48課 Did you want to tell me something
    Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth was full of cotton wool. He knew I collected match boxes and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cotton wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.
    精講筆記：
    1. Dentists always ask questions when it is impossible for you to answer.
    牙科醫(yī)生們總是在你無法作出回答的時候向你提出問題。
    真題測試 測試語言點：狀語從句
    I was halfway back to the cottage where my mother lived___Susan caught up with me. (2001年1月 CET4,第68題)
    A. though B. until C. when D. while
    答案：選C
    分析：本題考查狀語從句的用法。根據(jù)句意，A和B兩項不合適；D選項多用在表示持續(xù)性的動作或狀態(tài)的句子中；C項when,既可以和延續(xù)性動詞連用，也可以和瞬間性動詞連用，既可以表示從句和主句動作同時發(fā)生，也可表示主句動作在從句之后或之前發(fā)生所以入選。
    翻譯：蘇珊追上我的肘候，我正在回我媽媽住的小屋的途中。
    2. My dentist had just pulled out one of my teeth and had told me to rest for a while.
    我的牙科醫(yī)生剛剛給我拔掉了一顆牙，叫我休息一會兒。
    真題測試 測試語言點：just的位置與過去完成時
    We___ our breakfast when an old man came to the door. (1990年1月CET-4，第53題)
    A. just have had B. have just had C. just had D. had just had
    答案：選D
    分析：just一詞的位置一般在助動詞之后，A和C明顯錯誤。B為現(xiàn)在完成時與時間狀語從句的過去時不符合，因此D選項是正確答案。
    翻譯：當(dāng)一個老人進門的時候，我們剛好吃完早飯。
    3. I tried to say something, but my mouth was full of cotton wool.
    我想說點什么，但我嘴里塞滿了藥棉。
