Do I turn back? "Yes！" Will I regret (后悔) it late? I really want to get to the top, but ... At last, I decided at least to have a try.

　　My friend Tom was in front of me. Then, suddenly, he slipped (滑倒) and was about 10 feet back! My heart was beating faster until he stopped himself. Knowing that my friend Seth would be right behind me, I began the climb. I was soon past the first challenge safely, but not feeling much better about the rest of the climb. Looking down, I saw rocks everywhere. My breathing sped up, and my heart beat even faster, growing loud in my ears.

　　My friends kept climbing. But they did not forget me. Someone was always behind me to help hold my feet when necessary, and someone else was always in front to offer a hand up. With friends helping me by words and actions, I slowly gained_ground.

　　Then we came to the worst part. The climb looked very close to vertical (垂直的). To me, the wise choice was to go back down. Melody encouraged me to go on and she made it safely first. I stopped, unsure of my footing. "You can do it, Jean! I'm right here，" Melody called. She waited patiently, not asking me to hurry. I took a few deep breaths and kept climbing.

　　With no more mistakes, we came to the top finally. I was dirty and tired. But it didn't matter. I was at the top! I had never felt so alive.
