sample dialogue
    (a: student a; b: student b)
a: are there any typhoons in the area where you live?
b: no, there aren't.
a: have you heard about it?
b: yes, i have. i saw a vcd about typhoon last year, and i learned something from it.
a: what is it like?
b: very terrible! when it happens, trees are pulled up and some old houses are
   destroyed.
a: is that so? i wish there were no typhoons in the world.
b: that's impossible. but when it comes, there will be rain with it.
a: how about hurricane and tornado?
b: there are many words for a violent tropical circular wind. a cyclone may be very large, bringing rain and great destruction. when it happens in the western atlantic ocean, it is called a hurricane, and the same tiling happening in tile western pacific or china sea is a typhoon. when shaped like a pipe and passing in a narrow path, it is a tornado if it goes over land and a waterspout if it goes over water.
a: i see. thank you very much for telling me so much.
b: not at all.
t: (show the screen.) have you met with one of such situations above? are you
    frightened?  have you heard anyone meet with that? describe how they behaved then. have a discussion with your partner and make up a dialogue. the useful expressions on the blackboard may be a help to you.
