It is a picture of a farm. What is on the farm? There are some dogs, some cows, hills, and some trees and so on 。此时，利用图片讲解部分新单词。   （3）组织学生学习对话。教师也可以播放媒体动画，制造情景。内容详见本单元媒体素材中的动画。 口语训练建议   （1）本单元的口语训练应侧重于运用形容词和副词的比较级的相关句型介绍比较中美农场的异同和农村与城市的差异，教师组织学生就两个主题进行讨论，在讨论之前要求学生先要熟练掌握课文内容，否则学生说不出，将起不到预期的效果。   （2）教师也可以让学生将第14课的课文改编成一个对话，然后再练习。   例如：   Jone: Where do you live?   Ji Wei :I live on a farm. What about you?   JOne: I live on a farm too. What is your farm like?   Ji wei: The farm isn’t big. My parents grow rice and wheat. The sky is blue and the hill is green. Jone: Do you like it?   Ji Wei: Certainly. Can you tell me something about your farm?   Jone: On my farm, there is a lake. I always go fishing there in the summer and skating there in the winter. We always grow corn and wheat. Which do you like better, the country or the city?   Ji wei: I think the country is more beautiful than the city. In the city, I can’t hear the animals. In the country I can hear birds sing and sheep bleating.   Jone: I agree with you. 语音教学建议   oo组合在单词中的发音规律不明显，建议教师自己总结规律如：   A good cook looks book. 一个好厨师看书。这些词中的 oo组合都发短元音/u /的音，便于学生记忆。 词汇教学   人教社教学用书p35-36的词汇教学dingbat可以与该单元语法重点（比较级与最高级）相结合进行。如：   1）A dingbat is something that is more beautiful than all the paper flowers and dry flowers.(It is the real/ fresh flower.   2)A dingbat is something that goes fatster than the bike and the truck,but it is something that goes more slowly than the plane.(It is the car)   3)You like fresh and clean air, so a dingbat is something that you like better than the city.(It is the country)   4)A dingbat is something that is good at keeping the home, you like it better than the cat or the chicken.(It is the dog)
