III．教材分析

本單元以the power of nature 為話題，旨在通過本單元教學使學生了解火山爆發，地震，臺風，洪水，海嘯等自然現象，認識到自然的偉大力量，并會用所學詞匯描述在經歷自然災害時的感受，思考人類應對自然災害的態度和方法，提高自我保護意識。

Warming up 通過對火山爆發示意圖的探討激活學生了解與本單元話題相關的背景知識，而后通過討論人類應對自然災害的措施引發學生對本單元話題的思考，激發學生的求知欲，為隨后進行的聽說讀寫打下基礎。

Pre-reading 通過回答問題測試自己是否適合作火山學家，讓學生了解這一陌生職業，為閱讀做好準備。

Reading 部分一味火山學家以第一人稱的形式講述了自己的工作及第一次目睹火山爆發時的情景和心情，描寫了人與自然的斗爭與和諧相處的樂趣，使學生認識到火山是美麗的，

但同時極具破壞力，而火山學家的工作可以減少由火山引發的損失。

Comprehending 設計了兩種題型：第一題要求學生在閱讀后發表對火山學家這一職業的看法；第二題檢測學生對文章細節的理解。

Learning about language 分為詞匯和語法兩部分。詞匯部分著重從詞的意義用法和表達方

面對學生學習詞匯給予指導；語法部分學習ing形式在句子中作狀語表原因，時間及結果。

Using language 以語言實踐為目的，包括四個部分的內容。Listening 三位火山學家

講述了他們各自最驚險的一次經歷。學生在練習聽力的同時學會描述害怕和緊張的詞匯。

Speaking 是listening 的延續。要求學生講述自己類似的經歷，同時在運用中鞏固單詞。

Reading 介紹了旅游勝地the lake of heaven， 培養學生快速獲取信息的能力。Reading

與writing 屬于同一話題，要求根據所給信息寫一篇介紹hot springs 的作文。

Sunning up部分要求學生就火山，火山學家，天池，本單元詞語，-ing形式和表達情感的日常交際用語等方面進行自我評價，判定呢感學習情況。

learning tip 部分介紹單詞記憶方法：利用構詞法或話題分類記憶單詞；利用圖表，圖片等記憶單詞；隨身攜帶生詞本；多

說多寫。

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.

4. Read and discuss Exercise 1 in the SB

5. Set Exercise 2. check answers and discuss structures.

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

the structures used.

7. 小結-ing 形式的用法

1) –ing 形式作狀語

用法 例句

時間 Walking along the street, I met Mary. (= While I was walking along the street….)在街上走的時候，我遇到了瑪麗。

條件 Turning to the left, you will find the school. (= If you turn to the left, ….)向左走，你就會找到那個學校

讓步 Knowing where I live, he never come to see me .(= Though he knows where I

live, ….)盡管他知道我的住處，但從不來看我。

伴隨 I stood there, waiting for her. (= …, and waited for her.)我站在那兒等她

原因 Being tired , I stopped to take a rest. (= Because I was tired, ….)因為疲倦，我停下來休息。

結果 It rained heavily, causing severe flooding in the area.(= It rained heavily so that it caused severe flooding in the area.)在這個地方雨下的如此大，以至引發了洪災。

2) –ing形式的完成式

2) . 使用-ing形式需注意的幾個問題:

.①分詞(短語)作狀語時，其邏輯主語必須與句子的主語一致。如果不一致，必須

用獨立主格結構來表示，也就是在分詞前面加上它的邏輯主語。

My wife had a long talk with Sally, explaining why she didn’t want the

children to play together我妻子與莎莉談了很長時間，解釋她為什么不想讓

孩子們在一起玩。(現在分詞explaining是句子主語my wife做的動作，它

們之間是主動關系,即explaining的邏輯主語，就是句子的主語my wife 。)

The train having gone, we had to wait another day.（the train邏輯主語 +

having gone 既為獨立主格結構）

②分詞短語做狀語時，前面可以加上連詞或 介詞，但是分詞短語和句子之間不能用并列連詞(如but，and)，因為并列連詞接的是兩個并列成分，而分詞短語只是全句的一個狀語部分。分詞和主句之間可用逗號。

例如:

誤: 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的一般式和完成式現在分詞都可以表示先后接連發生的動作。在可能引起誤解的場合應該用完成式現在分詞表示先發生的動作。

例如:

Opening the drawer，he took out his wallet. (=He opened the drawer and took

out his wallet.)他打開抽屜，拿出錢包。

Coming into the room，he put down his bag. (=he came into the room and put

down his bag.)他走進房間，放下提包。

Having brushed his teeth，Mr. Brown came downstairs for breakfast.

