Đọc và trả lời các câu hỏi từ câu 31 đến câu 35 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.
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
Trang 4Câu 31: According to the first paragraph .
A species extinction is caused by nature
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
Câu 32: 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
Câu 33: The word “decimated” in paragraph 1 is closest in meaning to .
Câu 34: 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
Câu 35: 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
D not every species has a role in the circle of life
