[简答题]石榴
郭沫若
①五月过了,太阳增加了它的威力,树木都把各自的伞盖伸张了起来。不想再争妍斗艳的时候,有少数的树木却在这时开起了花来。石榴树便是这少数树木中的最可爱的一种。
②石榴有梅树的枝干,有杨柳的叶片,奇崛而不枯瘠,清新而不柔媚,这风度实兼备了梅柳之长,而舍去了梅柳之短。
③最可爱的是它的花,那对于炎阳的直射毫不避易的深红的花,单瓣的已够陆离。双瓣的更为华丽,那不是夏季的心脏吗?
④单那小茄形的骨朵已经就是一种奇迹了。你看,它逐渐翻红,逐渐从顶端整裂为四瓣,任你用怎样犀利的剪刀也都剪不出那样的匀称,可是谁用红玛瑙琢成了那样多的花瓶儿,而且还精巧地插上了花?
⑤单瓣的花虽没有双瓣的豪华,但它却更有一段妙幻的演艺,红玛瑙的花瓶儿由希腊式的安普刺变为中国式的金垂(殷、周时代古味盎然的一种青铜器)。博古家所命名的各种绣彩,它都是具备着的。
⑥你以为它真是盛酒的金罂吗?它会笑你呢。秋天来了,它对于自己的戏法好像忍俊不禁地,破口大笑起来,露出一口皓齿,那样透明光嫩的皓齿你在别的地方还看见过吗?
⑦我本来就喜欢夏天。夏天是整个宇宙向上的一个阶段,在这时使人的身心解脱尽重重的束缚。因而我更喜欢这夏天的心脏。
⑧有朋友从昆明回来,说昆明石榴特别大,籽粒特别丰腴,有酸甜两种,酸者味更美。
⑨禁不住唾津的潜溢了。
本文作者采用了什么写作手法,其意在借石榴表现什么?
