Lets have a look. While watching them, think about “ 1)Where are they? 2)What are they?”老师用PPT播放农场里的动物、水果、蔬菜等图片，让学生欣赏。教学目的：通过农场图片让学生了解目标与内容，吸引学生，引起学生的兴趣。二、Review the words1.T: Boys and girls, what do you see in the pictures? And where are they? Ss: We see some.They are at the farm. T: Yes, there are many animals, vegetables, and fruits at the farm. 老师在黑板上画出思维导图。What animals are at the farm? What vegetables are at the farm? What fruits are at the farm?老师分别提问这三个问题，并把单词板书到思维导图里。2.Look at the PPT, and read the words in groups, please.教学目的：通过提问的方式，激活学生已有知识；老师通过画思维导图，帮助学生把知识系统化，学生把单词记得更牢固，更有意义。三、Review the sentences.1. Brain storm: T: Lets look, and say sentences. 闪图，学生说句子。Eg:出现一只山羊，Ss: Its a goat. 出现多只绵羊，Ss: They are sheep.教学目标：利用头脑风暴游戏，让学生说句子，从视觉上、口头上判别和区分单、复数句型：Its a.Theyre.四、复习名词的复数形式1. T: This is a picture of a farm(图片里有鹅、猪、猫、兔子、狗，他们都藏在草和树丛里，只露出身体的部分).What do you see in the picture? Ss: I see some cats in the picture. T: How many cats are there? Ss count the cats and answer: There are five.老师用这样的方法，把图片里的动物问一遍。2. 在图片下方呈现短语six rabbits ( ) eight rabbits( ) four cats ( ) five cats( ) two geese ( ) three geese ( ) two pigs ( ) five pigs ( )，T：boys and girls, can you according to the picture, choose the right answers?学生根据图片选择正确的答案，接着老师引导学生说出这些都是复数形式。3.There are some words here, can you change them into complex form.学生独立完成练习。4.Check the answers，投影某一个学生的答案，与学生一起检查。5. Boys and girls, 你懂的单数变为复数的方法了吗？有多少种方法，请同学们在小组里讨论，然后总结出答案。6.老师提问，然后用序号1.2.3.4板书答案，老师要把“不变：sheep”列为1），这样，学生才能首先把sheep的复数形式记牢。教学目标：先通过谈论农场里的动物，引出复数，再让学生通过自己做题，讨论，得出名词单数变复数的方法，这种通过自己学习得出结论的探究性学习方法，更能体现出学生学习的过程，反而更能够让学生掌握知识。五、综合能力训练1. Lets play a guessing game: I am at the farm. I see some/a /an.学生根据老师给出的动物、蔬菜、水果类别和单、复数信息用Is it a?/Are they?提问老师. Eg: T: I am at the farm. I see an animal. Ss: Is it a goat? 老师根据图片用肯定句或否定句来回答。教学目标：这个活动需要学生听懂老师的信息，然后自己判断应该用哪个问题来询问，训练到学生的听力和口头表达能力。2. T: Listen! Where?让学生听声音，猜猜是在哪里3. T: Yes. Its a farm. Whats at the farm? Lets have a look. 老师用PPT呈现两张图片，要求学生根据给出的信息把问答句补充完整，再过渡到独立写出完整的问答句。Eg: A: What is _? A: What are _? B: Its _. B: They _. A: _? A:_?B: _. B:_.4. Lets check the answers.投影某个同学的答案，与大家一起批改。教学目的：通过让学生听声音创设情境farm，利用农场里的东西来让学生补全句子到写完整的句子，从易到难，从笔头上落实学生写的能力，并且通过学生自己写句子来区别单复数句型，学生印象更深刻，记得更牢固。5. T: Mikes aunt has a farm. Whats at the farm? Listen, and choose which farm is belong to Mikes aunt.同时给出两张农场的图片，图片的动物数量有些是相同的，有些是不一样的，有复数，有单数，让学生听篇章，然后选出正确的图片。教学目的：同时给出的两张农场图片，存在着信息沟，那么，学生首先就要会读图，找出存在的差异，然后细心地听录音，根据录音内容找到图片。这样可以训练到学生细心观察图片和听的能力。通过听篇章选图，为学生建立系统的信息，为下一步的写做好准备。6. Look! This is a farm, too. Its big. There are also many things on the farm. What are
