现代文语段阅读（一）（12分）不必说碧绿的的菜畦，光滑的的石井栏，高大的的皂荚树，紫红的的桑葚；也不必说鸣蝉在树叶里长吟，肥胖的黄蜂伏在菜花上，轻捷的叫天子（云雀）忽然从草间直窜向云霄里去了。单是周围的短短的泥墙根一带，就有无限趣味。油蛉在这里低唱，蟋蟀们在这里弹琴。翻开断砖来，有时会遇见蜈蚣；还有斑蝥，倘若用手指按住它的脊梁，便会啪的一声，从后窍喷出一阵烟雾。何首乌藤和木莲藤缠络着，木莲有莲房一般的果实，何首乌有臃肿的根。有人说，何首乌根是有像人形的，吃了便可以成仙，我于是常常拔它起来，牵连不断地拔起来，也曾因此弄坏了泥墙，却从来没有见过有一块根像人样。如果不怕刺，还可以摘到覆盆子，像小珊瑚珠攒成的小球，又酸又甜，色味都比桑葚要好得远。8．文中划线句能否将“紫红的桑葚”与“碧绿的菜畦”对调，为什么？（3分）9．作者在文中描写了百草园中的景色，也回忆了童年时一些有趣的活动。请仿照示例概括活动的内容。（3分）翻断砖；

（2）当时，我们所在的江南小城没有高层和小高层。经过千番比较万番排除之后，我们拖着疲惫的身躯，满心欢喜地搬进了运河边一幢六层楼房的第五层——白天能纵情鸟瞰千年运河，夜晚能枕着运河悠悠的风声和水声而眠，该多么惬意啊。 （3）远亲不如近邻。初来乍到，免不了要去拜访列位高邻。六楼住的是一对新婚不久的高校教师，男的文质彬彬，女的温文尔雅，家中窗明几净，地板一尘不染。能有这样的高邻，我们暗暗喜在心里。（4）然而，我们的喜悦很快便被一个烂桔子击碎了。 （5）一个美丽的黄昏，微风习习，汩汩的运河水将红艳艳的夕阳揉碎在波纹间，幻化出一片梦一般绚丽的景观。我凭栏而立，正自心醉神迷，忽听“砰”的一声，一个球状的橙色物体重重地击打在晾衣架上，酸臭的味儿炸裂开来，逼得我直往后退。 （6）在好奇心的驱使下，我悄悄探出脑袋，发现女主人姿态婀娜地倚在阳台上，翘着兰花指儿，正优雅地嗑着瓜子，瓜子壳儿天女散花般向下飘飞。我的心也紧跟着直往下坠。 （7）休完年假回家，打开阳台的窗子，我不觉愣住了：一条八成新的薄棉絮斜斜地挂在晾衣架上。这肯定是楼上高邻的！我二话不说，拎起棉絮径直敲开了实在不想敲开的门。好一会儿，门被打开了一道缝缝，缝缝里探出了男主人的脑袋：“哦，这棉絮是我们扔掉的。你直接扔掉好了，不用拿上来的。”我当时的感受，用现在的话来说，就一字：晕。 （8） 有了这样的高邻，入住才一年，我们便开始考虑换房了。 （9）周日清晨，妻子正准备晾衣服，突然惊叫起来。我跑过去一看，只见一个比初升的太阳更耀眼的红色的塑料袋，装了大半袋的桔子皮和香蕉皮，高挂在晾衣架上，正耀武扬威地在我们面前晃悠。盛怒之下，我抱定得罪高邻的决心，不顾妻子的劝阻，奋笔疾书： 招领启事 今日，本人在自家晾衣架上捡到垃圾一袋，请失主自觉领回。此致敬礼！501室 某年某月某日 （10）书写完毕，我立即将招领启事贴到一楼楼梯口，并找来榔头和钉子，将装满垃圾的袋子挂在招领启事旁边。 （11）傍晚，垃圾不见了，招领启事也被撕掉了。 （12） 从那以后，我们再也没有动过搬家的念头。12 试分析第（5）段中“一个美丽的黄昏，微风习习，汩汩的运河水将红艳艳的夕阳揉碎在波纹间，幻化出一片梦一般绚丽的景观”在文中的作用。（3分）13 第（6）段“我的心也紧跟着直往下坠”一句中的“坠”能否换成“落”，为什么？（3分）14 在第（7）段中，作者写道：“我当时的感受，用现在的话来说，就一字：晕”请揣摩“我”此时的心理，写一段不少于30字的心理描写。（3分）15 根据全文内容，说说标题“高邻”的作用。（3分）三
