Passage Two
Questions 26 to 30 are based on the following passage.
As supplier of most of the food we eat and of raw materials for many industrial
processes, agriculture is clearly an important area of the economy. But the industrial
performance of agriculture (the relative efficiency of agricultural production compared to
other areas in the economy) is even more important than this. For in nations where the
productivity of farmers is low, most of the working population is needed to raise food
and few people are available for the production of investment goods or for other
activities required for economic growth. Indeed, one of the factors related most closely
to the per capita income (人均收入) of a nation is the fraction of its population engaged
in farming. In the poorest nations of the world more than half of the population lives on
farms. This compares sharply with less than 10 percent in western Europe and less than 4
percent in the United States.
In short, the course of economic development in general depends in a fundamental
way on the performance of farmers. This performance, in turn, depends on how
agriculture is organized and on the economic environment, or market structure, within
which it functions. In the following pages the performance of American agriculture is
examined. It is appropriate to begin with a consideration of its market structure.

Passage Three
Questions 31 to 35 are based on the following passage:
Editor:
While a new school term is about to begin, perhaps we should reconsider the matter
of examinations. In July, two writers (Letters to the Editor) praised the cancellation of
exams because they believe “tests don’t tell the whole story.”
As a teacher who has worked in four countries, I have had the experience that a
student who earns good marks is generally a good student, and that a student’s final
mark in a subject is usually a grade average of the year’s work. Of course there are
exceptions, but they do not have the frequency that would give an unfair picture of a
student’s ability.
The simple fact is that proper class work, diligent exam studies and good marks are
almost certain indicators of a student’s future performance. The opposite is, almost
certainly, incompetence.
There is no acceptable substitute for competition and examination of quality. How
can teachers and future officials determine what a student has learned and remembered?
