I had never been to such an amazing national park before, yet I wasnt the most athletic person, so I knew that I couldnt stick through all the hiking up and down. It actually ended up being a fun and adventurous experience.The ride there was definitely long but worth it. As I woke up from my nap, I saw the beautiful scenery of the tall mountains and beautiful streams. The trails were made nicely for visitors. The waterfalls were breathtaking. Climbing up rocks was one of my favorite parts. Even though I fell a couple of times, I still had a lot of fun. The fact that my family and I spent so much time together trying to find out which route to take and what views to watch really brought us closer together.The great thing about nature is that, its just you, the views, and the people around you. Theres nothing there to bother you and its the best way to relax and enjoy yourself. Yosemite has 5 of the worlds highest waterfalls, and about 300 lakes. The structure of each mountain is incredible; its formed in ways that almost take your breath away. Some of them are of a deep dark color with waterfalls forming; some are formed with spots of green peeking (窥探) out. Its definitely something you wouldnt want to miss.Yosemite isnt the only great National Park but based on my experience I highly remend going out and enjoying nature with family and friends. Its a great time to bond, laugh, and take in what Mother Nature offers.语篇解读：文章记叙了作者一家去约塞米蒂国家公园游览的所见所闻，与家人一起出游其乐无穷。作者建议读者多外出走走，享受大自然之美。5The author writes the first paragraph mainly to _.Aintroduce the topic of this passage Boffer an example to usCtell us his future plan for hikingDdescribe a national park解析：选A推理判断题。文章第一段第一句首先提到Yosemite，该段最后一句“It actually ended up being a fun and adventurous experience.”起到承上启下的作用，下文展开介绍作者此次去约塞米蒂国家公园游览的所见所闻。由此可推测，作者写第一段是为了引出文章话题。故选A项。6While climbing up rocks, the author was _.Anerveracking BinjuredCpleased Dworried解析：选C细节理解题。根据文章第二段第五、六句“Climbing up rocks was one of my favorite parts.
