Last Monday, some Australian students came to our school for a visit. They 【小题1】(show) to visit various optional courses. One of our teachers taught them something about calligraphy. As a volunteer, I explained 【小题2】 English when necessary. They were impressed by the amazing Chinese art, and some of them even tried writing some characters successfully. 【小题3】 (remember) the enjoyable moment, we took photos together and this was really a memorable and rewarding event.
