For example, a battery uses chemical reactions _______ (2) (produce) electricity, which is a form of energy. We also learned about motors, _______ (3) use electromagnetic principles (电磁原理) from physics to turn electricity into motion. Our teacher asked us to design a model car that runs on solar power. It required both technical skills from science and creative design from art. ________ (4) (work) together, we realized that different subjects often _______ (5) (connect) in real-life problems. 五、完形填空 阅读下面短文，从A、B、C、D四个选项中选出最佳选项。 Cross-curricular learning means connecting different subjects. In a project about electricity, students might use math to calculate energy consumption, physics to explain ________ (1) it works, and art to design posters about saving energy. This helps them see the _______ (2) between subjects. For example, when studying how a generator works, students learn about magnetism (磁性) in physics and the role of coils (线圈) in math. They also discuss the environmental impact of power stations in ______ (3) class. Such connections make knowledge more ______ (4) and help students solve complex problems. So, cross-curricular activities are a great way to develop ______ (5) thinking skills. 1. A. when B. how C. where D. why 2. A. differences B. problems C. connections D. difficulties 3. A. history B. math C. physics D. geography 4. A. boring B. real C. interesting D. easy 5. A. single B. creative C. strange D. traditional 六、任务型阅读 阅读短文，根据短文内容回答问题。 Cross-curricular Connection: Electricity in Different Subjects Electricity is not just a topic in science class — it connects to many other subjects: Physics: Studies how electricity is generated, like through electromagnetic induction (电磁感应) in generators. Math: Involves calculating voltage (电压), current and power using formulas. Chemistry: Explores how batteries produce electricity through chemical reactions. Geography: Discusses where power stations are built and their impact on the environment. Art: Designing posters or models to promote energy-saving ideas. By linking these subjects, students can understand electricity more deeply. For example, a science project about solar panels might require math to calculate efficiency, geography to study sunlight patterns, and art to present findings visually. This helps develop well-rounded thinking. 1. What does physics study about electricity? 2. How does chemistry explain electricity production? 3. Which subject discusses the environmental impact of power stations? 4. What can art do to promote energy-saving ideas? 5. Why is cross-curricular learning useful for understanding electricity? 参考答案： 一、短语翻译 1. cross-curricular connection 2. energy transformation 3. physical principle 4. depend on 5. be related to 二、根据句意及首字母提示或汉语提示完成单词 1. connections 2. transformation 3. physical 4. depends 5. related 三、句型转换 1. Why do 2. changed into 3. Is; about 4. depend on 5. is connected 四、语法填空 1. to 2. to produce 3. which 4. Working 5. are connected 五、完形填空 1--5. BCDCB 六、任务型阅读 1. It studies how electricity is generated, like through electromagnetic induction in generators. 2. It explores how batteries produce electricity through chemical reactions. 3. Geography. 4. Designing posters or models. 5. Because it helps students understand electricity more deeply and develop well-rounded thinking. 学科网（北京）股份有限公司 $$
