而正确答案B中的aid被替换成了help.同时，对于干扰项A中的weaknesses这个单词，答案中也出现了一些相关的可互相替换的信息，如weaker side，但A选项的整体意思和听力原文中的表述不符，这也就是A选项的干扰点所在。
如《剑7》Test2 Section4中的Question31
题目
31 Anita first felt the Matthews article was of value when she realized
A how it would help her difficulties with left-handedness
B the relevance of connections he made with music
C the impressive size of his research project
原文
What Anita soon became struck by was the sheer volume of both observation and investigation he had done in many different sports.
听力原文中，the impressive size被替换成了the sheer volume，而关键词research project也被替换成了observation and investigation.
如《剑6》Test2 Section2中的Question14
14 The price of a first class ticket includes………………….
听力原文中，price被替换成了cost，而主动语态includes也被替换成了被动语态are included.
由上述例子可以看出，无论是填空题还是选择题，都会或多或少地遇到同义转换。下面，同样以真题为例，详细讲解贯穿雅思听力各个题型中“同义转换”主要的表现形式。
1、语法角度
A、 词性的转换
词性的转换主要是几种常见和常用的词性之间的转换，如名词、动词、形容词和副词等。
如《剑7》Test2 Section3中的Question25
题目
25、According to Dr. Merrywhether, Antarctica is very cold because
A of the shape of the continent
B it is surrounded by a frozen sea
C it is an extremely dry continent
原文
Antarctica is a land mass shaped like a dome, with the result that the winds blow down the slopes at speeds of up to 150km an hour and that’s what makes it so cold.
原文中出现的是……is a land mass shaped like a dome.正确答案在选项中出现的是名词形式shape，而在原文中却以动词的形式shaped出现。所以同学们在准备雅思听力词汇的时候，一定要注意每个单词的各种词性都掌握到位。
