My name is Peter. I come from London. I have two good friends. They are Linda and Bob.
Last Sunday, it was sunny and hot. We went to the mountains by bike. We played with water, took some photos and ran after some butterflies. How happy we were! Suddenly, Linda shouted loudly. Oh, she saw a snake. "Don't shout. It's very normal to see snakes in mountains." Bob said to her.
In the afternoon, we began to climb the mountain. When we were on the half way, it began to rain. Linda and I were very scared. And we began to cry. Bob asked us to be calm (冷静的).
With his help, we climbed down the mountain safely. Later, we went back home after the rain stopped. I think Bob is very brave (勇敢的). Do you think so?
