七、Read and finish. 本周是学校的“绿色能源宣传周”，宣传栏里有一篇科普文章。请读一读，完成下列任务。
Green energy: gifts from Earth
Wind, sun and water are natural gifts from our Earth. People use them to make green energy. Unlike coal (煤) or oil, green energy is clean and safe. It never makes harmful smoke or pollutes the air, so it keeps our planet healthy and beautiful.
We can use green energy in many smart ways. Wind turbines (涡轮机) spin (旋转) fast in the wind to make electricity, and some trains even run on wind power now. Solar panels (太阳能电池板) on roofs use sunlight to light our homes and heat water for showers. Water power from rivers drives big machines (机器) to make electricity and helps cool our rooms in hot summer.
Green energy makes our life better and protects Earth!
任务一：根据短文内容，将绿色能源与对应的功能连线。（可多选）
● Wind power ● Solar power ● Water power
heat water light homes run trains make electricity cool rooms in summer
任务二：根据短文内容，选择合适的选项。
(
A. coal and oil are also very useful B. green energy is better for the environment
C. we should stop using trains
(
A. explain how trains run B. describe different weather
C. tell us about clean energy and its benefits

解析
【分析】本题为英语阅读理解题，分为任务一连线匹配和任务二单项选择。解题思路：任务一需根据短文内容，分别定位风能、太阳能、水能对应的功能描述，提取匹配项；任务二第1题需对比绿色能源与煤、石油的特点，第2题需归纳全文主旨，均需从原文中查找关键信息作答。
【解析】任务一：1. 定位短文第二段关于风能的描述：“Wind turbines spin fast in the wind to make electricity, and some trains even run on wind power now.” 可知风能对应run trains、make electricity；2. 定位太阳能的描述：“Solar panels on roofs use sunlight to light our homes and heat water for showers.” 可知太阳能对应heat water、light homes；3. 定位水能的描述：“Water power from rivers drives big machines to make electricity and helps cool our rooms in hot summer.” 可知水能对应make electricity、cool rooms in summer。任务二：1. 短文第一段将绿色能源与煤、石油对比，指出绿色能源清洁安全、不产生有害烟雾，目的是说明绿色能源对环境更友好，故选B；2. 全文围绕绿色能源的定义、用途及益处展开，主旨是介绍清洁能源及其好处，故选C。
【答案】任务一：Wind power—run trains, make electricity；Solar power—heat water, light homes；Water power—make electricity, cool rooms in summer；任务二：1. B；2. C
【知识点】英语阅读理解（细节理解、主旨大意）
【点评】本题考查学生的英语阅读理解能力，侧重细节信息查找与文章主旨归纳，属于基础阅读题型，需学生仔细阅读原文定位关键内容即可完成解答。

八、Think and say. 学校正在开展“环保小卫士”讨论赛。请你想一想，以“水力发电清洁无污染”为主题，有条理地阐述观点。
答案
示例：Water power uses running water to make electricity. It's clean. It doesn't produce any harmful waste or dirty gas. It will not pollute the air, the rivers or the land. It is a very green and environment-friendly way to get electricity.
解析
【分析】
首先明确题目要求：围绕“水力发电清洁无污染”的主题，用英语有条理地阐述观点。解题思路：1. 先说明水力发电的基本原理；2. 突出其“清洁无污染”的核心特点，具体说明不产生污染的表现；3. 总结其环保属性，让观点清晰连贯。
