===TITLE=== UNIT 10: READING COMPREHENSION :: 12 QUESTIONS ===TIMER=== 20 ===PART=== 1. READING :: 12 :: 1 ===SECTION=== Passage 1 Mother Earth, which has sustained humans for thousands of years, is currently facing the severe effects of climate change. Global warming, which is driven by heavy pollution, is causing temperatures to rise rapidly around the globe. The polar region, which is covered in thick layers of ice, is experiencing massive melting. This phenomenon threatens the ecological balance and leads to significant habitat loss for animals like polar bears. In addition, the ocean, which is the largest water body on the planet, absorbs a lot of this excess heat. This causes sea levels to rise, directly endangering the gorgeous coastlines of many continents. A well-known scientist, who leads our local science club, believes that fresh water resources are also shrinking. He tries to persuade people to appreciate the natural environment and adjust their daily habits. For instance, he encourages farmers to stop using harmful pesticides, which poison the soil and rivers. Furthermore, the destruction of the bamboo forest, which is crucial for endangered species like pandas, must be halted. Everyone must make a contribution to save our planet from being completely polluted. Only by maintaining the delicate flora and fauna can we ensure that future generations will enjoy the giant, beautiful landscapes we have today. ===MCQ=== 1. What is the primary cause of rising temperatures according to the passage? *A. Heavy pollution driving global warming. B. Moonquakes happening in outer space. C. The expansion of the bamboo forest. D. Zebras migrating to the polar region. Giải thích: Đoạn 1 ghi: “Global warming, which is driven by heavy pollution, is causing temperatures to rise rapidly…” ===MCQ=== 2. Which area is explicitly described as experiencing massive melting? A. The grassland. *B. The polar region. C. The Mediterranean Sea. D. Venus. Giải thích: Đoạn 1 ghi: “The polar region, which is covered in thick layers of ice, is experiencing massive melting.” ===MCQ=== 3. How does the ocean react to global warming in the text? A. It completely freezes over in winter. B. It produces more fresh water. *C. It absorbs a large amount of excess heat. D. It decreases the global sea levels. Giải thích: Đoạn 1 ghi: “…the ocean… absorbs a lot of this excess heat.” ===MCQ=== 4. What does the scientist in the local science club try to do? A. Destroy the coastline. B. Launch a new rocket. C. Raise livestock in the ocean. *D. Persuade people to value nature and change their habits. Giải thích: Đoạn 2 ghi: “He tries to persuade people to appreciate the natural environment and adjust their daily habits.” ===MCQ=== 5. Why are harmful pesticides mentioned as a problem? *A. They poison the earth and waterways. B. They cause massive earthquakes and moonquakes. C. They increase the size of the continents. D. They are absolutely essential for the ecological balance. Giải thích: Đoạn 2 ghi: “…harmful pesticides, which poison the soil and rivers.” ===MCQ=== 6. What is the ultimate goal of making a contribution to save the planet? A. To build more water bodies on Mercury. *B. To preserve the flora, fauna, and giant landscapes for the future. C. To cut down all the old trees. D. To study the geology of the solar system. Giải thích: Cuối đoạn 2 ghi: “Only by maintaining the delicate flora and fauna can we ensure that future generations will enjoy the giant, beautiful landscapes we have today.” ===SECTION=== Passage 2 Geology, which focuses on the physical structure and substance of the Earth, helps us understand various landforms. For example, a continent, which is a massive continuous expanse of land, hosts extremely diverse ecosystems. A nature reserve, which is typically set aside by the government to protect flora and fauna, plays an essential role in preserving endangered species. In Africa, the vast grassland, which is home to the zebra and the long-necked giraffe, relies heavily on the natural food chain. Unfortunately, these animals are highly threatened by human expansion. In North America, the beaver, which builds dams across rivers, creates new wetland habitats for other species. However, if humans cut down too many trees, these creatures face severe habitat loss. The Mediterranean Sea, which is a famous and best-known water body, also struggles with polluted waters affecting its marine life. Scientists continuously launch campaigns to save from extinction the species that are most vulnerable. They adjust conservation strategies to maintain the ecological balance. Understanding the significance of every liquid drop of fresh water and every piece of land is crucial. We must stop destroying the surface of Mother Earth and start protecting our livestock, wild animals, and native plants. ===MCQ=== 7. What does geology primarily help us understand? A. How to build fast rockets for outer space. B. The atmospheres of Venus and Mercury. *C. The physical structure and landforms of the Earth. D. The exact number of humans living on the planet. Giải thích: Đoạn 1 ghi: “Geology, which focuses on the physical structure and substance of the Earth, helps us understand various landforms.” ===MCQ=== 8. What role does a nature reserve play according to the text? A. It produces harmful chemical pesticides. B. It cuts down trees for commercial wood. C. It pollutes the natural environment. *D. It protects endangered species and the local flora and fauna. Giải thích: Đoạn 1 ghi: “A nature reserve, which is typically set aside by the government to protect flora and fauna, plays an essential role in preserving endangered species.” ===MCQ=== 9. Which animals are explicitly mentioned as living in the African grassland? *A. The zebra and the giraffe. B. The beaver and the panda. C. Livestock and polar bears. D. Fish and birds. Giải thích: Đoạn 1 ghi: “In Africa, the vast grassland, which is home to the zebra and the long-necked giraffe…” ===MCQ=== 10. How do beavers contribute to the natural environment in North America? A. They drink all the liquid in the rivers. *B. They construct dams that create new wetland habitats. C. They cause severe global warming. D. They launch major campaigns to save animals. Giải thích: Đoạn 2 ghi: “…the beaver, which builds dams across rivers, creates new wetland habitats for other species.” ===MCQ=== 11. What is a major environmental issue facing the Mediterranean Sea? A. It is drying up into a massive desert. B. It is overrun by giant wild giraffes. *C. It is dealing with contaminated waters that affect marine life. D. It is experiencing frequent and dangerous moonquakes. Giải thích: Đoạn 2 ghi: “The Mediterranean Sea… also struggles with polluted waters affecting its marine life.” (polluted = contaminated). ===MCQ=== 12. What is considered crucial at the end of the passage? A. Moving to a different planet in the solar system. B. Increasing the amount of livestock globally. C. Using more pesticides to grow food rapidly. *D. Realizing the importance of fresh water and land to protect the Earth. Giải thích: Cuối đoạn 2 ghi: “Understanding the significance of every liquid drop of fresh water and every piece of land is crucial. We must stop destroying the surface of Mother Earth…”
