A Sandy is reading a newspaper. Decide which headlines are about emergencies (E) and which are about natural disasters(ND).

B Sandy and Millie are chatting online about emergencies and natural disasters. Work in pairs and talk about an emergency or a natural disaster you have heard about or experienced. Use the conversation below as a model.
Sandy: Did you hear about the fog disaster in the USA last week
Millie: No. What happened
略
Sandy: The fog was so thick that drivers couldn‘t see more than a metre in front of them.
Millie: Oh, really
Sandy: Yes. Many cars hit each other. It was one of the largest traffic/'tr f k/ accidents in US history!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
长难句分析：这是一个复合句。主句主语是The fog ，was是系动词，so thick是表语，that drivers couldn’t see more than a metre in front of them 是结果状语从句。
Millie: Was anyone hurt
Sandy: Yes. Twelve people died and over 40 were hurt in the accident.
Millie: That’s terrible /'ter bl/!
~~
“超过”，相当于more than。
思考：What other natural disasters do you know
I also know about natural disasters such as tornadoes（龙卷风）, volcanic eruptions（火山爆发）, debris flows（泥石流）, landslides（山体滑坡） and so on.
TIP
We use “0h, really ” to express surprise, but pay attention to the tone, as the way we say it can give different meanings.
C In pairs, suggest a headline for each emergency or natural disaster you talked about in Part B.
