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 pollution in cities—what we all
know as “smog”. Please______________________ 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: ______________________, but I believe it was in the 1900s.
Lecturer: Sorry, I made a mistake…The problem was that there was no wind, so thick
smog covered the city. Nowadays...
Student B: ________________________—did the smog cause any deaths
Lecturer: I’m afraid so. According to research, about 4,000 people are known…
Sorry, for interrupting
feel free to stop me
Task 4: Listen again and complete the dialogue.
Excuse me, but can I just ask
…
Now, let’s look at what smog does to our health...
Student A: _________________________...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...
If I could just stop you again
Learning to learn:
A polite interruption is usually framed as a request for permission to interrupt someone, often starting with If..., May I... or Can I... This may be preceded with an apology such as Sorry, ... or Excuse me, ... Usually we interrupt someone when they pause for breath, or during the slight pause between spoken clauses.

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...
