第一招：相關保留原則
當選項中有兩項表達意思相近時，那麼正確答案必在這兩項之中!這時只需稍微聽一聽對話，即可知答案，如果出現了雙重相關，便可直接確認正確選項，只需聽完對話加之認證一下即可!
典型例題： 19xx年12月第4題
4. A) Visiting the Browning.
B) Writing a postcard.
C) Looking for a postcard.
D) Filling in a form.
例題分析：B、C兩項均含有 a poscard ，B、D兩項均含有寫...之意，即B、C和B、D構成雙重相關，即可得出B爲正確選項!
4. M: Whats the matter? Youve been sitting there for ages, just staring into space.
