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.
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.
It can be inferred from the passage that the author would most likely endorse a program that ______.
A. permitted the construction of buildings in city park land provided they have rooftop gardens.
B. extended discounts on plants to customers who use them to create rooftop gardens.
C. offered free admission to schools willing to take their students on field trips to the city park.
D. promised vacation getaways to cooler destinations for those trapped in the city at the peak of summer.
Đáp án B
Có thể được suy ra từ đoạn văn rằng tác giả có thể sẽ ủng hộ 1 chương trình ______.
A. cho phép thi công các tòa nhà trên đất công viên thành phố nếu chúng có khu vườn thượng.
B. chiết khấu giá cho các loại cây được khách hàng sử dụng để tạo ra các khu vườn thượng.
C. cung cấp vé vào miễn phí cho các trường học đưa học sinh đi thực địa tới các công viên trong thành phố.
D. hứa hẹn các kì nghỉ tới những điểm đến mát mẻ hơn cho những người mắc kẹt trong thành phố trong thời kì đỉnh điểm của mùa hè.
Có thể được suy ra từ ý tứ trong bài, tác giả đã chỉ ra nhiều lợi ích của vườn thượng thậm chí còn ưu việt hơn cả công viên, thí dụ như:
+: “However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens” – (Tuy nhiên , các thành phố vẫn có thể hưởng lợi từ nhiều ảnh hưởng tích cực của công viên bằng việc khuyến khích người dân kiến tạo nên những hình thái khác của không gian xanh đó là: khu vườn thượng)
+“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” – (Vào mùa hè, những khu vườn thượng ngăn cản các tòa nhà khỏi việc hấp thụ nhiệt từ mặt trời, điều đó có thể là giảm đáng kể hóa đơn làm mát. Vào mùa đông, vườn thượng giúp giữ nhiệt mà những chất liệu như gạch và xi măng làm tỏa ra nhanh chóng, dẫn tới tiết kiệm được chi phí sưởi ấm. Vườn thượng trồng rau xanh đồng thời có thể cung cấp được thực phẩm sạch cho người dân thành phố, tiết kiệm tiền và làm cho bữa ăn thêm lành mạnh).
=> Đáp án B là hợp lí nhất.
