　　How to Solve the Housing Problem in Big Cities

　　Housing problem has become one of the biggest concerns for people in big cities. With the rapid development of industry and great increase in employment, more people are swarming into cities. Accommodations have become ever difficult, causing inconvenience to people's work and life.

　　Many proposals have been put forward to solve this problem. Some suggest that more high buildings be constructed. Some insist that the underground be developed. Others propose that satellite cities be built. Still others argue that cities should be expanded to move people to the suburbs.

　　Personally, I am in favor of building satellite cities in the suburbs. For one thing, these cities are not far away from big cities. It is still very convenient for people to go downtown as they wish. For another, the fresh air and adequate space there will be a great attraction for people who are living in crowded cities. If many people move to the satellite cities, the housing problem in big cities will cease to exist. I am against the idea of developing the underground. Because compared with building satellite cities, it is more costly. With each house to light even at daytime, we need a lot of electricity. Besides, it witt deprive people of the fresh air and bright sunshine which they can get so easily when they are above the ground.
