Teaching Procedures：
Step I Greetings
Greet the whole class as usual．
Step II Warming up
(Show some beautiful pictures to the students.)
T: Look at these pictures. How beautiful they are! Do you want to pay a visit to
these places?
Ss：Yes．
T：But in some places，it’s not so beautiful Look at the pictures．please．
(Show the following pictures .)
T：What can you see in the pictures?
S：1 can see a river，which is polluted．The river water is very dirty．
S：I can see smoke coming from many chimneys，and the air is dark．The air is polluted．
T：Good．Which problem do you think is the biggest one facing the earth?
S：I think it is the water pollution．
T：Why do you think so?
S：Because if water is polluted．People will not be able to get clean water to drink；
therefore，many people will get sick．It’s terrible．
T：Very good．Who has a different opinion?
S：I think the air pollution is the biggest problem．Because if the air is polluted， there will not be clean air for us to breathe．Everybody will get terrible diseases．
T：Quite right．Now，who can tell us what causes these problems?
S：I think it is because people pay no attention to our environment．They pour
waste water into rivers，1akes and seas without cleaning it．
S：The air pollution is caused by the factories．People build factories to develop
the industry，but they never pay attention to controlling the pollution．The
harmful smoke should be made harmless before it goes into the air，but few
factories would like to do so because this will cost much．
T：Very good．Now，who knows what we can do to solve these problems?
S：I think our government should pay more attention to environmental protection．They should check the factories as often as possible to make sure they don’t pour waste water into rivers or lakes and make sure they don’t let
harmful smoke go into the air．
T：Good idea．Now，please open your books and turn to Page 65．There are six pictures in Warming up．We have just talked about two of them．Now，work in groups of four to talk about the other pictures．Answer the questions below the pictures．
(A while 1ater，ask some students to act out．)

The problems the earth is facing

Step III Preparation for Listening and
T：Very good．I think you’ve known something about our environment.
Now，please turn to Page 66．Look at the picture in Listening．What can you see?
Ss：A person is making a speech to the audience．
T：Can you guess what speech she is giving?
Ss：Maybe about our earth．
T：OK．Now，let’s listen to the tape．I’ll play it twice for you．Listen carefully
to answer the questions in Part 1．
(Play the tape twice for Ss to listen and write down their answers．Then ask some students to read out their answers．Check with the whole class．The teacher says the following．)
T：Good．You’re done very well． But from the passage we know that she hasn’t finished her speech．What do you think she wi1l say next? Have a short discussion in pairs．please．(Ss have a short discussion and then the teacher asks one or two pairs to say their answers．)Well done．Now．1et’s listen to the second part．Listen carefully to outline the speaker’s two arguments. Fill in the table in Part 2．Are you ready?
Ss：Yes．
T：OK．Let’s begin．
(Play the tape twice for Ss to Listen and write down their answers．Pause the tape if necessary. Then ask several students to read out their answers．)
T：Now，let’s listen to the tape again to check your answers．(Play the tape once more and then check the answers with the whole class．)Good．P1ease think a bout what the speaker will say next．You call use what you have heard on the tape to predict what will come next．Make an outline like the one in the table and then write down what you think the speaker will say．You can work in pairs or groups of four as you like．
(A moment 1ater，ask some students to read out their paragraphs and compare different speeches to choose the best one．)
Step Ⅳ Speaking
T：Well done! We’ve talked much about pollution．We know that pollution is a big problem facing the earth．But why can’t we stop the pollution? Why doesn’t our government shut down the factories that pollute the environment badly? Who knows?
S：I think our government must have its own opinion．Maybe they think the factories are more important than the environment．Because the government can get lots of money from factories．If they shut the factories down ,it will not be able to get so much money．And this is not good for the development of the city or town.
T：Yes．Different people have different opinions．They may not agree with one another．So sometimes it’s very hard to make a decision and to make a change．For example，we know that coal is a valuable resource that can be used to produce energy，but it also causes serious pollution．What should we do with it? (Ss may have various answers．) You see，you don’t agree with each other．Now，we need to have a meeting to discuss this problem．Please work in groups of five．You should play different roles：a businessman．a scientist. a local citizen，an environmentalist and a local leader．Different people have different opinions．
(Every person has his／her own opinion．) Please discuss the issue first and
then the local leader should summarise and make a decision．You can have a look at the table and the useful expressions in Speaking Part before you begin your discussion．They’re very helpful．
(Give the students enough time to have a discussion and then ask the students who play the role of the local leader to read out their decisions．Compare them and choose the best decision．)
Sample dialogue：
A：Today we are here to decide whether we should burn the coal．Please tell us
whatever you think．
B：I think we should burn the coal．1f we don’t burn it now，maybe it will be
useless in the future，New energy wi1l be used instead of coal，such as．solar energy．
C：But burning coal causes too much pollution to our environment．1t pollutes the air badly. If nothing is done to stop its pollution to our earth，then we will
Have no fresh air to breathe．
D：Yes，I quite agree．I think we shouldn’t burn the coal now. It would be better
if we spend more money on science to find a better way of using the coal．Once
we know how to burn it with out polluting the environment ,we can make full use of it．
E：That sounds quite reasonable，but it’s clear that if we want to develop our area as soon as possible，we need money．How can we get money? We can only burn the coal to make the factories work to make money．If we stop using the coal now ,how shall we continue our production and development?…
A：OK．All that you said are reasonable．I believe that we must try our best to
find a better way to use the coal．Meanwhile ,we must make sure that the factories which burn the coal take measures to stop polluting the environment．
Step V Summary and Homework
T：Well done．After class，please write down your dialogue in your exercise book．Today．we’ve talked about our environment．We know that there are some big problems facing our earth．We must try to do what we can to protect the earth．Besides，we’ve practiced supporting an opinion．Who can come to the blackboard and write down the useful expressions we’ve practiced just now?
(A student writes them down on the blackboard．If this student can't write all of them，the teacher may ask another student to write the other expressions．)
T: Very good．After class, you need practise more to master them better. That’s a11 for today．See you tomorrow!
Ss：Se you tomorrow!

Teaching Procedures
Step one:（7minutes）
Enjoy a song from Jackson ------Heal the World before the class.
Step two: lead in (5minutes)
T: Before our class I will take you to some beautiful places.
(Show the students a beautiful picture)
T: Do you want to pay a visit to this place?
S: Yes!
T: I suggest you be quick, because many years later things will be like this…
(Show them another picture )
T: Everything is in disorder. Tell me something more in detail about the problems that we are now facing.
Group competition
T: Now I divide the whole class into two groups. Anyone of you is expected to stand up to talk about the problems that the human beings are facing. At the end of the competition the one who think of more problems will win the competition and will be given some small gifts.
(After the competition)
T: You have done a good job! And I will show you more about the serious problems.
(Show them pictures about air pollution, deforestation, water pollution, poor sanitation, wars, starvation, poverty, lack of education)

Step three: new words (4minutes)
(While explaining, show them the related pictures that will leave a deeper impression on the students)
T: There are so many problems. What should we do? The head leaders are worried about this too. So they sat together to talk about the solutions. We call the conferences they attend summits. Meanwhile we call the top part of a mountain a summit. The head leaders from all over the world at the summit are representatives. They are talking about the problems, and most of the problems are in rural areas. Most rural arrears are in poverty. If they still remain in poverty, there will be more violence. So our premiers are worried about this. They hope our country prospers and they also hope we can live in harmony with nature.
T: These are all the new words we will meet in the reading passage. Together read after me.
(Teach them to read all the new words and make sure that they can pronounce them correctly and know the meaning of them)

Step four: Pre-reading (3minutes)
