中考真题2025年陕西省阅读理解A- 树木：城市的“省钱小帮手”
Most people agree that trees look nice. But not too many people know trees can also help us save money. Environmental scientists did some research and they learned that just one tree can save a city about 2,800 yuan over the tree’s lifetime.
One way trees save money is by helping us save energy. Big trees stop the summer sun from shining directly to the buildings. Big trees block the winter wind. In this way, they help people to save the energy to make their homes and offices cool or warm. Saving energy means saving money!
There are other ways for trees to help a city save money. For example, when it rains, a city’s sewers fill up with water. Cities have to spend lots of money cleaning that water. But trees’ leaves and roots take in rainwater before it gets to the dirty sewers. With the help of trees, there is less water to clean and money is saved.
1.1. What does the passage mainly talk about?
A How to protect trees.
B How to study trees.
C How trees help cities save money.
D How trees make cities look nice.
解析：选C。C。主旨大意题。全文开篇点明“trees can also help us save money”，后文围绕“节省能源”“处理雨水减少清洁费用”展开，核心是树木帮城市省钱的方式；A（保护树木）、B（研究树木）、D（树木让城市美观）均非核心内容，仅开篇提及“look nice”作为引子。
2.2. The underlined word “they” refers to “______”.
A city cleaners
B environmental scientists
C big trees
D tall buildings
解析：选C。C。词义猜测题。划线词“they”位于第二段第三句，前文明确提到“Big trees stop the summer sun... Big trees block the winter wind”，此处“they”指代前文的“big trees”，承接前文说明大树节省能源的作用；A（城市清洁工）、B（环境科学家）、D（高楼）均与上下文逻辑不符。
3.3. To better support the topic sentence of Paragraph 3, the writer ______.
A gives an example
B asks a question
C uses pictures
D lists numbers
解析：选A。 A。句意理解题。第三段主题句为“There are other ways for trees to help a city save money”，后文用“For example”引出雨水处理的具体案例，通过举例支撑主题句；B（提问题）、C（用图片）、D（列数字）均未在该段体现。
