I've loved my mother's desk since I was just tall enough to sit above the top of it.Moth er sat writing letters.Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be a most wonderful thing in the world.Years later, during her final illness, Mother kept different things for my sister and brother ."But the desk, "she said again, "is for Elizabeth."I never saw her angry, never saw her cry.I knew she loved me; she showed in action.Bu t as a young girl, I wanted to have heart-to-heart talks between mother and daughter.They never happened.And a gulf opened betwe en us.I was"too emotional(易动感情的)".But she lived"on the surface(表面)".As years passed and I had my own family.I loved my mother and thanked her for our hap py family.I wrote to her in careful words and asked her to let me know in any way she chos e that she did forgive me.My hope turned to disappointment, then little interest and, finally, peace-it seemed that nothing happened.I couldn't be sure that the letter had even got to Mother.I only knew that I had written it, and I could stop trying to make her into someone she was n ot.But the present of her desk told me, as she'd never been able to, that she was pleased that writing was my chosen work.I cleaned the desk carefully and found some papers inside-a photo of my father and a one-page letter, folded(折叠) and refolded many times.It was my letter."In any way you choose, Mother, you always chose the act that speaks louder than words."(1)The passage shows that________.A Mother was cold on the surface but kind in her heart to her daughter.B Mother was too serious about her daughter in words.C Mother wrote to her daughter in careful wo rds.D Mother wrote to her daughter in careless words.(2)The word"gulf"in the passage means________.A deep understanding between the old and the young.B different ideas between moth er and daughter.C free talks between mother and daughter.D part of the sea goi ng far in land.(3)What's best title of the passage?________A My Letter to Mother.B Mother and Children.C My Mother's Desk.D Talks be tween Mother and me.28. BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating(漂浮) in zero gravity(重力).However, there are also plenty of things that astronauts can't do because of their weightles s environment, and that's very sad.What's worse, they can't even let their sadness show, be cause it's impossible to cry in zero gravity.Of course, astronauts can still produce tears(眼泪).But crying is much more difficult in space, according to The Atlantic(大西洋月刊) in January.Without gravity, tears don't flow(流动) down out of the eyes like they do here on Earth.This means that when you cry in spac e, your tears have nowhere to go-they just stick(粘) to your eyes.In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks."T ears, "he said, "don't fall off of your eyes.They just stay there."Besides making your vision(视线) unclear, this can also cause physical pain.Back on Earth, tears are supposed to bring c omfort to the eyes.But that's not the case(情况) in space.The space environment dries out astronauts'eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort."My right eye is stinging(刺痛) like crazy, "Feustel told his teammate during the walk.Since gravity doesn't work in space, astronauts need some extra help to get rid of(除去) the tears.Feustel chose to rub his eyes against his helmet to wipe(擦) the tears away.Another choice is to just wait-"When the tears get big enough, they simply break free of the eyes and float around, "astrona ut Ron Parise told The Atlantic.There are lots of small things-things ike crying-that we are so used to on Earth.We usuallytake them for granted until they become a probl em in a totally different environment, like space.There, astronauts can't talk to each other d irectly.They also can't eat or drink in normal ways.They can't even burp打嗝), because there is no gravity to hold the food down in their stomach.If they do burp, th ey just end up throwing up(呕吐) everything in their stomach, according to the UK National Space Center.Therefore, perhaps it's only space explorers who can honestly say, "Gravity, you're the best ."(1)From Paragraphs 2and 3,we can know that________.A astronauts are unable to feel sad in space.B astronauts produce fewer tears in space .C tears produced in space flow down more slowly.D tears produced in space do n't flow downward.(2)What effect do tears hve on astronauts?________A They cause physical pain.B They bring comfort to them.C They make their vis on clearer.D They float around and cause trouble.(3)The underlined phrase"take them for granted"in paragraph 7means________.A find them important.B consider them useless.C need them during an emerge ncy.D fail to notice their presence.(4)Paragraph 7is mainly about________.A suggestions of how astronauts can stay comfortable in space.B other basic things th at are difficult to do in space.C why burping is impossible in space.D things hum an can't do without gravity.七、阅读短文,根据短文内容,从短文后的五个选项中选出能填入空白处的最佳选项.选项中有一项为多余选项.(共8分,每小题8分)29. Reading for pleasure is the easiest way to become a better reader in English.(60)________Some students say they don't want to read for pleasure.They say they want to use their time to learn the rules of the language and new words.They say that pleasure reading is too easy.Many experts say pleasure reading is very important f or learning Engish.Dr.Stephn Krashen,a famous expert on learning languages,says that pleasure reading helps you learn many important things about English.Students l earn more grammar and more words when they read for pleasure.(61)________ Dr.Krashen tells us that pleasure reading helps each student in a different way.Ea ch student needs to learn something different.Pleasure reading makes it possible for each s tudent to learn what he or she needs.(62)________When you read for pleasure,you choose your own books,and you don't have to remember everything.There are no tests on your pleasure reading bo oks.Pleasure reading will help you:●learn how English speakers use Englishread faster in English●find examples of good writing in English●(63)________●learn about the cultures of English speakersA.learn new wordsB.take an English testC.They also learn more about good writing.D.It is also the most important way.E.Reading for pleasure is not the same as studying.八、阅读短文,根据短文内容回答问题.(共10分,每小题10分)30.

Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the most wonderful thing in the world. Years later, during her final illness, Mother kept different things for my sister and brother. "But the desk", she said, "is for Elizabeth".I never saw her angry, never saw her cry. I knew she loved me, she showed it in action. But asa young girl, I wanted heart-to-heart talks between mother and daughter. They never happened. And a gulf opened between us. I was "too emotional". But she lived "on the surface". As years passed, I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me. I posted the letter and waited for her answer. None came. My hope turned to disappointment(失望), then little interest, finally, peace—it seemed that nothing happened. I couldn't be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.Now the present of her desk told me, as she'd never been able to, that she was pleased that writing was my chosen work, I cleaned the desk carefully and found some papers inside—a photo of my father and a one-page letter, folded(被折叠)and refolded many times. Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words.(1)The writer began to love her mother's desk ______.A after Mother diedB before she became a writerC when she was achild D when Mother gave it to her(2)The passage shows that ______.A Mother was cold on the surface but kind in her heart to her daughterB Mother wastoo serious about everything her daughter had done C Mother cared much about her daughter in words D Mother wrote to her daughter in careful words(3)The word "gulf" in the passage means ______.A deep understanding between the old and the youngB different ideas between the mother and the daughterC free talks between mother and daughterD part of the sea going far in land(4)What did Mother do with her daughter's letter asking forgiveness?A She had never received the letter.B For years, she often talked about theletter. C She didn't forgive her daughter at all in all her life. D She read the letter again and again till she died.(5)What's the best title of the passage?A My letter to MotherB Mother and ChildrenC My Mother's DeskD Talks Between Mother and Me18. Being an astronaut sounds cool, doesn't it? In space, they can do some pretty amazing things, like floating in zero gravity (重力).However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show ﹣ because it's impossible to cry in zero gravity.Of course, astronauts can' still have tears. But crying is much more difficult inspace. Without gravity, tears don't flow downward out of the eyes like they do on the earth. This means that when you cry in space, your tears have nowhere to go ﹣ they just stick to your eyes.In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off your eyes. They just stay there." Besides making your vision (视力) unclear, this can also cause physical pain. Back on the earth,tears are supposed to bring comfort to the eyes. But that's not the same in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is painful like crazy." Feustel told his teammate during the walk.Since gravity doesn't work in space astronauts need some extra help to get rid of the tears.Feustel chose to rub his eyes against his helmet (头盔) to wipe the tears away. Another choice is to just wait ﹣﹣ "When the tears get big enough, they simply break free of the eye and float around, astronaut Ron Parise said.There are lots of small things ﹣ things like crying that we are so used to on the earth. We usually take them for granted (认为理所当然), until they become a problem in a completely different environment, like space. There, astronauts can't talk to each other directly. They can't eat or drink in normal ways; They can't even burp (打嗝) because there is no gravity to hold the food down in their stomachs. If they do burp, they just endup throwing up (呕吐) everything in their stomachs, according to the UK National Space Center.________(88). Is crying more difficult in space than on the earth?________(89). What happens to tears when astronauts cry in space?________(90). Who experienced that the tears in space caused pain rather than comfort?________(91). How do astronauts get rid of the tears in space?________(92). Why can't astronauts burp in space?________(93). In the last paragraph, the writer says: perhaps it's only space explorers who can honestly say: "Gravity, you're the best." Do you agree with the writer? Why or why not?________四、填写适当的句子补全对话19.Reading for pleasure is the easiest way to become a better reading English. It is also the most important way. Some student say don't it to for pleasure. They say they want to use theirtime to use their time to learn the rules of the language and new words. They say that pleasure reading is too easy.Many experts(专家)say pleasure reading is very important for learning English. Dr. Stephen Krashen, a famous expert on learning languages, says that pleasure reading helpsyou learn many important things about English. Students learn more grammar and more words when they read for pleasure. They also learn more about good writing.Dr. Krashen tells us that pleasure reading helps each student in a different way.

