课件中听力操作使用说明
许多下载我的课件的老师可能都遇到了同样的麻烦：听力操作比较麻烦。好多老师在给学生播放听力时，习惯于点击课件上的“小喇叭”图标，在使用我的课件时也用了同样的方法，结果却遇到了前所未有的麻烦，不知怎么办才好。下面我给大家讲解一下我的课件中的听力操作方法：
我的音频是嵌入式音频，所以老师们在使用我的课件的时候，不需要把课件和听力音频放到同一文件夹中，只需要课件就可以了。播放听力时，只需在其他任何地方按鼠标左键就可以了（不要点击小喇叭），就跟其他动画操作一样。用翻页笔的老师，只需要按翻页笔的“下一页”即可；如果想再听一遍，先按翻页笔的“上一页”，再按“下一页”就可以重复听。听完后如果按“下一页”，答案就会出现。
简单的一句话，我的课件中要播放听力，只需下翻页就可以。跟其他动画操作一样。(共58张PPT)
