The effects of smog on the environment. How governments try to reduce smog. What will happen if we don’t reduce smog. Lecturer: Good evening, everyone, and thank you for coming to today’s talk. I’m Dr Brown and I’m going to talk about air polution in cities—what we all know as “smog”. Please feel free to stop me if you have any questions. So, first of all, a bit of history. The term “smog” was first used in the 1800s in cities that had problems with smoke and fog. Student A: Sorry for interrupting, but I believe it was in the 1900s. Lecturer: Sorry, I made a mistake. You are right. It was in the 1900s. Thank you. London was one of the cities where smog caused big problems. In December 1952, it suffered from “The Great Smog”. It was a very cold winter, so a lot of coal was burned at home and in the factories. The problem was that there was no wind, so thick smog covered the city. Nowadays... Student B: Excuse me, but can I just ask—did the smog cause any deaths? Lecturer: I’m afraid so. According to research, about 4,000 people are known to have died as a result of the smog, but that number could be much higher. It was terrible! Nowadays, smog still exists, but is produced by chemicals coming from traffic and factories. However, governments are taking measures to reduce smog as much as possible. Now, let’s look at what smog does to our health... Student A: If I could just stop you again... Can you give us examples of these measures? Lecturer: Well, for example, factories must follow rules about what chemicals they use. In some cities, when there’s smog, people have to pay to drive in the centre. Now, let’s move on to the impact of smog on our health... While-listening Listen to the lecture and choose the topics that are covered. Listening for specific information What causes smog now.

Listening for speaking Post-listening Student A Tell Student B about recycling using the information below. Be prepared to be corrected by Student B. • The classification of household waste aims to help people separate different types of waste. This is important because these different types of waste can be disposed of or recycled appropriately and effectively. • Household waste can be roughly divided into: * food waste * non-recyclable waste * recyclable waste, including paper, glass, plastic and used batteries • China plans to introduce household waste classification and sorting in the first batch of cities by 2020. Only Beijing, Shanghai, Tianjin and Chongqing are included in the first batch. • The target recycling rate in these cities has been set at 55% by 2020. Work in pairs and talk about recycling. Listening for speaking Post-listening Student B Listen to Student A talking about recycling. Interrupt politely to correct him / her using the following information: • Used batteries are usually regarded as non-recyclable waste and should be disposed of separately. • The first batch of cities to introduce household waste classification and sorting includes Beijing, Shanghai, Tianjin, Chongqing and all capitals of provinces and autonomous regions. • The target recycling rate in these cities has been set at 35% by 2020. Student A: Good evening, everyone, and thank you for your coming to today’s talk. I’m going to talk about recycling. Please feel free to stop me if you have any questions. The classification of household waste aims to help people separate different types of waste. This is important because these different types of waste can be disposed of or recycled appropriately and effectively. Household waste can be roughly divided into: food waste, non-recyclable waste and recyclable waste, including paper, glass,plastic and used batteries. Sample Student B: Sorry to interrupt, but used batteries are usually regarded as non-recyclable waste and should be disposed of separately. Student A: Sorry, I made a mistake. You are right. China plans to introduce household waste classification and sorting in the first batch of cities by 2020. Only Beijing, Shanghai, Tianjin and Chongqing are included in the first batch. Student B: Excuse me. Can I ask another question? You mentioned that only four cities are included in the first batch of cities to introduce household waste classification and sorting. But I remember that apart from these four cities, all capitals of provinces and autonomous regions are included in the first batch of cities. Is that right? Student A: I am sorry, I’ve made another mistake. You are right. Now, let’s go back to what I was talking about. The target recycling rate in these cities has been set at 55% by 2020. Student B: Sorry, but could I just stop you again to check about the target recycling rate?I’m wondering whether the target recycling rate should be 35% or 55% by 2020? Student A: Well, let me see. Yes, you are right. I am sorry again for making the mistake. Thanks for correcting all my mistakes. Student B: You are welcome. Work in pairs. Talk about another environmental problem and have a similar conversation. Listening for speaking Post-listening Thank you! $$
