　　19. 2014年6月英语六级听力短文解析：本题无法直接得出答案。第3、4句话说， What makes monarch butterflies particularly interesting is they migrate, all the way to California or Mexico in back. They are thought to be the only insect that does this. 第4句中的 the only insect that does this 就是本题题干的出处，而 this 指的是上文提到的他们迁徙的方式。由此得知，令monarch butterflies独一无二的是它们的迁徙方式。对应选项C: They are the only insect that migrates along fixed routes. Fixed routes表示固定路线，是对原文 all the way to California or Mexico in back 的概括性改写。

　　20. 2014年6月英语六级听力短文解析：本题来自文章中间。 Once in Mexico, they establish themselves in one of about 15 sizes in the mountain forth. 所谓的establish oneself in some place就表示在某处安家。对应选项D: In a Mexican mountain forest.
