第一类：直接比较
例1 剑7 Test 2 Q 34
A German study showed there was greater ‘mixed handedness’ in musicians who
A started playing instruments in early youth
B play a string instrument such as the violin
C practice a great deal on their instrument
思路透析：题干中包括greater这个明显的比较级，要提醒考生们注意的是，在实际的听力中，比较级的用词可以发生同义转换，但是这种比较关系的表达一定在听力文本中是存在的，所以要特别关注在听力内容中比较的表达方式，答案就在其中。这与填空题是一致的，在填空题中如若发现比较表达方式，那我们可以把它当特殊关键词来对待，耐心等待听力素材中的比较表达后即可得到答案。
实际做题：在实际做题中，当听到Germany study 时确定做题位置。
原文：keyboard players had high levels of mixed handedness, whereas string players like violinists strongly favored one hand. Also those who started younger were more mixed handed。
解题：从原文中我们不难看出，小饥码提琴演奏者的用手习惯比较倾向于某一侧。所以排除B。紧接着出现的整句话里出现了两处比较级，more mixed handed 与greater mixed handedness 形成同义转换，younger 与选项A中的early youth 对应，所以正确答案为A。
第二类：间接比较
例2 剑7 Test 1 Q 12
The company has most camping sites in
A France
B Italy
C Switzerland
思路透析：题干首姿中包含有most sites 这个最高级的表达方式，故做好准备去听比较关系同义转换即可得到答案。
实际做题：当听到300 sites 以及Italy 等信息后可以定位做题位置
原文：In Italy we now have some 64 sites that we either own, or have exclusive use of . France is where we have the majority of sites, and we currently have a project to expand into Switzerland。
解题：不难发现majority 和most 之间存在同义转换，故答案为A。
第三类：隐含比较
例3 剑2 Test 3 Q 31
The driest continent is
A Australia
B Africa
C Antarctica
思路透析：题干中有driest 这个最高级，要高度注意比较关系的同义转换。烂芹哪
实际做题：听到Australia 后确定做题位置。
原文：As I have said, Australia is a dry continent, second only to Antarctica in its lack of rainfall。
解题：不难发现答案是C，但值得我们注意的是，second only to 是一种特殊的比较表达方式。
