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.

Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.

Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.

However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments.

Mọi người ơi giúp em với ạ ! em cảm ơn mọi người nhiều lắm ạ 
 

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.

Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tiger, for instance, which once roamed the jungles in vast number, now only about 2,300 and by the year 2025, their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part of what is causing the problem of extinction. Animals like Bengal tigers as well as other endangered species are a valuable part of the world’s ecosystem. International laws protecting these animals must be enacted to ensure their survival and the survival of our planet.

Countries around the world have begun to deal with the problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks and they often must also depend on world organizations for support. With the money they get, they can invest in equipment, and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective but it will not, by itself, prevent animals from being hunted and killed.

 

Question 24. What is the main topic of the passage?

A. the Bengal tiger                              B. international boycotts

C. endangered species                                    D. problems with industrialization

Question 25. Which of the following is closest in meaning to the word “alarming” in paragraph 1?

A. dangerous                           B. serious                                C. gripping                  D. distressing

Question 26. Why does the Bengal tiger become extinct?

A. Because the number of them is so small.

B. Because hunters want their valuable body parts.

C. Because hunters satisfy their personal gratification themselves.

D. All are correct

Question 27.  What does the word “their” refer to in paragraph 1?

A. international laws               B. these animals                      C. survival                   D. planet

Question 28. Which of the following best describes the author’s attitude?

A. forgiving                            B. concerned                           C. vindictive               D. surprised
