2)特殊关键词
在常用关键词中，有两种关键词特别值得注意，他们分别是：
形容词的比较级和最高级：这类关键词的特点在于辨析度高，特有语法结构(-er, -est, more, most)使得他们在同意转换之后，还是非常容易辨认。
例5：Cambridge 5 Test 1 Section 4 Question 32
However, women are more prepared to …… about them.
读题：划名词women，划比较级more prepared
录音：A women, having fewer pretensions, is far more willing to learn.
解析：名词women完全匹配;形容词比较级more prepared转换为more willing, 由于有more的存在，使得转换容易辨认，匹配难度降低。
量词结构：量词在语法上类似于形容词，但篇幅比形容词更长;由于篇幅长的信息在听力中相对更容易捕捉，所以为了保持难度，题目中所有紧邻填空前的量词在录音中都会进行转换，因此：填空前量词必转换。
例6：Cambridge 5 Test 1 Section 4 Question 40
When investing in stocks and shares, it is suggested that women should put a high proportion of their savings in ……
读题：划名词stocks and shares，划填空前量词a high proportion of
录音：Many women are unwilling to invest in stocks and shares… It is usually suggested that at least 70% of a person’s saving should be in low-risk investment.
解析：名词stocks and shares完全匹配，帮助定位;
量词a high proportion of转换为篇幅更短的70%, 经过同意转换得到答案：low-risk investment.
3)关键词使用特殊情况
由以上可知，有助于匹配的关键词多处于填空之前，这也是考试的常见情况。但在少数情况下，关键词会处于填空之后，填空之前缺少或者没有关键词：
例7：Cambridge 5 Test 2 Section 4 Question 33
International teams work together.
…… is integrated with technical support.
