录音：Now， I need to tell you that this is a very popular course and it's essential that you book well ahead of time. In fact， the Course Convenor tells me that there are only five places left.

　　解析：通过I need to tell you that这样一个强调句型来定位题目中的students should。随后，通过对book well ahead of time的同意转换(reserve in advance)，选出C。

　　后面出现干扰内容：the Course Convenor tells only five places left，视线移到B，但根据B里的动词contact，可判断B内容与录音不符(录音说Course Convenor告诉说话者只有5个位置留下来，其实还是要提前预订的意思，而B说的是让学生自己去联系Course Convenor)，所以B是干扰项。

　　因此，选项中关键词划取的快速原则是：名词-形容词/副词-动词。

　　至此，很明晰的一点是：对于雅思听力，读题，或者更正确的说是有针对性的读题，非常的重要！所有的努力，所有的准备工作，都是为了在听题时能更有效的进行同意转换，找到正确答案。

　　如果说听题是战场杀敌，读题就是战前侦查，侦查到位，知己知彼，侦查不到位，死都不知道怎么死的。读题做到位了，听题也就自然而然了。

　　步骤如下：

　　1.Locating：locate where the question is.

　　2.Judging：judge whether every choice is right or wrong.

　　简单的说就是：定位-判断，两步走。同时，在判断当中一定要牢记前面说过的两个特点：Indirect answer和Trap.

　　3.选择题型中的预测 Prediction(预测)是听力两个基本解题方法中的一个(另一个就是关键词)，主要运用于填空题型，但在选择题型中偶尔可以运用。

　　填空题型的预测主要在于观察选项组合，有一种组合是非常容易预测的，即干扰性组合：三个选项中有两个有明显的互相干扰作用，则另一个选项可以暂时排除。

　　例7：Cambridge 5 Test 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.

　　预测：BC选项存在明显互相干扰作用，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：One or two of you ask earlier about your level of spoken English， obviously most of you have already achieved a lot， I wish I could speak your language half as well. 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.

　　解析：通过最后一句Some extra practice before you arrive is worth more than， for example， private lessons afterwards，可判断正确答案为C，录音通篇未提A，这是因为这样的选项组合，出题意图就在于用BC来进行干扰，如果答案用A则不能利用到BC的干扰作用，无法达到出题目的。

　　选择题的难度较大加上目前考试过程中选择题所战友的比例也有适当的增加，希望以上的分析能够帮助考生们解答选择题，得到理想的听力分数！
