《从百草园到三味书屋》节选A①不必说碧绿的莱畦.(qí xí),光滑的石井栏,高大的皂荚树,紫红的桑椹;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。

②单是周围的短短的泥墙根一带,就有无限趣味。

③油蛉在这里低唱,蟋蟀们在这里弹琴。

④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.(jí jǐ)梁,便会拍的一声,从后窍喷出一阵烟雾。

⑤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。

⑥我于是常常拔它起来,牵连不听地拔起来,也曾因此弄坏泥墙,却从来没有见过一块根像人样。

⑦如果不怕刺,还可以摘到覆盆子,像小珊瑚珠攒.(zăn cuán)成的小球,又酸又甜,色味都比桑椹要好得远……B冬天的百草园比较的无味;雪一下,可就两样了。

拍雪人(将自己的全形印在雪上)和塑雪罗汉需要人们鉴赏,这是荒园,人迹罕至,所以不相宜,只好来捕鸟。

薄薄的雪,是不行的;总须积雪盖了地面一两天,鸟雀们久己无处觅食的时候才好。

扫开一块雪,露出地面,用一枝短棒支起一面大的竹筛来,下面撒些秕谷,棒上系一条长绳,人远远地牵看,看鸟雀下来啄食,走到竹筛底下的时候,将绳子一拉,使罩住了。

但所得的是麻雀居多,也有白颊的“张飞鸟”,性子很躁,养不过夜的。

1.用“√”给加点字选择正确读音。

2.A段文字中遗漏一句“有人说,何首乌根是有像人形的,吃了便可以成仙”应放在①——⑦何处? _____(填序号)3.A段文字除描写景物外,还写了四件趣事,请用小标题的形式概括两件你最感兴趣的。

_____________________________4.说说下面两句话中加点的字能否改为括号内的字,为什么?1.肥胖的黄蜂伏.(停)在菜花上。

九年级英语练习全册(精编版)

九年级英语练习全册(精编版)

精品英语九年级(U1----U10)中国人为什么要学英语假如有两个房间,房与房之间没有任何可以来往的门,在隔离墙的中间装有一块玻璃。

记住这是一块落地的单向透明玻璃。

也就是说,从一个房间可以看到另一个房间里发生的一切,而对于另一个房间,情况完全相反。

为了叙述更加清楚,我们不妨将可以看见对方的房间设为A房,只能被人看见的称为B房。

当然,为了更好的进行我们的假设,我们还可以将听筒加进来。

住在A房里的人可以听见B房里发出的声音,而住在B房的人对两间房之间的微妙关系一无所知。

单项玻璃对他来说,只意味着自家墙上有一面镜子。

他可以在镜子面前完成一种类似自我陶醉的审美。

比如用他来梳妆打扮,或者穿上风衣后在镜子前优雅地打一个转,说一些“嗯,今天挺精神”之类的话,如此等等。

接下来我们还得预设三个条件,与你一起挑选房间的人可能是一个智者、你生意上的敌人或者一条恶棍。

如果你必须挑其中的一个房间居住,你会挑选哪一间?我们一起来分析选择A房的理由:如果B房住着智者,你可以通过观察与倾听,从他身上学到你需要的东西。

比如他的举止,他阅读了哪些书,接待了哪些客人,表达了什么样的观点…….如果B房住着你生意场上的敌人,你同样可以通过观察与倾听(我们可以换上另一词组----监视与窃听)获得对你极其有利的情报。

