Cities around the world are getting hotter, and it's not just because of global climate change. A phenomenon known as the 'urban heat island' effect is a major contributor. This occurs when cities replace natural land cover with dense concentrations of pavement, buildings, and other surfaces that absorb and retain heat. This effect can cause city centers to be several degrees warmer than surrounding rural areas, especially at night.
This extra heat is not just uncomfortable; it has serious consequences. It increases energy demand for cooling, which can strain power grids during heat waves. It also worsens air pollution by accelerating the formation of harmful ground-level ozone. For public health, extreme heat can be dangerous, leading to heatstroke and other heat-related illnesses, particularly for vulnerable populations like the elderly and children.
To combat the urban heat island effect, cities are exploring various strategies. These include painting roofs with reflective white paint, planting more trees and creating green roofs, and using more permeable pavement that allows water to evaporate and cool the air. These measures can help make cities more livable and sustainable for the future.
Question 25. What is the main topic of the passage?

This shift has both advantages and disadvantages. On the one hand, digital texts are convenient, portable, and often cheaper than printed versions. They also offer features like adjustable font sizes and built-in dictionaries, which can be very helpful. On the other hand, some studies suggest that reading on a screen can lead to digital eye strain and may make it harder for us to concentrate and remember information deeply. Many people also miss the physical experience of holding a book and turning its pages. Despite the rise of digital media, printed books have not disappeared. In fact, many readers enjoy both formats, choosing the one that best suits their needs at a particular moment.

The materials used in cities are a key part of the problem. Dark-colored asphalt roads and rooftops absorb a high percentage of solar energy and radiate it back into the atmosphere, warming the air. Additionally, cities have fewer trees and green spaces, which would normally help to cool the environment through shade and evapotranspiration (the process by which plants release water vapor). Waste heat from vehicles, air conditioners, and industrial processes also exacerbates the problem.
