Unit30.The Power of Nature连词成篇A Volcano EruptionAs the best candidate,I was appoint ed to collect and evaluate information for a database about diverse natural disaster s,such as hurricane s,typhoon s or thunderstorm s.Sometimes I did this by giving out questionnaire s to those who went through them.But sometimes I had to go through actual disasters myself.The Musaki Volcano was one of them.At that time,I lived in a bungalow alongside the volcano with a novelist,who came for the appreciation of its eruption.One day,when I was draw ing diagram s on the balcony and he was bath ing inside,the volcano erupt ed unexpectedly.The ash and lava fountain s shoot ing highly in the sky varied from50to100meters in height.It was absolutely fantastic!I even noticed a rainbow appear in the fog cause d by a heat wave.But,glanc ing through our surrounding s,I foresaw the potential danger and found no guarantee of our safety. The uncomfortable gas almost made us unconscious.Sweat s of anxiety began to drop.Managing to stop panic king and trembl ing,we quickly put on our protective suit s,helme ts and boots and eventually made our way to a safe place.How lucky we were even though my precious equipment and document s were all burnt to the ground!词汇详解1.volcano[]n.____________2.eruption[]n.________________________vi喷发，爆发3.candidate[]n.______________3.appoint[]vt.______________appointment n._____________________appoint sb.as______________appoint sb.to do sth._____________make an appointment with______________4.collect[]vt.________________collection n.___________________5.evaluate[]vt._______________rmation[]n._______________7.database[]n.___________8.diverse[]adj.___________diversity n._______________9.disaster[]n.____________10.hurricane[]n.____________11.typhoon[]n._____________12.thunderstorm[]n.__________13.sometimes[]adv.___________sometime adv.__________some times_______________________some time_______________________14.give out_______________give off_____________give in___________give up____________give away________________give way_____________give birth to_________________15.questionnaire[]n._______________16.actual[]adj._________actually adv.___________in actual fact______________17.bungalow[]n.___________18.novelist[]n.___________novel n._____________adj._______________19.appreciation[]n._____________appreciate vt._______________appreciate(one’s)doing sth.____________________I’d appreciate it if you could do sth.______________________20.diagram[]n._______________21.balcony[]n.______________22.bathe[]vi._________________________n.沐浴have a bath___________________23.unexpectedly[]adv.___________expect vt._________________________n.期待，预料24.ash[]n.__________va[]n.____________26.fountain[]n.____________27.shoot[]vt._________________(shot,shot)_________n.射击28.vary[]vi._______________________adj.各种各样的______________n.多样化，多样性a variety of/varieties of____________________vary from A to B______________________29.height[]n.____________________adj.高的in height__________________30.absolutely[]adv.______________31.fantastic[]adj._________________32.fog[]n._____________33.cause[]vt._______________n.___________course n.____________________34.heat[]n._________vt.__________________adj.热的___________adj.热烈的35.wave[]n.______________vt.____________36.surroundings[]n.____________surround vt.___________surrounding adj.____________be surrounded by/with________________37.foresee[]vt____________(foresaw,foreseen)38.potential[]n.___________adj.____________39.guarantee[]vt.&n.__________________40.safety[]n.________safe adj.________n.________save vt.________,________,________41.unconscious[]adj.__________________conscious adj.___________42.anxiety[]n.__________________________adj.焦虑的，急切的be anxious about___________________be anxious for sth./to do sth.______________________43.drop[]n.__________vi.___________a drop of_______________drop in on sb._______________drop in at sp.________________44.panic[]n.&vi._______________(panicked,panicked)in panic_________________45.tremble[]n.&vi._________________46.put on_______________put down___________________put away________________put aside______________put forward_________________put out________________47.protective[]adj.___________________vt.保护___________n.保护48.suit[]vt.___________n.____________a suit of__________________49.helmet[]n.__________50.eventually[]adv.______________51.make one’s way to____________push one’s way___________fight one’s way______________52.even though/if__________________as if/though____________________53.precious[]adj.______________54.equipment[]n._____________equip vt.___________be equipped__________装备着55.document[]n._____________56.burn[]vt.&vi._____________burn sth.to the ground________________句型透视1.having done表示先于主句动作之前完成的行为_________________________________________(收集和评估完这些信息之后),I help other scientists to predict where lava from the volcano will flow next and how fast.2.be about to do...when...刚要……这时……I________________(刚要)go back to sleep_____(这时)suddenly my bedroom became as bright as day.3.独立主格结构The other two climbed down into the crater to collect some lava for later study,but _________________________________(这是我的第一次经历),I stayed at the top and watched them.4.It is said that...据说……_________________(据说)this boy,who had a great gift for languages and persuasion,is the father of the Manchu people.选用句型透视中的句式仿写句子(1)受到老师的批评后,他不再迟到了。

Unit5 (第5课时)【学习目标】掌握现在分词做状语的用法【重点难点】学生进行发现式学习，体验并归纳现在分词的类型以及在实际生活情景中的运用。

【学情分析】让每位学生利用自主学习或小组讨论掌握所学知识。

【导学流程】自主学习内容一、回顾旧知：1、be anxious to do sth. be anxious for/about sb./sth.be anxious for sb.to do sth.be anxious that...(that从句用虚拟语气，即谓语动词用“should＋动词原形”，其中should可以省略)2、n．忧虑，担心；渴望焦虑地二．基础知识感知：Having answered the letter, she went on to read an English novel.Having been shown the lab, we were taken to see the library.三、探究问题:.动词-ing形式的时态、语态及意义学习-ing形式作状语的用法时,需要注意以下四点:一、与过去分词作状语的区别。

一般来说,-ing形式表示主动、进行;过去分词表示被动、完成。

试比较:The enemy fled in a panic, leaving behind a lot of dead bodies and weapons.Defeated and frightened, the enemy fled in a panic.分析:前一例中的-ing形式短语在句子中作伴随状语,它与其逻辑主语the enemy之间为主动关系;后一句中的过去分词defeated和frightened表原因,它与其逻辑主语the enemy之间为被动关系。

二、分词(短语)作状语时，其逻辑主语必须与句子的主语一致。

如果不一致，必须用独立主格结构来表示，也就是在分词前面加上它的逻辑主语。

1. Comparing all the great people with each other, you’ll find that theyhave much in common.2. Finding her car stolen, she hurried to a policeman for help.3. The train having gone, we had to wait another day.分析:前两例中,-ing形式的逻辑主语均为主句的主语。

连词成篇Unit 5. The Power of NatureA Volcano EruptionAs the best candidate, I was appoint ed to collect and evaluate information for a database about diverse natural disaster s, such as hurricane s, typhoon s or thunderstorm s. Sometimes I did this by giving out questionnaire s to those who went through them. But sometimes I had to go through actual disasters myself. The Musaki Volcano was one of them.At that time, I lived in a bungalow alongside the volcano with a novelist, who came for the appreciation of its eruption. One day, when I was draw ing diagram s on the balcony and he was bath ing inside, the volcano erupt ed unexpectedly. The ash and lava fountain s shoot ing highly in the sky varied from 50 to 100 meters in height. It was absolutely fantastic! I even noticed a rainbow appear in the fog cause d by a heat wave.But, glanc ing through our surrounding s, I foresaw the potential danger and found no guarantee of our safety. The uncomfortable gas almost made us unconscious. Sweat s of anxiety began to drop. Managing to stop panic king and trembl ing, we quickly put on our protective suit s, helme ts and boots and eventually made our way to a safe place.
