What are they made of? Plastic Plastic is widely used in our life and makes our life convenient. However, is plastic always good for us? Look at the picture and answer the questions. 1 Where can you find plastic in the picture? 2 What problems can plastic cause? environmental, waste, ocean, danger, land, break down, air pollution 1 Use the words and expressions to help you. We can find plastic waste in the ocean and on land. It’s also in the air. It pollutes the ocean, land and air. It does not break down easily. Possible answers: It hurts sea animals: The whale eats plastic waste; the turtle gets stuck in plastic nets. Plastic brings us convenience, but it also causes pollution. Is it good or bad? Today we’ll discuss this topic: Plastic: good or bad? 1 When plastic was invented around the 1860s, it was considered an amazing material. It was light, easy to shape, long‑lasting and cheap. It quickly replaced wood and other natural materials. Many people believed plastic would make life better. Back then, some people even saw plastic as an “environmental hero”! 2 Not surprisingly, plastic has now filled our lives. We can find it in bags, bottles, toothbrushes, gloves, mobile phones, cars, houses… you name it. It is certainly convenient and has thousands of uses. Despite all this, it has slowly and quietly shown its dark side. Read the passage and find out whether plastic has made life better or worse. 耐用的 天然材料 以前；从前；当年 环保英雄 充斥我们的生活 凡你说得出的(应有尽有) 暴露其阴暗面/负面影响 2 Plastic good or bad? Plastic waste was first seen in the oceans in the 1960s. Since then, it has become a danger to sea animals. Some animals, such as whales, eat it by mistake and die. The former “hero” kills more than 100,000 sea animals every year. By 2050, there could be even more plastic than fish in the sea by weight. 3 Plastic is also causing problems on land. Birds’ wings get tied in plastic lines. Bears’ heads get stuck in plastic bins. Cows mistake plastic bags for food! Even humans are eating plastic waste! On average, we eat five grams of plastic a week. That’s a whole bank card! Tiny pieces of plastic are found in the air we breathe. They can be carried around by the wind. There is even plastic “snow” at the North and South Poles. On “Planet Plastic”, there is no place free from this. 对海洋动物构成威胁 误食…… 在陆地上 被塑料绳缠住 被塑料垃圾桶卡住 把塑料袋误认为食物 平均来看 微小塑料颗粒 没有任何地方能摆脱它 塑料垃圾 4 Plastic waste is hard to deal with. It may take hundreds of years to break down. Therefore, hiding the waste in the ground doesn’t solve the problem. Burning it also produces thick smoke that causes air pollution. 5 Plastic makes life easier for many people, yet it brings long-lasting troubles to our planet. Our choices today change the world tomorrow. With no Planet B to turn to, we must think clearly and use plastic wisely. 它可能需要数百年才能(自然)分解。 把废物/垃圾埋在地下 解决问题 造成空气污染 给我们的地球带来长久的麻烦 明智地使用塑料 What's the genre(体裁) of the passage? A. A story B.

Why? Possible answers: I find the problem on land most shocking, because humans are eating plastic — five grams a week, that’s a whole bank card! I never thought plastic could enter our bodies. Task 6 Learning to think for question 2 To think about the future of plastic, you should consider things like environmental problems, new technologies and how people feel about plastic. 2 Do you think humans will ever stop using plastic? Why or why not? Option A： I don't think humans will ever completely stop using plastic, because it is too convenient and cheap. We use it in almost everything — bags, bottles, phones, cars. It is hard to find good replacements for all these things. Option B： I think we can greatly reduce plastic use, even if we cannot stop it completely. More and more people are becoming aware of the problem. We can use reusable bags, bottles, and say no to single-use plastic. How can we use plastic wisely in daily life? Use cloth bags instead of plastic bags. Try not to buy goods with too much plastic packaging. Say no to plastic straw. Recycle plastic correctly. Bring our own lunch boxes. ... 1.
