3. 听到题干的路标词后，抓住句子的核心词，快速与选项进行对照。如果选项中的核心词汇(即上一点提到的细节词汇)在原文没有对应，此选项往往为干扰项;
4. 有些选项构成明显的对比，往往可以通过它们之间的差异，缩小听音范围。
例题解析3: (Cambridge 5Test 3 Section 2 Question 20)
With regard to their English, the speaker advises that students to
A. tell their lecturers if they have problems understanding.
B. have private English lessons when they arrive.
C. practice their spoken English before they arrive.
解析：B、C选项存在明显对比，一个是到英国后加强英语，一个是来英国前加强英语;关键词分别划在when和before, 来进行区分，同时可以先排除A。
(录音：Having said that though, I’m afraid the lecturers will make little or no allowance for the presence of non-native speakers in the audience, so anything you can do to improve your spoken English, even beyond the pretty high level most of you have already reached will make your stay with us that bit more fun for you. Some extra practice before you arrive is worth more than, for example, private lessons afterwards when you won’t really have time.)
二、多选题：
雅思听力多选题特点：
1. 选项通常较长，需要考生快速、准确的阅读能力;
2. 正确答案的数量在题目中有规定，考生要注意题干要求。
雅思听力多选题解题思路：
1. 分析选项的方法与单选题相同;
2. 比较选项，找出结构相似细节不同的选项，这样的选项中往往会有一个是答案;
3. 选项较简单的，录音和选项会有同义替换，不能按照所听即所得的原则选择。
