The advantages and disadvantages of a large population have long been a subject of discussion among economists. It has been argued that the supply of good land is limited. To feed a large population, poor land must be cultivated (耕种) and the good land worked intensively (精耕细作). Thus, each person produces less and this means a lower average income than could be obtained with a smaller population. Other economists have argued that a large population gives more chance of development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand.
One of the difficulties in carrying out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, the first concern of government will be to set a limit on the birthrate, whatever the final result may be. In a highly industrialized society the problem may be more complex. A decreasing birthrate may lead to unemployment because it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and building industry grows weaker. Faced with concerns such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.

孩子，我深深的同情你，现在我们考完试了我就没事做一下的，惊讶的发现，你们的阅读理解需要理解力能比我们大学的要强，虽然词汇很简单，呵呵，加油学英语哦
7。A
Thus, each person （of a LARGE population) produces less and this means a lower average income than (LARGE compared to SMALLER) could be obtained with a smaller population.
<large has "lower average income", so smaller population must have higher income ^^
8. B
"In the developing country" ... "pressing hard upon the limits of food, space and natural resources" ... "to set a limit on the birthrate"
9. B
"In a highly industrialized society" ... "A decreasing birthrate may lead to unemployment" ... "the government of a developed country " ...
10. B
^^ hope this is helpful to you =D
第一段讲经济学家对人口众多的优缺点的不同看法；第二段讲不同国家对人口增长的不同看法，可见本文的主题是人口增长。
7A
①根据常理，人口少则总产量少选 “lower production”,
②原文中"……this means a lower average income than could be obtained with a smaller population."
人口多意味着与人口少时相比更低的平均收入。亦即人口少导致更高的平均收入。 选“a higher average income”
8B
原文中”In the developing country ……… the first concern of government will be to set a limit on the birthrate“ 故选发展中国家
9B
选项中的”grow down" 对应原文中的“decreasing” 人口增长率下降
