Many times he’s playing a basketball with one hand, or laughing with a friend about something that I 17 quite understand, or crying about something he may or may not want to talk about while I’m on the other end of the phone. I just listen and empathize (同情) or laugh with him—just share his current (當(dāng)前的) 18 . I always let him control the 19 , and the time he’s on the phone with me. Many times I just listen to him play, or play games we’ve made up together that we can play over the 20 .The only time I take control of the 21 is when he’s ready to say goodbye at night. Often there are four special 22 I say to him every night. One night I thought maybe he was tired to hear those, so I didn’t say them. He 23 called me back and told me that I forgot to say those sentences! I haven’t missed saying them since then!My friends all know that he is the most important for me. 24 I’m in church(教堂), or some place where I really can’t take his call, I always politely excuse myself and talk to him, even if it’s just for a minute to tell him I’ll call him back in a few minutes.He knows that he takes first place in my heart.15.

All she knew was that he was very sick and they had no money. Only a very expensive operation could save him now and there was no one to lend them the money.When she heard her daddy say to her tearful mother,“Only a miracle (奇跡)can save him now,”the little girl went to her bedroom and pulled her money from its hiding place and counted it carefully.She hurried to a drugstore(藥店)with the money in her hand. “And what do you want?” asked the salesman. “It’s for my little brother,” the girl answered. “He’s really,really sick and I want to buy a miracle.” “Pardon?” said the salesman. “My brother Andrew has something bad growing in-side his head and my daddy says only a miracle can save him. So how much does a miracle cost?” “We don’t sell a miracle here,child. I’m sorry,”the salesman said with a smile.“Listen,if it isn’t enough,I can try and get some more. Just tell me how much it costs.”A well-dressed man heard it and asked,“What kind of a miracle does your brother need?”“I don’t know,”she answered with her eyes full of tears(眼淚). “He’s really sick and mum says he needs an operation. But my daddy can’t pay for it,so I have brought all my money.” “How much do you have?” asked the man. “$ 1.11,but I can try and get some more,” she answered.