Read the passage carefully and choose the correct answer.
Species that belong to an area are said to be native species. Typically, they have been part of a given biological landscape for a long period, and they are well adapted to the local environment and to the presence of other native species in the same general habitat. Exotic species are interlopers, foreign elements introduced intentionally or accidentally into new settings through human activities. In one context an introduced species may cause no obvious problems and may, over time, be regarded as being just as "natural" as any native species in the same habitat. In another context, exotics may seriously disrupt delicate ecological balances and create a cascade of unintended consequences. The worst of these unintended consequences arise when introduced species put native species in destruction by preying on them, altering their habitats, or out-competing them in the struggle for food resources. Although biological introductions have affected environments the world over, the most destructive, effects have occurred on islands, where introduced insects, cats, pigs, rats, mongooses, and other nonnative species have caused the grave endangerment or outright extinction of literally hundreds of species during the past 500 years.
One of other reason to cause species extinction is overexploitation. This word refers to the utilization of a species at a rate that is likely to cause its extreme endangerment or outright extinction. Among many examples of severe overexploitation, the case of the great whales stands out in special relief. By the middle of the 20th century, unrestricted whaling had brought many species of whales to incredibly low population sizes. In response to public pressure, in 1982 a number of nations, including the USA, agreed to an international moratorium on whaling. As a direct result, some whale species which are thought to have been on extinction's doorstep 25 years ago have made amazing comebacks, such as grey whales in the western Pacific. Others remain at great risk. Many other species, however, continue to suffer high rates of exploitation because of the trade in animal parts. Currently, the demand for animal parts is centered in several parts of Asia where there. is a strong market for traditional medicines made from items like tiger bone and rhino horn.

Read the passage carefully and choose the correct answer.
By the year 2025, the Earth could lose as many as one fifth of all species known to exist today. In recent centuries, hundreds of species have disappeared, almost always as a result of human activities. The passenger pigeon, one familiar example, was a source of food until excessive hunting and habitat loss caused its extinction in 1914. The North American bison, whose populations were decimated by settlers and market hunters in the 1800s, came close to sharing the same fate. Bison survive today only because of the efforts of early conservationists.
Today, species require such efforts more urgently than ever. An essential task that falls to present-day conservationists is to determine which species are most, endangered, so that conservation resources' can be applied where action is needed most. Species are categorized by the degree to which their survival in the wild is threatened. World Wildlife Fund offers a sampling of animals and plants that fall mainly within the two most serious categories of- threat: critically endangered and endangered. What threatens these species' existence? Some of the top threats are habitat destruction by unsustainable logging and ever-encroaching human settlement; pollution of water, soil, and air by toxic chemicals; unnatural climate changes due to fossil fuel use; unmanaged fishing that exhausts fish stocks; and illegal hunting to supply the demand for skins, hides, traditional medicines, food, and tourist souvenirs. The list which conservationists presents only a fraction of the species at risk of extinction today and does not include thousands of species whose status we do not yet know. Hundreds of species without common names have been left out, which means that while many mammals are on this list, only a few insects and mollusks are included.
Species listed here range from the largest animal on Earth, the blue whale, to the majestic tiger, to the humble thick-shell pond snail. Large or small, beautiful or ugly, all species play a role in the complex circle of life. All of us depend on the natural resources of our planet. Each time a species is lost, the complexity, natural balance, and beauty of our world is diminished. And what threatens plants and animals ultimately threatens people as well.
36. According to the first paragraph _______.
a. species extinction is only caused by hunting
b. human beings protect wife life much more than they do harm to them
c. the main cause of species extinction is human activities
d. we can stop radically species extinction by 2025
37. The North American bison _______.
a. was completely extinct in 1800s
b. was not the aim of human hunting
c. was raised by settlers in 1800s
d. has escaped from extinction thanks to conservationists
38. Species are categorized _______.
a. to prevent hunting b. to provide food
c. to destroy their habitats d. to give preferential right to conserve
39. Which sentence is true?
a. Medicine is not a factor to cause species extinction.
b. The list which conservationists present does not include all kinds of species.
c. Pollution does nothing to species extinction.
d. Conservationists have good knowledge of all kinds of mollusks.
40. According to the last paragraph, _______.
a. species extinction has no relationship to human beings
b. what threaten plants and animals can do nothing to human beings
c. human beings depend on natural resources to survive
d. not every, species has a role in the circle of life.
