1.无论是苦心研究最终发现“镭”的居里夫人,还是身患重病却探究出宇宙成因的史蒂芬 金;无论是勤学数十年才撰成《资本论》的马克思,还是潜心钻研反复试验而发明白炽灯的爱迪生。

3、.有勤,才有了祖逖“闻鸡起舞”的美谈,也才有了雄才大展、北伐报国的伟业;有勤,才有了曹雪芹“披阅十载、增删五次”的壮举,也才有了世界文学史上不朽的名著《红楼梦》。
七、文学放飞
1、美国 《老人与海》 桑提亚哥 顽强勇敢,不向命运困难低头,有执着的信念。
2、 略
语文如水
水,不拘泥于任何形状,装在杯中的水,形状由杯子的形状来决定,飞流直下三千尺水,就无法用形状来描述它了。由此,我不禁想起王蒙曾提出的“语文是什么”的问题。有人说,语文是整天的题海战术,有人说是老土的“八股文”等等。
语文难道就是成天做题,一个学期捏着鼻子写几篇作文?不,这一问题应到大自然和生活中去寻找。
庭前花开花落,天空云卷云舒,你觉得真好,这就是语文;初升的太阳光芒万丈你觉得生机勃勃,这就是语文;如血的残阳映红半边天,让人无限留恋,别忘了这也是是语文。语文是那巍巍昆仑,是那草叶上久久不肯滴落的露珠,是在古城旧都中国色天香的牡丹;语文是那无声的冷月,是那静谧的荷塘,是大海滔天白浪里的打鱼船,是那青天里的一行白鹭,是那沉舟侧畔的万点白帆,是那山重水复后的柳暗花明
潜过了落满梨花的大自然,让我们到生活中去寻找它的答案。
语文给予我们聆听音乐的耳朵,欣赏绘画的头脑与眼睛。当你听到一首美妙的歌,你觉得这词真好,想记住它,这就是语文;当你看到一幅画,被其中的景象吸引,于是你搜肠刮肚地想尽华美的词语来形容它,这也是语文;当你参加班干部竞选演讲,组织广播稿件,主持会议,这还是语文。
“大江东去,浪淘尽,千古风流人物”,语文从诗人口中娓娓道出;语文被当阳桥头张飞一声吼出;语文从忧国忧民的范仲淹的笔端流出;语文在浔阳江头的琵琶弦上回荡;语文带我们到天姥山的仙人洞里体验神奇,到景阳冈的青石上感受惊险;语文让我们深味“逝者如斯”的感慨,“才下眉头,却上心头”的忧愁,“对酒当歌,人生几何”的无奈,“秋阴不散霜飞晚,留得残荷听雨声”的萧瑟……
这就是语文,如此多姿,它把拘泥于什么公式、定义,在不同人的眼中它体现着不同的形态。
(三)王雪芝答案
一、古诗文积累:
1、 君不见走马川行雪海边,平沙莽莽黄入天。
2、 欲为圣明除弊事,肯将衰朽惜残年。
3、 时难年荒世业空,弟兄羁旅各西东。
4、 黑云压城城欲摧,甲光向日金鳞开。
5、 角声满天秋色里,塞上燕脂凝夜紫。
6、 才始送春归,又送君归去。
7、 半卷红旗临易水,霜重鼓寒声不起。
8、 无限河山泪,谁言天地宽。
9、 报君黄金台上意,提携玉龙为君死。
10、 请为父老歌,艰难愧深情。
11、 歌罢仰天叹,四坐泪纵横。
12、 花近高楼伤客心,万方多难此登临。
二、给加点的字注音或给注音加汉字。
1、xia 2.jue 3.mi 4.hui 5.gui6.ke 7.juan 8.zhi 9.zhen 10.tian
11.you 12.shun 13.shen 14.bei 15.jian 16.媲美 17、广袤18、深邃19、笃信20、睿智
三、《爱莲说》
1《周元公集》周敦颐 茂书 北宋哲学家
2亲近而不庄重 应当 少 洗涤
3、 a出淤泥而不染,濯清涟而不妖
b中通外直,不曼不枝
c香远益清,亭亭净植
d莲,花之君子者也
4、 文中用菊花正衬牡丹反衬突出莲花的高贵品质表达了作者不慕名利,洁身自好的情操。
5、 自圆其说即可。
