英语四级仔细阅读练习题(3)
The future population will be older than today, and this in turn will
change the patterns of social demands. However, Mexico will still be far from
the "aging societies" that will most likely prevail (占优势 ) in the industrialized
countries. In less than 25 years, the country will have to add almost as much
infrastructure as it has already built up to now, simply to maintain services
and production at the current levels. This will be a tremendous challenge,
although a similar one was faced successfully in the recent past, when available
infrastructure was doubled in two decades or so. It is no wonder that much has
been said about the need to reduce or preferably halt Mexico's population
control which is taken for granted as both good and necessary. It has also
gained supporters in the developing world, and Mexico is no exception. But the
arguments about population are complicated, as the following discussion
illustrates.
Even if Mexico's population reaches 125 million by the year 2010, its
population density is still smaller than the 1985 population density of some 50
countries. By international standards Mexico will still not be overpopulated by
the year 2010. If wealth is generated by people, the more individuals there are,
the greater the wealth that potentially could be generated. Why should Mexico
control its population at density levels below those of the richer countries if
more population represents the possibility of generating more wealth?
On the other hand, it is often pointed out that once sustainability(支撑力)
limits are near or are reached, there are decreasing productivity gains
(or,perhaps more accurately, increasing productive losses) , and people become a
cost rather than an asset. If we assume that there are sustainability limits and
that we are close to reaching these limits at a world level, then it is
appropriate to check population growth.
21. According to the passage, the population argument is focused
on_______.
A. whether more people are a property or a cost
B. whether Mexico should control its population growth or not
C. whether the density of population in Mexico is large or small
D. what the standard international sustainability limit is
22. Which of the following is TRUE according to the first paragraph?
A. Mexico has stepped into an aging society.
B. It is not necessary for Mexico to control its population.
C. Mexico population is younger than that of developed countries.
D. It is not necessary for Mexico to develop its infrastructure.
23. By "infrastructure"(Para. 2) the author means_______.
A. buildings
B. the basic framework of a country, such as schools, services, etc.
C. social demands
D. services and production
24. It may be inferred from the 3rd paragraph that_______.
A. it isn't necessary for Mexico to control its population growth
B. population is likely to grow at a slower pace than in the past
C. the more people there are, the greater the wealth people could
generate
D. Mexico should control its population growth because she belongs to the
developing countries
25. To check population growth is necessary when_______.
A. there are decreasing productivity gains
B. there are increasing productivity losses
C. we are close to reaching the sustainability limits at a world level
D. people become a cost