“Well,what luck,”smiled the man. “$ 1.11,the price of a miracle for little brothers.”He took up the girl’s hand and said, “Take me to where you live. I want to see your brother and meet your parents. Let’s see if I have the kind of miracle you need.”That well-dressed man was Dr Carlton Armstrong,a famous doctor.

Andrew was in fact not so sick as they had thoughtCIt seems to be strange to you there is a blind spot(點(diǎn)) on the eyes. Here is an interesting experiment that can make something disappear, when one eye is open. Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you’ll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.Why does the letter disappear It is because there is a blind spot on the eye. When the image of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.( )31.The writer of the passage thinks that _____ there is a blind spot on the eye.

Each age has its pleasures and its pains(痛苦), and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets(后悔).When a young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way he used to as a child, he will go hungry. And if he breaks the laws of society(社會(huì)) as he used to break the laws of his parents, he may go to prison.

(2分)_____________________________________________________________________________12、新的金融危機(jī)將對(duì)中國(guó)產(chǎn)生哪些影響?(3分)_____________________________________________________________________________(四)(4分)給最愛(ài)的他們安全感①每個(gè)孩子都被父母指責(zé)過(guò)不懂事,那句“都是為了你好”聽(tīng)過(guò)千遍萬(wàn)遍,“知道,知道,我都知道”也答了千遍萬(wàn)遍。為什么這樣的事情一直在發(fā)生?②我們的父母有個(gè)有趣的標(biāo)準(zhǔn),聽(tīng)話的就是好孩子,不聽(tīng)話的就是壞孩子。換言之,就是停留在父母框架里的就是父母喜歡的孩子,任何突破框架的企圖都是叛逆、不聽(tīng)話、不懂事甚至不孝順。因?yàn)樗麄兣挛覀冏隽嗽愀獾倪x擇——他們心里沒(méi)有安全感,對(duì)框架之外的世界沒(méi)有信心。③如果你希望父母尊重你的選擇,你必須要給他們安全感——你能對(duì)自己的選擇負(fù)責(zé),可以從小事做起,甚至從妥協(xié)做起。讓父母有安全感有兩條路,一條是最方便的聽(tīng)話之路,父母要求你做什么就做什么。這條路在你長(zhǎng)大之后會(huì)越來(lái)越難走,你會(huì)分不清楚“他們想要什么”和“你想要什么”。④一條就是有些難度的獨(dú)立之路,你要比他們更強(qiáng)大。這句話的意思不是你要通過(guò)壓倒他們來(lái)達(dá)到強(qiáng)大,而是你要通過(guò)理解他們和保護(hù)他們變得更強(qiáng)大,強(qiáng)大到他們能夠意識(shí)到你能照顧好自己了,甚至能照顧他們了。不要等他們老了,你才覺(jué)得該照顧他們了。說(shuō)到這里,你會(huì)不會(huì)笑——給父母安全感?⑤真的,試試從這個(gè)角度去理解你們的關(guān)系,就會(huì)明白許多的沖突并不是他們不尊重你,而是他們沒(méi)有安全感,他們不知道你已經(jīng)長(zhǎng)大。