One possible version:
My parents and I made a tour to Xian during the holiday. Instead of having a travel agency arrange our accommodation, we booked the train tickets and hotel room on the Internet by ourselves. During our tour in Xian, we went to many places of interest, took lots of pictures, and learned about the history of Xian. No tourist will miss the local food in Xian, nor will we. We enjoyed typical local foods, which tasted nice. After I returned, I couldn’t wait to share the photos and experiences with my classmates. The trip to Xian has become a happy memory to me.:
试题分析：这是一篇看图写作，一共四幅图。做题时：1. 认真读图，可知四幅图讲述的是你和父母去西安自助旅游的 经过，2. 初步构思，考虑用词、短语、句型和时态。3. 连词成句，然后再连句成文。尽可能地充分利用所学的短语或句型来表述具体的内容。4. 反复审核，修改错误。5. 注意所给的汉语提示。一般说来，看图写话中的汉语提示往往给定了有关的时间、地点、人物等相关的信息，还有参考词汇都是有用信息。在把握了文章的中心后，应在内心构思一个基本的框架，并考虑使用恰当的词语、短语和句型，以充分地表达文章的内容。这是体现自身能力的重要一环。然后再将各图的单个句子串连起来。串连时，要注意使用适当的连接词语或过渡性语句，不至于让读者觉得文章中出现跳跃现象，更使上下文更为紧凑、自然。
【亮点说明】所给范文条理清晰，语言简洁，应用了一些较好短语的句子：made a tour to 到…旅行，Instead of 代替，by ourselves自己，places of interest名胜, took lots of pictures拍了很多照片，ouldn’t wait to 迫不及待的做…No tourist will miss the local food in Xian, nor will we. 这句话用了倒装句，We enjoyed typical local foods, which tasted nice. 这句话用了非限制性定语从句。
