虽然孩子们都对矩形格子涂色了，但都是N*N格子的格子涂色，
不像蒙德里安原作有“大色块小色块”的大小对比感觉（跨越两行），
这几天要上随堂课，我想就用“蒙德里安”做一个欣赏活动，全体孩子只要涂色就可以了。
一、彩色蒙德里安
测试方式：
1、一开始我尝试生成随机线条，遇到其他线条就停止，但是最终还是N*N格子的样式，填充时，整个画布都变成一种颜色。
2、后来，我准备在画布上随机生成12个黑框矩形（填充色3红3黄3蓝3黑），然后将每个矩形的左上角、右上角、左下角、右下角的位置延伸出两条黑线到画布边框（如果中途遇到黑色，就停止生成线条）
这么复杂的需求，多亏了AI对话大师，才能生成！！！
（矩形四个坐标的黑色线条延伸，问了三十几次才获得。）

随机生成20张
重点说明：
A4横板打印，所以我让短一点的Y（上下方向线条）生成，然后再生成长一点X（左右方向线条），否则左右线条生成后，上下线条可能都不出现了（上线线条接触到左右方向的黑线就终止）
二、黑白蒙德里安
我的教学目的是“三原色+黑色的涂色”，所以就不要填充颜色了
修改内容（填充白色）

稍微选一下图片，不要让孩子涂色面积过大，影响授课时间
也可以修改图形数量12个变成5个，看看小格子是不是不见了？
特别细小的小格子数量变少了。
2个矩形
1个矩形
修改，把代码放到最上面
一个矩形的8个方向线条都有了
再把彩色的蒙德里安也修改一下，确保8个线条都生成
