I really enjoyed the scenery during the trips, which made me feel relaxed. What’s more, the nature could always bring me a good mood.B: I had some experiences of travel. However, the most impressive trip I’ve made was the one I went to Zhoushan Islands. Owing to some unhappy things that happened to me several months ago, I needed to take a walk to have some fresh air and to forget the past. I know there is nothing like nature that can make me feel fortable, I like beautiful things such as blue sky, boundless sea, wonderful breeze, soft beach and so on…C: So have you relaxed yourself successfully there?B: The trip was so wonderful that I would never forget. I spent most of time visiting the tourist attractions.

For me, I will never forget the days I spent in Dalian.A:I desire to go to Dalian. Please share it with us.D: I paid a visit to Dalian last summer vacation with my family. It is a quite beautiful city. We played at the seaside. The sea there is deep blue and the sky is so clean. On the beach we stepped on the blocks of stones and pebbles, looked at large numbers of waves rushing up to us one after another. The breaking waves hit on the rocks and left the beach covered with foam. We felt cool and were wet all over. And the next day we took a bus to a golf court, which was the first time that I had seen how golf was played. There I have learnt how to hold the bat and hit the ball.A：That is really a trip worth remembering. What about you, C, do you have some interesting experiences?C: Yes. There are many trips in my memory. Among them, I never forgot that day when my family made a trip to visit Mount Huang in May. On the half way through the mountain I saw a sea of green trees. The trees were standing straight pointing upright to the sky. White clouds floated in the blue air. The bus zigzagged to the station. As we all know, the Mount Huang is the most difficult mountain to climb. And only the brave few took the path. Following the guide I began climbing on all fours. It was a test of physique as well as courage. The narrow steps in the mountain led us higher and higher to the summit. At last we got to the summit. Standing above and looking down everything was in sight beneath me. It was magnificent and enlightening. ABD: Oh, it is amazing that you got the summit successfully by yourself. Yeah, you are so brave.