比如他进行了哪些秘密的交易,你值得信赖的朋友是不是经常和他一起开香槟庆祝你新赔的一笔买卖……如果B房住着恶棍,你将见证丑陋与下流,并引以为戒。

当他杀人或有其他危及整个社区安全的行为时,你可以及时介入或报警。

以下是选择B房的理由:如果你愿意住进B房,可以是因为你自以为很漂亮,你喜欢被观赏。

你的观众包括智者、流氓以及随时想将你的钱财据为己有的人。

显然,你对自己的钱财并不关心,智慧对于你来说也毫无用处。

总而言之,你的乐趣就是照镜子,发表演讲、被人观赏或窃听。

当然,维持这种生活你需要有充足的耐心,你日复一日的活在监视之中,就像福柯笔下全景监狱里的囚徒,也就是说你并不知道什么时候别人在注视着你。

3.3 解方程(小考复习精编专项练习)六年级数学小升初复习系列:第三章式与方程(含知识点、练习与答案)一、方程,是指含有未知数的等式。

方程必须具备以下两个要素:一是含有未知数;二是等式。

式子同时具备这两个因素,才能称为方程。

二、解方程,是求出方程中未知数的值的过程,是求方程的解的具体方法。

其步骤是:(1)写“解”字;(2)方程最终化为ax=b(a≠0)的形式;(3)方程两边同时除以a,求出未知数的值。

还童石还童山下,有条清澈见底的溪流,溪底布满了大大小小的鹅卵石。

传说有一种七彩鹅卵石,谁捡到它,谁就能返老还童变成一个小孩。

然而,从来没人找到过这种“还童石”。

有一天,又有不少人到小溪中寻找“还童石”,他们当中有一位白发苍苍的老爷爷,也想返老还童变成一个小孩。

老爷爷不是为了乐一乐,而是为了实现埋在心里很久很久的一个愿望。

原来,在他还是小孩的时候,有一天在学校偷摘了一朵十分美丽的花,可他对老师撒了谎,没承认是他摘的。

这件事,他后悔了一辈子,因为他一生中,就撒了这么一次谎啊!现在,他站在溪水中,默默地向溪流诉说着自己的心愿……溪流明白了老爷爷的心事,悄悄地把一颗七彩鹅卵石送到了他的脚边。

老爷爷捡起了鹅卵石,果然变成了一个小孩。

他又惊又喜,跨出小溪飞奔起来。

他直奔一家花店,买了一株特别美丽的鲜花,又一口气奔进从前上过学的小学,把鲜花栽到花坛里。

当他心满意足地跨出学校的大门时,身子忽然变得又高又大,一下子恢复到了原来的模样,又成了个老爷爷。

那颗“还童石”呢,也就没了踪影。

期待已久的初雪,终于驾着西风急匆匆地赶来,轻轻落入黑山的怀抱。

在黑山的崇山峻岭,鹅毛般的雪花漫天飞舞,弥漫黑山的天空,有些急不可耐地尽情地飘着,舞着。

轻舞的雪花,像无数小小的天鹅,静静地拥入大地的怀抱。

雪落在树木、枯草、溪流上,一切便呈现出一种柔态,一种从未有过的妩媚。

花草树木似乎早已感觉到了,充满了欢快。

树校摇曳着,轻舞着,就连那些岩石几乎也要笑出声来。

洁白的雪地,把刚刚过去的夜晓和早晨连接起来了,给人以再生的新鲜感,而不仅仅只是空气。

而被夜晚过滤的空气,带着远方的气息,和着遥远的呓语,悠然而来。

天地间一片洁白,显得神圣而又静谧。

在雪的安抚下,黑山盖着厚厚的棉被。

大山、花草轻轻地叹息了一声,一滴珠泪滚落。

没有城市灯火的污染,没有来往车辆的(喧哗喧嚣),没有熙熙攘攘人流的惊扰。

黑山的雪,下得如此酣畅,如此(肆虐恣肆),整个天空成了它们表演的天堂。

或独舞,或群舞,或疾或徐,或南或北,或上或下。

如同欢快嬉笑的儿童,又如羞涩内向的少女,轻轻地从后走向前台。

雪花顽皮地打在我的脸上,落在我的睫毛上,然后慢慢地融化成一滴晶莹的水珠,为我带来了一丝清凉。

望着身边奇妙的雪景,我感慨万千,不由得在心底暗自赞叹着大自然的(鬼斧神工巧夺天工)。

感谢上天在寒冷的季节,派来了冬季的精灵,让这喧嚣的世界暂时安静了下来。

我一向喜欢雪,喜欢没有被污染的雪。

在这洁白面前,一切都逊色了。

尽情呼吸峨眉山的新鲜空气,心底极为留恋山上那场初雪。

1.画去文中括号里不恰当的词语。

2.选文第2自然段写出了雪__________的特点。

3.第3自然段画线句子运用了什么修辞手法?有什么表达效果?___________________________________4.下列对选文内容理解不正确的一项是()A.开头第一句写出了“我”对雪的无限期待和雪对世界的无比热爱。
