22. 1. How can “ Wonderworld ” make sure there is enough oxygen? “ Wonderworld ” will provide a covered area for people to live in with a special air supply. 2 Listen to the tape again and answer the following questions.

23. 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 drops 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.

24. 3 What is the advantage of living in “ Wonderworld ” ? 4 Do you think people will be healthy living in “ Wonderworld ” ? Why? People may become rich and famous. I think the people will be quite healthy as they have a satisfactory climate, enough water and sufficient accommodation to live comfortably.
