In this article, we will provide a detailed IELTS Reading practice test on the topic “How Does Urban Sprawl Affect Local Ecosystems?” We will also offer in-depth answers, vocabulary explanations, and grammatical analyses to help you prepare effectively for the IELTS Reading test.

Reading Passage

Urban Sprawl and Local Ecosystems

Urban sprawl refers to the uncontrolled expansion of urban areas into the surrounding countryside. This phenomenon is driven by increasing populations and the desire for suburban living. While it provides benefits such as more housing and better living conditions for some, it has significant environmental repercussions.

One of the primary effects of urban sprawl is habitat destruction. As cities expand, natural habitats are cleared to make way for new housing, roads, and commercial areas. This results in the loss of biodiversity, as plants and animals lose their natural homes. Many species become endangered or extinct due to the destruction of their habitats.

Urban Sprawl Habitat Destruction

Pollution is another critical consequence. Increased construction and vehicular traffic lead to higher levels of air, water, and soil pollution. Chemical runoff from new developments contaminates local water bodies, affecting aquatic life and making water unsafe for human consumption. Additionally, the heat island effect, where urban areas become significantly warmer than their rural surroundings, further exacerbates environmental stress on local ecosystems.

Urban sprawl also disrupts natural water cycles. Impermeable surfaces like roads and pavements reduce the infiltration of rainwater into the soil, leading to increased surface runoff and the risk of flooding. This disrupts local watersheds and can lead to severe erosion and sedimentation in rivers and streams.

Furthermore, urban sprawl contributes to climate change. The increased need for transportation and energy consumption in sprawling urban areas results in higher greenhouse gas emissions. These emissions contribute to global warming, which has far-reaching impacts on both local and global ecosystems.

In conclusion, while urban sprawl may provide certain socio-economic benefits, its impact on local ecosystems is predominantly negative. The loss of natural habitats, increased pollution, disruption of natural water cycles, and contribution to climate change are significant issues that need to be managed carefully to ensure sustainable development.

Common Mistakes

1. Misinterpreting the Details: It’s essential to carefully read the passage to distinguish between facts and opinions.
2. Vocabulary Trap: Sometimes, similar-sounding words can confuse test-takers. For instance, understanding the difference between ‘reduce’ and ‘increase’ in context is crucial.
3. Generalizing Statements: Avoid assuming that one aspect of the topic covers all areas. Urban sprawl affects various environmental aspects differently.

Vocabulary

• Urban Sprawl (n): /ˈɜːrbən sprɔːl/ – The uncontrolled expansion of urban areas.
• Biodiversity (n): /ˌbaɪəʊdaɪˈvɜːrsəti/ – The variety of plant and animal life in a particular habitat.
• Pollution (n): /pəˈluːʃn/ – The presence or introduction of harmful substances into the environment.
• Heat Island Effect (n): /hiːt ˈaɪlənd ɪˈfɛkt/ – Urban areas becoming significantly warmer than rural areas.
• Erosion (n): /ɪˈrəʊʒn/ – The process of eroding or being eroded by wind, water, or other natural agents.

Grammar

Passive Voice

The passage utilizes a lot of passive voice to emphasize the effect of actions rather than who is performing the actions.

• Form: [Object] + [form of “to be”] + [past participle of main verb]
• Example from the passage: “Many species become endangered or extinct due to the destruction of their habitats.”
