several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate siz关键帧并绘制甲骨文、金文、小籇“目〞子的轮廓，最后在第60帧插入空白关键帧，使用“文本工具〞输入楷体“目〞字，参考前面几种文字的轮廓调整该字的大小。执行“修改〞——“别离〞命令，将“目〞字中间的两横擦除。制作完成后“锁定〞该图层。
2〕制作“文字外部〞形状补间动画并添加形状提示点
首先分别在“文字外部〞、“文字内部〞图层的第12、32、52帧插入关键帧，在第80帧插入帧。在 “文字外部〞图层上，选择帧面板中第12帧至第20帧之间的任何一帧，更改帧“属性〞面板中的补间为“形状〞然后选中帧面板的第12帧，连续执行8次“修改〞——“形状〞——“添加形状提示〞命令，此时将出现的8个叠放在一起的提示点分别按顺序放于文字外部和内部的四角。最后选中帧面板的第20帧，将叠放的提示点参考第12帧的顺序，位置进行摆放。
3)制作“文字内部〞形状补间动画并添加形状提示点
2、学生听教师介绍并在书上对要点进行标记。
3、同组学生合作做任务，教师巡视并做个别指导。
教师展示形状补间动画实例，学生仔细观察都发生了哪些变化，那么什么是“形状补间〞动画？制作“形状补间〞动画的主要步骤是哪几步？
学生先看书自己尝试着做，如遇到问题同桌两个人商量，好多学生在做动画时容易无视把文字打散。
