教学内容分析
This is the first teaching perid f this unit.The central part f this perid is the reading passage with the title f “The Earth Is Becming Warmer—But Des It Matter？” talking abut the glbal issue which has a great effect n human beings' life.
Warming Up gives six pictures t help students list the surces f energy they can think f in ur daily life.Then they will be led t discuss which energy surce is “renewable” and which is “nn－renewable”．This part is designed t help the students t recall their backgrund knwledge abut energy and prepares students fr the whle unit.
Pre－reading prvides a picture f a greenhuse and then tells us what a greenhuse is and what “greenhuse gases” are.The students will be led t discuss what they think greenhuse gases d，leading t the tpic f the reading passage.
Reading is a passage frm an envirnmental magazine fr yung peple.It puts frward the pssible effect f increased carbn dixide in the atmsphere and different pints f view abut it.It als analyzes the causes f the earth's increased temperature.It pses questins and encurages students t think abut the issues.There are tw graphs in it that tell us the “temperature difference frm lng－term average,1860－2000” and “carbn dixide cntent in the atmsphere,1957－1997”．Characters in the passage—Dr Janice Fster，Gerge Hambley and Charles Keeling are all real persns and their views reflect the views f sme scientists tday.
Cmprehending cnsists f three written r ral exercises fr the students t d s as t help the students t get a better understanding f the text，that is t say，t help the teacher t check hw much the students have understd the text.

eq \(\s\up7(),\s\d5(教学过程))
Step 1 Warming up
1．Warming up by reading and talking：
Read thrugh the exercise with the class.Put students in grups f fur t talk abut what we use energy fr，what are the surces f these energy and whether the surces are renewable r nn－renewable.
Suggested answer：The six phts are：windmills；a cal pwer statin；an il refinery；a nuclear pwer plant；slar panels；a hydr－electric dam.
2．Warming up by discussin：
Draw a frm n the blackbard as fllws：
Let the students have a discussin and cllect suggestins frm students and write them under the apprpriate heading.
Suggested answer：
Step 2 Pre－reading
1．Shw a picture f a greenhuse t students and ask them what a greenhuse is made f and what its purpse is.
Suggested answer：It's made f glass and plants can grw in it when it's cld utside.
Ask the students hw it wrks.
Suggested answer：The glass traps the heat frm the sun，making the air warm s that plants grw better.
2．Ask students what they think “greenhuse gases” are and what they think greenhuse gases d.Lk at the picture abve and explain it t their partners.
Suggested answer：Greenhuse gases perfrm the same functin as the glass in a glasshuse：they trap the heat f the sun and keep the air surrunding the earth warm.This is called the greenhuse effect.)
Step 3 Reading and cmprehending
1．Fast reading
Ask students t read the passage quickly s as t get the key wrds and general idea f each paragraph and answer the fllwing questins：
(1)What is the main tpic f the article?
________________________________________________________________________
(2)Wh wrte the magazine article？What is the name f the magazine?
________________________________________________________________________
(3)What are the names f the three scientists mentined in the article？D they agree with ne anther?
________________________________________________________________________
Suggested answers：(1)Glbal warming/the warming f the earth.(2)Sphie Armstrng，Earth Care.
(3)Dr Janice Fster，Charles Keeling，Gerge Hambley.They dn't agree with each ther.
2．Detailed reading
(1)Read the passage carefully and judge whether the statements are true(T) r false(F)．
①Janice Fster believes that glbal warming is caused by the burning fssil fuels.( )
②Natural gas is a greenhuse gas.( )
③Carbn dixide is a byprduct f burning fssil fuels.( )
④Peple accept Charles Keeling's data because he tk accurate measurements.( )
⑤Flding culd be ne f the effects f future glbal warming.( )
⑥Gerge Hambley believes scientists are just guessing abut the effects f glbal warming.( )
⑦Gerge Hambley is wrried abut the effects f carbn dixide n plant grwth.( )
⑧It is clear what the effects f glbal warming will be.( )
(Suggested answers：TFTTTTFF)
3．Structure analyzing

Abut Glbal Warming(关于全球变暖)
Glbal warming is the increase in the average temperature f Earth's near－surface air and ceans since the mid－20th century and its prjected cntinuatin.Glbal surface temperature increased 0.74±0.18℃(1.33±0.32)between the start and the end f the 20th century.The Intergvernmental Panel n Climate Change(IPCC)cncludes that mst f the bserved temperature increase since the middle f the 20th century was very likely caused by increasing cncentratins f greenhuse gases resulting frm human activity such as fssil fuel burning and defrestatin.The IPCC als cncludes that variatins in natural phenmena such as slar radiatin and vlcanic eruptins had a small cling effect after 1950.These basic cnclusins have been endrsed by mre than 40 scientific scieties and academies f science，including all f the natinal academies f science f the majr industrialized cuntries.
Climate mdel prjectins summarized in the latest IPCC reprt indicate that the glbal surface temperature is likely t rise a further 1.1 t 6.4℃(2.0 t 11.5)during the 21st century.The uncertainty in this estimate arises frm the use f mdels with differing sensitivity t greenhuse gas cncentratins and the use f differing estimates f future greenhuse gas emissins.Mst studies fcus n the perid up t the year 2100.Hwever，warming is expected t cntinue beynd 2100 even if emissins stp，because f the large heat capacity f the ceans and the lng lifetime f carbn dixide in the atmsphere.
An increase in glbal temperature will cause sea levels t rise and will change the amunt and pattern f precipitatin，prbably including expansin f subtrpical deserts.Warming is expected t be strngest in the Arctic and wuld be assciated with cntinuing retreat f glaciers，permafrst and sea ice.Other likely effects include changes in the frequency and intensity f extreme weather events，species extinctins，and changes in agricultural yields.Warming and related changes will vary frm regin t regin arund the glbe，thugh the nature f these reginal variatins is uncertain.
Plitical and public debate cntinues regarding glbal warming，and what actins(if any)t take in respnse.The available ptins are mitigatin t reduce further emissins；adaptatin t reduce the damage caused by warming；and，mre speculatively，geengineering(地球工程)t reverse glbal warming.Mst natinal gvernments have signed and ratified the Kyt Prtcl aimed at reducing greenhuse gas emissins.
