阅读下面《芦花荡》选段，完成下面题目。
       老头子向他们看了一眼，就又低下头去。还是有一篙没一篙地撑着船，剥着莲蓬，船却慢慢地冲着这里来了。
       小船离鬼子还有一箭之地，好像老头子才看出洗澡的是鬼子，只一篙，小船溜溜转了一个圆圈，又回去了。鬼子们拍打着水追过去，老头子张皇失措，船却走不动，鬼子紧紧追上了他。
       眼前是几根埋在水里的枯木桩子，日久天长，也许人们忘记这是为什么埋的了。这里的水却是镜子一样平，蓝天一般清，拉长的水草在水底轻轻地浮动。鬼子们追上来，看看就扒上了船。老头子又是一篙，小船旋风一样绕着鬼子们转，莲蓬的清香，在他们的鼻子尖上扫过。鬼子们像是玩着捉迷藏，乱转着身子，抓上抓下。
       一个鬼子尖叫了一声，就蹲到水里去。他被什么东西狠狠咬了一口，是一只锋利的钩子穿透了他的大腿。别的鬼子吃惊地往四下里一散，每个人的腿肚子也就挂上了钩。他们挣扎着，想摆脱那毒蛇一样的钩子。那替女孩子报仇的钩子却全找到腿上来，有的两个，有的三个。鬼子们痛得鬼叫，可是再也不敢动弹了。
       老头子把船一撑来到他们的身边，举起篙来砸着鬼子们的脑袋，像敲打顽固的老玉米一样。
       他狠狠地敲打，向着苇塘望了一眼。在那里，鲜嫩的芦花，一片展开的紫色的丝绒，正在迎风飘撒。
