to caviar：China's hidden agricultural treasures revealed in unexpected exchanges This winter，tourists from southern regions flocked to Northeast China for vacations and were greeted with warm hospitality and attentive care from locals.In a gesture of gratitude，various regions sent their local specialties to the Northeast，and in return，the Northeast reciprocated with its own local products. However，the nature of these specialties turned out to be completely unexpected，even to many locals.For instance，Heilongjiang province sent cranberries to the Guangxi Zhuang autonomous region，and Sichuan province reciprocated with caviar to Harbin.These unexpected exchanges left not only outsiders unaware of the agricultural products in these regions but also astonished locals，who exclaimed，“So，‘local specialty’ actually means ‘intentionally produced behind locals' backs.’” This wave of surprises has prompted people everywhere to start exploring the hidden agricultural products of their own hometowns.From Xinjiang's salmon to Anhui's foie gras and Shanghai's saffron，it turns out that each region has its own hidden treasures. When it comes to foie gras，many people immediately think of France.However，in Huoqiu county，Lu'an，Anhui province，one can find authentic French-style foie gras.Lu'an has a history of raising geese and is known for the high-quality local white geese. 词海拾贝 1．flock v． 蜂拥，聚集 2．gratitude n． 感谢 3．exclaimed v．惊叫，呼喊 4．treasure n． 宝藏，珍宝 阅读理解 阅读文本，回答问题 1．Why did tourists flowed into Northeast China this winter? __________________________________________________________ 2．What's the discovery of the unexpected communication? __________________________________________________________ 返回 They went there for vacation.

On the fifth day，the river began to rise.It wasn't long before water came streaming into Frog's house.Full of worry，he hurried over to Duck's house only to find it was flooded as well.Wading (蹚) through the watery landscape，they decided to go to Pig's house.Pig was leaning out of his attic (阁楼) window.“All my things are wet，” he cried desperately.The room was in a mess，with tables and chairs floating around.“Let's go and see Hare，” suggested Frog. Hare's house was on an island in the middle of the water.Hare stood at the door and waved to them.“Come inside，” he shouted.“It's dry in here.” Gratefully，they dried themselves in front of the stove and told Hare how their houses had been flooded.Hare invited them to stay as there's plenty of room and plenty of food in the house.So they all sat down to a big pot of stew (炖菜) Hare had made.So hungry were they that they ate everything up.Then they settled down to a cosy evening and stayed there for days，while outside it kept raining. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 Then，one day，they found they only had one loaf of bread left._______ ________________________________________________________________________________________________________________________________ ________________________________________________________________ Pig，Duck and Hare cheered when they saw Frog return in a boat.______ ________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________ 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：因为几天的大雨青蛙和他的动物朋友们的家被淹，于是他们聚在野兔家避难。 2．读人物，理清人物关系 Frog and his animal friends. 3．读时态，确定主体时态 一般过去时为主。 写作思路 4．读结构，了解叙述方式 第1段：天空下起了大雨。 第2段：连续下了几天的大雨，青蛙担心他的朋友们。 第3段：大雨淹没了青蛙以及鸭子和小猪家，他们决定去野兔家。 第4段：大雨继续，小动物们决定待在野兔家。 5．