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 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…
打扰，打断
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…
采取措施
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…
Please preview the passage in P62 and do the exercises in P64.
