XX年12月大学英语六级复习题
Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Questions 21 to 25 are based on the following passage:
There are two methods of fighting, the one by law, the other by force; the first method is that of men, the second of beasts; but as the first method is often insufficient, one must have recourse to the second. It is, therefore, necessary for a prince to know well how to use both the beast and the man. This was covertly taught to rulers by ancient writers, who related how Achilles and many others
of those ancient princes were given to Chiron the centaur
to be brought up and educated under his discipline. The parable of this semi animal, semi human teacher is meant to indicate that a prince must know how to use both natures, and that the one without the other is not durable. A prince, being thus obliged to know well how to act as a beast, must imitate the fox, and the lion, for the lion cannot protect himself from traps, and the fox annot defend himself from wolves. Those that wish to be only lions do not understand this. Therefore, a prudent ruler ought not to keep faith
when by doing so it would be against his interest, and when the reasons which made him bind himself no longer exist. If men were all good, this precept would not be good ; but as they are bad, and would not observe their faith with you, so you are not bound to keep faith with them. Nor have legitimate grounds ever failed a prince who wished to show colorable excuse for the nonfulfilment of his promise. Of this one could furnish an infinite number of examples, and show how many times peace has been broken, and how many promises rendered worthless, by the faithlessness of princes, and those that have best been able to imitate the fox have sueeded best. But it is necessary to be able to disguise this character well, and to be a great feigner and dissembler, and men are so simple and so ready to obey present necessities, that the one who deceives will always find those who allow themselves to be deceived.

Questions 26 to 30 are based on the following passage: The forest from which Man takes his timber is the
tallest and most impressive plant munity on Earth. In terms of Man's brief life it appears permanent and unchanging, save for the seasonal growth and fall of the leaves, but to forester it represents the climax of a long suession of events. No wooded landscape we see today has been forest
for all time. Plants have minimum requirements of temperature and moisture and, in ages past, virtually every part of Earth's surface has at some time been either too dry or too cold for plants to survive. However, as soon as climatic conditions change in favour of plant life, a
fascinating sequence of changes ours, called a primary suession.
First to colonize the barren land are the lowly lichens, surviving on bare rock.
Slowly, the acids produced by these organisms crack the rock surface, plant debris aumulates, and mosses establish
a shallow root?hold. Ferns may follow and, with short grasses and shrubs, gradually form a covering of plant life. Roots probe even deeper into the developing soil and eventually large shrubs give way to the first trees. These grow rapidly, cutting off sunlight from the smaller plants, and soon establish plete domination—closing their ranks
and forming a climax munity which may endure for thousands
of years.
Yet even this munity is not everlasting. Fire may destroy it outright and settlers may cut it down to gain land for pasture or cultivation. If the land is then abandoned, a secondary suession will take over, developing much faster on the more hospitable soil. Shrubs and trees are among the early invaders, their seeds carried by the wind, by birds and lodged in the coats of mammals.For as long as it stands and thrives, the forest is a vast machine, storing energy and many elements essential for life.

D) The introduction of new type of plants.
28.In a “primary suession', what makes it possible for mosses to take root?
A) The type of rock.
B) The amount of sunlight.
C) The amount of moisture.
D) The effect of lichens.
29.What conditions are needed for shrubs to bee established?
A) Ferns must take root.
B) The ground must be covered with grass.
C) More soil must aumulate.
D) Smaller plants must die out.
30.Why is a “secondary suession” quicker?
