My mom said，“I like the idea of you exercising that clever brain of yours.But I also want you to get plenty of fresh air.” “Campers can choose to hike or swim every afternoon！” I said，as I clicked on the registration form. My dad filled out the form，and weeks later，my parents dropped me off for what I thought would be a week of nonstop computer-coding fun. I arrived at the check-in table at the same time as a camper of my age named Halley，who was wearing an adorable sunhat.Halley greeted，“We are in the same group—number 7.” Led by an advisor，we followed the green arrows to the campsite. I surprisedly found that it was so cool and woodsy along the path.I exchanged ideas with Halley about what might come out of the camp.Halley excitedly mentioned the little animals he loved to observe and something about night sky watching. “You gave me the best idea，” I said.“I’ll base my characters on the animals you mentioned！” Halley laughed.“I might be missing something here.Who are these mysterious characters？” “You know，the characters we’ll be designing and animating on computers this week！” I said.“Uh，sorry.Still lost，” said Halley.“Why would we be doing computer stuff at Nature Camp？” It was then that I realised some errors must have been made.I must have accidentally clicked on the wrong online form! We immediately raced back to the welcome table to see if I could switch over to Tech Camp，but of course it was completely full. 注意：1．续写词数应为150左右； 2．请按如下格式作答。 I forced a smile as we headed for our campsite. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 学生用书第149页 “OK，I’ll have a try，” I looked at Halley thankfully._______________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ [读后续写四步曲] 第一步　通读全文，理清脉络 1．读要素，弄懂故事大意 本文大意：作者参加夏令营，选择了编程项目，但是发现自己选错了夏令营。他想要改成技术营，却发现已经满员了。 2．读人物，理清人物关系 My parents，Halley and I 3．读时态，确定主体时态 一般过去时为主。 4．读结构，了解叙述方式 第1段：作者报名参加夏令营，选择了编程项目。 第2－3段：报名之后，父母送我参加夏令营。 第4段：报到时遇到了同龄人Halley。 第5－8段：与Halley的交谈中作者发现自己选错了夏令营。 5．读语言，把握语言特色 原文中的语言特色： (1)语言描写 ①“Campers can choose to hike or swim every afternoon！” I said，as I clicked on the registration form. ②Halley greeted，“We are in the same group—number 7.” ③“You gave me the best idea，” I said.“I’ll base my characters on the animals you mentioned！” Halley laughed.“I might be missing something here.Who are these mysterious characters？” (2)情绪描写 ①I surprisedly found that it was so cool and woodsy along the path. ②Halley excitedly mentioned the little animals he loved to observe and something about night sky watching. 第二步　依据首句，构思框架 1．读懂两段首句 第一段首句译文：我们朝营地走去，我强颜欢笑。 第二段首句译文：“好吧，我试试。”我感激地看着Halley。 第一段框架：我对没有选择技术营感到遗憾，Halley安慰我，并鼓励我体验大自然。 第二段框架：如何探索大自然以及自然夏令营带给我的享受。 2．写好两个衔接句 第一段首句后的衔接句：As I stepped forward，I just felt so disappointed that I had to sit down. 第二段首句后的衔接句：We reached the campsite and started to explore the nature. 3．写好一个结尾句 Try not to stay stuck in the negative for a whole bunch of amazingness really is just waiting to jump out and surprise you！ 第三步　增加细节，展开续写 基于第一段的框架，我们可以补充以下细节：走向营地(感到遗憾)→(后悔没有选择科技营)Halley安慰我→给我鼓励(提议我感受自然)。 基于第二段的框架，我们可以补充以下细节：尝试自然营(发现自然营很神奇)→享受快乐→我的感受(不要深陷负面情绪之中，或许很多惊喜在等着你)。 第四步　检查优化，整洁誊写 ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ I forced a smile as we headed for our campsite.As I stepped forward，I just felt so disappointed that I had to sit down.Seeing that，Halley sat next to me.For the next few minutes，regret immersed me as my treasured Tech Camp slipped away due to my inattention.Then Halley broke the silence，whispering kindly，“I guess it was the call of the wild.” I responded with a bitter smile.I was presented the stuff I could enjoy from nature，suggesting we hike and experience it.“You can discover unexpected excitement.” he encouraged me. “OK，I’ll have a try，” I looked at Halley thankfully.We reached the campsite and started to explore the nature.Nature Camp turned out amazing!
