Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions
Coincident with concerns about the accelerating loss of species and habitats has been growing appreciation of the importance of biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated with tropical rain-forest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life.
An alien exploring Earth would probably give priority to the planet’s dominants, most-distinctive feature - the ocean. Humans have a bias toward land that sometimes gets in the way of truly examining global issues. Seen from far away, it is easy to realize that landmasses occupy only one-third of the Earth’s surface. Given that two thirds of the Earth’s surface is water and that marine life lives at all levels of the ocean, the total three-dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species.
The fact that half of the known species are thought to inhabit the world’s rain forests does not seem surprising, considering the huge number of insects that comprise the bulk of the species. One scientist found many different species of ants in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750,000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably the sea. Nearly every major type of plant and animal has some representation there .To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water contains life, on the order of 100 to 100,000 bacterial cells plus assorted microscopic plants and animals, including larvae of organisms ranging from sponges and corals to starfish and clams and much more.

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 season growth and fall of the leaves, but to the 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 cool for plants to survive.
However, as soon as climatic conditions change in favor of plant life, a fascinating sequence of changes, called a primary succession, occurs first to colonize the barren land and the lichen surviving on bare rock. Slowly, the acids produced by these organisms crack the rock’s surface, plants debris accumulate and mosses establish shallow root-holes. Ferns may allow and, with short grasses and shrubs, gradually form a covering of plant life. Roots broke 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 cultivations. 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 coat of mammals.
For as long as it stands and strives, the forest is a vast machine storing energy and the many elements essential for life.
Why do we tend to think the forest as permanent?
A. Because it is renewed each season.
B. Because it is an essential part of our life.
C. Because our lives are comparatively short.
D. Because the trees are so tall.
Đáp án là C.
permanent : vĩnh cửu. C. Because our lives are comparatively short. (Bởi vì cuộc sống của chúng tôi là tương đối ngắn.)
