阅读理解 同题异文　群文阅读 Building the future Unit 2 A (选自外研版选择性必修第三册Unit 5) Nature in Architecture Trees，plants and flowers are all around us and we enjoy their beauty every day.In fact，we are so used to them that we may even take them for granted without realising how much inspiration they have given us.When we look at a pine cone, we might think how much it looks like the tiles on a roof.An open flower might make us think how closely it resembles an umbrella.It is natural to think in this way，but of course it wasn’t the umbrella that inspired the flower or the roof that inspired the pine cone. Nature has inspired many of the most fascinating designs around us，including those in architecture.From Barcelona’s forest-like Sagrada Familia to the modern style of Beijing’s Water Cube，nature is presented in various architectural designs.Today，architects continue to explore ways to capture the beauty of natural forms，to mimic the way nature works or even to make natural organisms part of a building. ArtScience Museum，Singapore People whose interest is exploring the relationship between art and science will enjoy Singapore’s ArtScience Museum.The building was designed to show the connection between nature and the modern city environment in which it sits.Shaped to resemble a lotus flower，it appears to float above the waterfront promenade and the water that surrounds it.Its roof collects rainwater and channels it 35 metres down to a waterfall in the centre of the space.The water is then recycled through the building’s plumbing system.Visitors are often amazed to find themselves in an urban building that so truly captures the beauty of natural forms. The Eastgate Centre，Harare Harare’s Eastgate Centre is a superb example of biomimicry.To use biomimicry is to create structures based on natural forms and processes.Zimbabwean architect Mick Pearce was inspired to create the Centre while watching a nature documentary in which termites were constructing their nests.The insects built mounds covered in little holes designed to allow air to move freely in and out of the mounds.In a similar way，the Eastgate Centre has a “skin” covered in holes.During the day， warm air is drawn into the building through the holes，cooling as it reaches the middle of the building.At night，the heat absorbed by the wall during the day warms the cool air，creating a comfortable temperature inside.The design reduces the need for traditional air conditioning and heating systems，so the building uses less energy and costs less to run. The Algae House，Hamburg The world’s first algae-powered building is in Hamburg，Germany.The surface of the apartment building is covered in panels that contain algae.The algae are fed with liquid nutrients and carbon dioxide to encourage them to grow.In bright sunshine，they grow faster and provide shade.The panels also capture heat from the sun and convert it into energy that powers the building.And that’s not all—the algae inside the panels can be harvested and used to produce fuel.The building therefore not only responds to its environment and uses less energy，but also reduces damage to the environment by generating its own renewable energy. Creating buildings such as these enables us to live in closer harmony with our environment.To meet the needs of today while protecting the world of tomorrow may be a challenge, but even the simplest organisms can help teach us how to achieve this. 1.What’s the author’s purpose in writing the passage?

Research shows that a global shift towards vegetarian(素食的) diets could cut emissions from food system by over half.Even small changes towards plant-based diets can have a meaningful impact.Substituting conventional food with lab-grown alternatives could prevent 1 degree of future warming.These findings demonstrate the power of dietary changes in addressing climate challenges. Dietary choices are influenced by factors like culture，religion，and economics.It is unrealistic to expect everyone to become vegetarian immediately.Respecting individual choices is crucial in promoting sustainable diets.By offering information and raising awareness，individuals can make choices according to their needs and values while contributing to collective efforts. Transforming industrial food production is necessary，but individual choices are still vital.Education and awareness campaigns can inform people about the environmental impact of different dietary choices and empower them to make informed decisions.Combining individual actions with systematic changes can create a powerful force for human health and the planet.Rather than expecting immediate vegetarianism，acknowledging the impact of small changes is important.Gradual shifts towards more sustainable dietary choices，like reducing animal product consumption and increasing vegetable intake，can result in significant environmental benefits when multiplied across populations. In conclusion，addressing climate change requires multiple approaches，with dietary choices playing a crucial role.Offering choices while recognizing the challenges associated with dietary shifts is essential.By combining personal dietary changes with broader efforts to reshape the food system，we can make substantial progress towards a healthier planet while respecting individual preferences. 1.Which is a dietary choice to reduce greenhouse gas emissions?
