31、n City?The floating island includes 4 parts as followed:a hotel with many rooms for families to relax while their bodies return to normal;a large classroom with all kinds of educational aids for children of school age;a huge sports stadium;a very big hall for entertainment.This passage is written in

32、 the style of an advertisement to sell houses under the sea.As people are not used to living under the sea,the company must encourage people to move there by giving them some extra advantages.Writing Style The aim of this task is for students to imagine what it would be like to live under the sea:it

33、s advantages and disadvantages.The name,Saturation City,comes from science.After people have stayed for some time under the water they need to come up to the surface.They are“saturated”or have stayed as long as their health will allow.At the moment it is difficult to stay for one full day under wate

34、r except under special conditions.In Key Largo,Florida,scientists have devised an undersea laboratory,which means that people can live and work under water for up to ten days at a time before returning to the surface.By the year AD 3008 it will undoubtedly be possible to stay under water even longer

35、.Living underwater is similar to going into space.Both affect the human body badly.In space,the lack of gravity makes a person grow taller and his/her bones become more brittle.Under water,the pressure pressing down on the person is too great.So,people living underwater have to come back up to the s
