Learning Objectives Warming Up Look and guess. After watching the video, how do you feel about the Yangtze River? 点击播放视频 beautiful, important... Reading Pre-reading 1a Discuss the questions to share what you know about water pollution. What are the causes of water pollution? How does water pollution affect people’s lives? Factories pour waste into rivers. People throw rubbish like plastic bags into rivers. Ships spill oil into the sea. We can get sick if we eat polluted fish or drink dirty water. We cannot use dirty water for cooking, washing, or swimming. Fishermen lose their jobs because fish die. The Yangtze River and Its Guardians Every morning, 53-year-old Chen Ming walks 15 kilometres along the Yangtze River. As he does so, he often stops to talk to the people picnicking beside the water or to watch the birds catch fish in the river’s clear water. While one might think that he is just out for exercise, he is actually working: Mr Chen is a “Guardian of the River”. His job is to walk along the river and make sure that no one is fishing in it or polluting it. Mr Chen was not a “Guardian of the River” before. He grew up on the banks of the Yangtze River and used to be a fisherman, like his father. Back then, parts of the river were smelly and yellow because of the waste from factories and homes. Fishermen were also catching too many fish. As a result, the number of fish and plants in the river was dropping quickly. The government took action to deal with the problem before it was too late. New waste centres were built to clean the wastewater before it went into the river. Laws were made to stop new factories from being built near the river. Boats were sent out to clean up the rubbish. Finally, fishing was banned in the Yangtze River for 10 years from 2020. Mr Chen and other fishermen were given new jobs as guardians to protect the river. At first, Mr Chen was not used to working on the riverbank. Now he feels happy because he has a good job and a steady income. He is also glad to see that the Yangtze River has returned to what it used to be like when he was a child, with a lot of fish swimming in the clear water and beautiful birds enjoying their life on the bank. He is proud of his job. “Look there! That’s my wife,” Mr Chen said to the reporter. “She has joined a river clean-up team, and we work together to protect our mother river. We must protect it for our future generations.” Let’s skim! While-reading Q: Based on the title, what do you think this passage will mainly talk about? (Answer in your own words.) The passage will probably talk about the Yangtze River and the people who protect it.

Paragraph 1 Paragraph 2  Paragraph 3  Paragraph 4 A. Why we need to deal with the problem now   B. Examples of how we can use less plastic    C. Why plastic is a problem    D. The benefits of plastic The Problem with Plastic Plastic is one of the most useful materials in the world. It provides many benefits to our lives because it is cheap and convenient. For example, two or three hundred years ago, clothes were quite expensive, so many people only had one or two sets of clothes to wear. Now, with plastics like nylon and polyester, clothes have become much cheaper. Plastic can also be used to replace other things that are rare or valuable. For example, things like piano keys, which were once made from ivory, are now usually made from plastic. This saved the lives of many elephants. However, while plastic has many benefits, it also causes lots of problems. Some plastic is so strong that it takes more than 400 years to break down before returning safely to the environment. When plastic is put in a landfill, the harmful materials inside can get into the soil and water underground. When plastic rubbish is burnt, it fills the air with harmful gas. Another problem is that plastic rubbish is often thrown on the ground. Rain washes that rubbish into the rivers. From there, it is swept out to the sea. Sea animals can get caught in it or hurt by it. Worse yet, sometimes fish eat the plastic as food, and it gets into their bodies. When the fish get to our dining table, the plastic would get into humans’ bodies and harm our health. Check your answer. Paragraph 1 Paragraph 2  Paragraph 3  Paragraph 4 A. Why we need to deal with the problem now   B. Examples of how we can use less plastic    C. Why plastic is a problem    D. The benefits of plastic What can we do about this problem? The best solution, for now, is to use less plastic. For example, bring your own reusable bag when shopping. Buy products, such as clothing and toothbrushes, made of natural materials.

The Problem with Plastic Plastic is one of the most useful materials in the world. It provides many benefits to our lives because it is cheap and convenient. For example, two or three hundred years ago, clothes were quite expensive, so many people only had one or two sets of clothes to wear. Now, with plastics like nylon and polyester, clothes have become much cheaper. Plastic can also be used to replace other things that are rare or valuable. For example, things like piano keys, which were once made from ivory, are now usually made from plastic. This saved the lives of many elephants. However, while plastic has many benefits, it also causes lots of problems. Some plastic is so strong that it takes more than 400 years to break down before returning safely to the environment. When plastic is put in a landfill, the harmful materials inside can get into the soil and water underground. When plastic rubbish is burnt, it fills the air with harmful gas. Another problem is that plastic rubbish is often thrown on the ground. Rain washes that rubbish into the rivers. From there, it is swept out to the sea. Sea animals can get caught in it or hurt by it. Worse yet, sometimes fish eat the plastic as food, and it gets into their bodies. When the fish get to our dining table, the plastic would get into humans’ bodies and harm our health. What can we do about this problem? The best solution, for now, is to use less plastic. For example, bring your own reusable bag when shopping. Buy products, such as clothing and toothbrushes, made of natural materials. Avoid buying products with plastic packaging. Say no to single-use plastic items—plastic spoons and forks, plastic food containers and straws, etc. While plastic is convenient and useful, in the end, most of it will last longer on our planet than we will. Let us not leave this problem to our future generations when we can deal with it now. 1. What are the benefits of plastic? Plastic is cheap and convenient. It makes clothes much cheaper.
