第一課時

   b: it’s cool. we can go to climb the mountain.
   a: how is the weather in winter?
   b: it is very cold. but we can make snowmen .
  ask some pairs of students to make up new dialogues by using the sentence structures above.

step 2. presentation (teaching new words 15min)
  1) draw some clouds on the blackboard, and say “ it’s a cloudy day today, there are many clouds in the sky. so it is very dark , after without clouds, it will become bright. guess the meaning of cloudy and bright.”
  2) draw a snowman on the blackboard, and say “only on a snowy day ,we can make snowmen ,but on that day it is very cold, it is quite cold, then can you guess what snowy and quite mean ?”
  3) use a picture which describes a girl is watering the trees in the sun , and say “do you think it is very hot on a  sunny day? in summer, almost everyday is sunny day, everywhere is very dry, so we must water the trees to survive them. guess the meaning of sunny and dry.”
  4) let the students see a video, two cars are crashed to each other on a foggy day, because the drivers can not see each other clearly. and say “on a foggy day, we can not see others far away from us, so it is very dangerous for drivers to drive the cars. guess the meaning of foggy”.
  5) use a flash on which the wind blows, and the leaves fall down from the trees, say” on a windy day, because the wind blows, the leaves fall down. guess the meaning of windy”.
  6) take a thermometer to the classroom ,point it and say “today’s temperature is 20 degree centigree. in winter, the temperature is often below 0 degree centigree. then  who can tell me what temperature means?”
  all those above can ask different groups to answer .the group who guess right will get some presents from the teacher.
