2. D　本句为过渡句。空格前作者用直接引语的方式描述了"教舞蹈简直太美妙了"。空格后句子中出现的代词them指代的就是Bridges所教的学生。D项中的students和them相对应,所以答案为D项。即我的那些年龄大的学生说舞蹈让他们感觉自己年轻。

3.A　本句为主旨句。空格位于段首。后面以一对年轻夫妻为例说明了跳舞给他们带来的好处。由此推断出本段是描述跳舞会给一个人的情绪带来巨大的影响,这就是人们喜欢跳舞的原因。这与A项(那么,我们为什么要跳舞呢?)相符。

4.F　本句为细节句。空格前描述这对夫妻刚来到舞蹈班时情绪低落,当他们离开的时候脸上露出了微笑。这都是舞蹈给他们的情绪带来的变化。这与F项(舞蹈好像彻底改变了他们的情绪。)相符。

5.E　本句为过渡句。空格前描述这么多年来Hillier想跳得越来越好。空格后描述Hillier发现自己就是停不下来,跳舞让Hillier知道自己还活着。作为前后过渡的空格处应该与Hillier一直不停地跳舞相关,这与E项(即使当我非常累的时候我还在练习跳舞。)相符。
