“Wonderworld” will provide a covered area for people to live in with special air supply. (2) How can “ Wonderworld” make sure there is enough water?
“Wonderworld” will make sure there is enough water by collecting some from under the planet’s surface. After use, this water will be cleaned and recycled so that it can be used as rain to water crops and provide clean drinking water. Everyone will put their dirty water in special tanks and animals will have to go to the toilet in special places. Bacteria will clean this dirty water so it can be used again.(3) What is the advantage of living in “Wonderworld”?
People may become rich or famous.(4) Do you think people will be healthy
living in “Wonderworld”? Why?
I think the people will be quite healthy as they have a satisfactory climate, enough water and sufficient accommodation to live comfortably.Listening (P55) □ flying boots

2. How will you deal with the problems that you meet, if you are the designer of the undersea city? No noise from the air machines.Steel gates to the city wouldn’t open.solidcityworriedbackupwrongeitherseriousno noise from the air machinescity doors would not openbroken screenair machines not workingreplaced itnone as doors opened when air machines repaired Write an advertisement of the kind of quilt according to the listening material given.HomeworkSpeakingWork in pairs to think of some benefits
and problems in the future. Talk and write
about what life may be like on the earth in
1000 years’ time. Follow these steps.
In pairs prepare 4 to 5 questions about the future.
Ask an answer questions using the following expressions. Get together with another pair. Hold a
discussion and make notes of their
answers.Suppose that …. I wonder if ….
I imagine that …. I’m sure ….
Perhaps/Maybe/ Possibly ….
Most likely …. Probably ….
Do you imagine that ….?
Is it likely/ unlikely that ….?
Is it possible that ….?
Do you suppose that ….?Suggested questions:
Suppose you would change something in your hometown, what would it be?
I wonder how your hometown can achieve a really good quality of life?
What do you suppose is most important to keep for future generations?Sample dialogueS1: What problems do you think our
hometown will have 1000 years in the
future?
S2: Is it possible life will be better than it is
now?
S1: Yes, of course. Probably everyone will
be more comfortable. They’ll be
provided technological improvements
and the robots.S2: Oh I see. Is it possible that people will
have solved the problems of today-
global warming, air and water
pollution, etc?
S1: Most likely they will. For example,
dirty air. It would be easy to solve that.
All you would need to do is build a
cover over the city. All the air inside
would be kept clean.S2: That sounds fine but is it likely the
temperature will be too hot for us to live
on the earth?
S1: Maybe, but I’m sure someone will have
invented clothes with cooling systems
fitted into them. Perhaps everyone will
have a machine which pushes water
round the body and keeps you cool.
S2: Wow! Can you imagine what life will be
like when the energy runs out?S1: Oh, that will be solved by using the
energy from the sun. Don’t worry.
I’m sure we’d enjoy a visit if we
could ever visit the future! And now
we’ve had our four questions. Let’s
find another pair to discuss their
questions.Thanks for listening!