北京市各区2014年中考语文二模试卷分类汇编:现代文阅读之文段

北京市各区2014年中考语文二模试卷分类汇编现代文阅读—文段[2014东城二模] (二)阅读下面两段文字,完成第16-17题。

(共12分)文段一西汉时期,汉武帝派遣张骞出使西域。

之后,汉朝与西域的使者、商人开始把中国的丝和丝织品,从长安通过河西走廊、今新疆地区,运往西亚和欧洲,又把西亚各国的奇珍异宝输入中国内地。

这条沟通东西交通陆上要道,就是历史上著名的丝绸之路。

汉武帝后,西汉的商人还经常出海贸易,开辟了一条通往西方的海上交通贸易要道。

从广东出发,抵达印度半岛南端和斯里兰卡岛,在此,中国的瓷器、丝绸、糖、五金等多种货物被运送至埃及、罗马,并进口香料、宝石等。

有的学者根据陆上丝绸之路加以引申,称它为海上丝绸之路。

至明清时期,海上丝绸之路取代陆上丝绸之路,贸易繁盛。

16.根据文段一内容,请写出西汉时期“丝绸之路”发展的两个表现。

(4分)文段二德国地理学家李希霍芬首次提出“丝绸之路”这个名称,因为他经过考察,认为当时路上运输的是丝绸。

而另一些学者则有不同的看法。

尽管西域考古挖掘出一些丝织品,但这只说明“丝绸之路”确实由东向西运送过丝绸。

一条路的货物流向应是双向的,从东向西运送的主要是丝绸,那么从西向东运的主要是什么呢?考古发现,河南安阳殷墟妇好墓中出土了750多件玉器,其中一部分玉经鉴定是来自新疆的和田玉。

和田玉首开了我国中原与边疆、与西方交流的运输通道。

到了汉代,丝绸商人利用这一古老的“玉石”通道又发展了丝绸贸易,中原地区的西域玉石消费量更是随之大增,到魏晋南北朝时期,从西域来的玉石广泛用作饰品、礼器、艺术品等。

和田玉一直是中原最受欢迎的物品。

可以认为“丝绸之路”叫做“丝玉之路”更为贴切。

17.根据文段二的内容,写出“另一些学者”关于“丝绸之路”名称的不同看法及其理由。

(8分)看法:理由:参考答案:16.示例:表现一:由陆上发展到海上,丝绸之路的线路增多。

表现二:出口物品由丝绸扩大到陶瓷、糖等,贸易种类扩大。

(共8分)①家庭教育对一个人的成长,特别是人格的养成具有其他教育无法取代的作用。

时下一些人没有敬畏,不知珍惜,究其原因,是不懂孝与俭。

在家教中应该力倡孝与俭,它们是敬惜之心的发端。

②为了教育子孙后代,古人精心制定了一些家规家训,其中,孝与俭是我国传统家教的重要内容。

曾国藩针对子弟生长于富贵家庭、惯于养尊处优的情况,在家训中,特别强调了“尽孝悌”、“倡勤俭”,教育子女要敬老爱幼,衣勿华美。

颜之推的《颜氏家训》教导子孙要赡养父母、尊敬父母,崇尚“俭而不吝”。

这些家教,在约束子弟、和睦家族家庭、维护社会安定等方面起了重要作用。

③今天,我们所说的孝是指善事父母。

首先是物质上赡养父母,其次是顺从,言语和气、态度谦恭、及时回应父母的要求。

孝的最高层次是发自内心、不带任何附加条件的对父母的敬爱。

④在家庭教育中培养子女正确的孝顺观,可以使子女懂得奉养父母,侍候长辈,是本分。

孝是做人的基本准则,是中华民族绵延不绝的美德,也是一个人爱家爱国的出发点。

子女只有从孝敬父母开始,才能继而爱小家,再进而爱大家、爱国家。

⑤俭朴是人对待物质一种态度和精神,体现出对劳动的尊重,对劳动成果的珍惜。

诸葛亮的《诫子书》不足百字,思想深刻。

“静以修身,俭以养德。

非淡泊无以明志,非宁静无以致远”,至今仍然被奉为圭臬①。

司马光专门写了一篇《训俭示康》,指出崇俭戒奢、劳谦终吉。

《朱子家训》中的“一粥一饭,当思来之不易;半丝半缕,恒念物力维艰”,告诉我们⑥因此,在家教中倡导俭朴,能够培养人们从小自我克制欲望的能力和精神,使人不滋生贪婪物欲,不贪图享受,少一份索取,多一份奉献。

