15张左右的PPT自我介绍

你可以先介绍自己在哪个高中上过学，来自哪个地方（2-3页）然后介绍自己性格爱好，有啥特长没有，或是特别喜欢什么.用个几页，最好有点照片，比如你爱旅游就弄点风景照，或是喜欢狗弄上狗狗照片，或是你特别喜欢哪个明星都可以。感觉15页也不算多
最重要的是配上好看的背景图和音乐，这个你自己搜搜吧网上很多的

我要做泰迪狗的PPT，请问做关于它的哪些内容比较好？

简介（脾气，性格，毛发）、起源、外形特征，如何培养感情，这几点就够了，具体看百度百科，
梳毛打理，饮食什么的就不用讲了，或者几句概括一下

狗的ppt应怎样做

首先介绍狗的总体概况（简要摘几句就可以了）
然后可以从他们的分来来看
同时要插上图片
然后可以介绍狗的职业，也就是用途，比如你说的那些
时尚点的可以介绍几个狗的电影比如小Q之类的呵呵
最后以狗狗图片的欣赏结束好了~
要是太少
可以介绍一点特殊种类的狗狗

怎么样做关于狗的ppt

首先介绍狗狗的类型，然后再挑选几种来展开描述，每种都配几张图片，或者链接视频之类的，最后可以描述你最喜欢哪种。具体方法如下:
用狗狗图片做背景:右击空白的幻灯片，选择背景格式，然后选择背景填充，文件，然后就去挑选自己下载好的图片，然后点打开就可以了
插入音频:工具栏上面的音频，点从已有文件中插入，然后就可以插入自己喜欢的音乐。插入后还可以剪切音频，工具栏上面会出现剪切的。

我要做一个介绍狗狗的PPT，求推荐适合的背景音乐

'龙猫'的主题曲，个人很喜欢，推荐给你~
