听力原文: The old house-allotting policy had at least two disadvantages. First, the government spent a lot of money building some houses, but these houses were allotted to people free of charge. Thus. the government would have no money to build more houses for people who badly needed them. Second, the persons who were in power could get more houses than those who were powerless. This was quite unfair. On the contrary, the new system of house allotment may bring about many new things. For example, the government will have more money which can be used in house construction. So, the housing industry can develop more quickly. Besides, because houses will be sold to people, the chances they get will be equal.
