🎯 Lesson Goal
The goal is to understand how passive voice with modals is used to talk about possibilities, obligations, and recommendations related to sustainable city projects. You will learn to identify and use modal passive forms in realistic urban planning situations.
🧠 Grammar Focus
Passive voice with modals is used when we want to focus on actions done to something or someone and express ability, possibility, necessity, or advice. It is common in formal and professional contexts to describe rules, obligations, or possibilities without mentioning the doer. The structure usually is modal + be + past participle. For example, ‘The waste must be recycled,’ or ‘Public parks should be maintained regularly.’ Modal passive forms appear with modals like can, must, should, might, and may. Typical situations include rules for environmental protection, suggestions for city improvements, and assumptions about completed actions. This form helps express ideas politely or formally and focuses on the action rather than the person who performs it.
📖 Short Reading
In many cities, green spaces must be protected to improve air quality. New buildings should be designed with energy efficiency in mind. Waste recycling can be encouraged through public policies. It is said that urban transport might be improved by more bike lanes and electric buses. Noise pollution must be reduced in residential areas. Many sustainable projects have to be supported by local governments. Sometimes, community gardens should be created in unused spaces. Air pollution can be measured by sensors placed in different parts of a city. Energy-saving technologies must be installed in new offices. Rules about water conservation should be followed strictly. Walking paths can be built around parks. These measures might be adopted worldwide to create better cities. Overall, actions like these need to be taken seriously to protect our environment.
