Students will love exploring while also gaining invaluable experience by designing and conducting experiments. 素能提升练 Sunscreen Experiment Kids often don't enjoy being told they need sunscreen，so showing its power through demonstration can help them see its value. This science fair project uses simple white beads (珠子) that change color when exposed to UV rays (紫外线) so children can compare the effectiveness of different sunscreen products. Start this experiment by applying some of each sunscreen type on paper and placing both pieces of paper in direct sunlight for several hours. Sundial (日晷) Experiment Using a sundial to tell time is a fascinating science activity that helps students gain knowledge of shadows and the movement of sunlight across the sky. Through this hands-on experiment，students gain an opportunity to see how people in previous times knew time without clocks or watches. Start this experiment by asking students to identify an outdoor spot that receives sunlight all day，placing a flat board there，tracing the shadows onto it and noting where the shadows will fall at certain points of the day. Mineral Experiment Students learn to identify rocks and minerals through this simple experiment. They use a plate to test the hardness of various common minerals. They also observe how these minerals form crystals (晶体) and how they break apart differently from others. This lesson helps students understand the characteristics and uses of different minerals. Students can even form “companies” and compete to mine different types of rocks with specific features. 语篇解读　本文是一篇应用文。文章介绍了几个适合学生做的科学实验。 1．What is the main purpose of using beads in the sunscreen experiment？ A．To compare the prices of sunscreen. B．To show the effectiveness of sunscreen. C．To analyze the impact of sunscreen on skin. D．To demonstrate chemical reactions in sunscreen. √ 细节理解题。根据Sunscreen Experiment下的“This science fair project uses simple white beads (珠子) that change color when exposed to UV rays (紫外线) so children can compare the effectiveness of different sunscreen products.”可知，在防晒实验中使用珠子的主要目的是来展示防晒霜的功效。故选B项。 2．How do students begin the sundial experiment？ A．By building a sundial from beginning. B．By comparing different types of sundials. C．By measuring the length of their shadows. D．By identifying a sunny spot and using a flat board. √ 细节理解题。根据Sundial(日晷)Experiment下的“Start this experiment by asking students...will fall at certain points of the day.”可知，学生找一个阳光充足的地方，用一块平板来开始日晷实验。故选D项。 3．What does the mineral experiment allow students to do？ A．Observe crystal formation. B．Learn geological history. C．Sell rocks they mine. D．Form companies. √ 细节理解题。根据Mineral Experiment下的“They also observe how these minerals form crystals (晶体) and how they break apart differently from others.”可知，Mineral Experiment允许学生观察晶体形成。故选A项。 B How can a large city find water for 10 million people if it is in the desert？ Fog-catching nets on hills around the city of Lima，the capital of Peru，could solve the city's water shortages for good.A twenty-meter high net tower will soon be displayed in the city as a solution to the problem. Peru's capital city has just one inch of rain a year.The city sees high annual temperatures and water consumption rates.Located in a desert，the city's temperatures are higher than world averages.However，a unique feature of Lima's weather offers a way of meeting some of this demand.Located on the coast，Lima's surrounding hills are constantly bathed in waves of fog coming off the Pacific Ocean，and the moisture (湿气) taken in by plants ensures they stay green year-round. Inspired by fog nets placed by rural communities across the continent，Alberto Fernandez，a Chilean architect currently studying for a Ph.D.from University College London，has designed a series of towers and fog-catching nets.They can collect as much as 1，000 liters of water per day，amounting to 3.6 million liters per year，if enough are put into use.Their towering structure allows them to get into the clouds，collecting more vital water vapor (蒸气)，and their unique shape means that no matter the direction of the wind，the moisture-rich fog will strike some part of the structure directly. The water will largely be used for agriculture—as the water would require filtering (过滤) before consumption—helping free up resources for city residents.Cheaper than filtering water from the Rimac River，these towers and nets，which Fernandez says could be built up to 200 meters high，are part of a series of designs for the Lima 2035 project.It aims to change current desertification and create a new place for sustainable and human-centered food systems that promote healthy diets and improve incomes in the driest city on Earth. 语篇解读　本文是一篇说明文。文章介绍了秘鲁的首都利马这座地球上最干旱的城市如何通过安装捕雾网来解决水资源短缺的问题。 4．What makes plants in Lima stay green year-round？ A．The heavy rainfall. B．The high temperature. C．The net tower. D．The unique location. √ 细节理解题。根据第二段中“Located on the coast，Lima's surrounding hills are constantly bathed in waves of fog coming off the Pacific Ocean，and the moisture (湿气) taken in by plants ensures they stay green year-round.”可知，利马位于海岸的独特位置让其可以笼罩在雾浪中，让植物全年保持绿色。故选D项。 5．What does Fernandez draw inspirations from？ A．The direction of the wind. B．The moisture-rich fog. C．The height of the tower. D．The fog-catching net. √ 细节理解题。根据第三段中“Inspired by fog nets placed by rural communities across the continent，Alberto Fernandez，a Chilean architect currently studying for a Ph.D.from University College London，has designed a series of towers and fog-catching nets.”可知，Fernandez的灵感来自农村社区放置的捕雾网。故选D项。 6．What will Fernandez's design mainly help to do？ A．Supply drinking water. B．Turn desert into rich soil. C．Increase food production. D．Develop healthy lifestyles. √ 细节理解题。根据最后一段中“The water will largely be used for agriculture—as the water would require filtering (过滤) before consumption—helping free up resources for city residents.”和“It aims to change current desertification and create a new place for sustainable and human-centered food systems that promote healthy diets and improve incomes in the driest city on Earth.”可知，Fernandez的设计主要将帮助为农业提供用水，提高当地的粮食产量。故选C项。 7．Which of the following would be a suitable title for the text？ A．Fog-catching towers help solve water shortage B．The driest city on Earth faces a serious problem C．Fernandez designed the first fog-catching net D．Water plays a role in a sustainable food system √ 标题归纳题。通读全文，尤其根据第一段内容可知，文章围绕利马通过安装捕雾网来解决水资源短缺的问题展开，介绍了利马的地理位置使得雾气成为一种宝贵的水资源，设计师利用这一特点设计了高耸的塔和捕雾网，每天可以收集大量的雾水，为城市提供稳定的水源。这些收集的水将主要用于农业，为城市居民提供一种可持续的水资源解决方案。因此，A项“捕雾塔有助于解决水资源短缺问题”最适合作为文章标题。故选A项。 Ⅱ.完形填空(每小题1分，共15分) (2025·辽宁抚顺开学考试) Seven years ago，Naaz Ozair's life took a heartbreaking turn when he lost his young nephew to cancer.