⑦在家庭教育中从小培养敬老尊长,参加劳动等意识和习惯,从而体会劳动的不易和父母的辛苦,才能使人具备孝和俭的美德。

【注】①[圭臬]借指准则和法度。

忌不自信,而复问其妾曰:“吾孰与徐公美?”妾曰:“徐公何能及君也?”旦日,客从外来,与坐谈,问之:“吾与徐公孰美?”客曰:“徐公不若君之美也。

”明日,徐公来,孰视之,自以为不如;窥镜而自视,又弗如远甚。

暮寝而思之,曰:“吾妻之美我者,私我也;妾之美我者,畏我也;客之美我者,欲有求于我也。

”于是入朝见威王,曰:“臣诚知不如徐公美。

臣之妻私臣,臣之妾畏臣,臣之客欲有求于臣,皆以美于徐公。

今齐地方千里,百二十城,宫妇左右莫不私王,朝廷之臣莫不畏王,四境之内莫不有求于王。

由此观之,王之蔽甚矣!”王曰:“善。

”乃下令:“群臣吏民,能面刺寡人之过者,受上赏;上书谏寡人者,受中赏;能谤讥于市朝,闻寡人之耳者,受下赏。

”令初下,群臣进谏,门庭若市;数月之后,时时而间进;期年之后,虽欲言,无可进者。

(2分)答:三、现代文阅读(共36分)(一)阅读《装穷的亿万富翁》,完成第13—15题。

(共16分)装穷的亿万富翁三秋树①2013年9月,98岁的杰克〃麦克唐纳走了。

按其生前遗嘱,他拥有的1.876亿美元(约合11.4亿元人民币)被分为三份,分别捐给了西雅图儿童医院研究所、华盛顿大学法学院、救世军组织。

②消息传出,麦克唐纳最后的居留之所——西雅图“老人之家”的老伙伴们都惊呆了。

要知道,这个1997年便入住这家平民养老院的老头儿平时非常抠门儿——他喜欢收集各种优惠券,非打折的商品不买,时常为节省几美分而走上几站路。

95岁那一年,他应邀去母校华盛顿大学法学院参加晚宴,他舍不得打的,来去坐的都是公交车。

③就是这样一位节俭到骨子里的老人,却在身后留下巨额财产做慈善。

陪伴麦克唐纳一起装穷、帮他保守这个秘密长达40年的继女丹尼斯,同样震惊于继父的这份坚守。

④1971年,麦克唐纳与丹尼斯的母亲结婚。

那时,丹尼斯与姐姐都已经成家立业。

对于这个住着小房子、开着二手车的老男人,两姐妹秉承的原则是妈妈愿意就好。

事实上,二人婚后的生活非常开心,一年中有将近10个月的时间外出旅行,偶尔回国,母亲会用在世界各地学到的厨艺宴请宾朋。

担心两位玩疯了的老人会“坐吃山空”,丹尼斯曾经小心翼翼地想给他们一些帮助,不想,麦克唐纳却将自己的家底全都向丹尼斯摊了牌——继承了父母的遗产,加之这些年来在股市里的收益,麦克唐纳是一个地道的亿万富翁。

⑤“我不想被贪财的人纠缠,也不想被物质驾驭或奴役,所以,请你们帮我保守这个秘密。

等到有一天我走了,把我全部的钱都捐出去。

”⑥那一刻,丹尼斯觉得自己被继父征服了。

如果说炫富需要勇气的话,那么装穷则需要智慧。

老夫妻时常去排队抢购打折的日用品,能步行的时候绝不开车,至于穿着,丹尼斯常常笑他们跟这个时代隔着20年的距离,有着复古般的时尚。

有一次,丹尼斯偷偷地问妈妈:“跟这样一个节俭过度的人生活,会不会觉得委屈?”妈妈告诉丹尼斯:“跟他生活后,我生命的大门仿佛刚刚被打开一般。

我们一起过最节约的生活,也是最简单的生活,那种富足是其他人体会不到的。

”妈妈还告诉丹尼斯,麦克唐纳不是真的吝啬,他曾经多次陪着他匿名向多家慈善机构捐款。

“他写支票的样子帅极了!当把钱无偿支付给那些需要钱的人的时候,你会觉得自己变得高尚了,你会觉得这个男人朴素得伟大,你会为跟这样一个无私而低调的人生活在一起而感到骄傲。

”⑦1997年,年事已高的麦克唐纳夫妇一起搬进了西雅图的一家平民养老院——“老人之家”。

在那里,他们依然过着勤俭得几近穷苦的日子,所有人都觉得这是一对生活拮据的夫妻。

两年后,妻子去世了,麦克唐纳变成了一个孤独的老头儿,甚至有人拿他来教育前来探望自己的子女:“华盛顿法学院毕业又怎么样?还不是潦倒一生?连喝个果汁都要先计算一下自己兜里的钱,衣服破成那样子,也假装看不见。

”⑧2010年,身体每况愈下的麦克唐纳告诉丹尼斯,他希望以一个慈善家的身份被人记住——他的上亿资产全部捐给慈善机构。

对于身后事,他对丹尼斯说:“一切从简,能听到教堂的钟声就足够了。

”丹尼斯含泪听完继父的安排,她觉得,穿着破衣烂衫的继父心里,藏着一座金矿。
