一、案例背景

近年來，世界各地自然災(zāi)害頻發(fā)、地震、海嘯、洪澇、干旱等自然災(zāi)害給人類造成巨大經(jīng)濟損失的同時，也給受災(zāi)害的人們心理上帶來了難以撫平的創(chuàng)傷。所以，設(shè)計本課的目的是為了讓他們充分認(rèn)識到保護(hù)環(huán)境的重要性。同時，在面對突發(fā)的自然災(zāi)害面前，能保持積極樂觀的精神狀態(tài)，從而做到從平時做起，從小事做起，來維護(hù)我們的家園———地球。而高中階段是中學(xué)生多變的階段，也是成型階段，教師應(yīng)該抓住這個階段學(xué)生的特點在教學(xué)中適時地進(jìn)行德育教育。

二、案例設(shè)計

1. 教材分析

本課是高一必修3第三模塊里的一篇閱讀課（Reading），出自外語教學(xué)與研究出版社出版的高中英語學(xué)生用書。在第一課Introduction里面初步接觸和了解了一些自然災(zāi)害和其危害。這一課Reading是上文的延伸。文中有三個小標(biāo)題，分別概括了各段的中心，并且可知文中主要介紹了兩個災(zāi)難和災(zāi)難造成的讓人不可思議的事件。

2. 學(xué)生分析

學(xué)生在接受這一內(nèi)容沒有多大的難度，因為近年世界各地災(zāi)難不斷，加上電視報紙的介紹和各地防御措施的采取，他們基本能了解一些災(zāi)難和危害。

3. 設(shè)計思路

本堂課采用任務(wù)型教學(xué)，通過這種活動和學(xué)習(xí)，學(xué)生的自主學(xué)習(xí)得到了加強，不再認(rèn)為英語的課堂學(xué)習(xí)很枯燥，而會主動參與到活動中，成為課堂的主體。同時也加強了與他人交流合作的能力，從而達(dá)到課堂活動目的。

三、案例實錄

Teaching Aims：

1. Master the important words and expressions.

2. According to studying the text， help the students to improve their reading abilities.

Teaching Importance：

1. Help them remember the words and expressions.

2. Help them understand the text and improve their reading abilities.

Teaching Difficulties：

1. How to remember the words and expressions.

2. How to learn to find the general ideas of the passage.

Teaching Methods：

brainstorming individual work pair work

Teaching Procedures：

Step I Lead-in

Do you remember the day when an earthquake happened in WenChuan， SiChuan Provice on May 12， 2008？

（Yes.） And it is frightening. Besides the earthquake is a natural disaster. Now can you tell me some other natural disasters？

（flood hurricane lightening sandstorm tornado thunderstorm and so on ）

Step II Pre-reading：

Today we will study some natural disasters. Before studying the text， lets get familiar with some new words.

1. Match the words in the box with their definitions in two minutes in pairs of two.

flood hurricane lightening thunderstorm tornado

（1）a lot of water in an area which is usually dry

（2）a very strong wind or storm

（3）a lot of rain falling quickly ， with loud noises and flashes of light

（4）the flash of light which happens during a thunderstorm

（5）a column of air that turns very quickly

After two minutes， let one student read his answers out loudly.

（flood； hurricane； thunderstorm； lightening； tornado）

Fast reading

Lets come to the text. There are three passages.

1. Look through their titles and the pictures quickly and match the passages with the general ideas.

Passage 1 A the hurricane， its power and the worst hurricane

Passage 2 B a story about the 1900 Galveston hurricane

Passage 3 C the tornado and its power

After a while ask a student to display his answers.

（Passage 1—C；Passage 2—A；Passage 3—B）

2. Read the text fast to answer the questions in one minute.

a. What is a tornado？

（A tornado is a rotating column of air from a thunderstorm to the ground.）

b. What is a hurricane？

（A hurricane is a strong tropical storm， and it usually occurs in the southern Atlantic Ocean， the Caribbean Sea and the Gulf of Mexico.）

These two questions are easy， so I let them answer them together.

Careful reading

This text has too many new words， so work in groups of four.

1. Try to understand the first two passages and fill in the blanks in ten minutes.

After ten minutes， let some students write their answers on the blackboard and correct their answers.

（1-column of air； 2-tropical； 3-400； 4—120； 5-the US； 6-southern； 7-trains； 8-feathers； 9-floods； 10-800； 11-six； 12-states； 13-deaths）

1. Ask some students to tell the story.

2. Let them do it together.

四、案例分析

在課堂教學(xué)中充分利用多媒體的優(yōu)勢，合理增加課容量，加大了練習(xí)力度，也加快了課堂的節(jié)奏。

1. 通過運用學(xué)生熟悉的話題導(dǎo)入，引起學(xué)生閱讀的興趣和欲望。2. 整個教學(xué)過程中，始終以由易到難、由淺入深為宗旨，設(shè)計了各種題型以適應(yīng)不同層次的學(xué)生，同時也練習(xí)了高考閱讀中常見的題型。3. 最后，通過討論讓學(xué)生對整篇文章的認(rèn)識又上升到一個更高的層次，即對他們進(jìn)行了很好的德育教育。

五、教學(xué)反思

整體感覺這節(jié)課上得比較成功，尤其是最后的兩個階段，可以說達(dá)到了最高潮。通過這節(jié)課，學(xué)生掌握了重要的單詞和短語（新教材更注重詞匯的學(xué)習(xí)），同時也提高了他們的閱讀理解能力和解題能力。但是學(xué)生的口語表達(dá)不太流利，還有待提高，這也是筆者今后努力的方向。
