阅读下面的材料，从每小题所给的A、B、C、D四个选项中选出最佳选项。
Solar Power
Solar power,as a clean and renewable energy,uses sunlight to create electricity for millions of people in China. We can collect sunlight with solar panels(面板). They are often placed on roofs of houses or in large fields. In faraway and undeveloped(不发达的) areas,it's quite difficult to build traditional power grids(电网) and that costs a great deal of money. Solar power systems are great ways to solve these problems,and they can provide energy for people's daily life and work.
Solar power has many advantages. First of all,it's a typical green energy source — unlike burning coal or oil,solar power doesn't give out any harmful things,such as CO₂,when it works. Second,sunlight is free and never runs out. Many countries are now using more solar power to reduce air pollution.
However,solar power also has some limits. It cannot work well on cloudy or rainy days because there is not enough sunlight. Also,solar panels are not cheap to buy. But as technology improves,these problems are slowly being solved.
Solar power is becoming more popular. It helps us protect the Earth while meeting our energy needs. With the development of technology and policy support,solar power is expected to play an even more important role in building a sustainable(可持续的) future for us.
1. What is solar power used for according to the passage?
A. Heating water.
B. Growing plants.
C. Making electricity.
D. Cleaning the air.
2. Why are solar power systems widely used in faraway places?
A. Because they can turn sunlight into electricity.
B. Because they provide clean and renewable energy.
C. Because they can be placed on roofs of houses or in large fields.
D. Because building the power grids is difficult and expensive.
3. Why is solar power good for the environment?
A. It is cheap to use.
B. It works on rainy days.
C. It produces no pollution.
D. It needs little space.
4. What does the underlined word "limits" mean?
A. 好处
B. 局限性
C. 资源
D. 功能
5. What is the main idea of the passage?
A. Solar panels are very expensive.
B. Solar power only works in sunny days.
C. Solar power will replace all other energy sources.
D. Solar power is a clean energy with both advantages and disadvantages.

解析
【分析】
这是一篇科普类说明文阅读理解，解题时首先可以先快速通读全文，理清文章脉络：先介绍太阳能的基本用途，再讲它的优势、现存不足，最后说明它的发展前景。之后每道题带着题干的关键词回到原文对应段落定位，细节题直接匹配原文信息，词义猜测题结合前后文逻辑推导，主旨题综合全文内容排除片面的错误选项，就能选出正确答案。
【解析】
1. 细节题：定位原文第一段第一句“Solar power,as a clean and renewable energy,uses sunlight to create electricity for millions of people in China”，明确说明太阳能的作用是发电，对应选项C。
2. 细节题：定位原文第一段“In faraway and undeveloped(不发达的) areas,it's quite difficult to build traditional power grids(电网) and that costs a great deal of money. Solar power systems are great ways to solve these problems”，可知偏远地区广泛使用太阳能系统是因为建造传统电网难度大、成本高，对应选项D。
3. 细节题：定位原文第二段“it's a typical green energy source — unlike burning coal or oil,solar power doesn't give out any harmful things,such as CO₂,when it works”，可知太阳能运行时不会排放有害物质，完全无污染，对环境友好，对应选项C。
4. 词义猜测题：划线词后文介绍了太阳能的两个问题：阴雨天无法正常工作、太阳能面板购置成本不低，这些都是太阳能目前的不足，因此limits的含义是局限性，对应选项B。
5. 主旨大意题：全文既介绍了太阳能清洁、可再生等诸多优势，也提到了它现存的不足，说明它是一种优缺点并存的清洁能源。A、B都是文章的局部细节，C选项文中没有提及“取代所有其他能源”的表述，只有D能概括全文核心内容。
【答案】
1.C 2.D 3.C 4.B 5.D
【知识点】
阅读细节查找，词义猜测，主旨大意判断
【点评】
本题属于难度适中的科普类阅读题，绝大多数细节题都可以通过原文直接定位得到答案，仅词义猜测和主旨类题目需要结合上下文逻辑推导，既可以锻炼学生快速抓取文本关键信息的能力，也能帮助学生了解清洁能源相关的科普常识。