⑥所以你要更努力,試著去理解自己的父母。他們?yōu)槟闾峁┝四敲撮L(zhǎng)久的愛(ài)和安全感,現(xiàn)在,輪到你了。長(zhǎng)大吧!13、本文的中心論點(diǎn)是什么?(2分)_____________________________________________________________________________14、第②段畫線句子主要運(yùn)用了什么論證方法?有何作用? (2分)(五)(14分)牽入我家的絲瓜花①鄰家院角落里種的絲瓜花,在搭好涼棚后,級(jí)級(jí)攀登而上,一路牽線而來(lái),爬上高高的院墻,纏上長(zhǎng)長(zhǎng)的電線,一路牽入我家。細(xì)長(zhǎng)的觸角伸展著,一路向前,有點(diǎn)不牽來(lái)就不罷休的架勢(shì),活像撒野的小孩,吵著嚷著,牽著爬著,伏著吊著就是要牽入我家。②一路歡歡喜喜牽來(lái)的絲瓜花,呼朋引伴似的,千朵萬(wàn)朵地拼了命地開(kāi)黃花,真有千朵萬(wàn)朵壓藤低的架勢(shì)。如懷春的鄉(xiāng)村姑娘,頂著滿頭黃花,仰著張張樸素、純凈的笑臉,把千絲萬(wàn)縷的滿架綠葉黃花牽到我家廚房的窗前,只等我深情回眸。我家廚房朝西,夏天西曬得厲害,火一樣的太陽(yáng)直曬到天黑,才戀戀不舍地離去,這一路牽來(lái)的絲瓜花,讓我每每在鍋碗瓢盆間揮汗如雨里染一抹翠綠,沐一陣清涼。喜歡這爬上架,牽到我家的絲瓜花。③絲瓜花,我熟知的老友。在農(nóng)村的盛夏,它應(yīng)是最熱鬧最常見(jiàn)的風(fēng)景。房前屋后,田頭地邊,橋頭溝邊都是它黃花插滿頭的倩影,它像活潑的村姑,有著素凈的笑臉,有著曼妙柔弱的身姿,有著纖纖巧手,或編織,或纏繞,或爬,或吊,或伏、或牽,或在草垛上,在屋檐下,在泡桐樹(shù)上,在曬衣服的鐵絲線上,它都能風(fēng)情萬(wàn)種地舞蹈,跳出鄉(xiāng)村最熱烈最熱鬧最動(dòng)人的舞蹈。單一的小朵黃花,開(kāi)在鄉(xiāng)野廣闊的林原花海里,實(shí)在不起眼,但是它花團(tuán)錦簇,成千朵萬(wàn)朵地開(kāi),那氣勢(shì),真是壯觀,那場(chǎng)景,真是熱鬧。原來(lái),每一場(chǎng)花事,只要一心齊發(fā),蔚為大觀,都是能震撼人心的。④兒時(shí),母親每年總是在家門前的水溝邊上丟幾粒絲瓜籽,澆兩瓢糞水,割幾根山垴上的狗刺圈著,算是給它安了個(gè)窩。過(guò)不了些時(shí)日,或是一場(chǎng)春雨過(guò)后,或是某一個(gè)夜晚,它就發(fā)芽了,長(zhǎng)葉了,抽絲了,牽藤了,開(kāi)花了,鼓勁似的向上伸展開(kāi)來(lái),像個(gè)撒潑的小子,倔強(qiáng)的丫頭,鼓足了勁向上爬。只要能夠得著,爬得上,牽得住,纏得牢,它就夠上來(lái),爬上去。它爬上屋角高高的泡桐樹(shù),順著母親拉的晾曬衣服的電線,一路向前,向前,絲牽到哪里,花開(kāi)到哪里,像撒嬌的孩童,比賽似的開(kāi)花,一朵二朵三朵,一朵接一朵,十朵百朵地開(kāi)。這邊開(kāi)放那邊凋零,凋零的花朵下結(jié)下一個(gè)個(gè)嫩綠的小絲瓜,有如初生的粉嫩的嬰兒,讓人頓生憐惜之意。要不了幾天工夫,門前就掛滿了長(zhǎng)長(zhǎng)短短,或彎或直的綠月亮。這是兒時(shí)伙伴們最詩(shī)意的比喻。那凋落一地的黃絲瓜花,常被我們這些孩童像珍寶一樣,一一撿回來(lái)造屋兒玩。那黃黃的,柔柔的,卷曲的絲瓜花,多像母親打的泡蛋湯或炒的蛋籽兒,我們幾個(gè)伙伴兒圍在一個(gè)屋角里,造屋兒,學(xué)著母親的樣子,做一個(gè)能干賢惠的家庭主婦,在幾口火磚扛成的瓦片鍋上炒蛋籽兒,打泡蛋湯,有小主婦的滿足,有天真無(wú)邪的樂(lè)趣,有望梅止渴的幸福。那時(shí),農(nóng)村日子是清貧的,吃雞蛋是件幸福的事兒。母親總是把絲瓜變著花樣做給我們吃,嫩的就做成絲瓜湯,滑嫩可口,特別是喝到見(jiàn)底的那細(xì)細(xì)的,亮亮的,滑滑的絲瓜籽兒,最是美味。老得刨不動(dòng)皮的絲瓜,母親就加幾個(gè)辣椒連皮清炒,辣和和,也挺下飯。村里的剛子,有一回在我家吃到母親清炒的老絲瓜,“嘖嘖”直嘆好吃。因?yàn)樗胰硕嘧扉煟越z瓜,總是加一大鍋水煮,一人分一瓢清絲瓜湯。那時(shí),農(nóng)村的日子雖窮,絲瓜的味卻盡在一鍋湯里,因?yàn)橛心阋豢冢陀形乙豢冢蠹叶加幸豢冢@樣的日子雖窮,湯雖清,卻能喝出溫暖熱氣來(lái)。⑤爬得最高的絲瓜,往往蓄的時(shí)間最久,因?yàn)樗赖米罡撸粔颍赣H干脆讓它蓄老,做絲瓜種。它高高地吊在泡桐樹(shù)上打秋千,幾場(chǎng)秋風(fēng)秋雨過(guò)后,它就沒(méi)了顏色,空了皮囊。母親把鐮刀綁在桿子上把它割下來(lái),剖開(kāi)取籽做種,絲瓜瓤用來(lái)洗碗或洗澡。母親每每說(shuō),絲瓜真是個(gè)寶呀,不但好吃,吃的時(shí)間長(zhǎng),養(yǎng)活一家人,這絲瓜瓤還好用,去污強(qiáng)呢。⑥“種瓜東井上,冉冉自逾垣,瓜葛相結(jié)連,蔓延自登垣。”這首小詩(shī)既是對(duì)絲瓜的勾勒。