4、 可以從“造福天下黎民,救普天下人的性命”來說,也可以進(jìn)一步說“醫(yī)書之誤,有草菅人命之?!眮碚f,也可以從“補(bǔ)充說明救命之恩,言而有信”等方面考慮。

六、仿寫答案:
1.無論是苦心研究最終發(fā)現(xiàn)“鐳”的居里夫人,還是身患重病卻探究出宇宙成因的史蒂芬 金;無論是勤學(xué)數(shù)十年才撰成《資本論》的馬克思,還是潛心鉆研反復(fù)試驗(yàn)而發(fā)明白熾燈的愛迪生。

2、 略
語文如水
水,不拘泥于任何形狀,裝在杯中的水,形狀由杯子的形狀來決定,飛流直下三千尺水,就無法用形狀來描述它了。由此,我不禁想起王蒙曾提出的“語文是什么”的問題。有人說,語文是整天的題海戰(zhàn)術(shù),有人說是老土的“八股文”等等。
語文難道就是成天做題,一個(gè)學(xué)期捏著鼻子寫幾篇作文?不,這一問題應(yīng)到大自然和生活中去尋找。
庭前花開花落,天空云卷云舒,你覺得真好,這就是語文;初升的太陽光芒萬丈你覺得生機(jī)勃勃,這就是語文;如血的殘陽映紅半邊天,讓人無限留戀,別忘了這也是是語文。語文是那巍巍昆侖,是那草葉上久久不肯滴落的露珠,是在古城舊都中國色天香的牡丹;語文是那無聲的冷月,是那靜謐的荷塘,是大海滔天白浪里的打魚船,是那青天里的一行白鷺,是那沉舟側(cè)畔的萬點(diǎn)白帆,是那山重水復(fù)后的柳暗花明
潛過了落滿梨花的大自然,讓我們到生活中去尋找它的答案。
語文給予我們聆聽音樂的耳朵,欣賞繪畫的頭腦與眼睛。當(dāng)你聽到一首美妙的歌,你覺得這詞真好,想記住它,這就是語文;當(dāng)你看到一幅畫,被其中的景象吸引,于是你搜腸刮肚地想盡華美的詞語來形容它,這也是語文;當(dāng)你參加班干部競選演講,組織廣播稿件,主持會議,這還是語文。
“大江東去,浪淘盡,千古風(fēng)流人物”,語文從詩人口中娓娓道出;語文被當(dāng)陽橋頭張飛一聲吼出;語文從憂國憂民的范仲淹的筆端流出;語文在潯陽江頭的琵琶弦上回蕩;語文帶我們到天姥山的仙人洞里體驗(yàn)神奇,到景陽岡的青石上感受驚險(xiǎn);語文讓我們深味“逝者如斯”的感慨,“才下眉頭,卻上心頭”的憂愁,“對酒當(dāng)歌,人生幾何”的無奈,“秋陰不散霜飛晚,留得殘荷聽雨聲”的蕭瑟……
這就是語文,如此多姿,它把拘泥于什么公式、定義,在不同人的眼中它體現(xiàn)著不同的形態(tài)。
(三)王雪芝答案
一、古詩文積累:
1、 君不見走馬川行雪海邊,平沙莽莽黃入天。
2、 欲為圣明除弊事,肯將衰朽惜殘年。
3、 時(shí)難年荒世業(yè)空,弟兄羈旅各西東。
4、 黑云壓城城欲摧,甲光向日金鱗開。
5、 角聲滿天秋色里,塞上燕脂凝夜紫。
6、 才始送春歸,又送君歸去。
7、 半卷紅旗臨易水,霜重鼓寒聲不起。
8、 無限河山淚,誰言天地寬。
9、 報(bào)君黃金臺上意,提攜玉龍為君死。
10、 請為父老歌,艱難愧深情。
11、 歌罷仰天嘆,四坐淚縱橫。
12、 花近高樓傷客心,萬方多難此登臨。
二、給加點(diǎn)的字注音或給注音加漢字。
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、廣袤18、深邃19、篤信20、睿智
三、《愛蓮說》
1《周元公集》周敦頤 茂書 北宋哲學(xué)家
2親近而不莊重 應(yīng)當(dāng) 少 洗滌
3、 a出淤泥而不染,濯清漣而不妖
b中通外直,不曼不枝
c香遠(yuǎn)益清,亭亭凈植
d蓮,花之君子者也
4、 文中用菊花正襯牡丹反襯突出蓮花的高貴品質(zhì)表達(dá)了作者不慕名利,潔身自好的情操。
5、 自圓其說即可。
