Writing
1. Choose one of the natural disasters or any other disaster you have experienced.

1:00pm we were completely lost

A possible version:
Jane and I had been waking in the mountains when we noticed some dark clouds coming down the mountain. We decided to turn around and go home.
As we walked the clouds got nearer and nearer and the day grew darker. Then all of a sudden it began to snow. It was soon snowing so hard we couldn’t see very far in front of us. Holding each others’ hands so we couldn’t get separated, we continued down the mountain. Butthe snow got deeper and deeper. Walking became harder and harder. We began to get very tired and very frightened.
After a while the path became buried under the snow and we didn’t know which way to go. We were completely lost. We found some shelter behind a big rock. Hugging each other for warmth, we stayed like that until the storm was over. Luckily it only lasted an hour or two. Then the sun came out again and we could see our house in the distance. We were so relieved we both burst into tears.

Looking carefully at the ground, I made my way to the edge of the crater.
Having experienced quite a few earthquakes in Hawaii already, I didn’t take much notice.
Having + past participle (the perfect –ing form) to refer to an action that took place before the time expressed by main verb.

6. Set Exercise 3,4 and 5. check answers after each exercise and discuss reasons for

7. 小结-ing 形式的用法
–ing 形式作状语
用法 例句
时间 Walking along the street, I met Mary. (= While I was walking along the street….)在街上走的时候，我遇到了玛丽。
条件 Turning to the left, you will find the school. (= If you turn to the left, ….)向左走，你就会找到那个学校
让步 Knowing where I live, he never come to see me .(= Though he knows where Ilive, ….)尽管他知道我的住处，但从不来看我。
伴随 I stood there, waiting for her. (= …, and waited for her.)我站在那儿等她
原因 Being tired , I stopped to take a rest. (= Because I was tired, ….)因为疲倦，我停下来休息。
结果 It rained heavily, causing severe flooding in the area.(= It rained heavily so that it caused severe flooding in the area.)在这个地方雨下的如此大，以至引发了洪灾。
–ing形式的完成式
. 使用-ing形式需注意的几个问题:
.①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。
My wife had a long talk with Sally, explaining why she didn’t want the
children to play together我妻子与莎莉谈了很长时间，解释她为什么不想让
孩子们在一起玩。(现在分词explaining是句子主语my wife做的动作，它
们之间是主动关系,即explaining的逻辑主语，就是句子的主语my wife 。)
The train having gone, we had to wait another day.（the train逻辑主语 +
having gone 既为独立主格结构）
②分词短语做状语时，前面可以加上连词或 介词，但是分词短语和句子之间不能用并列连词(如but，and)，因为并列连词接的是两个并列成分，而分词短语只是全句的一个状语部分。分词和主句之间可用逗号。
例如:
误: Having been told many times，but he still couldn’t understand it.
正: He was told many times, but he still couldn’t understand it.或
Having been told many times， he still couldn’t understand it.
③-ing的一般式和完成式现在分词都可以表示先后接连发生的动作。在可能引起误解的场合应该用完成式现在分词表示先发生的动作。
例如:
Opening the drawer，he took out his wallet. (=He opened the drawer and took
out his wallet.)他打开抽屉，拿出钱包。
Coming into the room，he put down his bag. (=he came into the room and put
down his bag.)他走进房间，放下提包。
Having brushed his teeth，Mr. Brown came downstairs for breakfast.
布朗先生刷过牙，就下楼来吃早饭。 (此句如写成:Brushing his teeth,
Mr. Brown came downstairs for breakfast.可能指“边刷牙，边下楼’。
④分词的否定形式是在分词短语前面加上 not, never等否定词构成。
例如:
Not fearing the fire, the child touched and got a finger burnt.
小孩儿不知道怕火，用手去摸，把手指烫了。
Not knowing how to find the subway, I asked a policeman for help. 我不知道怎
样找到地铁，就去找警察帮忙。
(Having been)+p.p. …, 主语+谓语
被动
主动
Having finished my work, I went home. (= After I had finished my work, ….)工作做完只后，我就回家了。
例句
–ing形式的完成式所表示的时间在谓语动词之前
表示被动可直接用过却分词
用法
Having +p.p. …, 主语+谓语

III．教材分析
本单元以the power of nature 为话题，旨在通过本单元教学使学生了解火山爆发，地震，台风，洪水，海啸等自然现象，认识到自然的伟大力量，并会用所学词汇描述在经历自然灾害时的感受，思考人类应对自然灾害的态度和方法，提高自我保护意识。
Warming up 通过对火山爆发示意图的探讨激活学生了解与本单元话题相关的背景知识，而后通过讨论人类应对自然灾害的措施引发学生对本单元话题的思考，激发学生的求知欲，为随后进行的听说读写打下基础。
Pre-reading 通过回答问题测试自己是否适合作火山学家，让学生了解这一陌生职业，为阅读做好准备。
Reading 部分一味火山学家以第一人称的形式讲述了自己的工作及第一次目睹火山爆发时的情景和心情，描写了人与自然的斗争与和谐相处的乐趣，使学生认识到火山是美丽的，
但同时极具破坏力，而火山学家的工作可以减少由火山引发的损失。
Comprehending 设计了两种题型：第一题要求学生在阅读后发表对火山学家这一职业的看法；第二题检测学生对文章细节的理解。
Learning about language 分为词汇和语法两部分。词汇部分着重从词的意义用法和表达方
面对学生学习词汇给予指导；语法部分学习-ing形式在句子中作状语表原因，时间及结果。
Using language 以语言实践为目的，包括四个部分的内容。Listening 三位火山学家
讲述了他们各自最惊险的一次经历。学生在练习听力的同时学会描述害怕和紧张的词汇。
Speaking 是listening 的延续。要求学生讲述自己类似的经历，同时在运用中巩固单词。
Reading 介绍了旅游胜地the lake of heaven， 培养学生快速获取信息的能力。Reading
与writing 属于同一话题，要求根据所给信息写一篇介绍hot springs 的作文。
Sunning up部分要求学生就火山，火山学家，天池，本单元词语，-ing形式和表达情感的日常交际用语等方面进行自我评价，判定呢感学习情况。
learning tip 部分介绍单词记忆方法：利用构词法或话题分类记忆单词；利用图表，图片等记忆单词；随身携带生词本；多说多写。英语：Unit5《The power of nature》教案（5）（新人教版选修6）
