It affects not only the health of humans but also the survival of plants and animals. Understanding the causes and effects of water pollution is the first step toward solving this problem. There are many causes of water pollution. One of the main causes is industrial waste. Factories often release chemicals and heavy metals into rivers and lakes without proper treatment. These substances can be very harmful to living organisms. Another major cause is agricultural runoff. Farmers use fertilizers and pesticides to increase crop production. When it rains, these chemicals are washed into nearby water bodies, causing pollution. Household waste is also a significant contributor. Many people throw garbage and plastic into rivers, which not only pollutes the water but also harms aquatic life. The effects of water pollution are severe and far-reaching. Polluted water can cause many diseases in humans, such as cholera and typhoid. It also kills fish and other aquatic animals, disrupting the food chain. Moreover, water pollution makes water unfit for drinking, bathing, and farming. This can lead to water shortages and food scarcity in many regions. In conclusion, water pollution is a global problem that requires immediate attention.

I have been a volunteer for an environmental protection organization for three years. During this time, I have participated in many activities aimed at protecting the environment. Today, I want to share one of my most memorable experiences with you. Last summer, our team organized a river clean-up activity in my hometown. The river used to be clean and clear when I was a child. However, in recent years, it has become heavily polluted. People had been throwing garbage and pouring wastewater into it for a long time. The water turned dark and smelly, and the fish disappeared. The local community was worried about the situation and wanted to do something to help. On the day of the activity, more than fifty volunteers came together. We spent the whole morning cleaning up the riverbanks. We collected plastic bottles, bags, and all kinds of trash. Some volunteers even used nets to remove floating garbage from the water. By the end of the day, we had collected dozens of bags of waste. It was hard work, but we all felt very proud. Since that day, the community has taken better care of the river. People have stopped throwing garbage into it. Now, the water is much cleaner and you can see fish swimming in it again. This experience taught me that small actions can make a big difference. I believe that if everyone does their part, we can protect our environment and create a better world for future generations. 6．How long has Chen Wei been a volunteer? A．One year. B．Two years.

A new study said that by 2040, microplastic pollution could be twice as bad as it is now. Scientists learned this by looking at 20 years of studies on microplastics. Microplastics come from many places. For example, about 60 percent of material made into clothing is plastic. Every time they are washed, they shed (掉落) microplastics. When water bottles and other big plastic items are left outside, they break down slowly into microplastics. They do great harm to the environment as well as the health of animals and humans. However, it is really hard to clean up microplastics. Firstly, they are small bits of plastic less than 5mm long. Besides, they stay nearly everywhere. They’ve been found in our oceans, on the top of mountains, in some of the food we eat and even in the stomachs of some ocean animals. What’s more, they don’t break down easily and can stay in the environment for hundreds of years. This can be bad for our health. In August, The Conversation reported that scientists found microplastics in people’s brains for the first time. They may hurt brain cells. They can even change how the brain works. Wild animals are also at risk from microplastic pollution. Each year, up to three million tons of microplastics end up in the ocean. Since they are too small to be seen, fish may eat them by mistake and become very sick. 根据语篇内容，按要求回答问题。 1．What can microplastics bring? 2．Where do microplastics mainly come from? 3．Why are microplastics difficult to clean up? (不超过15个词) 4．How do microplastics influence people’s brains? 5．Write an ending sentence for the passage. (不超过15个词) 【答案】 1． Big pollution problems. 2．Clothing and plastic items. 2． Because they are small, stay everywhere and don’t break down easily. 3． They may hurt brain cells and change how the brain works. 5．To deal with the problem, we should make and use less plastic. 【导语】本文是一篇说明文。文章主要讲述了微塑料的来源、难以清理的原因以及对人类健康和野生动物造成的危害，呼吁人们关注微塑料污染问题。 【详解】1．第一段首句直接写明“Microplastics (微塑料) are very small, but they can bring big pollution problems.”。这是原文中的核心信息，直接提取。 2．第二段总起句写明“Microplastics come from many places”后文举例“about 60 percent of material made into clothing is plastic... When water bottles and other big plastic items are left outside, they break down slowly into microplastics.”，说明衣物洗涤、大型塑料物品风化分解是微塑料的两个主要来源，整合两处原文内容即为答案。 3．第三段依次列出三点原因“less than 5mm long、stay nearly everywhere、don’t break down easily”，将三点原文信息精简概括，且控制在15词内即可。 4．第四段末尾直接给出微塑料对大脑的影响：“They may hurt brain cells. They can even change how the brain works.”。答案几乎是原文引述。 5．本题是开放性试题，答案不唯一，但句子需贴合微塑料污染的主题，同时不超过15个单词，表述通顺合理即可。 $ Unit 2 Greener Planet, Better Home 课时6 Oral Communication分层作业 A组 巩固过关 C组 思维拔高 B组 能力进阶 拓展 链接中考 ( 词汇 1 .take good care of 悉 心照料 2 . think twice三思 3 . take the undergrou n d 乘坐地铁 4 . as much as possible 尽可能多地 5 .

