a. 通過同學(xué)們喜聞樂見又非常熟悉的兩個(gè)卡通人物jerry，tom和alice的對(duì)話引出本課重點(diǎn)句型和詞匯學(xué)習(xí)。
（早上，tom 和 jerry兩人都背著小書包，走進(jìn)一所小學(xué)）

(下課的時(shí)候tom 和jerry兩人在校園的操場(chǎng)上遇見了他們的校友a(bǔ)lice.alice正在欣賞一張美麗的照片)

jerry: wow! what a nice picture! may i have a look?
alice: sure, here you are.
tom&jerry：who are they?

b. 教師帶領(lǐng)學(xué)生進(jìn)行本課重點(diǎn)句型may i have a look? sure, here you are. /who are they? they are my...及短語my classmates, my schoolmates, my friends, a nice picture.的學(xué)習(xí)：
教師在整理自己的講桌，假裝不經(jīng)意從書中掉下來一張自己兒時(shí)的照片，然后說道：oh, boys and girls! what a nice picture! look! who are they?can you guess?教師拿著照片在教師轉(zhuǎn)一周讓同學(xué)們猜測(cè)欣賞，然后將照片放在幻燈片上放大，全班一起欣賞。此時(shí)，教師可鼓勵(lì)學(xué)生用自己的語言進(jìn)行發(fā)問，對(duì)表達(dá)較好的學(xué)生要提出表揚(yáng)哦。在這里教師要給學(xué)生說明：picture可以指圖畫，也可以指照片。借助一些漂亮的圖片，可以鼓勵(lì)學(xué)生用上一節(jié)課所學(xué)過的感嘆句進(jìn)行語言輸出表達(dá)訓(xùn)練：how nice the picture is! 然后與此同時(shí)教師引出今天要學(xué)的另一個(gè)由what引導(dǎo)的感嘆句句型what a nice picture!讓學(xué)生通過比較了解到how后面跟形容詞，而what引導(dǎo)的感嘆句后面跟名詞短語。教師應(yīng)舉出大量的例子讓學(xué)生在對(duì)比中進(jìn)行學(xué)習(xí)和掌握，還可以讓學(xué)生將兩個(gè)句子進(jìn)行轉(zhuǎn)換訓(xùn)練。
c. 在感嘆句基本掌握的情況下，教師不斷的重復(fù)who are they?do you know? can you guess?然后引出they are my classmates, and this girl is my schoolmate, they all are my friends.等本課重點(diǎn)句型。在這里教師要給學(xué)生講清楚：
一：classmate, schoolmate，friend 三詞的區(qū)別。在這三個(gè)詞中，classmate, schoolmate 是合成詞，分別是由class和mate, school和mate合成的。前者是同班同學(xué)，后者是校友，其復(fù)數(shù)形式為classmates和schoolmates. 而friend則為朋友的意思。
二：who are they? 表示 “他們是誰？”為復(fù)數(shù)形式，其單數(shù)表達(dá)為： who is she/he? 回答用she/he is…
接下來教師向?qū)W生發(fā)問：do you want to have a look?然后引導(dǎo)學(xué)生學(xué)習(xí)表達(dá)may i have a look?句型，在此希望教師能給學(xué)生說明，想要征求他人同意的時(shí)候可用may i…?這個(gè)句型，回答可用sure!
