Question

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 from 44 to 50.

For many people who live in cities, parks are an important part of the landscape. They provide a place for people to relax and play sports, as well as a refuge from the often harsh environment of a city. What people often overlook is that parks also provide considerable environmental benefits.

One benefit of parks is that plants absorb carbon dioxide—a key pollutant—and emit oxygen, which humans need to breathe. According to one study, an acre of trees can absorb the same amount of carbon dioxide that a typical car emits in 11,000 miles of driving. Parks also make cities cooler. Scientists have long noted what is called the Urban Heat Island Effect: building materials such as metal, concrete, and asphalt absorb much more of the sun’s heat and release it much more quickly than organic surfaces like trees and grass. Because city landscapes contain so much of these building materials, cities are usually warmer than surrounding rural areas. Parks and other green spaces help to mitigate the Urban Heat Island Effect.

Unfortunately, many cities cannot easily create more parks because most land is already being used for buildings, roads, parking lots, and other essential parts of the urban environment. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are very complex and require complicated engineering, but others are simple container gardens that anyone can create with the investment of a few hundred dollars and a few hours of work.

Rooftop gardens provide many of the same benefits as other urban park and garden spaces, but without taking up the much-needed land. Like parks, rooftop gardens help to replace carbon dioxide in the air with nourishing oxygen. They also help to lessen the Urban Heat Island Effect, which can save people money. In the summer, rooftop gardens prevent buildings from absorbing heat from the sun, which can significantly reduce cooling bills. In the winter, gardens help hold in the heat that materials like brick and concrete radiate so quickly, leading to savings on heating bills. Rooftop vegetable and herb gardens can also provide fresh food for city dwellers, saving them money and making their diets healthier. Rooftop gardens are not only something everyone can enjoy, they are also a smart environmental investment

Using the information in paragraph 2 as a guide, it can be inferred that ______________

A. most people prefer parks to rooftop gardens

B. most people prefer life in the country over life in the city

C. cities with rooftop gardens are cooler than those without rooftop gardens

D. some plants are not suitable for growth in rooftop gardens 

Answer 1

Đáp án C

Thông tin: Parks also make cities cooler. Scientists have long noted what is called the Urban Heat Island Effect: building materials such as metal, concrete, and asphalt absorb much more of the sun’s heat and release it much more quickly than organic surfaces like trees and grass. Because city landscapes contain so much of these building materials, cities are usually warmer than surrounding rural areas. Parks and other green spaces help to mitigate the Urban Heat Island Effect.

Dịch nghĩa: Công viên cũng làm cho các thành phố mát hơn. Các nhà khoa học từ lâu đã ghi nhận những gì được gọi là Hiệu ứng đô thị đảo nhiệt: vật liệu xây dựng như kim loại, bê tông và nhựa đường hấp thụ nhiều nhiệt của mặt trời và phát tán nó nhanh hơn nhiều so với bề mặt hữu cơ như cây cối và cỏ. Bởi vì phong cảnh thành phố chứa rất nhiều các vật liệu xây dựng, thành phố thường ấm hơn so với khu vực nông thôn xung quanh. Công viên và không gian xanh khác sẽ giúp giảm thiểu Hiệu ứng đô thị đảo nhiệt.

Như vậy có thể suy ra rằng thành phố có nhiều cây xanh sẽ mát hơn là khi không có cây xanh.

Phương án C. cities with rooftop gardens are cooler than those without rooftop gardens = những thành phố với những khu vườn trên mái nhà mát hơn những thành phố không có vườn trên mái nhà, là phương án chính xác nhất.

          A. most people prefer parks to rooftop gardens = hầu hết mọi người thích công viên hơn các khu vườn trên mái nhà.

          B. most people prefer life in the country over life in the city = hầu hết mọi người thích cuộc sống ở nông thôn hơn cuộc sống trong thành phố

          D. some plants are not suitable for growth in rooftop gardens = một số loài cây không phù hợp để trồng trong các khu vườn trên mái nhà.
