Unit 6 Living with nature Understanding ideas 同步习题 一、阅读理解 阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出最佳选项。 ① In recent years, scientists have been working on a breaking technology that could change the way we think about solar energy: solar paint. Unlike traditional solar panels（板）, which are huge and expensive, solar paint is a lightweight material that can be painted on almost any surface. This creation could turn the whole buildings into energy providers, making green energy much more available than ever before. ② Solar paint works by using tiny particles called photovoltaic cells（光伏电池）, which take in sunlight and change it into electricity. These cells are mixed into a liquid solution（溶液）that can be brushed onto walls, doors, or even windows. Once brushed, the paint begins to produce power at once. ③ One of the most exciting things of solar paint is its potential（潜力）to cut carbon emissions（碳排放）. Traditional energy like coal and oil is the main cause for climate change. By covering buildings with solar paint, cities could greatly cut their dependence on traditional energy and move closer to a green future. ④ Researchers believe that a single coat of solar paint could produce enough energy to power a small piece of household equipment. ⑤ ▲ . Now, solar paint is less efficient than traditional solar panels, and it is more expensive to produce. Scientists are working to improve its efficiency and lower costs, but it may take several years before solar paint becomes widely available. ⑥ Although there are such challenges, the potential of solar paint is unstoppable. As technology develops, it could become a key tool in the fight against climate change, deeply changing the way we power our homes and cities. ( ) 1. What is the main material of solar paint that allows it to produce electricity? A. Liquid solution. B. Photovoltaic cells. C. Traditional solar panels. D. Sunlight that's taken in. ( ) 2. What can be inferred from the passage? A. Climate change can be stopped by using solar paint. B. Cities don't need to use traditional energy any more. C. It is not yet ready for the wide use of solar paint. D. Solar paint is less efficient than traditional energy. ( ) 3. Which of the following can be put into the ▲? A. However, there are still some challenges to overcome B. Solar paint is also praised for some other advantages C. The power energy produced by solar paint can help us live a low ( ) 4. What's the best structure of the passage? A. Solar Paint ①—②—③④—⑤—⑥ B. Solar Paint ①—②—③—④⑤—⑥ C. Solar Paint ①—②③—④⑤⑥ D. Solar Paint ①—②③④—⑤⑥ 二、短文还原 阅读短文，从短文下面方框中的六个句子中选择五个还原到短文中，使短文通顺完整、衔接自然。 Life in 2050: A Glimpse into Tomorrow Smart Transportation Getting around will be safer and greener.