读语言，把握语言特色 原文中的语言特色： (1)环境描写 ①...dark clouds were gathering in the sky，hiding the sun from view. ②The raindrops pattered against the window but it was cozy inside. (2)动作描写 ①He danced for joy as the raindrops fell thick and fast. ②He ran home dripping wet and made himself a nice hot cup of tea. ③Wading (蹚) through the watery landscape，they decided to go to Pig's house. ④Hare stood at the door and waved to them. ⑤Gratefully，they dried themselves in front of the stove and told Hare how their houses had been flooded. (3)情感描写 ①Frog began to feel restless. ②Full of worry，he hurried over to Duck's house only to find it was flooded as well. (4)语言描写 ①“All my things are wet，” he cried desperately. ②“Let's go and see Hare，” suggested Frog. ③“Come inside，” he shouted.“It's dry in here.” 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：__________________________________________ 第二段首句译文：____________________________________________ 第一段框架：青蛙主动出去找食物，他在途中遇到的危险，以及如何找到小船回到大家身边。 第二段框架：朋友们对青蛙的赞美和感激，以及雨过天晴，一切恢复 正常。 然后，有一天，他们发现只剩下一条面包了。 小猪、鸭和野兔看到青蛙坐船回来时欢呼雀跃。 2．写好两个衔接句 第一段首句后的衔接句：Deeply worried，they were sitting in dead silence when Frog stood up and offered to find food. 第二段首句后的衔接句：Seeing his friends，Frog waved with great excitement，“I've brought us a lot of food.” 3．写好一个结尾句 The next thing they knew was morning，when the rain stopped and the sun came out，casting a red glow over the village. 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： 食物所剩无几(他们非常担心，坐着默不作声)→青蛙主动出去找食物(毫不犹豫地出门)→途中遇到困难(路上遇到旋涡)→化险为夷，找到食物。 基于第二段的框架，我们可以补充以下细节： (青蛙兴奋地向朋友们招手)朋友们庆祝青蛙回家(朋友们抓住青蛙的胳膊，并拥抱他)→赞美与感激→朋友们饱餐一顿(饱餐之后，动物们安心入睡)→雨过天晴，恢复正常。 第四步　检查优化，整洁誊写 Then，one day，they found they only had one loaf of bread left.Deeply worried，they were sitting in dead silence when Frog stood up and offered to find food.He headed for the door，stepped out and jumped into the bitterly cold water，without hesitation.Unfortunately，in the midway，he ran into a whirlpool and kept going round in circles at great speed.Noticing that heavier objects went down more quickly，he swiftly grasped a barrel nearby，tied himself to it and tried to flee.Finally，he made it to the Rat's，where he found abundant food as well as a boat，and hurried back to the Hare's. Pig，Duck and Hare cheered when they saw Frog return in a boat. Seeing his friends，Frog waved with great excitement，“I've brought us a lot of food.” As soon as the boat landed，the three grabbed Frog's arms，gave him a hug and cheered，“You are a real hero！”Hearing this，Frog was glowing with pride. That night，they held a party，swallowed a big meal and fell into a sound sleep. The next thing they knew was morning，when the rain stopped and the sun came out，casting a red glow over the village. 九寨沟国家级自然保护区位于四川省阿坝藏族羌族自治州九寨沟县，主要保护对象是大熊猫、金丝猴等珍稀动物及其自然生态环境。九寨沟县以有9个藏族村寨而得名。 Geography地理 Jiuzhaigou Valley is a nature reserve and national park located in Jiuzhaigou County in the Aba Tibetan Qiang Autonomous (自治的)，Sichuan province.Jiuzhaigou takes its name from the nine Tibetan villages along its length. 九寨沟自然保护区位于四川省阿坝藏族羌族自治州九寨沟县。九寨沟县，以有九个藏族村寨而得名。 用英语讲中国故事 Ecology 生态 Jiuzhaigou's ecosystem is classified as temperate broad-leaf forest and woodlands，with mixed mountain and highland systems.The forests take on attractive yellow，orange and red hues in the autumn，making that season a popular one for visitors.Local fauna (动物群) includes the endangered panda and golden monkey. 九寨沟生态系统属温带阔叶林，也有山地和高原生态特点。森林树木在秋季时，呈金黄色、橙色、红色。金秋季节成为九寨沟的旅游旺季。当地的动物有珍贵濒危的大熊猫和金丝猴。 Scenery Features景观 It is a great masterpiece(杰作) of nature having dreamlike scenery，which combines blue lakes，waterfalls，verdant forests，snow-covered mountains，and the folk customs of the Tibetan and Qiang peoples. 九寨沟自然保护区的梦幻美景是天然神作，蓝色湖泊、瀑布、葱郁的森林、冰雪覆盖的山峰，还有藏族、羌族的民俗风情。 返回 谢 谢 观 看 ！ 返回 $
