The only hour of his day that was bearable was science class. He used to think of science as a bunch of boring words in a textbook， but Mr. O'Dell changed all that. 6 ［2］It started when Mr. O'Dell announced how students could get a good grade in his class—not by memorizing a lot of facts but by thinking. The students stared at him， either wondering what he was talking about or else marveling （惊叹） at the reddish brown hair surrounding his shiny bald head... ［3］Mr. O'Dell asked another question， “What common substance can take the form of a liquid， a solid， or a gas?” 7 ［4］Nobody answered. The class just sat there， waiting for Mr. O'Dell to explain what that had to do with anything. Then Chip got it. The first liquid he thought of was water， and then ice. Ice is a solid. And when water gets superhot， it turns to steam. He wasn't sure if steam was a gas or not， but when nobody else spoke， Chip blurted out， “Water?” ［5］After that Chip could tell that Mr. O'Dell liked him. Chip liked him too—at least most of the time. 8 ［6］The best part about science class was the field trips. Once when a student pointed out an ant， Mr. O'Dell put his nose down so close to watch that Chip expected an ant to climb right onto it and march up through the freckles （雀斑） to stare back at him through his gold-rimmed glasses. Another time， Mr. O'Dell had the whole class sit cross-legged in a circle to watch a chameleon （变色龙） change from brown to bright green. Anyone who wasn't paying close attention missed the important moment when it shot its long tongue and brought a fly back into its mouth. 9 ［7］Mr. O'Dell had the students take detailed notes on each animal or insect they were observing. He added that the creatures ought to be right where they were， doing whatever they were doing. 注意：续写词数应为150个左右。 The minute the lesson turned to science， Chip exploded with energy and enthusiasm.________________________________________ Holding a chameleon， Chip rushed into the classroom， his eyes dancing with excitement.__________________________________ 10 一审——审情节 ［1］Chip was ___________ to go to school. ［2］It started when Mr. O'Dell announced _____________________ ________________________—not by memorizing a lot of facts but by ________. ［5］After that Chip could tell that ____________________. _______________ too—at least most of the time. ［6］The best part about science class was _____________. ［7］Mr. O'Dell had the students ______________________________ ______________ they were observing. not willing how students could get a good grade in his class thinking Mr. O'Dell liked him Chip liked him the field trips take detailed notes on each animal or insect 11 二定——定主题：正能量原则 Inspired by Mr. O'Dell， Chip began to ___________ and appreciate the harmony _________________________. like school between human and nature 12 三构思——QA模式：构思每段三个微情节 根据第一段段首句可知，下文续写内容为： ［Question 1］What did Chip do in the class? ［Answer］__________________________________________________ __________________________ ［Question 2］How did Mr. O'Dell treat Chip？ ［Answer］__________________________________________________ __________ Chip became enthusiastic and energetic and actively participated in class activities.

Not only did he take detailed notes, but he also got actively involved in the class interaction. His mind raced fast and he even managed to answer a question about chameleon. （微情节一:奇普的课堂表现） Mr. O'Dell nodded with a smile of approval, obviously satisfied with his class performance. Time passing by quickly, before Chip realized it, the class was coming to 17 an end. Chip felt he had never been happier. （微情节二:奥戴尔先生对奇普的鼓励） Mr. O'Dell concluded the class by announcing the after-class assignment—everyone could choose one insect or animal to observe, record its daily activities, and eventually write an essay. In no time, Chip made up his mind and took immediate action. （微情节三:奥戴尔先生布置作业及奇普的反应） Holding a chameleon, Chip rushed into the classroom, his eyes dancing with excitement. It was the first time that he had ever touched a chameleon in person. He marveled at how sensitive it was as it changed its color with the surroundings. （微情节一: 奇普的情绪变化） The following days, Chip was no longer unwilling to come to school. Instead, he was completely changed. He became the first to come and the last to leave. He took such good care of the chameleon, made great notes and consulted anyone available. （微情节二:奇普因变色龙而收获满满） His efforts paid off. When he presented his paper, everyone was amazed at its rich contents and accurate data. Mr. O'Dell even called it as an Encyclopedia. As it turned out, without Mr. O'Dell's guidance and innovative teaching, Chip would never have taken on a new look. （微情节三: 奇普顺利完成作业；定语从句） Inspired by Mr. O'Dell, Chip began to appreciate the harmony between human and nature. （2019·全国卷Ⅰ完形填空）［Every year about 40，000 people attempt to climb Kilimanjaro， the highest mountain in Africa.］<m></m> They bring with them lots of waste. The crowds might damage the beauty of the place. ［The glaciers （冰川） are disappearing， changing the face of Kilimanjaro.］<m></m> Hearing these stories， I'm skeptical about the place—other destinations are described as “purer” natural experiences. 21 ［However， I soon discover that much has changed since the days of disturbing reports of camps among tons of rubbish.］<m></m> I find a clean mountain， with toilets at camps and along the paths. ［The environmental challenges are significant but the efforts made by the Tanzania National Park Authority seem to be paying off. ］<m></m> 22 ［The best of a Kilimanjaro experience， in my opinion， isn't reaching the top.］<m></m> Mountains are regarded as spiritual places by many cultures. This view is especially evident on Kilimanjaro as climbers go through five ecosystems （生态系统） in the space of a few kilometers. ［At the base is a rainforest. It ends abruptly at 3，000 meters， giving way to lands of low growing plants.］<m></m> Further up， the weather changes—low clouds envelop the 23 mountainsides， which are covered with thick grass. I count twelve shades of green from where I stand. Above 4，000 meters is the highland desert: gravel （砾石）， stones and rocks. ［Finally you climb into an arctic-like zone with permanent snow and the glaciers that may soon disappear. ］<m></m> Does Kilimanjaro deserve its reputation as a crowded mountain with lines of tourists ruining the atmosphere of peace? ［I found the opposite to be true.］<m></m> &1& 背铺灰语料，积续写基石 ［话题］ 人与自然——环境保护——保护乞力马扎罗山 ［内容概要］ 本文介绍了乞力马扎罗山环境遭到破坏的现状及其独特的生态系统，呼吁人们保护这一奇观。 25 ［注释］ ①山脉的基本情况 ②环境变化 ③环境变化 ④为环保所做出的努力得到回报 ⑤爬山的感受 ⑥山脚的景色 ⑦爬山的过程 ⑧表达观点 26 $
