风落之果

在某便利店门口,看到一女士掉了1元硬币,刚好滚到不远处的一个乞丐面前,他当时盘腿而坐,因下肢残疾,所以他捡起那枚硬币,极吃力地高高举起来,要还给那女士。那女士微笑着,摆摆手,顺水推舟,就把1元钱给了乞丐。我看到这一切,会心一笑,这是都市里的一幅即兴画卷,很美,还有淡淡的喜乐色彩,泛着些许温暖。

小时候,在乡下,很穷。但是妈妈常会给我们六个兄弟姐妹一些惊喜,因为她可以变魔术似的,在桌上摆出一些时令水果,这是匪夷所思的,因为我们买米的钱都没有,怎么可以奢侈地吃到水果?但是妈妈做到了。春天有枇杷、夏天有桃子龙眼杨梅荔枝芒果、秋天有石榴橄榄、冬天有柿子橘子板栗……那是些丰美富足的早晨,妈妈总是第一个起床,然后第一个跑到不远的“万果园”里去捡“风落之果”,在水果成熟季节,晚上总有风吹落一些被小鸟啄过或者承受不了自身重量的果实,果园主人对于起大早来捡落果的穷人,一直心存宽厚与仁慈,没有刁难,而是默许。有一次刮台风,龙眼树下都是果实,我们几个孩子高兴得手舞足蹈,大叫“老天有眼”,我们可以大饱口福了。结果,我们被妈妈臭骂一顿:“我们怎么可以幸灾乐祸?人家的损失有多大,我们怎么可以高兴呢?”妈妈的想法是朴素的,人家落难时,我们不能趁火打劫;只有别人丰收时,我们才可以分享他人的“风落之果”。  

多年过去了,我常常梦到那些诱人可爱的“风落之果”。

今天,我又看到了它,那是一枚滚落在乞丐面前的硬币。

小题1:第1段中,作者说:“我看到这一切,会心一笑,这是都市里的一幅即兴画卷,很美,还有淡淡的喜乐色彩,泛着些许温暖。”请你分析一下,“美”体现在哪里?(2分)
