Step I Greetings and Lead-in
Greet the whole class as usual．
T: In the first period of this unit，we talked about our environment．We know that our environment is in great danger．It’s being seriously polluted．
What can we do to protect the environment?
S：We can help more people to know the importance of protecting our earth．
S：We should not use the things that pollute the environment，such as plastic bags，air-conditioners and so on．
S：…
Step Ⅱ Pre-reading
T：Very good．Today we’re going to read the passage “Welcome to the earth summit”．It is about the earth summit and some of the major problems facing the world．Before reading the text，try to predict its content．Work in pairs and write down what you think each part of the text will be about．
(Allow the students a few minutes to finish the task．Then ask some students
to say their answers．Compare the answers and choose the best of them．)
Step III Reading
T：Well done．Now, please read the passage quickly make the outline of the text．Compare it with the outline you made just now，F(xiàn)ind out how they are different from each other，Which one do you think is better? Are you clear?
Ss：Yes．
(Give Ss enough time to read the text，make the new outline and compare it with the one made in the Pre-reading．Finally, ask some students to answer the questions．Students may have various answers．)
Sample outline：
Introduction：Introduce the Earth Summit to the readers．Tell readers when and where it is first held and what it is about．
Body：Give more detailed information about the problems discussed at the meeting．
Conclusion：Tell readers what we can do to protect our earth．
T：Good．Now, please read the passage carefully．This time you should pay attention to some detailed information in the passage．After that，I'll ask you ,some questions．OK，you can begin．(Ss read for a while．) Have you finished?
Ss：Yes．
T：OK．Now，I’ll ask you some questions．
If you know the answer to each question，please stand up．Are you clear?
Ss：Yes．
T：OK．Listen to my first question．What are the “big three”?
S：I know the “big three” refers to contaminated drinking water，poor sanitation and air pollution．
T：Do you agree with him／her?
Ss：Yes．
T：OK．Who knows of any others?
S：I know．People hunt too many wild animals and birds and they cut too many trees．too．
T：Right．Why are conferences like the Earth Summit important?
S：Because they help people understand that there exist serious problems and that there’s still time to take action．They can tell us what we can do to help, too
T：Very good．Next question．What issues are discussed at the Earth Summit?
S： Contaminated drinking water，poor sanitation．air pollution，poverty．wars and violence．
T：Which do you think is the most important? Why?
S：I think the war is the most important, because wars not only cost too much money, destroy too many buildings，make people homeless，but also they make it difficult for the countries to develop further．Thus，life will be hard for people．especially for the poor．If people lire in peace，the development will continue and people’s life wil1 get better and better day by day．
S：But l think the protection of the environment is more important than wars．
Because if the environment is polluted，even if there’s not any war in the
world，people can’t live a happy or healthy life，either．
S：…
(Ss may have different opinions．)
T：OK．We know that the issues discussed at the Earth Summit are a11 very important．We should 1earn something from this passage and try to do what we can to protect our earth．Do you agree?
Ss：Yes．
