語言應用
隨著網絡時代的到來，“網上購物”以其便利優勢成為當今的消費方式之一。教師可以讓學生搞一個調查。向他們周圍的人了解網上購物情況，對網上購物的態度等。幫助學生在理解課文的基礎上聯系實際進行知識遷移，用所學語言解決實際問題。例如：
s1: i'd like to know something about shopping online.
s2: what would you like to know?
s1: have you ever bought anything online?
s2: never.
s1: why?
s2: the disadvantage is that i can't see the goods before i buy them. and i can't touch the goods and i can't talk to the salespersons. in a word, i feel uncomfortable.
s1: (to s3) do you like shopping online?
s3: yes.
s1: why?
s3: because it's interesting. it saves a lot of time and i needn't leave home to buy things. i just click the mouse to order what i like.
s1: have you ever done shopping online?
s3: yes. i bought a car online last year. it was very nice. i had just chosen the type, the brand i like. then they sent it to my home. i was glad that i had just got what i wanted in half an hour.
that's great.
(二)教學過去完成時
　　教學時態的最好形式之一是在一定的語境中通過與其他時態的比較來加深學生對這個時態的理解，這樣學生首先有個感性認識，然后經過歸納總結，這種感性認識會逐步上升為理性認識。本單元第一次教學過去完成時，前面已教學了現在完成時態和一般過去時態。
　　教師首先讓學生學習第54課課文，讓他們找出含有過去完成時的句子。如：
　　1) she had searched the internet for two hours when she found an ad for the canon digital camera.
　　2) after she had found more information,. . .
　　3) after he had checked out all the information about different kinds of cameras, he believed his daughter had made a good decision.
    4) a week later miyoko received the camera she had ordered.
　　讓學生觀察過去完成時與現在完成時在構成上的差異，如had或have+過去分詞，時間狀語的不同。
　　再要求學生比較過去完成時與一般過去時的不同，并且畫出時間線，以比較兩種時態。
 
　　教師此時再讓學生思考已找出的句子的前后語境，尤其要區分一般過去時與過去完成時的不同用法。本單元出現的過去完成時態，學生只要掌握過去完成時在什么情況下使用，表達什么時間意義即可，因為下一單元還會繼續學習這個時態。我們在本單元可以要求學生做相應的句型轉換練習，其中包括陳述句，疑問句及其肯定與否定回答。
