step 2  lead in
t: in the last few periods, we deal with a letter about volcano. it is a terrible nature disaster. this summer our hometown also experience a terrible disaster----- typhoon, one called yunan. it caused great damage, isn’t it? can you describe it? ( ss: …. )
t: if it happens in usa, what do people call? (a hurricane )
in fact, a typhoon is the same thing as a hurricane except the place where they form. before we deal with the detailed information, let’s watch a short video to experience the story wind again and here are two questions for you.
what does the hurricane bring in?
how long will it usually last?
(ss watch the video and give the answers. if it is necessary, play it twice.)
step 3 pre-reading
t: we know typhoons can cause great damage or even deaths. in order to reduce the loss and protect ourselves, we have to learn more about it. then what else do you know about the typhoon? tell us what you know, please! first talk with your partner and then tell the whole class what you have discussed.
( pair work for two minutes and then one or two ss report )
(this activity is to motivate the ss to talk in english and cooperate well with each other.)
 ( then the teacher introduce the background information )
t: now, let’s look at the diagram. we’ll know what is typhoon. typhoon is a kind of tropical cyclone. it’s the atmospheric whirlpool formed on the warm tropical ocean and the area of low pressure. winds are produced because the pressure of the air is different in different places. air flows from a region of high pressure to a region of low pressure, causing a wind. the low pressure center is the eye of the storm. and tropical cyclone is the general name of tropical depression, tropical storm, severe tropical storm and typhoon or hurricane. in usa, people don’t use the name of severe tropical storm and typhoon. instead, people use the name---- hurricane. all over the world, people name these tropical cyclones according to their strongest speed of wind. can you guess how fast a typhoon can move?
