Today I went on a school trip. We (visit) the science museum and it was really interesting. We got there so fast by train. We saw some farms and villages the way. At the museum, I (learn) a lot about robots. I didn't know they could play chess with us. It was so cool! Then the guide taught us how (make) a model robot. I took a lot of great photos, too. After that, l went to the gift shop and bought some lovely gifts for my parents. They (not be) expensive. All in all, it was an exciting day.

I think today's school trip was terrible. We (take) the train to the museum. It was so hot on the slow train. The museum was big and boring. Everything (be) about robots and I'm not interested in that. The rooms were really dark and it was difficult (take) photos, I didn't take any. There were also too many people and I couldn't really see or hear the guide. The things in the gift shop were so expensive. I didn't like the trip all.
