三、課堂教學設計
1．複習 值日生報告。
2．教師用如下語言引出本課要學的內容：
T: Today I'm going to do some shopping after school. What am I going to buy? Now look at these shoes of mine.（出示事先準備好的舊鞋。如果穿在腳上，可增加表演效果。）They are too old. Or we may say they are WORN OUT. So I want a new PAIR OF SHOES. What SIZE do I need? Oh, I know, I need size eight.
通過以上演示介紹生詞以後，反覆領讀生詞。
3．準備聽課文第1部分錄音，教師用投影儀打出聽前提問 (Pre-listening questions): 1) What's wrong with the man's shoes? 2) What does the woman ask him to do?
聽錄音一至兩遍，學生回答上述問題。
教師再用投影儀打出課文第2部分的聽前提問 (pre-listening questions): 1) What size of the shoes does the man want? 2) How much do the shoes cost?
聽這部分錄音兩遍，學生回答上述問題。
再聽錄音，學生跟讀一至兩遍。
4．學生兩人一組，練習表演這段對話，請幾組同學到前面演示。
要求學生利用課本上提供的替換練習，編寫一、兩個購物的小對話，教師予以講評。
5．請學生挑出本課中出現的有關購物用語，並抄寫一遍。
6．佈置作業
1）練習朗讀本課對話，抄寫生詞及有關購物用語；2）書面完成練習冊習題。
四、難點講解
1．My shoes are worn out. 我的鞋穿壞了。
wear out是“穿破、穿壞”的意思。
在這個句子中，包含有一個系表結構。
被動結構的形式是助動詞be+過去分詞。但並非所有的be+過去分詞都是被動結構。由於過去分詞具有形容詞的特點，某些過去分詞可以用作句子中的表語。所以be+過去分詞可能是連繫動詞be+表語結構，而不是被動語態。系表結構與被動語態的區別是：被動語態表示以主語為承受者的動作；而系表結構則表示主語的特點或所處的狀態。請比較以下例句：
The window was broken by a boy just now. 窗户剛才被一男孩打破了。（被動語態）
The window is broken. 窗子是破的。（系表結構）
Everything was done by his parents. 一切都是由他父母乾的。（被動語態）
Everything was done. 一切就緒。（系表結構）
2．I'm afraid we haven't got any black shoes in than size at the moment. But we've got some brown ones. 恐怕我們眼下還沒有這種尺寸的黑鞋，但我們有些棕色的。
ones是代詞one的複數形式。在句中指上文提到過的名詞shoes。

三、課堂教學設計
1．複習 值日生報告。
2．教師用以下語言引導出本課生詞：
T: Yesterday I went to do some shopping. I wanted to buy a pair of shoes because my shoes were worn out. First I went to a small shop, but they didn't have any shoes. They SOLD OUT all the shoes. Then I went to another shop. But the shoes there were EITHER too big OR too small (藉助手勢加以説明). The shopkeeper said PERHAPS (or: maybe) they would have more shoes soon. I'll go there again and have a look.
反覆領讀生詞，直到學生初步掌握為止。
3．佈置學生閲讀課文。給學生六分半鐘時間（本課計約264個詞），允許學生查閲其它個別生詞。教師用投影儀打出讀前提問 (Pre-reading questions): 1) What was the boy going to do a week later? 2) What did he decide to buy at last?
規定時限過後，學生回答上述問題。

5．做練習冊習題1，先要求學生予以口頭回答，再佈置為書面家庭作業。
6．扼要解釋課文難句（見難點講解）和過去完成時的構成及用法。
7．佈置作業
1）練習朗讀本課課文，抄寫生詞；2）準備複述課文； 3）書面完成練習冊習題。
四、難點講解
1．The shop was quite new, for it had opened only the week before. 商店很新，因為它上一週剛剛開張。
for是連詞，表示：因為。
2．They were either too big or too small. 它們（指鞋）要麼太大，要麼太小。
either…or…意思是：或者……或者。這是一組表示選擇的並列連詞。當連接兩個並列的主語時，動詞與最接近的主語保持數的一致。例如：
Either you or I must go. 你和我總要有一個人去。
You can either do it yourself, of you can ask someone else to do it. 要麼你自己做，要麼你找人來做。
Either the teachers or the head master is in the office. 或是老師們，或是校長在辦公室。
3．That's cheap. I'll have it, please. 這東西便宜，我買下了。
That's much too expensive. I don't think I'll take it. 這東西太貴了，我不想買。
注意，兩句中動詞have和take均表示“買下”的意思，而不用“buy”這個詞。
much可以和too連用，修飾名詞或形容詞，但位置不同：修飾名詞時，用too much；修飾形容詞時，用much too。例如：
The doctor asked the fat lady not to eat too much food every day. 醫生告誡那個胖女士每天不要吃太多的食物。
We can't go out. It's much too cold today! 我們不能出去，今天太冷了！

規定時限過後，學生回答上述問題及閲讀提示中的提問，教師予以評判。

7．佈置作業

四、難點講解
1．They were so pleased to see each other that they forgot everything else. 他們又見面了，高興得把其它的事都忘了。
句中so…that引導的是表示結果的狀語從句。so既可以修飾形容詞，也可以修飾副詞。例如：The coat was so expensive that he didn't buy it. 這件外衣太貴了，他沒有買。
so…that的中文意思是：如此……以致……，但通常都不譯出。例如本課第2部分的三個句子可以分別譯為：
1）這套衣服太貴了，他買不了。
2）這件夾克很便宜，他決定買下了。
3）他的鞋太髒了，必須涮洗。
2．They talked on and on very happily. 他們都很高興，不停地聊起來。
句中 on and on是副詞短語，表示“不停地做某事”。
