高二英語Unit10.Frightening nature

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? (show the form to the ss) 
(look at the form --- tropical cyclone naming conventions )
(then the teacher shows the map of the world, ask ss to tell the difference between typhoon and hurricane.)
 step 4  while reading
fast reading: skim the passage and try to get the general idea of the text. ( ss answer the main elements of a story: who, when, where, how)
careful reading: ss finish two tasks after reading.
 task1.scan the passage and find the answer to the following questions.
1. where did the ship meet the typhoon?
2. what was the weather at first?
3. why did the capital say that it looked as if a typhoon was coming on?
4. where were they when the full force of the hurricane struck the ship?
5. what should they do in such terrible weather?
6. what does the sentence “ another one like this, and that’s the last of her” mean?
7. why did the capital strike a match? what did he see?
 task2. try to explain the difficult sentence in bold in english.
1. it was fine, for there was no wind and the heat was close.
2. because he observed the barometer fell steadily and he knew that a terrible storm would come soon.
3. when the hurricane struck the ship with full force, they were all on the bridge.
4. they could only move the ship over the high sea and into the very eye of the wind.
5. it was the lowest reading he had ever seen in his life
  (if ss couldn’t understand the sentences, allow them to discuss with their partner.)
 deal with language points after that.
1. on board = in or on ( a ship, an aircraft or public vehicle)
 eg. 1) have the passengers gone on board yet?
       2) 一上船， 我總想吐。
    as soon as i’m on board i always feel sick.
