come up after a long time. Next, he asked us to practice by ourselves. When I was a child, I was choked by water when I was washing my hair, so I didn't dare to go down when I looked at the water in this pool. Finally, the coach forced me into the water. Pull my head and push me into the water. I rocked like a fierce horse trying to break free from the rope. But as a child, how can I come down after a few rounds? Not only did it not work, but I choked several times. I feel terrible and have a bad cough. But the coach seems inhuman and looks at me like a supervisor. "dive into the water, don't inhale, exhale!" Exhale "His broken gong voice rang again and again. 10 seconds, 30 seconds, 50 seconds, 70 seconds ... 15 days later, I finally mastered the skills of blocking water.

The next day, the coach asked us to practice freestyle swimming on the shore and thought we did well. Somehow, when we dive, our hands and feet don't work. I had to "climb" ashore again, honestly, repeating that rough and boring action over and over again. A month later, I finally mastered it.

The last level is also the most difficult-getting some air. It must "combine" the previous links. It's been a month and a half since I was alone with "One" and "Two". It's hard to talk about "three in one" anymore! But on second thought, I can't be discouraged. You have passed two levels. How can this third level be defeated? "I secretly bullet, according to the coach told us formula, practice in the water again and again.

Many things happen. Half a month later, when I heard the whistle of coach Benedict and jumped into the water, I knew I had crossed this hurdle!

In fact, the road of life has never been smooth sailing, and everyone will encounter all kinds of obstacles. If you go forward bravely like Liu Xiang, you will be able to cross one hurdle after another, and your life will be full of brilliance and joy.
