They provide us with food, such as fruits and vegetables, and produce oxygen for us to breathe. Without plants, life would be impossible. Plants also help the environment. They clean the air by absorbing harmful gases and prevent soil erosion by holding the soil with their roots. Besides, they provide homes for many animals. To protect plants, we should plant more trees and avoid cutting them down. We can also save paper by using both sides and recycling. Let's work together to protect plants and make our world greener and healthier. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 2 学科网（北京）股份有限公司 $$………………○………………外………………○………………装………………○………………订………………○………………线………………○……………… ………………○………………内………………○………………装………………○………………订………………○………………线………………○……………… 此卷只装订不密封 ………………○………………内………………○………………装………………○………………订………………○………………线………………○……………… ………………○………………外………………○………………装………………○………………订………………○………………线………………○……………… … 学校：______________姓名：_____________班级：_______________考号：______________________ 2025-2026学年七年级上册英语单元测试 Unit 5·基础卷 学校:___________班级：___________姓名：___________分数：___________ （时间：90分钟，满分：100分） 一、单项选择。(本大题共15小题，每小题1分，共15分) 1.

It grows very fast - some kinds can grow as tall as 90 cm in one day! Bamboo grows mainly in Asia, Africa and South America. People use bamboo in many ways. Its strong stems are used to build houses and bridges. In many Asian countries, people eat bamboo shoots as food. Bamboo also helps the environment by keeping soil healthy and providing homes for animals. An interesting fact: bamboo rarely flowers. Some types flower only once every 100 years!

It changes color B Cacti: Masters of Desert Survival Cacti are incredible plants that thrive (茁壮成长) in dry desert environments where most other plants cannot survive. They have developed unique adaptations to live with very little water. Unlike typical plants, cacti have spines instead of leaves. These sharp spines serve multiple purposes: they reduce water loss by limiting evaporation, and they protect the plant from hungry animals. The thick, waxy skin of cacti acts like a natural water bottle, keeping precious moisture locked inside. Their root systems are equally remarkable. Cacti have wide, shallow roots that spread out just below the desert surface. When rare rains come, these roots quickly absorb as much water as possible. Some large cacti can store thousands of liters of water in their stems, allowing them to survive for years without rain. Despite the harsh conditions, cacti produce stunning flowers when it rains. These flowers attract pollinators and eventually develop into fruits. The plant's bitter taste also helps deter animals from eating it. Cacti teach us valuable lessons about adaptation and making the most of available resources. They show us how to thrive in challenging conditions by using what we have wisely. 31. What is the main purpose of cactus spines? A. To attract pollinators B. To reduce water loss and provide protection C. To store water D. To produce food 32. How do cactus roots help them survive? A. They grow very deep into the ground B. They spread widely to absorb water quickly C. They can store food for the plant D. They change color to avoid animals 33. What special ability do some large cacti have? A. They can walk to find water B. They can store thousands of liters of water C. They can change their shape D. They can produce water 34. When do cacti usually produce flowers? A. During dry seasons B. When it rains C. In winter months D. At night time 35. What lesson can we learn from cacti? A. How to avoid difficulties B. How to use resources wisely C. How to grow faster D.

The Importance of Plants Plants are very important to humans and our environment. They provide us with food, such as fruits and vegetables, and produce oxygen for us to breathe. Without plants, life would be impossible. Plants also help the environment. They clean the air by absorbing harmful gases and prevent soil erosion by holding the soil with their roots. Besides, they provide homes for many animals. To protect plants, we should plant more trees and avoid cutting them down. We can also save paper by using both sides and recycling. Let's work together to protect plants and make our world greener and healthier. 【解析】 [总体分析] ① 题材：本文是一篇说明文，属于环境保护类话题； ② 时态：主要使用一般现在时； ③ 提示：需涵盖所有内容要点，语言简洁准确，适当使用连接词使文章连贯。 [写作步骤] 第一步：开门见山说明植物的重要性，列举人类从植物获取的食物和氧气等基本生存需求； 第二步：具体说明植物对环境的三大作用（净化空气、保持水土、提供栖息地）； 第三步：提出两点保护植物的具体建议（植树造林、节约用纸），并以呼吁行动结尾。​ 原创精品资源学科网独家享有版权，侵权必究！1 8 / 8 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$ 2025-2026学年七年级上册英语单元测试 Unit 5·基础卷 学校:___________班级：___________姓名：___________分数：___________ （时间：90分钟，满分：100分） 一、单项选择。(本大题共15小题，每小题1分，共15分) 1.

They have developed unique adaptations to live with very little water. Unlike typical plants, cacti have spines instead of leaves. These sharp spines serve multiple purposes: they reduce water loss by limiting evaporation, and they protect the plant from hungry animals. The thick, waxy skin of cacti acts like a natural water bottle, keeping precious moisture locked inside. Their root systems are equally remarkable. Cacti have wide, shallow roots that spread out just below the desert surface. When rare rains come, these roots quickly absorb as much water as possible. Some large cacti can store thousands of liters of water in their stems, allowing them to survive for years without rain. Despite the harsh conditions, cacti produce stunning flowers when it rains. These flowers attract pollinators and eventually develop into fruits. The plant's bitter taste also helps deter animals from eating it. Cacti teach us valuable lessons about adaptation and making the most of available resources. They show us how to thrive in challenging conditions by using what we have wisely. 31. What is the main purpose of cactus spines? A. To attract pollinators B. To reduce water loss and provide protection C. To store water D. To produce food 32. How do cactus roots help them survive? A. They grow very deep into the ground B. They spread widely to absorb water quickly C. They can store food for the plant D. They change color to avoid animals 33. What special ability do some large cacti have? A. They can walk to find water B. They can store thousands of liters of water C. They can change their shape D. They can produce water 34. When do cacti usually produce flowers? A. During dry seasons B. When it rains C. In winter months D. At night time 35. What lesson can we learn from cacti? A. How to avoid difficulties B. How to use resources wisely C. How to grow faster D. How to fight enemies 四、补全对话。(本大题共5小题，每小题1分，共5分) 从选项中选择合适的句子，补全对话。其中有二项多余。 Tom: We're studying plants in science class. 36. ______ Lucy: Definitely! Plants give us oxygen to breathe and food to eat.
