PPT插入音乐背景

插入音乐背景 如何在ppt中插入音乐作为几张或整个幻灯片的背景音乐 PowerPoint 2003的功能已经相当丰富，但还没有一种直接为整个幻灯片添加背景音乐的功能。虽然我们可以通过依次点击“插入-影片和声音-文件中的声音”的方法来插入音乐(图1)，但是当演示到下一张幻灯片的时候音乐就会停止。因此要使整个幻灯片使用一个背景音乐似乎是不可能实现的事情。 但事实并非如此，下面我就将我在实际操作中所的在PowerPoint中实现插入背景音乐的两种方法和大家一起分享(本文以PowerPoint 2003为例，其它版本请参照操作)。 1.依次点击“插入-影片和声音-文件中的声音”(图1)，在出现的“插入声音”对话框中选中要作为背景音乐的文件，然后单击“确定”(图2)，在弹出的对话框中点击“自动”按钮插入音乐对象(图3)。 Tools and personnel required: tools: large drills, turban 12.5 bit, wrenches, wooden hammer.
