Today we were organized for a short trip to the West Hill. We set out by the school bus at 7:30 a.m. The weather was pleasure and every one of us was excited. After   two hour’s ride, we arrived there at nine thirty. We began our programs the moment as we got off from the bus. We played games on the hillside and swimming in the river. After that we had our picnic lunch. In the afternoon we walked along the river, that winds around the hills.  We took a lot of photo and enjoyed ourselves very much. Time past quickly and we had to come back. It was over five o’clock that we returned school. What a good trip we had today! I’ll never forget it.
