Step I Warming up
Lead in the topic by discussing the possibilities of living under the sea. Encourage the Ss to use their imaginations.

3. In the undersea cities, what equipments do you think are necessary?
Ten minutes later, ask some Ss to answer the questions.
T: Have you finished? Who would like to tell us your opinion? Volunteer?
S: I think it’s possible. Maybe in the future scientists will invent some kind of equipment that makes it possible for human being to live under the sea.
T: If it is possible, where are you going to live under the sea? There is all water and fishes around you.
S: Maybe in a special equipment which will provide us much-needed oxygen and can float in the water. In that case we can travel in the sea to enjoy the wonderful view of the sea.
T: Good. If you are going to live under the sea, what kind of equipment do you think is necessary for your living?

Step Ⅱ Reading

Please turn to page 58 and read the passage RISING TO A CHALLENGE. Let’s see what the life will be like in this undersea city. When you finish reading, complete the sentences on the screen.
Give the Ss 3 minutes to go through the whole passage.
1. The undersea city is so comfortable that it is described as ___________ .
2. The undersea city has the following advantages:

T: Can you find out some suitable sentences or words to fill in the blanks? What are the advantages of living under the sea?

S: The undersea city has the following advantages:

c. complete personal security;
d. no housework worries.
T: That’s great. You all have got the general idea of the passage. Now let’s look into some detailed aspects of the undersea city. First let’s look at its contact with the land surface. Who would like to tell me at the very beginning, what kind of problem were they facing? And how was the problem solved?
S: The sea bottom is so deep that it’s hard to contact with the land surface. But later they invented the one-person or family shuttle-submarines which will always be ready to take people to the surface.
T: So in that case people who live under the sea can easily contact with the land surface. Then com-paring with living on land, what advantage do you think can attract people to live under the sea?
S: We can get twice as much personal space as in flats on land.
T: Good! Then what kind of special equipment will be provided so as to realize all the advantages? Please read the text again and finish the following chart. You can work with your partners.
