overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 15px; overflow-wrap: break-word !important;">1.在A4纸上用圆规和铅笔画好花朵，用彩色画笔涂上自己喜欢的颜色。如果你喜欢莲花，就可以画成中间是粉色的花，周边是绿色叶子的形状。画好以后，用剪刀剪下来。</span></h3><p style="margin-right: 32px;

overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 15px; overflow-wrap: break-word !important;">3.向准备好的碟子中倒入适量的水，然后将折叠好的纸花轻轻地平放到水中。（注意！只能将纸花轻轻平放在水面上，切忌不可直接浸入水中！）</span></h3><p style="margin-right: 32px;

overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 15px; overflow-wrap: break-word !important;">4.接下来，我们就可以静静观察水中的花朵，花瓣开始慢慢地绽放啦~</span></h3><h3><span style="max-width: 100%;
