Liang Xianghua, a 22-year-old girl from Guangxi University, has been well-known in China for her sand painting since her first work was used by CCTV.     "Sand paintings really attracted me while I was watching a video performance, I was surprised by how this artwork melted people's heart in minutes" said Liang. "I fell in love with the way the sand pictures, music and the light combined（融合）with each other to make a flow of emotion（情感）. You can express things freely."

In order to master the skills, Liang practised for several hours every day. She said that she couldn't even do the first step well of throwing sand onto the glass. But she didn't give up.     After finding success with her first show, she was invited to do many performances. This made her quite tired. She decided to give a stop and focus on her study. But an invitation from Malaysia changed her mind just as she was about to wash the sand from her hands. This spring, she was invited by a Malaysia middle school to give a performance. Liang didn't want to do a live show, but agreed to do a video for the school, showing its development over the years.     She received praise for her work and the performance was described as an eye-opener for the students. This made her wonder if her art would be more meaningful if she made it for the poor students.     As a volunteer this time, she plans to take part in a summer programme offering help to pupils in a mountain area, and give the most wonderful show in her life.

下列哪项不是细胞凋亡的意义

    ①我冒了严寒，回到相隔二千余里，别了二十余年的故乡去。

    ②时候既然是深冬；渐近故乡时，天气又阴晦了，冷风吹进船舱中，呜呜的响，从篷隙向外一望，苍黄的天底下，远近横着几个萧索的荒村，没有一些活气。我的心禁不住悲凉起来了。

    ③这来的便是闰土。虽然我一见便知道是闰土，但又不是我这记忆上的闰土了。他身材增加了一倍；先前的紫色的圆脸，已经变作灰黄，而且加上了很深的皱纹；眼睛也像他父亲一样，周围都肿得通红，这我知道，在海边种地的人，终日吹着海风，大抵是这样的。他头上是一顶破毡帽，身上只一件极薄的棉衣，浑身瑟索着；手里提着一个纸包和一支长烟管，那手也不是我所记得的红活圆实的手，却又粗又笨而且开裂，像是松树皮了。

    ④我这时很兴奋，但不知道怎么说才好，只是说：

    ⑤“阿！闰土哥，——你来了？……”

    ⑥我接着便有许多话，想要连珠一般涌出：角鸡，跳鱼儿、贝壳，猹，……但又总觉得被什么挡着似的，单在脑里面回旋，吐不出口外去。

    ⑦他站住了，脸上现出欢喜和凄凉的神情；动着嘴唇，却没有作声，他的态度终于恭敬起来了，分明的叫道：

    ⑧“老爷！……”

    ⑨我似乎打了一个寒噤；我就知道，我们之间已经隔了一层可悲的厚障壁了。我也说不出话。

    ⑩他回过头去说，“水生，给老爷磕头。”便拖出躲在背后的孩子来，这正是一个廿年前的闰土，只是黄瘦些，颈子上没有银圈罢了。“这是第五个孩子，没有见过世面，躲躲闪闪……”

    ……

    ⑪我在蒙胧中，眼前展开一片海边碧绿的沙地来，上面深蓝的天空中挂着一轮金黄的圆月。我想：希望是本无所谓有，无所谓无的。这正如地上的路；其实地上本没有路，走的人多了，也便成了路。
