第二課時一、課時內容A.Lets talk A. Lets play二、課時分析本課時是義務教育靈通版（pep）小學英語教科書四年級下冊的第四單元第二課時，本課時繼續圍繞“參觀農場”這個話題展開內容，與第一課時緊密相連，包括 A.Lets talk A. Lets play 兩個板塊。本課時的A Lets talk .部分通過Mike 與Sarah 參加農場并與農場主人對話的情景讓學生感知句型：Are these carrots? Yes, they are. No, they arent. 以及What are these? Theyre tomatoes.的語義及語用情景。A Lets play 部分則是用來操練A Lets talk板塊的核心句型。本課時核心句型是涉及名詞復數形式的特殊疑問句和一般疑問句，這一知識點在四年級上冊第四單元的B Lets talk 出現過一次，本冊學生用書的前三單元均未有涉及。教師可創設適當的語境讓學生充分的感受并理解名詞單、復數的意義以及相應句型變化，并能在情景中正確運用和表達。三、課時目標1. 能夠在情景中運用句型：Are these ? Yes, they are. No, they arent. 以及What are these?

Yes, they are. No, they arent. 以及What are these? Theyre .并能做出正確的回答。2. 課時難點Are these 后面跟的是名詞的復數形式。五、教學準備1. 學生自制單詞卡片2. 教學掛圖及配套PPT3. 錄音機及配套磁帶4. 西紅柿、豆角、土豆、和 胡蘿卜的實物5. 一個箱子六、教學過程Step 1 Warm upT: Good morning, everyone.Ss: Good morning, teacher.T: Nice to see you again.Ss: Nice to see you, too.設計意圖：通過師生問候的形式，讓學生在課堂上動起來，即鍛煉了學生的交流能力，又活躍了課堂。Step 2 Lead in活動：夸一夸菜園的蔬菜。活動方案：老師課件展示一個豐收的菜園的景象，要求學生用贊嘆的口氣夸一夸這些蔬菜。如：S1： Look at the green beans.

Lets play活動：猜詞卡游戲活動方案： 將全班學生分成三人一組利用手中的詞卡做游戲。第一位同學拿出一張詞卡背對同學們問：What are these? 另一位同學就來用一般疑問句來反問，如果不正確就由第三位同學來反問。直到猜到為止。如：S1：What are these? S2：Are they tomatoes?S1: No.S3: Are they tomatoes?S1: Yes, they are.設計意圖：通過本活動操練了A.Lets talk中的核心句型，活躍了課堂，使學生能夠在語境中熟練地運用句型。Step 4 Practice 活動：摸一摸 ，猜一猜，說一說 活動方案：老師把一些水果放到課前準備的箱子里，老師叫一名自告奮勇的學生到臺前摸一摸，然后由全班同學發問：What are these? 這位同學根據自己的感覺回答：They are .全班同學根據這位同學回答用Are they ? 提問。在同學們發問的時候，把水果拿出來，如果說對了大家就一起說：Yes, they are. 如果說錯了，同學們搖頭不語。如： S全： What are these?S指名：They are apples.S全： Are they apples?S全： Yes, they are. 設計意圖：創設情境，使學生進一步運用、鞏固A.Lets talk中的核心句型，。Step 5 Summary T：Boys and girls, Lets look back this class.
