简述幼儿绘画能力发展的阶段。
(1)涂鸦阶段。儿童在1岁半左右，甚至更早一些的时候，便开始信手涂鸦，在纸上乱涂乱画。 (2)象征阶段。此阶段的儿童能凭主观直觉印象描绘出物体的粗略形象。所画的形象只是一些简单的符号和标记，看不到完整的形象，基本保留了对象的形式特征。比如，此阶段儿童所画的“蝌蚪人”，头、躯干、四肢等各部分还未分化，仅仅保留了人区别于其他动物最基本的特征。他们画的图像与生活中真实的物体相距甚远，仅具有象征性的意义。
(3)图式阶段。这个时期的幼儿视觉感受性又有提高，眼动的轨迹越来越符合物象的外部轮廓，手部的小肌肉进一步发育，作画时能表现物象的主要部分和基本特征，不借助语言也能看出所画的内容。但是，该阶段的幼儿常以程式化的图形表现物象，缺乏写实性，形象不完整，喜欢用固定样式和画法表现不同的对象，画得比较概念化。

For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back.
