What does the future hold for the problem of housing? A good deal
depend, of course, on the meaning of 'future'. If one is thinking in S1.______
term of science fiction and the space age it is at least possible to assume S2.______
that man will have solved such trivial and earthly problems as houses. S3.______
Writers of science fiction have had little to say on the subject. They have
conveyed the suggestion that men lived in great comfort, with every S4.______
conceivable gadget(小器具) to make life smoothly, healthy and easy. But S5.______
they have not said what his house will be made up. S6.______
Perhaps some new building materials, as yet unimagined, will have
been discovered or invented; at least one may be certain that bricks and
mortar(灰泥) will long have out of fashion. Scientists have already S7.______
pointed out that unless something is done either to restrict the world's rapid
growth in population or discover and develop new sources of food, millions S8.______
of people will be dying of starvation or, at best, suffering from underfeeding
by this century is out. But nobody has yet worked out any plan for S9.______
housing these growing populations. Admittedly, the worst situations will
occur in the hottest parts of the world, there housing can be of light S10.______
structures, or in backward areas where standards are traditionally low.
