Read the passage carefully and choose the correct answer.

We live in a dynamic world, and habitats are always undergoing changes at all sorts of levels. However, natural changes usually occur at a slow pace so that impacts on individual species tend to be slight - at least in the short term. When the pace of change is greatly accelerated, there may be no time for individual species to react to new circumstances, and the effects can be disastrous. Briefly, this is the reason that rapid habitat loss is regarded as the chief cause of species endangerment, and there is no force more powerful in this regard than human beings. To some extent, every part of the earth has been affected by human activities, especially during this past century. This applies on virtually every scale, from the loss of microbes in soils that once supported tropical forests, to the extinction of fish and other aquatic species in polluted freshwater habitats, to changes in global climate caused by the release of greenhouse gases.

From the perspective of an individual human lifetime, such changes may be hard to detect and their effects on individual species may be hard to predict. But the lesson is clear enough. For example, although many countries have had plans to grow many tropical forests, they are highly susceptible to destruction because the soils in which they grow are poor in available nutrients. Centuries may be required to bring back a forest that was cut down or burnt out in the space of a few years. Many of the world's severely threatened animals and plants live in such forests, and it is certain that huge numbers of them will disappear if present rates of forest loss continue.

36. Habitats in the world are unchangeable and fixedly exist.

a. True

b. False

c. No information

37. All species can adapt themselves to new circumstances easily and quickly.

a. True

b. False

c. No information

38. Human beings are the main cause that leads to rapid habitat loss.

a. True

b. False

c. No information

39. Many kinds of fish are also in danger of extinction because water habitats are polluted.

a. True

b. False

c. No information

40. Many countries have grown as many tropical forests as they destroyed in the past years.

a. True

b. False

c. No information

Fill in each numbered blank with one suitable word or phrase.

Limited distributions are often a consequence of other threats: populations confined to one or a few small areas because of habitat (47) _____, for example, may be disastrously affected by random factors. Diseases can have severe (48) _____ on species lacking natural genetic protections against particular pathogens, like the rabies and canine distemper viruses that are currently devastating carnivore populations in East Africa. Domestic animals are usually the reservoirs of these and other diseases affecting wild (49) _____, showing once again that human activities lie at the root of most causes of endangerment.
