目标二：To learn how to interrupt others politely and know how to recycle.

Activity 1: Now talk about what the students say to interrupt the lecturer politely. Listen again if

necessary.

Lecturer: Good evening, everyone, and thank you for ing to today's talk. I'm Dr Brown and I'm

going to talk about air pollution 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.

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 ing 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

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

and effectively.

• Household waste can be roughly divided into:

* food waste

* nonrecyclable 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.
