雅思阅读同义替换(四)主动语态和被动语态的转化
1. C5T1P1 As a reward for his hard work, he was granted a _____ by the king.
解析：根据the king定位到文中最后一段The Dictionary, together with his other writing, made Johnson famous and so well esteemed that his friends were able to prevail upon King George III to offer him a pension. 被动语态的基本结构：主语+be+动词过去分词+by, 与文中主动语态对应上，答案为pension“养老金，退休金”。
2. C7T1P1 Radar is an inaccurate term when referring to bats because _____ are not used in their navigation system.
解析：根据上下文定位到文中It is technically incorrect to talk about bat 'radar', since they do not use radio waves. 很显然被动语态的主语在文中为主动语态的宾语，答案为radio waves。