It affects not only the health of humans but also the survival of plants and animals. Understanding the causes and effects of water pollution is the first step toward solving this problem. There are many causes of water pollution. One of the main causes is industrial waste. Factories often release chemicals and heavy metals into rivers and lakes without proper treatment. These substances can be very harmful to living organisms. Another major cause is agricultural runoff. Farmers use fertilizers and pesticides to increase crop production. When it rains, these chemicals are washed into nearby water bodies, causing pollution. Household waste is also a significant contributor. Many people throw garbage and plastic into rivers, which not only pollutes the water but also harms aquatic life. The effects of water pollution are severe and far-reaching. Polluted water can cause many diseases in humans, such as cholera and typhoid. It also kills fish and other aquatic animals, disrupting the food chain. Moreover, water pollution makes water unfit for drinking, bathing, and farming. This can lead to water shortages and food scarcity in many regions. In conclusion, water pollution is a global problem that requires immediate attention. Everyone can play a part in reducing water pollution by adopting greener habits in their daily lives. 1．What is the main topic of this passage? A．The importance of clean water.

I have been a volunteer for an environmental protection organization for three years. During this time, I have participated in many activities aimed at protecting the environment. Today, I want to share one of my most memorable experiences with you. Last summer, our team organized a river clean-up activity in my hometown. The river used to be clean and clear when I was a child. However, in recent years, it has become heavily polluted. People had been throwing garbage and pouring wastewater into it for a long time. The water turned dark and smelly, and the fish disappeared. The local community was worried about the situation and wanted to do something to help. On the day of the activity, more than fifty volunteers came together. We spent the whole morning cleaning up the riverbanks. We collected plastic bottles, bags, and all kinds of trash. Some volunteers even used nets to remove floating garbage from the water. By the end of the day, we had collected dozens of bags of waste. It was hard work, but we all felt very proud. Since that day, the community has taken better care of the river. People have stopped throwing garbage into it. Now, the water is much cleaner and you can see fish swimming in it again. This experience taught me that small actions can make a big difference. I believe that if everyone does their part, we can protect our environment and create a better world for future generations. 6．How long has Chen Wei been a volunteer? A．One year. B．Two years. C．Three years. D．Four years. 7．What was the condition of the river before the clean-up? A．It was clean and clear. B．It was heavily polluted. C．It was full of fish. D．It was used for swimming. 8．What did the volunteers do during the activity? A．They planted trees along the river. B．They cleaned up the riverbanks and removed garbage. C．They built a new bridge. D．They painted the riverbanks. 9．What has happened to the river since the clean-up? A．It has become more polluted. B．People have stopped throwing garbage into it. C．The fish have all died. D．The water has turned dark again. 10．What lesson did Chen Wei learn from this experience? A．Cleaning rivers is a waste of time. B．Small actions can make a big difference. C．Only volunteers can protect the environment. D．The river will never be clean again. 三、补全对话 根据下面的对话情景，在每个空白处填上一个恰当的句子，使对话的意思连贯、完整。 A: Hi! You are carrying a cloth bag. 1 ?
