例5 剑2 Test 4 Q 32
The main research method was
A interviews
B questionnaires
C observation
思路透析：审题时发现有main 这样一个比较关系提示词，做好听到比较关系的准备。
实际做题：可以用research来进行定位。
原文：For our research we depend mainly on talking to individuals， asking them questions rather than using written questionnaires.
解题：此题中 depend mainly on 与题目中的main形成呼应，从与个人谈话，问他们问题中不难看出是在进行interview，故答案为A。但值得注意的是rather than 这种表示对比的结构，它表达的意思是“而不是”的意思，通常是拿来排除某个选项的。
第三类：隐含比较
例6 剑3 Test 3 Q 37
Ostrich meat
A has more protein than beef
B Tastes nearly as good as beef
C is very filling
思路透析：虽然题干较短，而且没有比较指示词，但是AB两个选项都存在着比较，故此题依然以听比较关系为重点。
实际做题：原文：Ostrich meat is slightly higher in protein than beef， and much lower in fats and cholesterol. It tastes good too. A series of European taste tests found that 82% of people prefer ostrich to beef.
解题：其实答案A 很明显，几乎是原词重现。B错误的原因是大多数人们觉得鸵鸟肉比牛肉好吃，并不是一样好吃。要注意在比较时经常加入slightly 这样的副词来修饰比较级。
例7 剑4 Test 4 Q 14
On Travelite holidays， people holidaying alone pay
A the same as other clients
B only a little more than other clients
C extra only if they stay in a large room
思路透析：题目要求是说独自度假的人要付多少钱，从选项AB不难看出，此题要拿独自旅行的人和其他人做比较了。
