例二(原文介词为题目中介词的同义结构)
According to his biographer, James Boswell, Johnson’s principal achievement was to bring…………to the English language. As a reward for his hard work, he was granted a pension by the king. (剑5 Test 1 Reading Passage 1)
原文：It is the cornerstone of Standard English, an achievement which, in James Boswell’s words, ‘conferred stability on the language of his country’.
根据James Boswell、achievement等定位原文，再根据介词结构bring………to回原文找介词结构：conferred stability on…，由于两个介词结构属于同义结构，那么题目中介词to之前的答案应为原文介词on之前的部分：stability。
