第一招：相关保留原则，当选项中有两项表达意思相近时，那么正确答案必在这两项之中！这时只需稍微听一听对话，即可知答案，如果出现了双重相关，便可直接确认正确选项，只需听完对话加之认证一下即可！
典型例题：
A) Visiting the Browning.
B) Writing a postcard.
C) Looking for a postcard.
D) Filling in a form.
例题分析：B、C两项均含有 a postcard ，B、D两项均含有写...之意，即B、C和B、D构成双重相关，即可得出B为正确选项！
本题听力原文：
M: What's the matter? You've been sitting there for ages, just staring into space.
W: I told the Browning I'd send them a postcard. Now I don't know what to say.
Q: What's the woman doing?

第二招：异项保留原则，当选项中出现有意思明显相反的两项时，那么正确答案必在此二项中出现！如果出现双重异项，那么即可判断出正确答案，异项保留原则在六级考试听力短对话中应用广泛！
典型例题：
A) She can’t finish her assignment, either.
B) She can’t afford a computer right now.
C) The man can use her computer.
D) The man should buy a computer right away.
例题分析：A、B异项，A项的意思是她现在有电脑，B项的意思则是她现在没有电脑。B、D异项，B是说女方无电脑，而D是说男方无电脑，男女也是一种反意关系。所以根据双重异项原则可确定正确答案为B项！
本题听力原文：
M: I'm frustrated. We're supposed to do our assignment on the computer, but I have difficulty getting access to the computers in the library.
W: I understand the way you feel. I'm looking forward to the day when I can afford to get my own.
Q: What does the woman mean?