鄉(xiāng)野的房前屋后,田田畈畈,溝頭井邊,只要有一口井,有一坯泥,那里就是絲瓜容身之所,扎根之地,哪里有陽(yáng)光,它就往哪里爬,哪里牽……⑦我愛(ài)牽到我家的絲瓜花。我愛(ài)這以絲瓜花為背景的平凡人生。15、第①自然段中,畫線句用了什么修辭手法?有怎樣的表達(dá)效果?(4分)_____________________________________________________________________________16、分析句中加點(diǎn)詞語(yǔ)的作用。(3分)母親每年總是在家門前的水溝邊上丟幾粒絲瓜籽,澆兩瓢糞水,割幾根山垴上的狗刺圈著,算是給它安了個(gè)窩。_____________________________________________________________________________17、 第④自然段結(jié)尾“這樣的日子雖窮,湯雖清,卻能喝出溫暖熱氣來(lái)”一句在寫法上有什么特點(diǎn)?又有怎樣的深刻含義?(3分)_____________________________________________________________________________18、文章結(jié)尾作者說(shuō)的“以絲瓜花為背景的平凡人生”,從選文看,以絲瓜花為背景的平凡人生具有哪些特點(diǎn) 請(qǐng)用自己的話概括回答。(4分)_____________________________________________________________________________(六)(10分)19、根據(jù)課文默寫(10分)①學(xué)而時(shí)習(xí)之, (《論語(yǔ)》八則)② ,札札弄機(jī)杼。(《古詩(shī)十九首》)③ ,志在千里。(曹操《龜雖壽》)④臨風(fēng)一唳思何事, (白居易《池鶴》)⑤ ,我言秋日勝春朝。(劉禹錫《秋詞》)⑥中庭地白樹(shù)棲鴉, 。(王建《十五夜望月》)⑦雨昏青草湖邊過(guò), 。(鄭谷《鷓鴣》)⑧ ,柳暗花明又一村。(陸游《游山西村》)⑨傷心秦漢經(jīng)行處, 。(張養(yǎng)浩《山坡羊潼關(guān)懷古》)⑩ ,化作春泥更護(hù)花(龔自珍《己亥雜詩(shī)》)三、 表達(dá)與交流 (共66分)(一)(6分)20、 今年四月,浙江衛(wèi)視的“中國(guó)星跳躍”、江蘇衛(wèi)視的“星跳水立方”等節(jié)目都邀請(qǐng)明星跳水,收視率一路攀高,獲得許多人的高度評(píng)價(jià);但由于在訓(xùn)練中釋小龍的助手溺水而死,也招致有些觀眾對(duì)衛(wèi)視提出批評(píng),國(guó)家廣電總局也要求該節(jié)目暫緩播出。你會(huì)怎樣看待這檔節(jié)目呢?請(qǐng)說(shuō)出你的觀點(diǎn)并談?wù)劺碛伞?br/>要求 ①觀點(diǎn)明確。 ②要作簡(jiǎn)要論證。 ③字?jǐn)?shù)在100字左右。(二)作文(60分)21 、 閱讀下面的文字,根據(jù)要求作文。(60分)《現(xiàn)代漢語(yǔ)辭典》:[留心]:注意。 有人曾經(jīng)說(shuō)過(guò):處處留心即學(xué)問(wèn)。 魯迅先生在談到創(chuàng)作時(shí)說(shuō)過(guò)這樣的意思:要留心身邊各種各樣的人和事。 竺可楨《唐宋詩(shī)中的物候》:唐宋詩(shī)人熱愛(ài)大自然,善于領(lǐng)會(huì)鳥(niǎo)語(yǔ)花香的暗示,他們初春留心的是燕子,暮春、初夏注意的是杜鵑、布谷…… 以“學(xué)會(huì)留心”為題目,聯(lián)系生活實(shí)際,寫一篇不少于600字的作文。體裁不限(詩(shī)歌、戲劇除外),不要出現(xiàn)自己的姓名和校名。初三語(yǔ)文模擬考試參考答案②威王派淳于髡到趙國(guó)去請(qǐng)救兵,帶上贈(zèng)送的禮品黃金百斤。(注意“使”“之”“赍”的解釋)(2分)10、①描繪了春天的早晨嘉興城外春風(fēng)和暢、春水蕩漾、春草繁茂的景象。(2點(diǎn)即可) (2分)②“過(guò)”,寫出了菜花之盛,香氣之濃郁。抒發(fā)了作者對(duì)春日融融、充滿生機(jī)的美好自然春光的欣賞贊美之情。(2分)11、作比較(1分),把當(dāng)前金融危機(jī)與其它周期性危機(jī)進(jìn)行比較,更準(zhǔn)確(突出)地說(shuō)明了當(dāng)前的金融危機(jī)的實(shí)質(zhì)。(1分)分)19、(略)20、(略)21、作文建議切入分47分江蘇省無(wú)錫市前洲中學(xué)2013屆九年級(jí)二模數(shù)學(xué)試題 2013.5注意事項(xiàng):1.本試卷滿分130分,考試時(shí)間為120分鐘. 2.卷中除要求近似計(jì)算的結(jié)果取近似值外,其余各題均應(yīng)給出精確結(jié)果.3.所有的試題都必須在答題紙上作答,在試卷或草稿紙上答題無(wú)效.一、選擇題(本大題共10小題,每小題3分,共30分.在每小題所給出的四個(gè)選項(xiàng)中,只有一項(xiàng)是正確的,請(qǐng)把選項(xiàng)直接填在答題紙上相應(yīng)的位置處)1.9的算術(shù)平方根等于 ( ▲ )A.3 B.