布朗先生刷過牙，就下樓來吃早飯。 (此句如寫成:Brushing his teeth,

Mr. Brown came downstairs for breakfast.可能指“邊刷牙，邊下樓’。

④分詞的否定形式是在分詞短語前面加上 not, never等否定詞構成。

例如:

Not fearing the fire, the child touched and got a finger burnt.

小孩兒不知道怕火，用手去摸，把手指燙了。

Not knowing how to find the subway, I asked a policeman for help. 我不知道怎

樣找到地鐵，就去找警察幫忙。

The fifth period Listening

Listen to three volcanologists talking about frightening experience in their work life. The texts model ways to express feelings of anxiety and fear.

1. First listening

1) Set Exercise 1. Remind students that they are required only to listen to names

of the three scientists and to try to understand the gist of each recount.

2) check answers. Ask students to recall what happened to each speaker, in

general terms only, they are not expected to remember details at this stage.

2.Second listening

1) This time students will be listening for details. Stop the tape after each speaker

and give students time to write their answers. Check answers before moving to

the next speaker.

2) At this point, you could ask students work in groups of three, each taking the role of one of the volcanologists and recounting the story to others in the group. Before

they start, ask them for some useful expressions to talk about fear and anxiety. Write these

on the board and suggest students use these in their recounts.

Eg: I was very worried that…

I was trembling …

I was still terrified.

I was so nervous that …

I was so anxious that…

3.Third listening

This time the students are listening for a different kind of detail. They must listen

for the expressions listed in Exercise 3 in order to identify who said what. These

sentences model ways of expressing fear and anxiety.

1) Having individual students read the sentences aloud to the class. Ask them to try to recall who said each one. Ask them to write their guesses in their books in

the left-hand margin beside the expressions.

2) Play the tape for students to identify the expressions and record the name of the

speaker in the SB. It may be necessary to play the tape more than once. Check

answers by playing the tape and stopping when one of the expression is heard.

3. Ask students to check how many of their guesses were correct. The aim of this is to build students confidence by showing them how much they had understood even before they consciously listened for these expressions.

4. Ex: speaking

Think of a powerful natural force (such as an earthquake, flood, typhoon, storm) that you have experienced. You can use your imagination if you have not experienced any of these things. Tell your partner about your experience and how you felt. Use expressions from Exercise 3 in listening as well as other words and expressions you and your partner have thought of..

The sixth period Using language

This reading passage is written as though it is from a tour guide. It describes some of

the tourist attractions in Changbaishan in Jilin provinc.

1. Ask students to read the title of the passage and then ask whether they have heard of this lake. Spend a few minutes eliciting students’ prior knowledge about

Changbaishan.

2. Read the questions before reading passage and ask students to read through the passage as quickly as possible.

Changbaishan is the second largest nature reserve in China. (F)

The peak of Changbaishan can reach as high as 2,000 meters. (T)

You can see a lot of black bears, leopards or cranes in Changbaishan. (F)

Tianchi is a lake in the crater of an extinct volcano. (T)

The ancestors of the Manchu people were believed to be good at language and persuasion. (F)

3. Read the questions that appear before the reading passage. As going through each

question discuss which key words are and have students underline them. Point out

that they do not need to understand every word in the passage in order to find the

answers. Instead, they should scan the text quickly looking for underlined keywords in the questions. Once they find a sentence containing a key word, they can read more slowly to see if that sentence contains the answer.

4. Check answers.

5. some explanations:

The height of the land varies from 700 metres above sea level to over 2,000 metres

and is home to a great diversity of plants and animals.

這里的地面高度從海拔700米到2，000多米不等， 是各種各樣的動植物的生長地。
