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 community 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 succession 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 occurs, called a primary succession.

       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 accumulates, 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 complete domination—closing their ranks and forming a climax community which may endure for thousands of years.

Yet even this community 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 succession 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.

26.What does the forest strike mankind as permanent?

A) The trees are in community.

B) The forest is renewed each season.

C) Man's life is short in comparison.

D) It is an essential part our lives.

27.What has sometimes caused plants to die out of the past?

A) Interference from foresters.

B) Variations in climate.

C) The absence of wooded land.

D) The introduction of new type of plants.

28.In a “primary succession', 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 become established?

A) Ferns must take root.

B) The ground must be covered with grass.

C) More soil must accumulate.

D) Smaller plants must die out.

30.Why is a “secondary succession” quicker?

A) The ground is more suitable.

B) There is more space for new plants.

B) Birds and animals bring new seeds.

D) It is supported by the forest.

【參考答案】

短文大意：本文主要敘述人與自然的生態關係，地球上的森林是經過千百萬年演變而存活下來的人類生態環境。那些我們今天所看到的光禿禿的大地過去曾是茂密的 森林。植物的生長與氣候密切相關，一旦氣候變得惡劣，植物便會滅絕。如果人類一味地亂砍亂伐，墾田開荒，那麼地球上的生態環境就會遭到破壞，生物鏈就要發生改變。

26. 答 案C。【參考譯文】森林對人類的衝擊在什麼方面是永久性的 ?【試題分析】本題爲一般理解題，需要在字裏行間找答 案。【詳細解答】在這篇文章的第一段的第二句話，可以找到 C)是正確答 案。

27. 答 案B。【參考譯文】有時候是什麼造成從前的植物滅絕 ?【試題分析】本題考察對上下文的理解，需從字裏行間找答 案。

【解答要領】第二段中，作者提到了氣候是植物生長的基本條件，而氣候一旦變得惡劣，植物可能會滅絕。

28. 答 案D。【參考譯文】在“初級演”中，什麼使苔蘚生根成爲可能 ?【試題分析】本題爲一般閱讀理解題，需從段落的字裏行間中找答案。【詳細解答】第三段的第二句話中，作者提到了首先能在岩石上生存的植物是 lichen(地衣)，然後在地衣生長之後，由於地衣的影響才能使moss(苔蘚))的生長成爲可能。

29. 答 案C。【參考譯文】灌木穩固生長需要什麼條件 ?【試題分析】同上。

【解答要領】在第三段的中間，只有在長過苔蘚之後草木和 shrub(灌木)才能生長，因爲已經固定相當一部分土壤，有利於植物生長，故選C)。

30. 答 案A。【參考譯文】爲什麼“第二次演替”較快 ?【試題分析】同上。【詳細解答】從第四段的中間，我們可以看出，根本的原因乃是土壤較爲適宜。
